Background: Industry funding and corporate sponsorship have played a significant role in the advancement of orthopaedic research and technology. However, this relationship raises concerns for how industry association may bias research findings and influence clinical practice. Purpose: To determine whether industry affiliation plays a role in the outcomes of randomized controlled trials (RCTs) investigating platelet-rich plasma (PRP). Study Design: Meta-analysis; Level of evidence, 2. Methods: A search of the PubMed, Cochrane, and MEDLINE databases for RCTs published between 2011 and the present comparing PRP versus hyaluronic acid, corticosteroid, or placebo for the treatment of knee osteoarthritis was performed. To determine industry affiliation, the conflict of interest, funding, and disclosure sections of publications were assessed, and all authors were assessed through the American Academy of Orthopaedic Surgeons disclosure database and the Centers for Medicare & Medicaid Services open payments database. Studies were classified as industry affiliated (IA) or non–industry affiliated (NIA). The outcomes of each study were rated as favorable, analogous, or unfavorable according to predefined criteria. Results: A total of 37 studies (6 IA and 31 NIA) were available for analysis. Overall, 19 studies (51.4%) reported PRP as favorable compared with other treatment options, while 18 studies (48.6%) showed no significant differences between PRP and other treatment methods. There was no significant difference in qualitative conclusions between the IA and NIA groups, with the IA group having 3 favorable studies and 3 analogous studies and the NIA group having 16 favorable studies and 15 analogous studies ( P = .8881). When comparing IA versus NIA studies using 6- and 12-month Western Ontario and McMaster Universities Arthritis Index and International Knee Documentation Committee scores, there were no significant differences in outcomes. Conclusion: The results of this study demonstrated that qualitative conclusions and outcome scores were found to not be associated with industry affiliation. Although the results of this study suggest that there is no influence of industry involvement on RCTs examining PRP, it is still necessary to carefully evaluate pertinent commercial affiliations when reviewing recommendations from studies before adopting new treatment approaches, such as the use of PRP for knee osteoarthritis.

Intraoperative medial collateral ligament (MCL) injury during total knee arthroplasty (TKA) is a serious complication. External bracing and/or conversion to a constrained implant has previously been studied. The technique of using an internal high-strength suture brace to augment an MCL repair has been evaluated in the nonarthroplasty patient and could provide an alternate solution. The goal of this study was to determine whether MCL repair with internal suture bracing restores stability of the implanted knee joint. A robotic simulator completed laxity testing on 5 cadaveric knee specimens in 4 sequential phases: (1) intact knee, (2) after implantation with TKA, (3) after sectioning of the MCL, and (4) after MCL repair with suture brace augmentation. Laxity was compared between the different test phases throughout range of motion. Subsequently, the internal brace was tested to failure under valgus load. The MCL repair with internal bracing was effective at restoring laxity in varus-valgus, internal-external, and medial-lateral degrees of freedom through midflexion, with limited support at deeper flexion angles and in anterior-posterior laxity. Rotational laxity was not significantly different than intact knee laxity. Generally, medial-lateral translations were less and anterior-posterior translations were greater and were significantly different at 30° to 45° and 90°, respectively. The mean failure moment was 46.4±9.1 Nm, with the primary mode of failure being MCL repair. Primary MCL repair with internal bracing using a high-strength suture augment showed the potential to provide adequate stability and strength to correct MCL incompetence in TKA without the use of an external knee brace or constrained implants.

