Abstract
PurposeThe purpose of the present study was to evaluate the outcome of arthroscopic treatment for femoroacetabular impingement (FAI) syndrome 5 years post-surgery using patient-reported outcome scores (PROMs) validated for a young and active population with hip complaints.MethodsPatients were prospectively included in the study. A total of 184 patients [males = 110 (59.8%), females = 74 (40.2%)], with mean age 38.0, underwent arthroscopic treatment for FAI syndrome and were analysed. Preoperatively and at the 5-year follow-up, patients completed a set of self-administered web-based PROMs consisting of the International Hip Outcome Tool (iHOT-12), the Copenhagen Hip and Groin Outcome Score (HAGOS), the Hip Sports Activity Scale (HSAS), the EuroQoL-5 Dimension Questionnaire (EQ-5D), the EQ-Visual Analogue Scale (VAS) and the VAS for overall hip function and overall satisfaction. The Wilcoxon signed rank test was used to compare preoperative PROM values with those obtained at the 5-year follow-up.ResultsA comparison of preoperative PROM scores and those obtained at the 5-year follow-up revealed statistically significant improvements for all outcome scores (p < 0.05), except for the HSAS score, which were unchanged; iHOT-12 (42.9 vs 67.2), HAGOS different subscales (50.2 vs 69.6, 55.7 vs 76.1, 59.2 vs 72.3, 41.1 vs 66.4, 30.8 vs 60.2, 31.6 vs 60.4), EQ-5D (0.570 vs 0.742), EQ-VAS (66.6 vs 74.4), HSAS (3.13 vs 3.17) and VAS for overall hip function (47.9 vs 69.2). At the 5-year follow-up, 154 patients reported that they were satisfied with surgery (84.6%). Survivorship at the 5-year follow-up was 86.4%.ConclusionArthroscopic treatment for FAI syndrome yields good patient-reported outcome at the 5-year follow-up.Level of evidenceII.
Highlights
Femoroacetabular impingement (FAI) syndrome is a cause of hip pain and reduced range of motion (ROM) in young and active patients
A prominent femoral head-neck junction and/or a prominent acetabular rim causes mechanical conflict in the moving hip, which may lead to damaged soft tissue in the joint [3]
And at the 5-year follow-up, the patients completed a set of self-administered web-based patient-reported outcome scores (PROMs) consisting of the International Hip Outcome Tool [17], the Copenhagen Hip and Groin Outcome Score (HAGOS) [18], the Hip Sports Activity Scale (HSAS) [19], the EuroQoL-5 Dimension Questionnaire (EQ-5D) [20], the EQ-Visual Analogue Scale (VAS) [20] and the VAS for overall hip function
Summary
Femoroacetabular impingement (FAI) syndrome is a cause of hip pain and reduced range of motion (ROM) in young and active patients. FAI syndrome has been proposed as a cause of osteoarthrosis (OA) of the hip [1,2,3,4]. A prominent femoral head-neck junction (cam morphology) and/or a prominent acetabular rim (pincer morphology) causes mechanical conflict in the moving hip, which may lead to damaged soft tissue in the joint [3]. Surgical treatment for FAI syndrome aims to reproduce normal hip anatomy, thereby reducing pain and improving hip function. Several recent studies have reported good results following arthroscopic treatment for FAI syndrome at short- to mid-term follow-ups [5,6,7,8,9,10,11].
