[Management of varus knee arthrosis by high tibial osteotomy].

Authors made a follow-up of 69 varsus knee arthrosis treated with high tibial osteotomy. Beside the general results the effect of the severeness of the arthrosis before the correction and that of the gain of the axial correction on the result were also investigated. 56 (81 per cent) of the reexamined patient reported excellent or good results. The ratio of the successful operations was even higher in cases in which the femorotibial axis was corrected to physiological valgus (95 per cent). The best prognosis of the osteotomy is in the early stage of arthrosis (Ahlbäck 0-II). In cases of the more advanced process the ratio of the unsuccessful cases increases. In consequence it is stated that the best results can be expected after osteotomies performed in the early stage and leading to the physiological femorotibial valgus position.
