Background:
Assesses outcomes of arthroscopic iliopsoas fractional lengthening and capsular plication in patients with iliopsoas snapping and acetabular dysplasia (LCEA < 25°).
Methods:
Patients underwent arthroscopic iliopsoas lengthening and capsular plication. PROs, pain scores, satisfaction, and radiographic osteoarthritis progression were tracked.
Key Findings:
- Significant improvement in PROs and pain scores.
- High patient satisfaction (mean 8.0/10).
- Minimal radiographic progression of osteoarthritis.
- Low revision rate for labral retears (4 patients).
Conclusions:
Arthroscopic management of iliopsoas snapping with fractional lengthening and capsular plication in dysplastic hips offers pain relief and functional improvement without accelerating osteoarthritis.
What Does This Mean for Providers?
Providers managing acetabular dysplasia patients with symptomatic iliopsoas snapping should consider arthroscopic fractional lengthening combined with capsular plication. This approach can improve outcomes while preserving joint integrity and limiting OA progression, but careful radiographic and clinical evaluation is essential.