Background:Digital technology has emerged as a useful tool for preoperative and postoperative patient engagement and for remote patient monitoring. Smartphones are equipped with motion-sensing technology, and apps can be designed which use these features to create a simple method for measuring range of motion. The purpose of this study was to determine the accuracy of digital technology in assessing knee range of motion using a smartphone app, compared to traditional goniometric measurements in an office setting.Methods:Fifty-three (53) patients in a clinical practice were enrolled between October 2019 and March 2020. Three separate measurements were taken during the patient encounter: (1) the surgeon, (2) the app, and (3) the physical therapist. Intraclass correlations were computed to assess the agreement between (1) the surgeon and app and (2) that between the physical therapist and surgeon.Results:When measuring flexion, the correlation between either the surgeon or therapist with the app was good, whereas the comparison between the surgeon and therapist was moderate. All extension measurement comparisons, between the app, surgeon, and therapist, showed moderate correlation. Limits of agreements showed that 80% of the difference between surgeon and app is within 10 degrees for extension and 11 degrees for flexion. Body mass index did not affect the accuracy of the measurements.Conclusion:Digital app measurements were comparable to measurements made by either a surgeon or physical therapist with a manual goniometer in the clinical setting and may be beneficial for measuring and monitoring patients' range of motion remotely.

Background: No study has specifically evaluated how ulnar neuritis and ulnar nerve transposition affect outcomes in baseball players undergoing ulnar collateral ligament (UCL) reconstruction (UCLR). Purpose: To evaluate the effects of ulnar neuritis and ulnar nerve transposition in baseball pitchers undergoing UCLR in regard to return to sport, time to return to sport, and need for revision or additional surgery. Study Design: Cohort study; Level of evidence, 3. Methods: At a single institution, all consecutive baseball pitchers undergoing UCLR between 2002 and 2015 were identified. Ulnar neuritis was diagnosed preoperatively by the following criteria: ulnar nerve symptoms, Tinel sign at the elbow, symptomatic subluxation, and numbness/paresthesia in an ulnar nerve distribution of the hand. The primary outcome of the study was return to sport. The secondary outcomes of the study were time to return to sport, length of playing career, and revision or additional surgery. Results: A total of 578 UCLRs were performed in baseball players; of these, 500 UCLRs were performed in pitchers. Ulnar neuritis was diagnosed in 97 (19.4%) baseball pitchers presenting with UCL injury. There were no significant differences in patient characteristics or surgical techniques performed for reconstruction between baseball pitchers with and without ulnar neuritis. In review of injury characteristics, ulnar neuritis was significantly more likely to be diagnosed in pitchers with an acute onset of UCL injury (P = .03). Transposition of the ulnar nerve was more commonly performed in players with ulnar neuritis (47%) versus those without ulnar neuritis (10%; P = .0001). The players who had ulnar neuritis and underwent UCLR had a significantly lower odds of returning to sport (odds ratio, 0.45; P = .04); however, no significant difference was found for time to return to sport and length of playing career for those with and without ulnar neuritis (P = .38 and .51, respectively). Conclusion: The study suggests that ulnar neuritis, when present preoperatively in baseball pitchers undergoing UCLR, may adversely affect their ability to return to sport, whereas ulnar nerve transposition at the time of UCLR does not alter the ability to return to sport.

Background: Digital patient engagement has been suggested as a mean to increase patient activation and patient satisfaction after total joint arthroplasty. The purpose of this study was to assess patient engagement with application-based educational tools and to explore what content was most useful to patients in the perioperative period surrounding total hip arthroplasty (THA) and total knee arthroplasty (TKA), respectively. Methods: Patients undergoing THA and TKA between October 2017 and January 2020 were enrolled to use an application-based digital technology. The App provides comprehensive patient education using a series of modules delivered at set intervals preoperatively and postoperatively. Patient engagement was defined as patients viewing at least one time the modules that were sent, or marking them as completed. Patient satisfaction was assessed using an in-application survey. Results: Complete data were available on 207 patients of which 95 (46%) underwent THA and 112 (54%) underwent TKA. The average age was 60 years. 54% with patients invited to the program completed registration. An average compliance rate of 48% (41 modules engaged out of 83) was observed. Of all modules completed, the top three most popular categories included physical therapy/exercise videos, health literacy, and anxiety/stress/pain management. The least viewed category was nutrition planning and education. Conclusion: When presented educational material related to THA and TKA, patients had a high rate of compliance. Digital technology platforms provide a scalable, meaningful approach to engaging patients throughout the continuum of joint replacement care and may serve as a cost-effective adjunct to traditional methods.

