Summary
A rare hip dislocation occurred 5 months after hip arthroscopy in an athlete. This suggests routine capsular closure and avoiding psoas release in anteverted hips may prevent such complications.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Biomechanical Engineering
Background:
- Hip arthroscopy is a common procedure for treating hip labral tears and femoroacetabular impingement (FAI).
- Complications, though rare, can significantly impact patient outcomes, especially in athletes.
- Anterior hip dislocation is an uncommon postoperative complication following hip arthroscopy.
Observation:
- A case of low-energy anterior hip dislocation is presented, occurring 5 months post-arthroscopy.
- The patient was a track and field athlete treated for a labral tear and cam lesion.
- Dislocation occurred during competitive jumping, involving significant hip flexion and extension.
Findings:
- Failure to close the hip capsule during arthroscopy is the likely cause of the delayed dislocation.
- A partial psoas release may have contributed to dynamic hip instability due to increased femoral anteversion.
- The extended delay (5 months) is longer than previously reported for this complication.
Implications:
- Routine hip capsule closure should be considered in all hip arthroscopy procedures.
- Psoas release should be avoided in patients with significant femoral anteversion to prevent dynamic instability.
- Athletes engaged in activities like competitive jumping may require more conservative return-to-sport protocols after hip arthroscopy due to biomechanical risks.
