Summary:

Arthroscopic hip surgery is safe and effective in the treatment of FAI.

Abstract:

Aim: This study presents the results of 150 consecutive hip arthroscopic procedures performed for the treatment of Femoro-acetabular Impingement. The procedures were performed by a single surgeon over a period of 48 months. The results discuss the learning curve and the evolution of the current technique along with the clinical outcomes.

Method: 150 hip arthroscopic procedures were performed for the treatment of FAI. 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 pre-operatively. Post-operative CT scans were 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 SF 12, Modified Harris Hip Score and Non Arthritic Hip Score questionnaires.

Results: Post operatively Modified Harris Hip score improved from 54 to 88, Non-Arthritic hip score improved from 55 to 90, SF12 score improved from 34 to 47. Five patients required a second procedure for further bony resection. Three patients underwent a THR within 12 months. Three patients suffered minor vaginal abrasions. One patient suffered a stress fracture. One patient formed a small false aneurysm requiring excision and ligation.

Conclusion: Arthroscopic surgery is a safe and effective technique in reducing pain and improving function in patients suffering from FAI.
