Background
Patients with acetabular overcoverage and coxa profunda present a technical challenge during hip arthroscopy. The study compares outcomes of these patients to matched controls with normal acetabular coverage.
Methods
Matched-pair cohort study of 36 patients with LCEA >40° and profunda acetabulae vs. 36 controls with LCEA 25–40°, all treated arthroscopically for labral tears with minimum 2-year follow-up.
Key Findings
- Both groups improved significantly in PROs and pain.
- Overcoverage group had less improvement in mHHS (13.5 vs. 21.7; p = .032) and lower satisfaction (6.6 vs. 7.9; p = .019).
- Higher incidence of Seldes type 2 labral tears and conversion to THA in overcoverage group.
Conclusions
Arthroscopy can benefit patients with acetabular overcoverage, but outcomes are not as strong as in those with normal acetabular morphology.
What This Means for Patients
- Surgery may help, but patients with acetabular overcoverage may see less improvement and are more likely to need hip replacement.
- Anatomic variations like coxa profunda may limit full recovery.
- Thorough pre-op counseling is important.