BACKGROUND:Return to play and player satisfaction have been quite high after ulnar collateral ligament reconstruction (UCLR); however, there has been little reported on how outcomes are affected by surgical technique, graft type, and tear characteristics. PURPOSE:To evaluate surgical techniques, graft type, and tear characteristics on Major League Baseball (MLB) performance after UCLR. STUDY DESIGN:Cohort study; Level of evidence, 2. METHODS:MLB pitchers who underwent primary UCLR at a single institution were included. Tear characteristics included tear location, tear grade, and acuity. Surgical technique and graft type were also collected. Pitching performance statistics, including earned run average (ERA), walks and hits per innings pitched (WHIP), innings pitched, and fastball velocity were evaluated 3 years before and after UCLR. RESULTS:Forty-six MLB pitchers were identified as having primary UCLR. Return to play was 96%, with 82% returning to MLB play. Technique performed showed no difference in performance. As compared with pitchers with gracilis grafts, pitchers with palmaris grafts were younger ( P = .043), played longer after surgery ( P = .012), and returned to play at 100% (35 of 35) versus 82% (9 of 11, P = .010). When compared with pitchers with proximal tears, pitchers with distal tears pitched at higher velocity (93.0 vs 90.6 mph, P = .023) and had better performance before surgery (ERA, P = .003; WHIP, P = .021); however, those with proximal tears improved to match this performance and velocity after reconstruction. As compared with those having partial tears, pitchers with complete tears played longer after surgery (5.9 vs 4.0 years, P = .033), had a better ERA before injury ( P = .041), and had better WHIP ( P = .037) and strikeouts per 9 innings ( P = .025) after reconstruction. Pitchers with chronic tears had a significant improvement in postoperative ERA, from 4.49 to 3.80 ( P = .040). CONCLUSION:Technique performed and graft type used did not affect performance; however, pitchers with palmaris grafts returned at a higher rate than those with gracilis grafts. Distal tears occurred in pitchers with greater velocity and better performance before injury, yet pitchers with proximal tears matched this performance after reconstruction. Pitchers with complete tears played longer after reconstruction. Pitchers who had partial tears had worse performance before injury and after reconstruction, and those with chronic tears saw a significant improvement in ERA with reconstruction.

BACKGROUND:Medicare reimbursements have been tied to patient satisfaction measures. Despite these measures' influence on reimbursements, the relationship between pain management and patient satisfaction remains unclear. This study aims to evaluate the relationship between traditional patient perception of pain control and their overall satisfaction after joint replacement.METHODS:This study is a retrospective review of consecutive primary total hip and total knee replacements. A total of 286 patients who underwent primary total hip (N = 106) and total knee (N = 196) replacements with completed Hospital Consumer Assessment of Healthcare Providers and Systems surveys were evaluated. Pain control, communication, and hospital satisfaction were stratified into satisfactory or unsatisfactory groups. These 2 groups were compared in terms of visual analog scale (VAS), opioid use in morphine equivalents, length of hospital stay, anesthesia type, and demographics.RESULTS:Average VAS and opioid use did not differ between patient groups for any of the questions evaluated. Those who responded "always" to pain domain questions had a statistically shorter length of stay compared to patients with other response. On average, those who endorsed "always" on communication question were younger.CONCLUSIONS:Patients who endorsed satisfactory pain control and communication with staff had shorter lengths of stay. There was no relationship between survey scores and traditional pain control measures such as VAS and opioid use. This questions the relevance of our primary pain measures in assessing patient perception of pain control. Length of stay may be a better surrogate marker for patient satisfaction of pain control.

