Arthroscopic surgery in borderline dysplastic hips remains controversial, but the role of the ligamentum teres (LT) has not been studied in this setting. ⋯ In borderline dysplastic patients undergoing hip arthroscopic surgery with labral treatment and capsular plication, LT tears may indicate advanced instability and portend slightly inferior outcomes when compared with a match-controlled group. Borderline dysplastic patients with LT tears may have increased propensities toward revision arthroscopic surgery and conversion to THA. LT tears in these patients may warrant consideration for additional procedures including periacetabular osteotomy and LT reconstruction.

Review Meta Analysis
The Therapeutic Effect of Intra-articular Normal Saline Injections for Knee Osteoarthritis: A Meta-analysis of Evidence Level 1 Studies.
Intra-articular normal saline (IA-NS) injections have been utilized as a placebo in a number of randomized controlled trials pertaining to the management of knee osteoarthritis (OA); however, it is believed that these "placebo" injections may have a therapeutic effect that has not been quantified in the literature. ⋯ The administration of an IA-NS placebo injection yields a statistically and clinically meaningful improvement in PROs up to 6 months after the injection in patients with knee OA. This observation supports the notion that the so-called placebo effect for IA-NS injections achieves a clinically meaningful response in patients with OA when provided during comparison studies to an active treatment group (ie, hyaluronic acid).

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.

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.
