A retrospective analysis of twenty-three spastic patients who underwent
forty-three transfers of the semitendinosus muscle to the lateral
intramuscular septum and of the semimembranosus muscle to the biceps is
presented. Decreased knee-flexion deformity as well as improved walking
function were achieved in 91 per cent. An unsatisfactory result was
associated with complications of the procedure. Only one knee of the
forty-three that were operated on showed late genu recurvatum. This
procedure appears to be both effective and relatively free of late
comlications.
