Compare postoperative opioid consumption following hip arthroscopy in patients who received a preoperative, lateral quadratus lumborum block versus those who did not. Patients were retrospectively identified. The primary outcome was postoperative opioid consumption (IV morphine milligram equivalents) in patients with and without a block. Comparisons between groups were conducted with Chi-square tests and Fisher Exact Tests where appropriate. Continuous data were compared with two-sided t-tests and Wilcoxon rank-sum tests. Data were collected on 100 patients. Mean (95% confidence interval) postoperative opioid consumption was reduced in patients with a quadratus lumborum block compared to those without a block (6.6 [5.2 - 8.1] vs 11.8 [10.2 - 13.4]; p < 0.0001; respectively). Eleven percent of patients with a preoperative quadratus lumborum block did not consume any opioids in the post anesthesia care unit. Opioid consumption in the immediate postoperative period was significantly reduced in patients that received a preoperative quadratus lumborum block.

Hypothesis:The purpose of this study was to perform a systematic review of the available literature evaluating surgical outcomes after chronic distal biceps tendon rupture. Surgical techniques, including primary repair, autograft reconstruction, and allograft reconstruction, were compared, as well as subjective and objective clinical outcomes and complication rates.Methods:A systematic literature search of Level I-IV studies reporting outcomes of surgically treated chronic distal biceps tendon ruptures were performed via PubMed, Cochrane Collaboration, Science Direct, and Google Scholar databases. Twenty-two papers were identified in the review, with 236 patients. A Modified Coleman Methodological Score (CMS) was determined for every article to assess study quality. Patient-reported outcomes, postoperative range of motion, flexion and supination strength, and postoperative complications were recorded. MAYO elbow scores (MEPS) were reported more consistently than the other outcome tools.Results:No Level I or level II studies were identified in our search, and the heterogeneity of outcome measures precluded meta-analysis. Studies demonstrated mean MEPS scores ranging between 86 and 100, regardless of the surgical technique utilized. All studies reported a mean flexion-extension arc equal to or greater than 5-130°. The reported mean postoperative flexion strength was within 10% of the unaffected contralateral side. The most common complication for both direct repair and reconstruction groups was paresthesia of the lateral antebrachial cutaneous nerve [direct repair: 18-16.8%; reconstruction: 8-6.2% (allograft: 4-6%; autograft: 4-7%)]. Rerupture was uncommon and occurred in three patients who had undergone direct repair and in one patient after autograft reconstruction.Conclusions:Surgical treatment of chronic distal biceps injuries yields favorable objective and subjective outcomes. Currently, available evidence suggests that direct repair, autograft reconstruction, or allograft reconstruction are all viable treatment options with similar outcomes.

INTRODUCTION:The purpose of this study was to evaluate nationwide trends and regional variability in opioid prescriptions after common orthopaedic procedures. METHODS:A retrospective analysis of privately insured subjects from the MarketScan database between 2015 and 2016 was conducted. Median oral morphine equivalents and interquartile ranges were analyzed by region for the initial post-op prescriptions and 90-day total prescriptions for opioid-naive patients undergoing the following: carpal tunnel release; anterior cruciate ligament reconstruction; arthroscopic meniscectomy; bimalleolar ankle fracture open reduction and internal fixation; distal radius fracture open reduction and internal fixation; arthroscopic rotator cuff repair; single-level anterior cervical discectomy and fusion; and total shoulder, hip, and knee arthroplasties. We hypothesized that notable regional variability exists with postoperative narcotic prescribing habits. RESULTS:Seventy three thousand nine hundred twenty-one opioid-naive patients were identified. A notable regional variability was observed across the United States in the prescriptions given for all procedures, except total joint arthroplasty. Furthermore, although patients undergoing soft-tissue-only procedures required the fewest refills, patients undergoing total joint arthroplasty required the most. DISCUSSION:Notable regional variability exisits in opioid prescribing patterns for many common orthopaedic procedures. Furthermore, prescriptions were smallest in the region most affected by the opioid epidemic. This information can be used to re-evaluate recommendations, serve as a benchmark for surgeons, and develop institutional and quality improvement guidelines to reduce excess postoperative opioid prescriptions. LEVEL OF EVIDENCE:Level III observational cohort study.

