Abstract:
PURPOSE: This study examined the wear pattern of the articular cartilage of the medial tibial plateau with or without a functional ACL in patients with degenerative osteoarthritis of the knee. MATERIALS AND METHODS: Between July 2003 and May 2004, 71 cases (52 patients) of total knee arthroplasty due to degenerative osteoarthritis of the knee were enrolled in this study. The intraoperative evaluations such as a test for the functional status of the ACL and the wear pattern of medial tibial plateau were performed, and the associations with the physical examinations such as, range of motion (ROM), Lachman test and pivot shift test, and tibio-femoral angle (TFA), were analyzed. RESULTS: There were 43 cases with a functional ACL, and the wear pattern of the medial tibial plateau was differentiated as anteromedial and central in 8 cases (18.6%), central in 30 cases (69.8%), and central and posteromedial in 5 cases (11.6%). There were 28 cases with a non- functional ACL and the wear pattern of the medial tibial plateau was differentiated as anteromedial and central in 1 case (3.6%), central in 2 cases (7.2%), and central and posteromedial in 25 cases (89.2%). In the group with the non-functional ACL, the most prevalent wear pattern was central and posteromedial (p<0.001). CONCLUSION: In patients with degenerative osteoarthritis of the knee without a functional ACL, the wear pattern of the articular cartilage of the medial tibial plateau was more posteromedially than patients with a functional ACL.
