The results were reviewed of high tibial osteotomy in 14 patients (17 knees) performed between 1977 and 1982; the mean length of follow-up was 8.9 years in a range of 5.8 to 11.2 years. In most of the cases, the surgery done was wedge osteotomy. Clinical evaluation was made using the knee scoring system of the ‘three universities trial plan’.
All cases except one showed satisfactory results. The evaluation score of knee joint function was an average of 83.6 points compared to a preoperative score of 58.3. The preoperative femorotibial angle (FTA) averaged 185.9°, the postoperative one 169.0°, and the one at follow-up 169.1°. Seven cases showed flexion loss postoperatively, and these had a tendency of developing patella baja and a decrease of the posterior tilting angle of the tibial plateau.
