Arthroscopic Iliopsoas Fractional Lengthening for Internal Snapping of the Hip: Clinical Outcomes With a Minimum 2-Year Follow-up
Authors: El Bitar YF, Stake CE, Dunne KF, Botser IB, Domb BG
Purpose:
To evaluate outcomes of arthroscopic iliopsoas (IP) tendon fractional lengthening in patients with internal snapping hip.
Methods:
Prospective case series of 55 patients undergoing arthroscopic IP fractional lengthening with minimum 2-year follow-up. Patient-reported outcomes (NAHS, HOS-ADL, HOS-SSS, mHHS), pain (VAS), and satisfaction were assessed.
Key Findings:
- Significant improvement in all patient-reported outcomes (P < .001).
- 82% reported resolution of painful snapping and good/excellent satisfaction.
- Patients with snapping resolution had better overall outcome improvements than those with persistent snapping.
Conclusion:
Arthroscopic IP fractional lengthening effectively treats painful internal snapping hip, though some patients may have persistent symptoms.
What Does This Mean for Providers?
- This minimally invasive procedure should be considered for patients with symptomatic internal snapping not responsive to conservative treatment.
- Patient counseling should include the possibility of persistent snapping in a minority of cases.
- Improved functional outcomes and patient satisfaction support its use as part of hip arthroscopy procedures.