Context: Current perception dictates that glenohumeral internal rotation deficit (GIRD) is a chronic adaptation that leads to an increased risk of pathologic conditions in the dominant shoulder or elbow of overhead athletes. Objective: To determine whether adaptations in glenohumeral range of motion in overhead athletes lead to injuries of the upper extremity, specifically in the shoulder or elbow. Data Sources: An electronic database search was performed using Medline, Embase, and SportDiscus from 1950 to 2016. The following keywords were used: GIRD, glenohumeral internal rotation deficit, glenohumeral deficit, shoulder, sport, injury, shoulder joint, baseball, football, racquet sports, volleyball, javelin, cricket, athletic injuries, handball, lacrosse, water polo, hammer throw, and throwing injury. Study Selection: Seventeen studies met the inclusion criteria for this systematic review. Of those 17 studies, 10 included specific range of motion measurements required for inclusion in the meta-analysis. Study Design: Systematic review and meta-analysis. Level of Evidence: Level 4. Data Extraction: Data on demographics and methodology as well as shoulder range of motion in various planes were collected when possible. The primary outcome of interest was upper extremity injury, specifically shoulder or elbow injury. Results: The systematic review included 2195 athletes (1889 males, 306 females) with a mean age of 20.8 years. Shoulders with GIRD favored an upper extremity injury, with a mean difference of 3.11° (95% CI, –0.13° to 6.36°; P = 0.06). Shoulder total range of motion suggested increased motion (mean difference, 2.97°) correlated with no injury ( P = 0.11), and less total motion (mean difference, 1.95°) favored injury ( P = 0.14). External rotational gain also favored injury, with a mean difference of 1.93° ( P = 0.07). Conclusion: The pooled results of this systematic review and meta-analysis did not reach statistical significance for any shoulder motion measurement and its correlation to shoulder or elbow injury. Results, though not reaching significance, favored injury in overhead athletes with GIRD, as well as rotational loss and external rotational gain.

BACKGROUND:Ulnar collateral ligament reconstruction (UCLR) is common in the sport of baseball, particularly among pitchers. Postoperative return-to-sport protocols have many players beginning to throw at 4 to 5 months and returning to full competition between 12 and 16 months after surgery. Medial elbow pain during the return-to-throwing period often occurs and can be difficult to manage. PURPOSE:To evaluate the incidence of medial elbow pain and associations with outcomes and revision surgery during the return-to-throwing period after UCLR. STUDY DESIGN:Case-control study; Level of evidence, 3. METHODS:Between the years of 2002 and 2014, all pitchers who underwent UCLR at a single institution were identified. Charts were reviewed for incidence of medial elbow pain during return to throwing, return to sport, and subsequent operative interventions, including revision ulnar collateral ligament surgery. RESULTS:Of a total of 616 pitchers who underwent UCLR during the study period, 317 were included in this study. Medial elbow pain was experienced by 45.1% (143 of 317), with a mean time of complaint of 9.75 months after surgery. The groups with and without pain did not differ statistically with regard to age (pain, 20.6 years; no pain, 20.9 years) or level of competition. Of those who experienced medial elbow pain, 10.5% did not return to sport; 5.6% underwent revision UCLR; and 19.6% underwent other operative procedures at the elbow. Among those who did not experience medial elbow pain when returning to throw, 8.7% did not return to sport, with only 1.7% undergoing revision UCLR and 6.9% undergoing other operative elbow procedures. CONCLUSION:Of the pitchers evaluated in the study, approximately half reported pain during the return-to-throwing phase after UCLR. Those who experienced medial elbow pain had a higher rate of subsequent surgical intervention.

