Abstract
PURPOSE: To understand the early outcomes after hip arthroscopy and better define the trajectory of improvement in a prospective cohort of patients who have undergone hip arthroscopic osteochondroplasty for femoroacetabular impingement (FAI) syndrome. METHODS: Data were analyzed from the Femoroacetabular Impingement RandomiSed controlled Trial (FIRST) on the 108 study patients who underwent osteochondroplasty, with or without labral repair. Study outcomes included patient-reported pain (using a 100-point Visual Analogue Scale (VAS)), hip function (using the Hip Outcome Score (HOS) and International Hip Outcome Tool (iHOT-12)), and health-related quality of life (using the EuroQol 5 Dimensions (EQ-5D)) measured at baseline, 2 weeks, 3 months, 6 months, and 12 months post-operatively. RESULTS: There was a decrease in mean post-operative pain VAS scores from baseline. The first 2 weeks post-operative yielded the greatest reduction in pain with a mean (SD) VAS score of 37.8 (23.4), with score stabilization between 6 months (26.9 (26.9)) and 12 months (25.3 (27.6)). Mean HOS (activities of daily living) scores improved from baseline (59.7 (16.2)) starting at 6 weeks post-operative (64.1 (19.1)). The HOS (Sports) showed no improvement from baseline (41.2 (20.4)) until 3 months (49.1 (27.9)), and continued to improve at 6 months (64.1 (28.7)) and 12 months (68.6 (30.5)). The iHOT-12 scores showed functional improvement from baseline (31.3 (18.8)), as early as 6 weeks (44.9 (22.4)) up to and including 12 months (67.1 (29.7)). EQ-5D index scores showed modest steady improvement from 6 weeks to 12 months post-operative, while the EQ-5D VAS component similarly showed modest and steady improvements from 3 months onward. CONCLUSION: Results from this study highlight that hip arthroscopic osteochondroplasty with or without labral repair for FAI leads to early pain relief. While all scores improved from baseline, functional gains appear to plateau from 6 months onwards. These data can be used to inform decision-making about timelines for rehabilitation and return to sport, a knowledge gap in the current FAI literature. LEVEL OF EVIDENCE: II.
