title: Thrombocytopenia absent radius syndrome and knee deformity.
abstract: We report a case of thrombocytopenia absent radius (TAR) syndrome with varus and flexion deformity and limited movement of the knee. Soft tissue release achieved only partial correction of the deformity and tended to convert a stiff knee to an unstable knee. Flexion deformity required correction by lower femoral extension osteotomy.
