Background
Hip arthroscopy improves short-term outcomes in patients with FAIS and labral tears. However, long-term data in patients with acetabular overcoverage remain scarce.
Methods
Patients with FAIS, labral tears, and acetabular overcoverage were followed for at least 5 years after hip arthroscopy and compared to a matched cohort without overcoverage.
Key Findings
Both groups demonstrated significant and comparable improvements in hip function and patient-reported outcomes over 5 years. Notably, the acetabular overcoverage group had a significantly lower conversion rate to total hip arthroplasty (2.2% vs. 15.6%).
Conclusions
Hip arthroscopy provides durable functional improvements in patients with acetabular overcoverage, with a lower risk of progression to hip replacement compared to those without overcoverage.
What Does This Mean for Providers?
Providers can counsel patients with acetabular overcoverage that arthroscopic treatment yields sustained mid-term benefits and a lower likelihood of conversion to THA. This supports arthroscopy as a viable treatment even in this subset, guiding surgical decision-making and patient expectations.
