Abstract/Text
INTRODUCTION: Surgical treatment of femoroacetabular impingement can be performed under arthroscopic control, to limit associated morbidity. Encouraged by recent good reports, arthroscopy is replacing alternative techniques for this indication.
HYPOTHESIS: Arthroscopy enables femoroacetabular impingement to be corrected with a low rate of associated morbidity.
AIM OF STUDY: To assess the indications for and quality of the technique and its impact on preliminary results and complications. To investigate preoperative prognostic factors.
PATIENT AND METHODS: One hundred and eleven hips in 110 patients (78 male, 32 female; mean age, 31 years) were operated on under arthroscopic control for femoroacetabular impingement, by six senior surgeons. Sixty-five patients showed no radiographic sign of osteoarthritis, and 36 showed grade-1 early osteoarthritis on the Tönnis scale.
RESULTS: Mean WOMAC score rose from 60.3 preoperatively to 83 (p<0.001) at a mean 10 months' FU (range, 6-18 mo). Seventy-seven percent of patients were satisfied or very satisfied with their result. Patients with early osteoarthritis had significantly lower WOMAC and satisfaction scores than those free of osteoarthritis. Operative crossover to open surgery occurred in only one case. Five patients (4%) had revision: total hip replacement or resurfacing. There were seven complications (6%): three cases of heterotopic ossification, one of crural palsy, one of pudendal palsy, one of labium majus necrosis, and one non-displacement stress fracture of the femoral head/neck junction (managed by non-weight-bearing). There was no palsy of the territory of the lateral cutaneous nerve of the thigh.
DISCUSSION: Results confirmed the efficacy and low associated morbidity of arthroscopy in the management of femoroacetabular impingement. Short-term functional results matched those of the literature. Planning and assessment seem not yet to be fully standardized. Preoperative osteoarthritis on X-ray was associated with poorer functional results. This attitude does not seem to be indicated for hips showing evolved osteoarthritis (>grade 1).
