Review Meta Analysis
Diagnostic Accuracy of Imaging Modalities and Injection Techniques for the Diagnosis of Femoroacetabular Impingement/Labral Tear: A Systematic Review With Meta-analysis.
Diagnosing femoroacetabular impingement/acetabular labral tear (FAI/ALT) and subsequently making a decision regarding surgery are based primarily on diagnostic imaging and intra-articular hip joint injection techniques of unknown accuracy. ⋯ Although findings of the included studies suggested potentially favorable use of these modalities for the diagnosis of ALT and FAI, our results suggest that these findings have limited generalizability and clinical utility given very high pretest prevalence, large confidence intervals, and selection criteria of the studies. Registration: PROSPERO Registration #CRD42015027745.

Randomized Controlled Trial
Effectiveness of Radial Extracorporeal Shock Wave Therapy (rESWT) When Combined With Supervised Exercises in Patients With Subacromial Shoulder Pain: A Double-Masked, Randomized, Sham-Controlled Trial.
Subacromial shoulder pain is a common complaint, and radial extracorporeal shock wave therapy (rESWT) is increasingly used to treat this condition. Although many therapists use rESWT in combination with supervised exercises, no studies have evaluated the additional effect of rESWT with supervised exercises for subacromial shoulder pain. ⋯ Radial ESWT offered no additional benefit to supervised exercises in the treatment of subacromial shoulder pain after 24 weeks, except in the subgroup of patients with calcification in the rotator cuff. Registration: NCT01441830 ( ClinicalTrials.gov identifier).

Advancements in instrumentation and techniques have extended the scope of hip arthroscopic surgery to treat complex osseous deformities that were previously best addressed with an open approach. Global pincer-type femoroacetabular impingement is an example of an abnormality requiring osseous correction with a technically challenging access point. ⋯ Hip arthroscopic surgery for the management of symptomatic labral tears in patients with combined overcoverage and coxa profunda is associated with improvements in patient outcomes and pain at a minimum 2-year follow-up. However, the degree of improvement is of lower magnitude compared with a matched cohort with normal coverage undergoing the arthroscopic management of symptomatic labral tears. While hips with lateral overcoverage combined with coxa profunda may have a smaller potential for improvement compared with hips with normal coverage, this type of osseous morphology is still repairable with arthroscopic treatment.

Multicenter Study
Surgical Predictors of Clinical Outcomes After Revision Anterior Cruciate Ligament Reconstruction.
Revision anterior cruciate ligament (ACL) reconstruction has been documented to have worse outcomes compared with primary ACL reconstruction. ⋯ There are certain surgical variables that the physician can control at the time of revision ACL reconstruction that can modify clinical outcomes at 2 years. Whenever possible, opting for an anteromedial portal or transtibial surgical exposure, choosing a metal interference screw for femoral fixation, and not performing notchplasty are associated with significantly better 2-year clinical outcomes.

Comparative Study
Comparison of Clinical and Structural Outcomes by Subscapularis Tendon Status in Massive Rotator Cuff Tear.
The subscapularis tendon is essential in maintaining normal glenohumeral biomechanics. However, few studies have addressed the outcomes of tears extending to the subscapularis tendon in massive rotator cuff tears. ⋯ Arthroscopic repair of massive tears results in substantial improvements in shoulder function, despite the presence of combined subscapularis tears. However, this study showed a high failure rate of massive posterosuperior rotator cuff tear repair extending more than one-third of the subscapularis tendon. When combined subscapularis tendon tear was less than the superior one-third of the subscapularis tendon, arthroscopic debridement was a reasonable treatment method where comparable clinical and anatomic outcomes could be expected.