Background: Ulnar collateral ligament (UCL) reconstruction (UCLR) has shown reliable rates of return to play, with conflicting results on pitching performance after players’ return. Purpose: To evaluate Major League Baseball (MLB) pitching performance before and after UCLR performed at a single institution. Study Design: Cohort study; Level of evidence, 3. Methods: MLB pitchers (minor league players were excluded) who underwent UCLR at our institution between 2002 and 2016 were identified. Player information and return to play were determined including pitching level (MLB vs minor league) and total number of years played after surgery. Pitching performance statistics were evaluated for 3 years before surgery and for 3 years after returning to play including earned run average (ERA), walks plus hits per inning pitched (WHIP), innings pitched, wins above replacement, runs above replacement, and pitch velocity. Results: A total of 54 MLB pitchers were identified, with 46 primary and 8 revision reconstructions. The mean time to return to play was 13.8 months (primary reconstruction: 13.7 months). The majority returned to play with a 94% return rate (primary reconstruction: 96%), and 80% returned to MLB play (primary reconstruction: 82%). Three primary reconstructions required revision surgery. Pitchers played a mean of 3.2 years in MLB and 4.6 years total after surgery (39% still playing). Pitching workload and performance were maintained or improved after surgery. The preoperative ERA was 4.63 versus 4.13 after returning to play (P = .268). Fastball velocity (P = .032), ERA (P = .003), and WHIP (P = .001) worsened the first year after surgery and then improved the second year (ERA: 4.63 to 4.06 [P = .380]; WHIP: 1.35 to 1.32 [P = .221]; fastball velocity: 91.3 to 91.9 mph [P = .097]). Compared with a matched control group, pitchers who had UCLR showed improvements or maintained performance after reconstruction including improved ERA (P = .007), WHIP (P = .025), and fastball velocity (P = .006). Conclusion: MLB players experienced a high rate of return to play and previous level of play after UCLR. Pitching workload was maintained after returning to play. Pitching performance initially decreased the first year after returning and then improved or reverted to previous levels after the first year from UCLR.

PurposeAlternative modalities to optimize pain control after anterior cruciate ligament reconstruction (ACLR) are continually being explored. The purpose of this study was to compare femoral nerve block (FNB) only vs FNB with posterior capsule injection (PCI) of the knee for pain control in patients undergoing ACLR.MethodsPatients undergoing primary ACLR were randomized to receive either FNB only or FNB with PCI. Following surgery, patient's pain was evaluated in the postoperative care unit (PACU) and at home for 4days. Pain levels were measured via visual analog scale (VAS) and calculating opioid consumption. Outcomes of interest included postoperative pain levels and opioid consumption.ResultsA total of 42 patients were evaluated, with 21 patients randomized to each study arm. Outcomes showed significant pain reduction in both anterior and posterior knee VAS scores in the PACU in those that received PCI (anterior VAS: 39.6 vs 21.3 (SD=12.9), p<0.01; posterior VAS: 25.4 vs 15.3 (SD=8.05), p=0.01). Moreover, the PCI group also showed significantly less opioid consumption compared to FNB only (23.5 vs 17.4pills, p=0.03). There were no differences found in pain scores between groups in home VAS sores.ConclusionsThese finding suggest the use of arthroscopically assisted injection of local anesthetic to the posterior capsule of the knee significantly reduces early post-operative pain and dramatically reduces the number of opoid medication taken after ACLR.Level of evidenceProspective, randomized, control trial, Level I.

Background: Venous thromboembolism (VTE) is a significant perioperative risk with many common orthopaedic procedures. Currently, there is no standardized recommendation for the use of VTE prophylaxis during anterior cruciate ligament (ACL) reconstruction. This study sought to evaluate the current prophylactic practices of fellowship-trained sports medicine orthopaedic surgeons in the United States. Hypothesis: Very few surgeons use perioperative VTE prophylaxis for ACL reconstructive surgery. Study Design: Survey. Methods: Surveys were emailed to the alumni networks of 4 large ACGME-accredited sports medicine fellowship programs. Questions were focused on their current use of chemical and nonchemical VTE prophylaxis. Results: Surveys were completed by 142 surgeons in the United States, yielding a response rate of 32%. Of those who responded, 50.7% stated that they routinely use chemical prophylaxis, with 95.5% of those using aspirin (acetylsalicylic acid [ASA]). There was no standardized dosing protocol, with respondents using ASA 325 mg once (46%) or twice daily (26%) or ASA 81 mg once (18%) or twice (10%) daily. The most common reason for not including chemical prophylaxis within the reconstruction procedure was that it is unnecessary given the low risk of VTE. Physicians also based their prophylaxis regimen more on their own clinical experience than concern for litigation. Conclusion: Half of all sports medicine fellowship–trained surgeons surveyed routinely use chemical VTE prophylaxis after ACL reconstruction, with more than 90% of those using ASA. Of those using ASA, there was no prevailing dosing protocol. For those not using chemical prophylaxis, the most important reason was that it was felt to be unnecessary due to the risks outweighing the benefits. Those who do not regularly use chemical prophylaxis would be willing to, however, if a patient had a personal or family history of clotting disorder or is currently on birth control. Additionally, clinical experience was the primary driver for a current prophylaxis protocol. Clinical Relevance: This survey study evaluating the use of VTE prophylaxis with ACL reconstruction lends clinical insight to the current practice of a large, geographically diverse group of fellowship-trained sports medicine orthopaedic surgeons in the United States.

