The results of 4 supracondylar femoral varus osteotomy that were done for lateral osteoarthrosis were evaluated. The mean age of patients was 66.5 years old. The length of follow up averaged 7 years and 5 months (range 6 to 9 years). The preoperative tibiofemoral angles of each cases were 167°, 162°, 150° and 164° which were corrected to 180°, 184°, 183° and 172°. At the last follow-up study, they changed to 183°, 180°, 198° and 167°. It seemed difficult to predict the post operative change of tibiofemoral angle.
According to the Japanese Orthopaedic Association knee score, it improved from an average of 72.5 points preoperatively to 83.8 points post operatively. All patients expressed satisfaction with the outcome.
