Background
Generalized ligamentous laxity (GLL), often assessed with the Beighton score, is associated with microinstability and may impact surgical planning in hip arthroscopy.
Methods
167 patients were stratified based on Beighton scores (≥4 = GLL). Demographics, intraoperative findings, and treatment approaches were compared across groups.
Key Findings
- GLL patients were younger (average age ~28), more likely to be female, had increased hip ROM, and exhibited smaller labral tears.
- GLL patients more often required procedures addressing instability, such as capsular plication and IFL.
What Does This Mean for Providers?
- Screen for GLL using Beighton scoring preoperatively. These patients often have subtle microinstability requiring tailored surgical strategies (e.g., capsular closure or plication).
- GLL can guide intraoperative decision-making, especially regarding preservation vs reconstruction and addressing dynamic instability components.
- Long-term outcomes remain favorable when surgical plans are adjusted for GLL-related biomechanical factors.