Objectives: Operative repair of distal biceps tendon ruptures have shown successful outcomes. However, little is know about the amount of tendon or repair site lengthening after repair and how this may affect strength. The purpose of our study was to evaluate distal biceps tendon repair via radiostereometric analysis and correlate with final strength changes. Methods: Eleven patients with distal biceps ruptures were recruited. During repair, two 2-mm tantalum beads with laser-etched holes were sutured to the distal biceps tendon. Beads were evaluated via CT scans immediately post-operatively and at 16 weeks. X-rays were obtained at time 0 and then at 4, 8, and 16 weeks. Seven patients were available for final strength testing at minimum of 9 months postoperative. Results: The mean amount of tendon lengthening after surgery was 22.8 mm (range 11.2 - 30.9 mm, p < 0.05). The greatest change in lengthening was noted between time 0 and week 4 (mean: 11.3 mm, p<0.05), with the least amount of lengthening between week 8 and week 16 (mean: 2.6 mm, p<0.05). DASH averaged 8.2. Strength testing performed at final follow-up (n=7) showed 78% supination and 88% flexion strength compared to contralateral side (33% with dominant arm repaired). Supination strength loss showed the greatest decreases with increased lengthening from 0-4 weeks (Correlation coefficient: -0.39). Final ultrasound evaluations found all tendons to be in continuity. Conclusion: This study’s findings suggest that all patients undergoing distal biceps tendon repair have significant lengthening after surgery. The greatest amount of lengthening was noted in the early post-operative period, in which the greater the amount of lengthening trended toward a greater loss of supination strength. Further studies will focus on post-operative protocols as they may have an impact on early tendon lengthening and could be adjusted to minimize this consequence on long-term supination strength.

Background: Literature has attempted to correlate pitching workload with risk of ulnar collateral ligament (UCL) injury; however, limited data are available in evaluating workload and its relationship with the need for revision reconstruction in Major League Baseball (MLB) pitchers.Methods: We identified 29 MLB pitchers who underwent primary UCL reconstruction surgery and subsequently required revision reconstruction and compared them with 121 MLB pitchers who underwent primary reconstruction but did not later require revision surgery. Games pitched, pitch counts, and innings pitched were evaluated and compared for the seasons after returning from primary reconstruction and for the last season pitched before undergoing revision surgery.Results: The difference in workload between pitchers who did and did not require revision reconstruction was not statistically significant in games pitched, innings pitched, and MLB-only pitch counts. The one significant difference in workload was in total pitch counts (combined MLB and minor league), with the pitchers who required revision surgery pitching less than those who did not (primary: 1413.6 pitches vs. revision: 959.0 pitches, P = .04). In addition, pitchers who required revision surgery underwent primary reconstruction at an early age (22.9 years vs. 27.3 years, P < .001) and had less MLB experience (1.5 years vs. 5.0 years, P < .001).Conclusions: There is no specific number of pitches, innings, or games that place a pitcher at an increase risk for injury after primary UCL reconstruction. However, correlations of risk may be younger age and less MLB experience at the time of the primary reconstruction. (C) 2017

