ABSTRACT

[Objective]To investigate the method and efficiency of operative femoral supracondylar varus osteotomy combined with new blade plate on treatment of valgus deformity of knees.[Method]Thirty-seven patients with 43 knees with valgus deformity were treated with femoral supercondylar varus osteotomy with Giebel blade plate(Link company/Germany)from Oct.2000 to Oct.2005.The study group consisted of seven men with 8 knees and thirty women with 35 knees,the average age of the patients was 31.2 years(range,fifteen to seventy years).Eleven patients with 13 knees had lateralcompartment osteoarthritis,Ahlback stage Ⅰ eight patients with 10 knees and stage Ⅱ three patients 3 knees.The full-length Ap view of the lower extremity and the weightbearing AP view of the knee were obtained before and after operation,as well as the femoral angle and femoral-tibial angle were evaluated.The Giebel blade plates were taken out average 1.5 year after operation and the patients were followed-up,bone union and the change of the correction angles and the pain of the knees were evaluated.[Result]All deformity of the knees were well corrected,the femoral angle were corrected from 71.7?(62?～75?) to 82.1?(78?～85?),the average correction angle was 10.4?(8?～21?).With average 1.5 year follow-up thirty four patients with 40 knees got good bone union,two knees had non-union and we changed the internal fixationwith bone autc-grafting and got good results,as well as lost follow-up for one knee.The pain relieved in 10 knees with lateral osteoarthritis and disappeared in 3 knees after operation.[Conclusion]Femoral supracondylar varus deformity of the knee,the technique is simple and damage is slight,fixation is safety and effective.
