Abstract
Twenty-two osteoarthritic knees treated by high tibial osteotomy were followed for at least five years. Average JOA score at follow-up was 78.9 points.Cases older than seventy years all achieved good results. The maximum flexion angle decreased by five degrees postoperatively and the mean femoro-tibial angle was 169.8 degrees at follow-up.Seven knees (4 cases) remained symptomatic, and osteoarthritic changes in the patello-femoral joint and lateral femoro-tibial joint were seen in these cases. In the other cases obesity was a predisposing factor.
