Abstract

PURPOSE
We wanted to report the clinical results of arthroscopic resection of osseous abnormality that caused femoroacetabular impingement
MATERIALS AND METHODS
Among 38 cases of patients who had their causes diagnosed as femoroacetabular impingement and who were treated by arthroscopy from April 2000 to August 2005, 21 cases of the patients who were operated on for resection of the acetabular labrum before August 2004 are categorized as group 1; after that, 17 cases of patients who were operated on for bumpectomy or acetabuloplasty were categorized as group 2.
RESULTS
The pain scores for all the patients during the preoperative phase, the 2nd week, the 6th week, the 3rd month, the 6th month and the 1st year were 0.57, 1.57, 2.10, 2.19, 2.38 and 2.33, respectively, for group 1 and 0.65, 0.59, 1.41, 1.65, 2.12 and 2.47, respectively, for group 2, which showed improvement from the medical view. The differences between the pain scores of the preoperative phase and the 2nd week postoperatively were an average of 1.00 and -0.06, respectively, in group 1 and group 2, which showed aggravation of the clinical condition of group 1 compared to that of group 2. The differences between the pain scores of the preoperative phase and the 1st year of the postoperative phase were an average of 1.76 and 1.82 in group 1 and group 2, respectively, which presents the better improvement in the medical condition of group 2. 15 out of 21 people in group 1 (71%) and 14 out of 17 people in group in group 2 (82%) were satisfied after the operation.
CONCLUSION
Removal of osseous deformity through arthroscopy, compared with the aspects of the clinical conditions as based on the result of partial labrectomy, causes pain in the early days of the postoperative phase. However, the results of the 1 year progression of postoperative phase present a favorable turn of the patients' clinical condition.
