Background
Heterotopic ossification (HO) is a known complication after hip arthroscopy. Its excision during revision surgery may help improve outcomes, but results are variable.
Methods
Retrospective review of 23 patients who underwent revision hip arthroscopy with arthroscopic HO excision. PROs (mHHS, NAHS, HOS-ADL, HOS-SS) and pain scores were collected pre- and post-operatively with minimum 1.5-year follow-up.
Key Findings
- All functional scores significantly improved post-excision.
- mHHS increased by over 20 points on average.
- Pain (VAS) decreased significantly.
- Despite improvements, few patients achieved “good” or “excellent” results.
Conclusions
Arthroscopic HO excision after failed hip arthroscopy can improve symptoms and function, though results are modest.
What this means for patients
- Patients with painful HO after initial surgery may benefit from revision.
- While improvement is likely, full symptom resolution is not guaranteed.
- Caution is warranted when considering revision surgery for HO.
