Infection is an uncommon side effect of arthroscopic surgery, and this percentage is higher in anterior cruciate ligament reconstruction (ACLR) surgery, where graft and fixation devices are used. Infections can not only lead to high re-admission rates and poor functional recovery of the knee but can also have a significant negative impact on the patient’s psychological and economic health, especially in athletes, as it can affect their sports career. It is important to be aware of the many risk factors, especially the manifestation of symptoms. These may sometimes be non-specific to the infectious pathology and common to other situations, such as the presence of a significant intra-articular hematoma. Septic arthritis after ACLR can occur at any time after surgery but typically presents acutely, while late manifestation is relatively rare. Diagnosis of infection is based on patient history, physical examination, laboratory parameters, and analysis of synovial fluid after joint aspiration, which is the gold standard for diagnosing post-operative infection. Once symptoms appear and the diagnosis seems certain, it is necessary to intervene quickly with arthroscopic debridement and long-term antibiotic treatment to try to save the graft and resolve the infectious situation to avoid graft failure and arthrofibrotic sequelae. The aim of this paper is to provide an overview of the epidemiology, pathogenesis, risk factors, clinical presentation, diagnostic evaluation, and current treatment guidelines of septic arthritis after ACLR surgery by analyzing recent literature, in particular meta-analyses and systematic reviews.

BACKGROUND AND AIM:Supracondylar humeral fractures are the most common skeletal injury of childhood elbow. Treatment option for Gartland type II-III-IV fractures is based on closed reduction and percutaneous pinning (CRPP) fixation using Kirshner wires. Seldom open reduction is needed. Literature described different method of CRPP. The aim of the study is to report our experience in the surgical management of supracondylar humeral fractures comparing it with the literature, in order to identify useful information for a correct and better approach to reduce complications and improve clinical outcomes.METHODS:148 patients with a mean age of 5.72 ± 2.52 years and with Gartland type II-III-IV humeral supracondylar fractures were treated with CRPP at our Orthopedic Pediatric Unit. They were divided into three groups according to surgical technique. Group A was represented by patients treated with cross pinning (1 medial and 1 lateral pin), Group B represented by 2 lateral pins while Group C represented by 2 lateral and one medial pin. Evaluation criteria are based on Mayo Elbow Performance Index (MEPI); Bauman's and Carrying Angle and Flynn's criteria. Data were recorded at the following times: T0 (before surgical procedure); T1 (one-month post-surgery); T2 (six months post-surgery).RESULTS:The three surgical techniques showed comparable results according to MEPI, Bauman's angle, Carrying's angle and Flynn's criteria from T0 to T1. There is an improvement for all Groups. Group C reported the best MEPI outcome at T2. However, 2 patients in this group did not show excellent results according to Flynn's criteria.CONCLUSIONS:There is no single and superior treatment for displaced humeral supracondylar fractures and that each fracture has its own personality.

The COVID-19 pandemic drastically changed many aspects of the traditional functioning of health systems all around the world. In Italy, as reported by the CIO, compared to the previous year, there was a significant reduction in 2020 in overall outpatient activities by up to 75%. These data support the need for telemedicine, which represents a current challenge and can no longer be postponed in the future. This study aims to elaborate on a possible model for remote shoulder examination based on traditional tests to improve the quality of telemedicine in orthopedic and rehabilitation. Between May 2020 and November 2020, ten orthopedic surgeons individually examined six patients with a known shoulder disorder, both in hospital and via webcam according to the previously shared protocol (B-STEP). According to the 10 observers, completing 100% of the ASES score and at least 87.5% of the Constant score is possible. Shoulder ROM and many specific tests are also reproducible via webcam, but with less sensitivity, according to the subjective opinion of observers. The B-STEP is a useful protocol for the standardization of the objective examination of the shoulder via webcam. Further studies are necessary to determine if the B-STEP protocol is useful for diagnosing pathology in unknown patients and evaluating its sensitivity and specificity for each pathology.