CASE:A 20-year-old woman presented with recurrent bilateral shoulder instability concurrent with severe, treatment-refractory epilepsy. Imaging revealed glenoid bone loss of 25% to 28% and large Hill-Sachs defects bilaterally. Bone graft augmentation of the glenoid and infill of the Hill-Sachs defects was performed bilaterally. Perioperative neuromuscular paralysis of shoulder girdle muscles with botulinum toxin was performed to facilitate recovery. Both shoulders at 2.5 and 4 years, respectively, demonstrate excellent stability and radiographic union despite continued seizure activity. CONCLUSION:Perioperative neuromuscular paralysis with botulinum toxin may provide early graft protection after the surgical treatment of glenohumeral instability because of seizures.

Importance High-grade posterior cruciate ligament (PCL) tears can be a significant cause of patient morbidity and knee instability. The graft of choice for operative repair remains controversial, although recently there has been increased interest in quadriceps tendon (QT) as an autologous graft option. Objective The purpose of this study was to perform a systematic review to assess reported clinical outcomes of PCL reconstructions using QT autografts. Evidence review A comprehensive review of clinical studies was performed evaluating PCL reconstruction with QT autograft including a systematic search of PubMed, Scopus, Cochrane and Google Scholar databases, and reference lists of relevant papers. Clinical results, stability results, functional outcomes, range-of-motion outcomes, complications and morbidity, and the conclusions of each study were evaluated. Findings Seven studies were included in the review of clinical results, including 145 subjects undergoing PCL reconstructions with QT autograft. All studies evaluated quadriceps tendon bone (QT-B) grafts. Among these seven studies, two included isolated PCL reconstruction while five included multiligamentous knee injury reconstruction. These studies suggest that QT-B autograft offers a viable graft option for primary PCL reconstruction with generally favourable patient-reported outcomes, knee stability and range of motion reported along with relatively low complication rates. Conclusions and relevance Use of the QT-B autograft may be a reasonable graft option for PCL reconstruction. However, high-quality prospective studies are required to evaluate the long-term safety, efficacy and functional outcomes. Level of evidence Level IV (Systematic review of Level IV studies).

OBJECTIVES:COVID-19 altered National Football League (NFL) player and team training during the 2020 offseason. All preseason games were cancelled resulting in absence of game play before the first week of the regular season. Thus, concerns exist regarding injury susceptibility of players during regular season games. The purpose of this study was to evaluate and compare injury rates during the 2020 NFL season versus injury rates from the unaffected 2017-2019 seasons. We hypothesized there would be an increased injury rate and an increased rate of season ending injuries during the modified 2020 season. METHODS:The NFL's public injury database was queried to identify players placed on the injury lists throughout the 2017-2020 seasons. All players listed as "out" and on the injured reserve due to physical injury were included in the data set. For further stratification, injury incidence was separated based on position. Time missed due to COVID-19 illness was not included. Injury rates were expressed as injuries per 1000 athlete exposures (AE). RESULTS:Overall, 893 individual players missed games due to injury during the 2020 NFL regular season compared to an average of 743 over the 2017-2019 seasons. Defensive players at all positions had a statistically significant increase in injury incidence from an average of 7.54 to 10.20 injuries per 1000 AE. Defensive backs were most affected with a 46% increase in players injured. There was no statistically significant difference in season ending injuries for any position. CONCLUSIONS:The COVID-19 stricken 2020 NFL regular season saw an increased rate and incidence of injuries. Specifically, defensive players had a higher incidence of injury overall with defensive backs experiencing the greatest increase in injury rates.

The purpose of this study was to (1) report on the incidence of concurrent surgical pathology at the time of adolescent ACL reconstruction, (2) evaluate patient risk factors for concurrent pathology, and (3) measure the effect of BMI on operating room (OR) time. A retrospective analysis of the NSQIP database for the years 2005–2017 was conducted. Nine-hundred and seventeen patients 18 years of age and younger who underwent ACL reconstruction (ACLR) were identified using CPT code 29888 and patients undergoing surgery for multi-ligamentous knee injuries were excluded. The mean patient age was 17.6 years (range 14–18, standard deviation 0.52) and consisted of 546 males (59.5%) and 371 females (40.5%). Logistic regression was used to assess the relationship between BMI and additional CPT codes for internal derangement at the time of surgery. Internal derangement was defined as any procedure for the treatment of a meniscal tear, chondral lesion, or loose body removal. Linear regression analysis was then performed to evaluate the effect of BMI on operative time. 43.7% of patients undergoing ACLR required an associated procedure for internal derangement. Additionally, the risk of requiring additional procedures for internal derangement increased by 3.1% per BMI point. BMI was also predictive of operative time, independent of the number of additional procedures. Specifically, the operative time increased by nearly one minute for every point increase in BMI (58.0 s). Adolescent patients with an elevated BMI were much more likely to require additional surgical procedures for internal derangement at the time of ACL reconstruction. Additionally, BMI was a significant predictor for longer operative times. Level III.

