Background
Generalized ligamentous laxity (GLL) is a condition where ligaments are looser than normal, potentially contributing to hip instability. This study examines how GLL affects patients undergoing hip arthroscopy and whether it influences their clinical outcomes.
Methods
The study included patients undergoing hip arthroscopy from February 2014 to November 2017. Patients were categorized based on their Beighton score, which assesses ligamentous laxity. Differences in clinical presentation, surgery findings, and treatment outcomes were compared.
Key Findings
Patients with higher Beighton scores (indicating more ligamentous laxity) were generally younger, had greater hip range of motion, and smaller labral tears. These patients were more likely to undergo procedures such as labral repair and iliopsoas fractional lengthening.
Conclusions
Patients with generalized ligamentous laxity are more likely to present with microinstability in the hip, which could require additional surgical interventions. They also tend to be younger and more female than those with less laxity.
What Does This Mean for Patients
If you have generalized ligamentous laxity, you may be more prone to hip instability and might require more complex treatments, such as labral repair or capsular procedures, during your hip arthroscopy. The outcomes are generally good, with improvements in function and pain relief.
