Our experience is presented in performing arthroscopic partial menisectomy for the treatment of 130 knees for the medial osteoarthritis.The patients were 39 men (42 knees) and 83 women (88 knees), and aged 39 to 83 years old (the mean: 64.3 years old). The follow-up period ranged from six months to three years and three months (the mean: one year and six months).We used the Hokudai classification for the roentgenographic classification, and the partly modified Fujisawa's classification for the arthroscopic grade. The comparative investigation of pre-and post-operation was conducted applying the scoreing of JOA knee evaluation in each of the following items: the roentgenographic stage, the grade, FTA. The good result was obtaind in the mean score in all cases, which was increased from 72.5 in preoperative score to 84.3 in post-operative one. The significant improvement was obtained in stage I and II but no significant difference in stage III and IV because the scores were sporadical. As the grade was advancing, the obtained score was decreasing in meniscus and especially in articular surface with the marked tendency.