Purpose The purpose of our study is to use the Truven MarketScan database to: 1) report the incidence of VTE, including DVT and PE, in patients undergoing simple knee arthroscopy and anterior cruciate ligament (ACL) reconstruction, and 2) evaluate combined oral contraceptive (COCP) use as a potential risk factor for VTE in patients undergoing knee arthroscopy. Methods All female patients between the ages of 16 and 40 undergoing knee arthroscopy and ACL reconstruction between 2010 and 2015 were identified in the MarketScan database. Patients were stratified by whether or not they had a documented pharmaceutical claim for COCP therapy, and the primary outcome was the risk of deep vein thromboses (DVT) and or pulmonary embolism (PE) within 90 postoperative days. Results 64,165 patients were identified for inclusion. While the overall incidence of VTE was low, patients taking COCPs had an increased risk of a DVT or PE compared to those not on COCPs (OR 2.1, p Conclusions This study demonstrates that COCP use is associated with an increased risk for a symptomatic DVT or PE (1.70% and 0.27%, respectively) after knee arthroscopy and an increased risk for DVT, but not PE (1.80% and 0.23%, respectively), after ACL reconstruction. Additionally, patients with multiple risk factors present such as tobacco use, obesity, and COCP use had odds ratios greater than the sum of the individual risk factors alone. Level of evidence level III prognostic cohort study

Hypothesis: The pm pose of this study was to evaluate the association between smoking and postoperative complications following total shoulder arthroplasty. We hypothesized that active smokers would have significantly greater postoperative medical and surgical complications. Methods: The American College of Surgeons National Surgical Quality Improvement Program database was queried for patients who underwent total shoulder arthroplasties from 2005 through 2016. Patients were stratified based on tobacco use within the past year. Logistic regression was used to assess the relationship between smoking status and postoperative medical and surgical complications. Multivariate logistic regression was used to adjust for demographic and comorbid factors. Results: We identified 14.465 patients, of whom 105% were active smokers. Smokers were more likely to be younger, to be female patients, and to have a lower body mass index compared with nonsmokers (P < .001). Univariate analysis demonstrated that smoking was not associated with postoperative medical complications (P > .05) but was associated with an increased risk of overall surgical complications (odds ratio [OR], 3.259; 95% confidence interval [CI], 1.861-5.709; P < .001). Multivariate modeling showed that smoking increased the risk of wound complications (adjusted OR, 7.564; 95% CI, 2.128-26.889; P = .002) and surgical-site infections (adjusted OR, 1.927; 95% CI, 1.023-3.630; P = .042). Discussion and conclusion: This study demonstrates that smoking is associated with an increased risk of surgical complications following total shoulder arthroplasty. On the basis of our available data, medical complications are not significantly increased. This information can help risk stratify patients prior to their procedures.