Background: Rotator cuff tendinopathy is a common diagnosis among patients with shoulder pain and dysfunction. Laser therapy is recommended for the treatment of this tendon disease due to the possibility of increasing tissue biostimulation. The aim of this study was to investigate the effects of HELT (high-energy laser therapy) in relation to the wavelengths of 650 nm, 810 nm, 980 nm, and 1064 nm administered. Methods: The study design was prospective and observational. Thirty patients with shoulder tendinopathy were recruited and treated in one of two high-energy laser therapy groups (5 Watt/cm2, 450 Joule, super-pulsed mode). Group A received a high-energy laser therapy protocol with a single wavelength (1064 nm); group B received a high-energy laser therapy program with four wavelengths (650 nm, 810 nm, 980 nm, and 1064 nm). Pain (VAS), function (ASES), and disability (DASH) were monitored at the time of recruitment (T0), 1 month later (T1), and 6 months later (T2). Roles and Maudsley scores were also evaluated at T1 and T2. Results: Both protocols resulted in improvement of pain and in functional and disability recovery at the two times of assessment, without statistically significant differences. In group B, treated with the four wavelengths, a trend emerged, bordering on statistical significance, for a greater reduction in pain. Conclusions: The high-energy laser proved to be an effective therapy for the treatment of rotator cuff tendinopathy. The possibility of modulating the choice of wavelengths could allow the customization of the protocol in relation to the patient’s clinical condition.

Total hip arthroplasty (THA) is a common surgical procedure used to treat hip osteoarthritis and other joint conditions that cause pain and functional limitation. Traditionally, THA has been performed most often in elderly patients, but in recent years, there has been an increase in hip arthroplasties in young patients. Femoral prosthesis rupture is a rare but significant complication that can also occur in young patients undergoing total hip arthroplasty (THA). Some of the factors that can contribute to femoral prosthesis ruptures include abnormal overload, defects in the design, lack of geometric fit, and type of materials used in the stem and femoral head connection. The aim of this study is to analyze the criticalities in the contact between the femoral head and the stem neck. In particular, two types of contacts will be taken into consideration: proximal and distal, and through the finite element method (FEA), the criticalities will be defined. The results show that in the proximal contact, the stress levels exceeded 500 MPa in certain areas of the prosthesis. This stress could potentially lead to structural failure, such as rupture or deformation of the prosthesis. In addition, to prevent bacterial infiltration or debris from the outside, the distal connection is recommended.

Background: Performing meniscal repair with anterior cruciate ligament reconstruction (ACLR) has been shown to contribute to the long-term preservation of knee health and gait biomechanics. Purpose: To evaluate the role of meniscal repair in the performance of semiprofessional soccer players who returned to sport after ACLR. Study Design: Case series; Level of evidence, 4. Methods: This study included 51 male soccer players (mean ± SD age, 28.82 ± 5.33 years) who underwent ACLR at a single institution between July 2018 and July 2019. The players were divided into 3 groups according to surgery type: ACLR only (n = 30), ACLR with lateral meniscal repair (n = 9), and ACLR with medial meniscal repair (n = 12). Outcomes were evaluated through clinical examination, self-reported health questionnaires (Cincinnati Knee Rating System, Tegner activity score, Tegner Lysholm Knee Scoring Scale, Tampa Scale of Kinesiophobia, and ACL–Return to Sport After Injury), and biomechanical performance evaluations (balance, strength, coordination, and symmetry tests). Parametric and nonparametric tests were carried out for multiple comparisons. Results: The mean ± SD follow-up time was 20.75 ± 9.38 months. Although no significant differences emerged in clinical and self-reported health status, almost all the physical parameters tested resulted in lower performance in players treated with ACLR and meniscal repair. Moreover, patients with ACLR with lateral meniscal repair reported higher pain and fear of reinjury, with lower outcomes in terms of strength, symmetry, and coordination as compared with the other 2 groups. Balance abilities were significantly affected in players who underwent meniscal repair as compared with those who underwent ACLR only. Conclusion: The findings showed that biomechanical performance measures and fear of reinjury were significantly worse in soccer players with associated meniscal repair at a minimum 1-year follow-up, especially in those with a lateral meniscal tear.

The knee is one of the most frequently affected joints in sports trauma, and anterior cruciate ligament (ACL) injury and meniscal tears are the most common lesions. ACL reconstruction (ACLR) remains the treatment of choice for patients willing to return to their previous activity. There are different surgical techniques and different possible usable grafts. The graft used for ACLR surgery undergoes a bone incorporation process and an intra-articular remodelling named ligamentization until it reaches characteristics similar to the native ligament. After the first incorporation stage, the remodelling process is divided into an early stage that could last 4 weeks, a proliferative stage that lasts 4 to 12 weeks, and a final stage of ligamentization that could last over 1 year. The period of return to sport (RTS) after ACLR, which is becoming shorter and shorter, can be a high-risk period for athletes due to the risk of graft failure. This systematic review aims to define the phases of the ligamentization process considering graft type and fixation techniques, as well as the graft's anatomopathological and biomechanical characteristics, to evaluate a criterion-based rehab progression and maximize patient outcomes for an RTS respecting graft biology. The rehabilitative program has to promote and optimize the graft remodelling and incorporation processes; moreover, it has to accommodate physiological graft healing and avoid overloading. An early RTS and noncompliance with the biological characteristics of the graft in the various phases are associated with a high incidence of re-injury.

