Summary

Patients who underwent iliopsoas fractional lengthening and hip arthroscopy demonstrated improvement in painful internal snapping and patient-reported outcomes at 10-year minimum follow-up.

Abstract

Purpose

To report minimum 10-year outcomes and the rate of painful snapping resolution for patients who underwent concomitant iliopsoas fractional lengthening (IFL) and hip arthroscopy. A propensity-matched analysis was used to compare IFL hips to those that did not undergo IFL during hip arthroscopy.

Methods

Data was prospectively collected and retrospectively reviewed for all patients who underwent hip arthroscopy as treatment for FAI and labral tears between 2008 and 2014. Patients who had IFL performed with hip arthroscopy and ten-year minimum follow-up were included in the study group. Patients were excluded from this study if they had previous ipsilateral hip surgical history, preoperative Tonnis osteoarthritis grade > 1, or workers compensation claims. PROs, rates of meeting clinically relevant thresholds, secondary procedures, and survivorship were compared between the IFL and the control groups.

Results

A total of 402 hips were included in the study, with 201 hips each group. The study group showed significant improvements in all PROs, with a 97.5% resolution rate of painful internal snapping. The IFL group had lower preoperative scores for NAHS and HOS-SSS (p < 0.05), but both groups had similar postoperative scores for all PROs (p > 0.05). Both groups met MCID and PASS for mHHS, NAHS, and HOS-SSS at similar rates (p > 0.05). Rates of revision surgery were similar between the groups (p >0.05), yet the IFL group had a lower rate of 10-year survivorship than the control group (OR 2.61, 95% CI [1.39 to 4.86], p < 0.01).

Conclusion

Patients who underwent IFL and hip arthroscopy demonstrated improvement in painful internal snapping and PROs at 10-year minimum follow-up. When compared to a control group of patients who did not undergo IFL, the groups had similar outcomes, but the IFL hips had lower survivorship rates.