PURPOSE:To (1) determine the rate of surgical complications and venous thromboembolism (VTE) in patients undergoing arthroscopic Bankart repair, open Bankart repair, or Latarjet-Bristow; and (2) assess potential risk factors for surgical complications and VTE in patients undergoing shoulder stabilization procedures.METHODS:The NSQIP database was used to identify patients undergoing isolated surgery for shoulder instability from 2005 to 2017. Demographic data were collected and compared. Logistic regression was used to assess the risk factors for developing a postoperative complication, and regression analyses were used to evaluate the odds of postoperative complications between types of surgery.RESULTS:We identified 7,233 patients for inclusion. Patients undergoing Latarjet-Bristow were more likely to be male and Black and to report current tobacco use. Overall, there was a low rate of surgical complications (0.4%) and VTE (0.2%). However, patients undergoing Latarjet-Bristow had nearly a 10-fold increase in the risk of surgical complications compared with an arthroscopic or open Bankart repair (1.9% versus 0.2%, P < .001), including deep surgical site infections, return to operating room within 30 days, and symptomatic VTE (deep venous thrombosis rate: arthroscopic Bankart repair, 0.1%; Latarjet-Bristow, 0.8%; P < .001). There were no differences in the odds of developing a surgical complication or VTE between patients undergoing arthroscopic or open Bankart repair.CONCLUSION:This study used a nationally representative, widely validated, peer-reviewed database to demonstrate that patients undergoing a Latarjet-Bristow procedure are at significantly higher risk for short-term postoperative complications, including deep surgical site infections, return to the operating room, and symptomatic VTE, than those undergoing Bankart repair. These findings should not discourage surgeons from proceeding with a coracoid transfer procedure when indicated for glenoid deficiencies, but should inform preoperative counseling and help guide perioperative care to optimize patient outcomes.LEVEL OF EVIDENCE:III, retrospective comparative trial.

While prior studies have demonstrated that insulin-dependence is an independent risk factor for postoperative complications, morbidity, and mortality following spine and shoulder, hip, and knee arthroplasty, it has not been evaluated in the setting of knee arthroscopy. Therefore, the purpose of this study is to compare the risk of postoperative complications among patients with insulin-dependent diabetes mellitus and noninsulin-dependent diabetes mellitus (IDDM and NIDDM respectively) with the general population following knee arthroscopy. A retrospective analysis of the National Surgical Quality Improvement Program's database for the years 2005 to 2016 was conducted. Logistic regression analyses were used to assess the relationship between diabetic status and outcomes. Multivariate models were established to adjust for age, sex, body mass index, hypertension, congestive heart failure, chronic obstructive pulmonary disease, smoking status, American Society of Anesthesiology classification, and functional status. A total of 86,023 patients were identified. Patients with IDDM were at a much higher risk of surgical complications (odds ratio [OR]: 2.186, 95% confidence interval [CI]: 1.226-1.157), including deep infections (OR: 3.082, 95% CI: 1.753-5.419) and return to operating room [OR] (OR: 1.933, 95% CI: 1.280-2.919), as well as unplanned hospital admission (OR: 1.770, 95% CI: 1.289-2.431). However, NIDDM was not an independent risk factor for subsequent medical or surgical complications, unplanned hospital admission, or 30-day mortality. Patients with IDDM were much more likely to have surgical complications, including deep infection and return to OR, as well as unplanned hospital admission following knee arthroscopy. These risks diminished among those with NIDDM, with their adjusted risk profiles comparable to those without diabetes. Since diabetes occurs in a heterogenous state, more weight should be given to those with insulin-dependence when risk-stratifying patients for surgery. This is a Level III, retrospective comparison study.

PURPOSE:To use the Truven MarketScan database to (1) report the incidence of venous thromboembolism (VTE), including deep vein thromboses (DVTs) and pulmonary embolism (PE), in patients undergoing simple knee arthroscopy and anterior cruciate ligament (ACL) reconstruction, and (2) evaluate combined oral contraceptive (COCP) use as a potential risk factor for VTE in patients undergoing knee arthroscopy. METHODS:All female patients between the ages of 16 and 40 years undergoing knee arthroscopy and ACL reconstruction between 2010 and 2015 were identified in the MarketScan database. Patients were stratified by whether they had a documented pharmaceutical claim for COCP therapy, and the primary outcome was the risk of DVT and or PE within 90 postoperative days. RESULTS:In total, 64,165 patients were identified for inclusion. While the overall incidence of VTE was low, patients taking COCPs had an increased risk of a DVT or PE compared with those not on COCPs (odds ratio [OR] 2.1, P < .001). When patients were analyzed by procedural subgroup (ACL reconstruction and simple knee arthroscopy), similar results held true. Furthermore, smoking and obesity had a synergistic effect when combined with COCPs use on the risk of VTE. Specifically, 3.1% of patients with obesity on COCPs (OR 3.1, P < .001) and 4.0% of smokers on COCPs (OR 4.3, P < .001) developed a postoperative VTE. CONCLUSIONS:This study demonstrates that COCP use is associated with an increased risk for a symptomatic DVT or PE (1.70% and 0.27%, respectively) after knee arthroscopy and an increased risk for DVT, but not PE (1.80% and 0.23%, respectively), after ACL reconstruction. In addition, patients with multiple risk factors present such as tobacco use, obesity, and COCP use had odds ratios greater than the sum of the individual risk factors alone. LEVEL OF EVIDENCE:level III prognostic cohort study.

