Abstract
Our experience is presented in performing arthroscopic partial menisectomy for the treatment of 130 knees for medial osteoarthritis, in 39 men (42 knees) and 83 women (88 knees), aged 39 to 83 (mean: 64.3) . The follow-up period ranged from 6 months to 3 years and 3 months (mean: 1 year and 6 months) .
In our investigation, the Hokudai classification was used for the roentgenographic classification, and the partly modified Fujisawa classification was used for the arthroscopic grade. The pre-and post-operative comparative investigations were conducted applying the scoring of JOA knee evaluation in roentgenographic stage, PTA, and the grade. The cases whose grade had advanced postoperatively and/or in which an additional operation was performed, as well as the postoperative ROM were also investigated.
Good results were obtained in the mean score of all cases, which was increased from 72.5 preoperatively to 84.3 postoperatively. Significant improvement was obtained in cases of stage II and III or with an 1700, but not in those which were stage II-III or more, or had an FTA of more than 1840, because there was great variation in scores. As the grade advanced the score decreased in cases in which the meniscus and especially inarticular surface had a marked tendency. In other cases of advanced stages, good results were obtained although the FTA was increased, and no signs of aggravation were reported.