Osteoarthritis (OA) is the most prevalent degenerative joint disease and the main cause of pain and disability in elderly people. OA currently represents a significant social health problem, since it affects 250 million individuals worldwide, mainly adults aged over 65. Although OA is a multifactorial disease, depending on both genetic and environmental factors, it is reported that joint degeneration has a higher prevalence in former athletes. Repetitive impact and loading, joint overuse and recurrent injuries followed by a rapid return to the sport might explain athletes’ predisposition to joint articular degeneration. In recent years, however, big efforts have been made to improve the prevention and management of sports injuries and to speed up the athletes’ return-to-sport. Biophysics is the study of biological processes and systems using physics-based methods or based on physical principles. Clinical biophysics has recently evolved as a medical branch that investigates the relationship between the human body and non-ionizing physical energy. A physical stimulus triggers a biological response by regulating specific intracellular pathways, thus acting as a drug. Preclinical and clinical trials have shown positive effects of biophysical stimulation on articular cartilage, subchondral bone and synovia. This review aims to assess the role of pulsed electromagnetic fields (PEMFs) and extracorporeal shockwave therapy (ESWT) in the prevention and treatment of joint degeneration in athletes.

The purpose of this meta-analysis is to evaluate the efficacy of plate or external fixator treatments in distal radius fractures, based not only on clinical and radiographic parameters but on Health Related Quality of Life (HRQOL) parameters. The Preferred Reporting Items for Systematic Reviews and Metanalyses (PRISMA) guidelines were followed when conducting this systematic review. The Revised Assessment of Multiple Systematic Reviews (RAMSTAR) checklist was additionally consulted in order to ensure a high-quality methodological process, encompassing such elements as an ‘a priori’ design, independent reviews and comprehensive search. The literature search was carried out on PubMed, MEDLINE and Scopus. The search terms used were “Radius fracture AND osteosynthesis”, “Wrist fracture AND external fixator” and “Wrist fracture AND plate”. Two reviewers independently screened titles, abstracts and full texts. To determine inter-reviewer agreement, a k score was calculated after each screening state. Of the 5753 studies collected through the initial databases search, two studies were included in the final meta-analysis (125 treated with external fixator vs 132 with volar plate). There was a substantial inter-reviewer agreement as to the title (0.73; 95% confidence interval, 0.67-0.79) abstract (0.65; 95% CI, 0.46-0.83) and fulltext screening stages (0.89; 95%CI, 0.67-1). The meta-analysis reported a mean difference equal to 0.00 (95%CI= -0.05 – 0.05), in accordance with I2= 0% and p test for the heterogeneity value=0.089. This meta analysis confirms and quantifies that the two techniques are superimposable as regards the quality of life reported by patients at least one year of follow-up.

Calcaneal fractures are a challenging clinical problem. Management of this type of injury remains controversial, especially in the context of intra-articular fractures. Surgical treatment with open reduction and internal synthesis (ORIF) is considered the standard treatment for CF, but it is associated with many complications. Several minimally invasive techniques such as balloon-assisted reduction, pin fixation, and tricalcium phosphate augmentation have been proposed to avoid the frequent and recurrent postoperative problems related to these fractures. We retrospectively examined 20 patients (mean age was 54.5), all undergoing minimally invasive calcaneoplasty surgery at our Department of Orthopaedics and Traumatology between 2012 and 2016. X-ray and CT scan were performed preoperatively and at 5 years of follow-up (57.9 ± 6 months). The American Orthopaedic Foot and Ankle Society (AOFAS) score was used for clinical examination, and the Short-Form (36) Health Survey (SF-36) score and Visual Analogue Scale (VAS) were used to assess the Health-Related Quality of Life (HRQoL). All 20 patients were available at the final follow-up. The mean AOFAS score was 82.25/100. The VAS results attest an overall average of 2.7/10 (0–9). The average of the parameters “Physical Health” and “Mental Health” was, respectively, 81.25 and 83.55. In terms of postoperative complications, we observed no cases of superficial or deep infections. Clinical response after balloon-assisted reduction, pin fixation, and tricalcium phosphate augmentation has shown a comparable or better outcome according to the AOFAS and VAS score. Quality-of-life scores, obtained according to the SF-36 questionnaire, are considered high. From both a clinical and quality-of-life point of view, our study highlights that there is not gender distinction. Further comparative studies with a higher number of patients are needed which assess the quality of life in the various techniques used to treat calcaneal fractures.