Background: Femoral nerve block (FNB) is a popular technique for reducing postoperative pain in patients with anterior cruciate ligament reconstruction (ACLR), but it is also linked to a number of adverse effects, such as quadriceps weakness, antalgic ambulation, and increased fall risk. Adductor canal block (ACB) has been offered as a motor nerve-sparing alternative to FNB. Purpose: To evaluate available literature that compares the effects of ACB and FNB on functional outcomes after arthroscopic ACLR. Study Design: Systematic review. Methods: Following the 2009 PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a search of PubMed (Ovid), CINAHL, Scopus, Cochrane, and Google Scholar databases was conducted. Search terms were designed to capture studies comparing the effects of ACB and FNB in patients undergoing arthroscopic ACLR. Data were evaluated regarding study and patient characteristics, functional measures, opioid consumption, pain scores, and complications. Results: Eight randomized controlled trials (N = 655 patients) comparing the efficacy of ACB versus FNB in arthroscopic ACLR were included. The heterogeneity of outcome measures precluded meta-analysis. Seven studies reported functional measures, which included isokinetic strength, straight-leg raise, and other various measures. Follow-up periods varied between 1 hour and 6 months. In 3 trials, ACB was found to preserve quadriceps strength as measured using straight-leg raise for the first 12 to 24 hours after surgery, while 3 other trials found no difference between the groups. No differences were reported in isokinetic strength at 6 months. In other functional measures, ACB either outperformed or was equivalent to FNB. The majority of studies reporting opioid consumption, pain scores, and complications found no differences between the blocks. Conclusion: This systematic review suggests that when compared with FNB, ACB preserves quadriceps function in the early postoperative period after ACLR while providing a similar level of analgesia. Limitations of this study include the use of various functional measures and limited long-term follow-up. More research evaluating long-term functional outcomes with standardized measures is needed to draw adequate conclusions regarding the effects of ACB and FNB on function after ACLR.

Cutibacterium Ned Propionibacterium acnes is a human skin flora often implicated in orthopedic infections. The unique characteristics of this microorganism make the diagnosis of infection difficult. The diagnosis often is made based on clinical evidence, radiographic signs, and laboratory and/or surgical findings combined,"Treatment often involves both pharmacologic and surgical methods. In addition, formation of biofilms and increased resistance to drugs exhibited by the microorganism can require combined antimicrobial therapy. Prophylactic measures are particularly important, but no single method has been shown to fully eliminate the risk of C acres infections. Previous reports have focused on C acnes infections involving surgical implants or after certain orthopedic procedures, particularly in the shoulder and spine. This article reviews current clinical, diagnostic, and treatment principles for C acnes in orthopedics in general.

Hypothesis: The purpose of this study was to evaluate the 5-factor modified frailty index (mFI-5) as a predictor of postoperative complications in patients undergoing total shoulder arthroplasty (TSA). Methods: We conducted a retrospective analysis of the National Surgical Quality Improvement Program database for patients undergoing TSA between the years 2005 and 2017. The mFI-5 score, which includes the presence of comorbid diabetes, hypertension, congestive heart failure, chronic obstructive pulmonary disease, and functional status, was calculated for each patient. Multivariate logistic regression models were used to assess the relationship between the mFI-5 and postoperative complications. Results: A total of 18,957 patients undergoing TSA were identified. The mFI-5 was a strong predictor of serious medical complications (cardiac arrest, myocardial infarction, septic shock, pulmonary embolism, postoperative dialysis, reintubation, and prolonged ventilator requirement), discharge to a facility, and readmission (odds ratio >= 1.309, P <= .001). Length of stay also increased as the mFI-5 score increased (P < .001). However, among all the measured complications, the mFI-5 was the strongest predictor of mortality, with the risk more than doubling for each point increase in the mFI-5 score (odds ratio, 2.113; 95% confidence interval, 1.447-3.086; P < .001) . Conclusion: The mFI-5 predicts serious medical complications. increased length of stay, discharge to a facility, hospital readmission, and mortality in patients undergoing TSA. All of the variables within the mFI-5 are easily obtained through the patient history, allowing for a practical clinical tool that hospitals and surgeons can use to identify high-risk surgical candidates, inform preoperative counseling, and guide perioperative care to optimize patient outcomes.

