Purpose: To examine the clinical results after arthroscopic meniscectomy of radial tear of medial meniscus. Materials and Methods: We studied 45 cases with the radial tear of medial meniscus which follow up more than 2 years(range 2 to 7 years). Arthroscopic surgery was performed to the patients with grade 0-2 according to the Kellgren and Lawrence classification. Evaluation of cartilage damage was performed on surgical photos according to Outerbridge classification. Evaluation of clinical result was used the modified Lysholm score. Results: The mean pre-operation Lysholm score was 79.1, 71.2, 68.5, 67.9, 67.2, 61.5 and post-operation Lysholm score was 86.3, 75.1, 73.0, 73.1, 73.2, 66.2 and 61.5%, 62.5%, 60.0%, 50.0%, 50.0%, 25.0% improved knee pain and 69.2%, 75.5%, 70.0%, 66.6%, 75.0%, 75.0% were satisfied knee surgery and 30.7%, 20.5%, 20.0%, 50.0%, 25.0%, 50.0% required further surgery in patients respectively. According to Kellgren and Lawrence classification, 7 cases(15.5%) progress grade 3 osteoarthritis. Conclusions: The radial tear of medial meniscus showed the poor results with arthroscopic meniscectomy even if the grade 0-2 osteoarthritis. For the improvement of the clinical results, consider the technique to restore the hoop stresses or use the high tibia osteotomy for preventing the osteoarthritis.
