A 5-year Follow-up Study of Anterior Cruciate Ligament Reconstruction – Radiographic Evaluation of Osteoarthritis Changes

Our purpose was to evaluate osteoarthritis (OA) changes on X-ray after ACL reconstruction and the associated affecting factors. The study assessed 31 ACL reconstructed knees: 11males and 20females. We treated chronic ACL-deficient knees by reconstruction of the ligament using one-third of the patellar tendon. OA changes on X-ray were evaluated by using the scoring system of Keio University. In this system, OA changes were investigated three parts of the knee joint (P-F joint, Medal part and Lateral part of T-F joint) and were scored. We evaluated knee stability, the period of operation from injury, Lysholm score…