Objectives: To determine the rate and timing of return to NFL play after a shoulder instability event and to determine what factors predict ability to Return to Play (RTP). Methods: A total of 83 NFL players who sustained an in-season shoulder instability event while playing in the NFL were identified and evaluated. Return to NFL play, incidence of surgery, time to return, recurrent instability events, seasons and games played after injury, and demographic data were collected. Overall RTP was determined and players who had surgery were compared to those who did not have surgery. Playing time after RTP was compared with age, position, size and experience matched control players. Results: Ninety-one percent of NFL players returned to NFL regular season play at an average of 1.6 ± 1.9 weeks (mean ± SD) in those sustaining a shoulder subluxation and 3.7 ± 5.4 weeks in those sustaining a dislocation; p = .53. In players who were able to RTP without surgery, those having a left shoulder instability event were able to return faster (1 week) than those having a right shoulder event (4 weeks); p = .03. A majority of players (62%) underwent surgical stabilization and 86% returned to play the following season. Players who had surgery were more likely to have a second instability event in their career (58% versus 9%); p = .01. No difference was found when comparing playing time after return with matched controls. Conclusion: There is a high rate of RTP following shoulder instability events in NFL players. Players sustaining subluxations in their non-dominant arm return to play at a faster rate. Surgical stabilization of the shoulder following an instability event may not ly eliminate potential for subsequent recurrent events as a high percentage of surgically treated players were found to have another instability event.

Background: National Football League (NFL) players who undergo anterior cruciate ligament (ACL) reconstruction have been shown to have a lower return to play (RTP) than previously expected. However, RTP in the NFL after revision ACL reconstruction (RACLR) is not well defined.Purpose/Hypothesis: The purpose of this study is to determine the RTP of NFL players after RACLR and evaluate factors that predict RTP. Our hypothesis was that more experienced and established players would be more likely to RTP after RACLR.Study Design: Cohort study; Level of evidence, 3.Methods: A total of 24 NFL players who underwent RACLR between 2007 and 2014 were reviewed and evaluated. Return to NFL play, time to return, seasons and games played prior to and after revision surgery, draft status, and demographic data were collected. Overall RTP was determined, and players who did RTP were compared with those unable to RTP. Data were also compared with control players matched for age, position, size, and experience.Results: After RACLR, 79% (19/24) of NFL players returned to NFL regular-season play at an average of 12.6 months. All players who were drafted in the first 4 rounds, played in at least 55 games, or played 4 seasons of NFL play prior to injury were able to RTP. Players drafted in the first 4 rounds of the NFL draft were more likely to RTP than those who were not (odds ratio, 0.1; 95% CI, 0.01-1.00; P = .05). Those who returned to NFL play played in significantly less games and seasons after their injury than before (P = .01 and P = .01, respectively). However, these values did not differ when compared with matched controls (P = .67 and P = .33).Conclusion: NFL players who RTP after RACLR do so at a similar rate but prolonged time period compared with after primary ACL reconstruction. Athletes who were drafted in earlier rounds were more likely to RTP than those who were not. Additionally, player experience prior to injury is an important factor when predicting RTP after RACLR.

Background: With an increasing number of Major League Baseball (MLB) players undergoing ulnar collateral ligament (UCL) reconstruction, there remains limited literature on appropriate post-reconstruction workload management to limit the risk of reinjury.Methods: A total of 28 MLB pitchers who underwent primary UCL reconstruction surgery and subsequently required revision reconstruction were identified and compared with 137 MLB pitchers who underwent primary reconstruction but did not later require revision surgery. Games pitched, pitch counts, and innings pitched were evaluated and compared 3 years before and after primary reconstruction.Results were then compared between groups. Results: Pitchers who later required revision increased their games pitched by 14.1% after reconstruction whereas the no-revision group pitched 13.6% fewer games than before reconstruction (P <.01). Inning workload was reduced by 9.8% after surgery (89.8 innings after vs 99.6 innings before) for the revision group compared with the no-revision group, which threw 26% fewer innings after surgery (86.3 innings after vs 116.7 innings before) (P =.05). In addition, the revision group pitched 6.6% more pitches after reconstruction, 1138.9 pitches, compared with before reconstruction, 1068.6 pitches. Pitchers who did not require revision, in contrast, pitched 19.6% fewer pitches after reconstruction than before reconstruction (P =.08).Conclusions: This study's findings suggest that MLB pitchers who require revision UCL reconstruction after returning to play following primary UCL reconstruction pitch at or above their pre-primary UCL reconstruction workload whereas control pitchers who do not require revision pitch significantly less, below their pre-primary UCL reconstruction workload.Level of evidence: Level III; Retrospective Cohort Design; Treatment Study (C) 2017 Journal of Shoulder and Elbow Surgery Board of Trustees.