Background: After a devastating earthquake in Haiti in 2010, multiple South Carolinian orthopaedic teams, funded by the South Carolina Orthopedic Association (SCOA), developed an exchange program for Haitian residents. Methods: SCOA teams have sequentially logged their patient experiences since 2015 for a total of six updates per year. These logs were reviewed in detail to evaluate clinical results in terms of case volumes, cases performed, follow-up obtained, and complications. Results: Twenty-one orthopaedic attendings, 19 South Carolina orthopaedic residents, 22 Haitian orthopaedic residents, and 22 ancillary staff have rotated through Hospital Lumiere. The teams have seen over 2000 patients in the orthopaedic clinic and performed 554 surgeries, including 207 fractures (half of which being open), 24 nonunion and 7 malunion repairs, 15 lower extremity amputations, 27 hemiarthroplasties for femoral neck fractures, and 34 cases of chronic osteomyelitis. Discussion: The SCOA Foundation has developed a coordinated service for the musculoskeletal needs of the Haitian people while collaboratively elevating the standard of orthopaedic training in Haiti. We report a collaborative model that other US residency programs can use to impart beneficial changes not only in their home program, but also in training programs abroad.

Purpose: To compare complications after shoulder arthroscopy in patients with insulin-dependent diabetes mellitus (IDDM), patients with noneinsulin-dependent diabetes mellitus (NIDDM), and nondiabetic patients. Methods: A retrospective analysis of the American College of Surgeons National Surgical Quality Improvement Program database for the years 2005 to 2016 was conducted. Logistic regression analyses were used to assess the relation between diabetic status (nondiabetic patients, n = 50,626; NIDDM patients, n = 5,332; and IDDM patients, n = 2,484) and outcomes. Multivariate models were established to adjust for age, sex, body mass index, hypertension, congestive heart failure, chronic obstructive pulmonary disease, smoking status, American Society of Anesthesiologists classification, and functional status. Results: Patients with IDDM were at a higher risk of medical complications, with an adjusted odds ratio (AOR) of 1.524 (95% confidence interval [CI], 1.082-2.147), including pulmonary complications (AOR, 2.078; 95% CI, 1.089-3.964) and urinary tract infections (AOR, 2.129; 95% CI, 1.027-4.415). Patients with IDDM also had a higher risk of 30-day hospital admission (AOR, 1.581; 95% CI, 1.153-2.169) and 30-day mortality (AOR, 3.821; 95% CI, 1.243-11.750). Conversely, patients with NIDDM had comparable risks of medical and surgical complications, unplanned hospital admission, and death to nondiabetic patients. Conclusions: Medical complications, 30-day hospital admission, and death after shoulder arthroscopy were more likely in patients with IDDM. These risks diminished among patients with NIDDM, with their risks being comparable with those of nondiabetic patients. Level of Evidence: Level III, retrospective comparison study.

Introduction: The purpose of this study is to evaluate the utility of the modified frailty index-5 (mFI-5) as a predictor for postoperative complications in patients undergoing arthroscopic rotator cuff repair (RCR). Methods: The National Surgical Quality Improvement Program database was queried for patients undergoing arthroscopic RCR between 2006 and 2016. The mFI-5, a 5-factor score comprising comorbid diabetes, hypertension, congestive heart failure, chronic obstructive pulmonary disease, and functional status limiting independence, was calculated for each patient. Multivariate logistic regression models were used to evaluate the mFI-5 score as a predictor for complications including medical complications, surgical-site infections, hospital admission, discharge to a facility, and mortality. Results: In total, 24,477 patients met criteria for inclusion. The mFI-5 was a strong predictor for medical complications (P < .001), hospital admission (P < .001), length of stay (P = .007), and discharge to a facility (P = .001) but not surgical-site infections (P = .153). For each point increase in mFI-5 score, the risk for a medical complication increased by 66%, readmission by 52%, and adverse discharge by 45%. However, of all the measured complications, the mFI-5 was the strongest predictor for mortality, with the risk more than doubling for each increase in mFI-5 point (odds ratio 2.66, P = .025). Conclusions: The mFI-5 is a sensitive tool for predicting life-threatening medical complications, hospital admission, increased length of stay, adverse discharge, and mortality following arthroscopic RCR. The 5 comorbidities comprising the mFI-5 are easily obtained through the patient history, making it a practical clinical tool for identifying high-risk patients, informing preoperative counseling, and improving value-based health care.

