Uptilting osteotomy of the lateral tibial plateau for a knee deformity. A case report.

A middle-aged woman had had anterior poliomyelitis at 11 years of age that had left her with residual weakness in both legs. She gradually developed a recurvatum and valgus deformity in both knees, which caused pain and instability. A technique to restore the top of the tibia by means of a rotational osteotomy of the lateral tibial plateau is presented. This operation resulted in painless, asymptomatic knees and improved function.