Purpose: To determine if patients treated with a single-shot femoral nerve block have strength and functional deficits at 9-month follow-up. Methods: Forty-three patients who underwent primary anterior cruciate ligament reconstructions were randomized to receive either a preoperative single-shot femoral nerve block or local infiltration anesthesia for primary pain control. All patients underwent a standardized comprehensive rehabilitation program postoperatively. Isokinetic strength and function was tested using a Biodex machine at 9 months or more postoperatively comparing the operative and nonoperative extremity. Results: No significant difference in strength was found at an average of 10.6 months postoperatively (range, 9-15 months) between the femoral nerve block and control groups. In comparing strength deficits, we found no difference in slow isokinetic extension strength (22.4% vs 27.8%, P = .51), fast isokinetic extension strength (18.5% vs 12.5%, P = .41), slow isokinetic flexion strength (11.0% vs 15.1%, P = .55), and fast isokinetic flexion strength (8.2% vs 4.9%, P = .56) in the femoral nerve block versus control groups, respectively. In terms of functional outcomes, there also was no difference in deficits for single-leg hop distance (P = .12), timed single-leg hop (P = .74), and single-leg triple hop distance (P = .94). Maximal strength noted to be within 15% of the contralateral limb was achieved in 40% of patients and maximal function in 63% of patients at an average of 10.6 months postoperatively. A 13% complication rate was found in patients who received a femoral nerve block (1 with prolonged quadriceps inhibition and 2 with prolonged sensory disturbances). Conclusions: Our study found a 13% motor/sensory complication rate in patients who underwent femoral nerve block for pain control after anterior cruciate ligament reconstruction. Although these deficits may persist, they are not permanent and are not different when compared with controls at 9-month follow-up. However, maximal strength and function are not fully restored at normal return to play time and rehabilitation should continue long term to maximize recovery.

The ulnar collateral ligament (UCL) is an important medial stabilizer of the elbow, particularly in overhead-throwing athletes. However, there is no universally accepted method for evaluating UCL thickness with ultrasound (US).

Historically, patient perceptions of surgeon reimbursement have been exaggerated compared with actual reimbursement. There is limited information about patient perceptions of physician reimbursement for arthroscopic meniscectomy and anterior cruciate ligament (ACL) reconstruction. This study evaluated patient perceptions of physician reimbursement for these procedures and compared perceptions of health care reform between urban and suburban clinics. Surveys were given to 231 consecutive patients, and patients were asked how much they believed a surgeon should be reimbursed for arthroscopic meniscectomy and ACL reconstruction as well as their perception of actual Medicare reimbursement to physicians. Patients were then informed of the actual reimbursement rates and asked additional questions about health care reform. Survey responses were compared in an urban setting vs a suburban setting. On average, patients reported that surgeons should receive $8096 for meniscectomy and $11,794 for ACL reconstruction. Patients estimated that Medicare paid physicians $5442 for meniscectomy and $6667 for ACL reconstruction. In addition, 65% of patients believed that reimbursement for meniscectomy was too low, and 57% of patients believed that reimbursement for ACL reconstruction was too low. Fewer than 2% of patients believed that surgeon salaries should be cut, and 75% believed that orthopedic surgeons should be paid more for subspecialty training. No differences were found in patients' perceptions of reimbursement or health care reform between urban and suburban settings. Patients perceived that the values of meniscectomy and ACL reconstruction were substantially higher than current Medicare reimbursement values and that surgeon salaries should not be cut.