Objectives: Diabetes mellitus is a growing health concern in the U.S. affecting an estimated 23.1 million citizens. While diabetes is a risk factor for complications following total joint arthroplasty, it is unclear whether this risk holds true for arthroscopy and, whether this risk is stratified by insulin-dependence (IDDM) and non-insulin dependent diabetes (NIDDM). The goal of this study is to evaluate complications following shoulder and knee arthroscopy in patients with IDDM and NIDDM. Methods: A retrospective analysis of the American College of Surgeon’s National Surgical Quality Improvement Program’s (ACS-NSQIP) database for the years 2005-2016 was conducted. Logistic regression analyses were used to assess the relationship between diabetic status and outcomes. Adjusted odds ratios (AOR) and confidence intervals (CIs) were calculated. Multivariate models were established to adjust for age, sex, BMI, hypertension, congestive heart failure, chronic obstructive pulmonary disease, smoking status, functional status, and ASA classification. A post-hoc power analysis was performed based on the observed variances between groups using an alpha equal to 0.05 and power equal to 0.8. Results: 86,023 patients undergoing knee arthroscopy and 58,442 patients undergoing shoulder arthroscopy were identified. Patients with IDDM undergoing knee arthroscopy were at a much higher risk for surgical complications, AOR 2.186 (95% CI: 1.226 -1.157, p = 0.001), including deep infections (AOR 3.082, 95% CI: 1.753-5.419, p < 0.001) and return to OR (AOR 1.933, 95% CI: 1.280-2.919, p = 0.002), as well as unplanned hospital admission (AOR 1.770, 95% CI: 1.289-2.431, p = 0.002). Patients with IDDM undergoing shoulder arthroscopy were at a much higher risk for medical complications (AOR 1.524, 95% CI: 1.082-2.147), hospital readmission (AOR 1.581, 95% CI: 1.153-2.169), and 30-day mortality (AOR 3.821, 95% CI: 1.243-11.750). However, NIDDM was not an independent risk factor for subsequent medical or surgical complications, unplanned hospital admission, or 30-day mortality in either group. Conclusion: Patients with IDDM undergoing knee arthroscopy were more likely to have surgical complications, whereas those undergoing shoulder arthroscopy were more likely to have medical complications, hospital readmission, and mortality. These risks diminished among those with NIDDM, with their risks comparable to those without diabetes. Physicians and hospitals should keep these issues in mind when counseling patients regarding their risks for shoulder and knee arthroscopy.

Purpose: To perform a systematic review with quantitative and qualitative analysis of publications to date focusing on the use of quadriceps tendon (QT) autografts in anterior cruciate ligament (ACL) reconstruction and to define the regional variability, type of publication, level of evidence, journal of publication, and type of QT graft used. Methods: The PubMed, Scopus, and Google Scholar databases were systematically queried for journal articles relating to QT autografts used for ACL reconstruction through 2018. These publications were filtered for relevance and then analyzed and differentiated by publication characteristics. Results: Most articles were published in the United States and Europe, and most articles evaluating clinical outcomes were Level of Evidence III. Over 60% of the publications (115 of 187) focusing on QT for ACL reconstruction were published within the past 10 years, and 30% (56 of 187) were published within the past 3 years. The results not only showed a recent increase in the number of publications regarding QT as a choice for the autograft harvest site in ACL reconstruction over time, but also yielded informative data regarding the publication journal, country or region, and level of evidence. Conclusions: This evaluation shows the increasing interest in the scientific evaluation of QT as a source of autograft tissue for ACL reconstruction. Clinical Relevance: Increased production of high-quality research will allow surgeons to feel more confident in their use of the QT as an autograft option in ACL reconstruction.
