Severe grades of genu recurvatum can be successfully treated by inserting a bone graft into the upper end of the tibia. The graft, fusing with the tibia and the patella, forms a bone block which effectually prevents hyper-extension. The graft bears the same relationship to the tibia as the olecranon process to the ulna, and the operation might therefore be summarized as a conversion of the knee joint into an elbow. Great care must be taken not to maintain the overcorrected position too long, since otherwise a flexion contracture is likely to ensue.
