Abstract

PURPOSE: To evaluate clinical and radiographic results associated with the use of autogenous bone graft with preservation of cortical bone in the patients with severe bone defect of the proximal medial tibia in total knee arthroplasty. MATERIALS AND METHODS: From January 2000 to June 2003, thirty three primary total knee arthroplasty were performed with autogenous bone graft for severe peripheral defect of the proximal medial tibia. After sclerotic bone of defect site was removed by the burr, reconstruction of medial wall was done by use of resected bone, which was fixed by wedge-shaped bone. Autogenous cancellous bone was grafted in the central type bone defect area. We reviewed the result using the HSS knee rating scores and observed the radiographic changes. RESULTS: The mean HSS knee rating score was 43.5 preoperatively and was 91.3 at last follow-up. Radiologically, union of the tibial bone grafts were impossible to determine, but there were no evidence of the displacement of grafted bone, osteolysis and loosening of the inserted implants. CONCLUSION: The method of autogenous bone graft applied with preservation of cortical bone and wedge bone graft could be supposed as useful in the reconstruction of the tibial bone defects as well as in the stability of the tibial component.
