Abstract
-
PURPOSE: To analyze the results of total knee arthroplasty in severe varus deformed knee and to find out the need of bone grafting.
MATERIALS AND METHODS
36 cases with over 10 degrees varus deformed knees had been operated from April, 1994 to December, 1998. 5 cases received autogenous iliac bone graft. Preoperative femoro-tibial angle, flexion deformities, range of motion and HSS scores were analyzed. RESULT: Range of motion was improved from l08 degrees to 124 degrees, HSS score was improved from 61 points to 92 points. In 5 cases of bone graft, range of motion was improved from 104 degrees to 116 degrees, HSS score was improved from 52 points to 91 points.
CONCLUSION
With adequate bone cutting and ligament balancing, total knee arthroplasty in most cases of severe varus deformed osteoarthritic knee had a good result without bone graft. In case of large bone defect in proximal tibia, bone graft was needed if it is hard to achieve postoperative alignment and stability.
