Outcomes following arthroscopic treatment for femoroacetabular impingement syndrome in patients with ossified labrum.

Abstract

To evaluate the results of arthroscopic treatment for femoroacetabular impingement syndrome (FAIS) with concomitant labrum ossification (LO) using patient-reported outcome measures (PROMs). The hypothesis was that at 2-year follow-up, an improvement in PROMs would be observed. A group of 24 patients (28 hips) with FAIS and LO findings were eligible for inclusion. In total 14 patients (18 hips) were included in the final PROMs analysis. The International Hip Outcome Tool short version (iHOT-12) was the primary outcome. The Copenhagen Hip and Groin Outcome Score (HAGOS), the European Quality of Life-5 Dimensions Questionnaire (EQ-5D), the EQ-visual analogue scale (EQ VAS), the Hip Sports Activity Scale for physical activity level, the VAS for overall hip function and a single question regarding overall satisfaction with the surgery were the secondary outcomes. At 2-year follow-up 6 out of 24 (25%) patients had undergone total hip arthroplasty (THA). Comparing PROMs preoperatively with 2-years follow-up for the group of patients that did not undergo THA (<i>n</i> = 14) showed statistically significant improvements (<i>P</i> < .05) for: iHOT-12 (39.3 versus 69.1), HAGOS subscales (symptoms 49.0 versus 70.9, pain 53.6 versus 80.0, sport 42.0 versus 68.5, daily activity 53.6 versus 73.2, physical activity 31.7 versus 61.5, quality of life 34.2 versus 65.0), EQ-5D (0.7 versus 0.8) and VAS for overall hip function (44.3 versus 66.5). Patients with FAIS and LO who had not undergone THA at 2-year follow-up following arthroscopic treatment showed improved outcomes regarding patient-reported outcomes. Level of evidence: Case series, level IV.
