Return to Sport at Preinjury Level is Common After Surgical Treatment of SLAP Lesions: A Systematic Review and a Meta-analysis.

BACKGROUND: Patients undergoing surgery for Superior-Labrum-anterior-to-posterior (SLAP) lesions are often worried about their return to sport performance. This systematic review determined the rate of return to sport and return to sport at the previous level (RTSP) after surgery for SLAP lesion. MATERIALS AND METHODS: The PRISMA guidelines were followed. Meta-analysis of data through forest plot projections was conducted. Studies were divided and analyzed according to the type of interventions (isolated slap repair or SLAP repair with rotator cuff debridement and biceps tenodesis). RESULTS: The mean overall rate of return to sport after the procedures was 90.6% and the mean overall rate of return to sport at the previous level after the procedures was 71.7%. RTSP rates of the whole population were 71% (95% CI: 60%-80%), 66% (95% CI: 49%-79%), and 78% (95% CI: 67%-87%) for isolated SLAP repair, SLAP repair with the rotator cuff debridement and biceps tenodesis, respectively. A lack of subgroup analysis for the specific performance demand or type of lesion related to the surgical technique used might induce a high risk of bias. DISCUSSION: Return to sports at the previous level after surgically treated superior labrum anterior to posterior lesion is possible and highly frequent, with the highest rates of RTSP in patients treated with biceps tenodesis. More studies and better-designed trials are needed to enrich the evidence on indications of SLAP surgical treatment in relation to specific sports-level demand. LEVEL OF EVIDENCE: Level-IV.

Magnetic Resonance Imaging in the Evaluation of Avulsion Injuries of the Pelvis and Hip in Adolescent Professional Footballers: A Case Series.

Introduction: Pelvic apophyseal avulsion fractures are uncommon injuries that frequently affect adolescents while participating in sports. This occurs because the enthesis cannot withstand the tractional force applied because the apophysis has not yet fully fused. Due to its complex muscular structure, being the origin of several muscles that cross two lower extremity joints, the pelvis has an increased risk for such injuries. The diagnosis of pelvic avulsion injuries depends heavily on imaging. The best way to detect soft-tissue changes, including tendon or muscle strain, bone marrow edema, hematomas, and soft tissue avulsion injuries, is with an magnetic resonance imaging . It is also the best at showing tendon retraction and can help the clinician spot patients who might benefit from surgical treatment. Case Report: We report six cases of adolescents professional footballers that suffered avulsion injuries while playing football. The patients had painfully restricted hip range of motion and were unable to bear weight. Some of them on physical examination felt pain at the palpation of the injured area. Magnetic resonance revealed apophysis growth plate avulsion with or without displaced bone fragments that were treated conservatively with an excellent clinical and radiological outcome. Conclusion: For an accurate diagnosis of pelvic avulsion injuries and clinical management, it is important that everyone caring for this patient population is aware of the common injury mechanisms, radiographic findings, and available treatments.

Dual-mobility total hip arthroplasty in patients younger than 55 years old: a systematic review.

Total hip arthroplasty (THA) is regarded as one of the most successful and cost-effective orthopedic procedures. However, THA is a surgical procedure with potential intraoperative and postoperative risks. Dislocation is one of the common postoperative complications and remains one of the main indications for THA revision. The purpose of this systematic review was to evaluate the role and the outcomes of dual-mobility implant to prevent dislocation in patients younger than < 55 years in primary THA. In this systematic review, we included observational, prospective, and retrospective studies that evaluated the outcome and the complications of the dual-mobility cup in < 55-year-old patients. After applying exclusion criteria (femoral neck fractures or THA revision, case series, reviews, and meta-analyses), ten articles were included in the study. The overall number of participants in all the studies was 1530. The mean age of the participants was 50 years. The mean follow-up was 11.7 years. A total of 46 patients (2.7%) reported intraprosthetic dislocations, in which the polyethylene liner dissociates from the femoral head, while 4.8% of revision was due to aseptic loosening. The mean revision rate at twelve years was 11%. The mean value of Harris Hip Score increased from 50.9 pre-operatively to 91.6 after surgery. Dual mobility is a valid option for young patients with extended survivorship and low rates of instability and dislocation after primary THA.

No clinical differences at the 2-year follow-up between single radius and J-curve medial pivot total knee arthroplasty in the treatment of neutral or varus knees.

PURPOSE: Modern total knee arthroplasty (TKA) systems are designed to reproduce the normal knee kinematics and improve patient outcome. The authors compared two different third-generation medial pivot TKA implants, having a single-radius or a J-curve design in their sagittal plane, hypothesizing no clinical differences. METHODS: Two cohorts of 50 patients who underwent primary TKA were first preoperatively matched by sex, deformity, body mass index (BMI), Oxford Knee Score (OKS), Knee society score (KSS) and range of motion (ROM) and then statistically analyzed at a minimum follow-up (FU) of 2 years. An identical surgical technique, which aimed to reproduce a slightly tighter medial than lateral compartment, was used in all knees. RESULTS: At a minimum follow-up of 2 years (range 24-34 months) there were no statistically significant differences in OKS and KSS between the two implant groups. The final ROM differed statistically between the two groups: the average maximum active flexion was 123° in the J-curve femoral design group with an adapted "medially-congruent" polyethylene insert, and 116° in the single radius femoral design with a medial "ball-in-socket" articulation. CONCLUSION: No clinical and radiological differences were found when the two cohorts of patients were compared. This study showed that the implant design played a minor role in the final outcome as opposed to a precise surgical technique. LEVEL OF EVIDENCE: Retrospective case-control study, Level III.
