Combined Arthroscopic and Mini-Open Treatment of CAM-Type Femoroacetabular Impingement

Abstract

ABSTRACT Purpose Osteochondroplasty of the femoral head-neck junction can improve hip pain and function in patients with femoroacetabular impingement. We report our initial series of patients undergoing surgical treatment for symptomatic CAM type femoroacetabular impingement using a combined arthroscopic and mini-open approach. Materials and methods A retrospective chart review of 20 consecutive patients was performed. Seventeen patients had adequate follow-up for inclusion. Preoperative clinical and radiographic characteristics as well as intraoperative findings were obtained from patient records. Postoperative Harris Hip scores and VAS pain scores were recorded at final follow-up. Results At an average of 27.8 months (range 12-48 months), the mean Harris Hip score improved from 64.7 preoperatively to 86.8 (p < 0.001). The mean VAS pain score improved from 4.80 to 1.53 (p = 0.001). Two patients (11.7%) underwent total hip arthroplasty at an average of 15 months postoperatively. Fourteen patients (82%) stated they would have the procedure again. There were no significant complications. Conclusion Surgical treatment of CAM type femoroacetabular impingement using a combined arthroscopic and mini-open anterior hip approach has a low complication rate and improves functional and pain scores at short-term follow-up.
