Background
- Sex differences are commonly seen in orthopaedic conditions. For hip pathology, males are more likely to have cam-type femoroacetabular impingement (FAI), while females are more likely to experience hip instability.
- This study explores how sex, hip morphology, and generalized ligamentous laxity (GLL) affect hip pathologies in patients with non-arthritic hips undergoing arthroscopy.
Methods
- The study analyzed patients who underwent primary hip arthroscopy for femoroacetabular impingement syndrome (FAIS) and labral tears between 2008 and 2017.
- Patients were divided into male and female groups and subanalyses were conducted based on alpha angle (for men) and GLL (for women).
Key Findings
- Males had larger alpha angles and more severe acetabular cartilage damage compared to females.
- In women, GLL was more prevalent (38.6% vs. 13.6%), and those with GLL had a lower lateral center-edge angle.
- Larger cam-type anatomy in males was associated with more severe acetabular damage.
Conclusions
- Men tend to have more severe acetabular damage linked to cam-type impingement, while women are more likely to have hip instability features like GLL.
What Does This Mean for Patients
- If you're a male with a larger alpha angle or a female with generalized ligamentous laxity, your hip may experience more severe damage. Tailored treatment can help address these specific issues.
