[Intermediate term results following supra-tubercular corrective osteotomy of the head of the tibia].

In the operative therapy of gonarthrosis the supratubercular osteotomy of tibia head has a solid position. In the present work the results of subtractive and additive intraligamentous correction osteotomy with following fixation in plaster dressing on the orthopaedic clinic of the district hospital Aue will be explained. In the period from 1982-1987 35 supratubercular tibia head correction osteotomies in 32 patients with unicondylar gonarthroses were carried out. These were examined on an average of 2.8 years (0.8-5.4 years) post operative. The supratubercular correction osteotomies were composed of 27 valgus and 8 varus operations in corresponding axis deviation. 85 per cent of all examinated patients were satisfied and very satisfied with the operation results. This justifies the further execution of the named operative method. Among the 15 per cent of the unsatisfactory operation results were mainly gonarthroses of higher severities and rheumatoid arthritis. The results shows, that in the last cases the indication is stronger to make and the possible unilaterale or totale arthroplasty--especially in higher living age--are take into consideration.
