Postoperative hip bracing reduces kinesiophobia in patients undergoing hip arthroscopy: a randomized-controlled trial.

INTRODUCTION

Detailed postoperative rehabilitation protocols after hip arthroscopy for femoroacetabular impingement syndrome (FAIS) are still a matter of debate. Adjunctive hip bracing represents a promising tool to improve early patients' mobilization. To present, the effect of hip brace therapy on postoperative functional outcomes and specific patient individual psychologic factors remains controversially discussed. Consequently, we aimed to report postoperative outcomes focusing on hip function, pain and kinesiophobia between braced and unbraced patients.

MATERIALS AND

METHODS

A prospective, randomized-controlled trial was conducted, including patients undergoing hip arthroscopy for FAIS. After exclusion, a final study cohort of 36 patients in the intervention group (postoperative hip brace) and 36 patients in the control group (no hip brace) were compared for kinesiophobia (Tampa Scale of Kinesiophobia), pain (Visual analog scale) and joint function (International Hip Outcome Tool-12) within the first six postoperative months.

RESULTS

Hip arthroscopy significantly improved all patient-reported outcomes in both groups. Intergroup analysis revealed significantly lower levels of kinesiophobia in braced patients at 6-months follow up (30.7 vs. 34.1, p = 0.04) while not negatively affecting pain and joint function. No intra- and postoperative complications occurred within both groups.

CONCLUSIONS

This study could demonstrate that bracing after hip arthroscopy can positively influence kinesiophobia, while the brace did not negatively impact postoperative pain and quality of life. Thus, hip bracing could be a viable assistive therapy in the postoperative rehabilitation phase after hip arthroscopy.
