For the purpose of study of instability of knee we performed MRI examination added to the manipulative tests of instability of knee to judo athletes. 6 of 18 subjects with instability of knee judged by manipulative tests had the instability filled with criteria that we had made to judge the grade of instability. Findings of MRI examination in this 6 athletes were showed that there were two subjects with anterior cruciate ligament-deficient knee and 4 suspected tear of ligaments with damaged tension of ligament fibers. MRI finding were showed 3 meniscus tears and one of 3 cases with valgus instability was injured MCL of knee. Ability of judo activity was evaluated in results of competition, 2 of 6 cases with anterior instability of knee had poor results, one of 6 cases had good results, other 3 cases had no major change.
