Abstract

PURPOSE
To report the mid- and long-term follow up results of patients who underwent arthroscopic treatment after being diagnosed with femoroacetabular impingement.
MATERIALS AND METHODS
72 consecutive patients diagnosed with femoroacetabular impingement underwent arthroscopic partial labrectomy and femoroplasty(79 cases). In order to evaluate the clinical results, a modified Harris hip score, and VAS and Hip outcome scores were utilized. In addition, the alpha angle and femoral offset were measured radiologically.
RESULTS
Based on the clinical results from all consecutive patients, the preoperative mean pain score was 6.0 and 1.7, and 2.1 points on the mid-(2-5 years) and long-term(5-7 years) follow ups, respectively. The mean modified Harris hip score improved from 58.9 points to 81.9 and 79.3 points for the mid-term and long-term follow up groups, respectively. Prior to surgery, the daily activity scale and motor scale results associated with Hip outcome scores were 59.2 and 57.5 points for the mid- and long-term groups, respectively. These scores improved to 84.7 and 84.5, and 81.2 and 79.5 for each group upon the mid- and long-term postoperative follow ups, respectively. Based on the radiological results, the mean alpha angle decreased from 61.2degrees preoperatively to 40.9degrees after surgery, and the mean femoral offset increased from 4.8 mm to 10.0 mm.
CONCLUSION
The mid- and long-term clinical and radiological follow ups to evaluate the results of arthroscopic treatment of femoroacetabular impingement revealed satisfactory improvement. This finding further demonstrates that arthroscopy is an effective and safe treatment for cases of femoroacetabular impingement.
