Background: Outcomes for patients with femoroacetabular impingement (FAI) treated with hip arthroscopy can differ depending on whether there is underlying intra-articular pathology.

Purpose: To evaluate the outcomes of patients after undergoing hip arthroscopy depending on their underlying pathology (isolated FAI, isolated labral tear, or combined FAI and a labral tear) using the 12-Item International Hip Outcome Tool (iHOT-12).

Study Design: Cohort study; Level of evidence, 3.

Methods: A total of 75 patients diagnosed with FAI with or without labral tears and isolated labral tears who underwent hip arthroscopy performed by the same surgeon at a single institution from January 2014 to December 2019 were included in this study. All patients had at least 2 years of follow-up data. Patients were divided into 3 groups as follows: patients with FAI and an intact labrum; patients with an isolated labral tear; and patients with combined FAI and a labral tear. The iHOT-12 scores at 1.5, 3, 6, 12, 18, and >24 months postoperatively were compared and analyzed. Outcome scores were also evaluated in terms of the substantial clinical benefit (SCB) and the patient-acceptable symptomatic state (PASS).

Results: Of 75 patients who underwent hip arthroscopy, 14 had FAI, 23 had labral tears, and 38 had both. All groups showed significant improvements on the iHOT-12 from preoperative to the final follow-up (FAI, from 37.64 ± 3.77 to 93.64 ± 1.50; labral tear, from 33.70 ± 3.55 to 93 ± 1.24; combined, from 28.55 ± 3.15 to 93.03 ± 0.88) ( < .001 for all). However, compared with other groups, the patients with FAI and a labral tear had lower scores at 1.5, 3, 6, and 12 months postoperatively ( < .001), highlighting a slower rate of recovery. For all groups, recovery to normal function according to the SCB was 100% at 12 months, and satisfaction according to the PASS was 100% at 18 months postoperatively.

Conclusion: The final iHOT-12 scores were similar at 18 months regardless of the pathology treated; however, patients with FAI and a labral tear took longer to reach their plateau.

Background: Inconsistencies in the workup of labral tears in the hip have been shown to result in a delay in treatment and an increased cost to the medical system.

Purpose: To establish consensus statements among Canadian nonoperative/operative sports medicine physicians via a modified Delphi process on the diagnosis, nonoperative and operative management, and rehabilitation and return to play (RTP) of those with labral tears in the hip.

Study Design: A consensus statement.

Background: While glenoid bone loss (GBL) after anterior shoulder instability correlates with poor functional outcomes, the specific effects of GBL in posterior and combined-type shoulder instability remain poorly characterized, especially in a high-risk military population.

Purpose/hypothesis: The purpose of this study was to compare GBL between unidirectional anterior or posterior instability versus combined-type instability in active-duty servicemembers. It was hypothesized that total GBL and GBL in the direction of instability would be greater in those with combined-type instability compared with unidirectional instability.

Intraoperative assessment of labral quality determines arthroscopic repair versus reconstruction for hip labral tear treatment. T2 mapping technology discriminates between healthy and damaged cartilage. This study investigated if T2 mapping magnetic resonance imaging (MRI) can preoperatively predict labral repair versus reconstruction.
