Eighty-one patients (98 knees) with varus gonarthrosis who had a high tibial osteotomy were followed for at least ten years, the average follow-up being 14 years. The results showed that the rate of knees graded as satisfactory was 87% at 2 years, 77% at 7 years, and 66% at the last follow-up evaluation.
Factors influencing long-term results were age at the time of surgery, preoperative roentgenographic stage, postoperative femorotibial angle, obesity, and degenerative changes of the opposite knee and the lumbar spine.
We believe that the alignment obtained by osteotomy is the most important factor in bringing good long-term results, and the optimum femorotibial angle should be 168° (166°-170°) .
