Purpose
To determine if acetabular labral size correlates with the degree of hip dysplasia measured radiographically.
Methods
- Prospective study of 130 patients undergoing hip arthroscopy.
- Arthroscopic measurement of labral size in 4 acetabular quadrants.
- Patients subdivided by radiographic dysplasia parameters (LCEA, AI, ACEA).
Key Findings
- Dysplastic hips (LCEA ≤25°) had significantly larger labra in all quadrants.
- AI >10° related to larger posteroinferior labrum.
- ACEA ≤20° linked to larger anteroinferior and posteroinferior labra.
Conclusion
Labral hypertrophy is present in dysplastic hips, likely compensating for reduced bony coverage.
What This Means for Patients
If you have hip dysplasia, your labrum may enlarge to compensate for less bone coverage, which could influence surgical decisions about labral repair or reconstruction.
