Acute and Subacute Changes in Hip Strength and Range of Movement After Arthroscopy to Address Chondrolabral Pathology

Abstract

Background: Hip pain is associated with reduced muscle strength, range of movement (ROM), and function. Hip arthroscopy is undertaken to address coexistent intra-articular pathologies with the aim of reducing pain and improving function. Purpose: To evaluate changes in strength and ROM in a cohort with chondrolabral pathology before surgery to 3 and 6 months after hip arthroscopy. Study Design: Case series; Level of evidence, 4. Methods: Sixty-seven individuals with hip pain who were scheduled for hip arthroscopy were matched with 67 healthy controls. Hip strength and ROM were collected preoperatively and at 3 and 6 months postoperatively. Repeated measures analysis of variance evaluated whether strength and ROM differed between limbs and among time points. Bonferroni post hoc tests determined differences in hip strength and ROM among testing times and between the hip pain group and matched controls. Results: Hip extension, internal rotation (IR), external rotation (ER), and adduction (P
