Background
Patients with coxa profunda and acetabular overcoverage (LCEA >40°) present technical challenges during hip arthroscopy, and outcomes in this population are less well defined.
Methods
Matched-pair study comparing 36 overcoverage patients to 36 controls with normal acetabular coverage (LCEA 25–40°). All underwent arthroscopy 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 rate of Seldes type 2 labral tears and THA conversion in the overcoverage group.
What Does This Mean for Providers?
- Arthroscopy is beneficial in overcoverage cases but produces more modest gains than in patients with normal morphology.
- Providers should anticipate technical challenges, higher-grade labral pathology, and an increased likelihood of arthroplasty conversion.
- Preoperative counseling should set realistic expectations and reinforce the role of anatomy in influencing outcomes.
