Purpose
To report minimum 2-year patient-reported outcomes (PROs) after hip arthroscopy (HA) for symptomatic labral tears in patients with global acetabular overcoverage.
Methods
Retrospective case series from April 2008 to April 2013 including patients with global acetabular overcoverage (lateral center-edge angle >40° and coxa profunda). Inclusion required minimum 2-year follow-up and no prior hip conditions or surgery. PROs recorded: modified Harris Hip Score (mHHS), Non-Arthritic Hip Score, Hip Outcome Score (HOS-ADL, HOS-SSS), visual analog scale (VAS), and patient satisfaction.
Key Findings
39 patients met criteria, 35 had 2-year follow-up. Significant improvement in all PROs, but mHHS, HOS-ADL, and HOS-SSS improvements did not reach minimal clinically important difference. Labral tears were mostly intrasubstance. Secondary procedure rate was 17%.
Conclusions
HA in global acetabular overcoverage improves PROs and pain at 2 years but with modest clinical significance. Labral injury pattern mainly intrasubstance damage with limited chondral injury.
What Does This Mean For Patients
Patients with global acetabular overcoverage may experience some improvement in hip symptoms after arthroscopic treatment, but the overall clinical benefit may be limited and some may need further surgery.
