Background:
- While intra-articular hip arthroscopy (e.g., labral repair, FAI correction) is well-established, extra-articular conditions are increasingly treated arthroscopically.
- Common extra-articular pathologies include:
- Greater trochanteric pain syndrome (GTPS)
- Internal snapping hip
- Anterior inferior iliac spine (AIIS) impingement
- Sciatic nerve entrapment
- Proximal hamstring injuries
Key Points:
- Current literature is limited, often case reports or small series.
- Extra-articular arthroscopic techniques are evolving and may offer less morbidity than open procedures, but long-term comparative data are lacking.
What Does This Mean for Providers?
- Consider arthroscopic options for extra-articular pathologies when conservative measures fail—particularly in athletic or active patients.
- While promising, these procedures should be considered within the context of limited evidence.
- Providers should counsel patients thoroughly on expected outcomes and current evidence limitations.
- Continued research and registry participation are essential for developing best practices.
