Clinical-radiological results of the tibial osteotomy of valgization by internal addition in Gonarthrosis.

In knee osteoarthritis, medial-opening tibial osteotomy remains a good surgical technique, and have been effective in stabilizing and even improving osteoarthritis, Our study is about 20 cases of gonarthrosis on genu varum, treated by opening wedge valgus high tibial osteotomyconducted within the orthopedic trauma department '' B'' of the University Hospital Mohamed VI of Marrakech, over a period of 4 years. The mean age of our patients was 49 years (39-60), with a sex ratio of 1M/4F. In 55% of cases (11 cases) thegonarthrosis was related to primitive genu varum, while 45% cases (9 cases) was secondary to trauma ormeniscectomy. Clinically the knee pain was the main symptom in all cases, with an intensity level 3 on the simple verbal scale. The imagery was designed to measure angular deviations and surgical correction and monitoring the evolution. Angular deviation adjusted mean was 10.3 ° (6 ° -16 °), stages II and III of Ahlback classification, represent the mostcases of tibiofemoral osteoarthritis (90%).The filling was done by autologous bone graft, and the average degree of varus correction was 9.6 °.The results evaluated by the IKS score were excellent or good in 60% of cases for the knee score and 73% for the function score.
