Total knee arthroplasty after failed proximal tibial valgus osteotomy.
The results of total knee arthroplasty were evaluated in 113 patients with gonarthrosis (14 patients with and 99 without prior operation with proximal tibial valgus osteotomy). There was no difference in the final result after follow-up periods of 4-9 years with respect to average Hospital for Special Surgery score. degree of knee flexion, and later knee revisions between the 14 osteotomized and 99 nonosteotomized patients. The average femorotibial angle did not differ between the groups; neither did the average wear of the tibial polyethylene. No difference was found in operative time, but a significantly greater blood loss and other postoperative complications were noted among the previously osteotomized group of patients, indicating a more complicated procedure for the knee arthroplasty operation compared with the nonosteotomized group of patients.
