Abstract
This study presents the results of 60 consecutive hip arthroscopic procedures for the treatment of Acetabulo-Femoral Impingement. The procedures were performed by a single surgeon over a period of 36 months. The learning curve and the evolution of the current technique along with the clinical outcomes are discussed Additionally two new clinical signs of AFI are described, along with the correlation of radiological and arthroscopic findings.
Sixty patients underwent hip arthroscopies. The procedures included labral debridement, labral repair, femoral and/or acetabular osteectomies. All patients underwent MRI examination and three-dimensional CT imaging to identify the impingement lesion. Follow up CT scanning was performed to assess the accuracy of the bony resection. Patients were reviewed at three months and subsequently at twelve monthly intervals. All patients participated in completing questionnaires.
Post-operatively Modified Harris Hip score improved from 54 to 70, Non-Arthritic hip score improved from 58 to 75, SF12 score improved from 35 to 40. Three patients required a second procedure for further bony resection. One patient underwent a THR within 12 months. Two female patients suffered minor vaginal abrasions.
Hip arthroscopy is a demanding procedure. Good clinical results are achieved only when the cause of impingement has been identified and treated.
