Intra-articular Evaluation of High Tibial Osteotomy with Arthroscopic Debridement

High tibial osteotomy was performed in 45 patients (49 knees) with simultaneous arthroscopic debridement of knee joint.Preoperative and postoperative intraarticular evaluations were compared in 49 joints with osteoarthritic changes in medial compartment type and possibility of repair was discussed using this method.Among 49 joints, the subchondral bone was exposed in medial condyle of 47 joints, second look arthroscopy revealed that the exposed bone in 34 condyles were completely covered by fibrous cartilage, in 6 joints partial cartilage ulcers were remained, in 3 joints cartilage fibrillation was observed and in remaining 4 joints no change was seen. Among partially excised menisci, only 5 had retear.This treatment method is found to be satisfactory in intra-articular repair.
