Abstract
1. Methods of correcting flexion contractures of the knee following poliomyelitis fail if posterior subluxation of the tibia is allowed to occur.
2. Careful serial manipulations will give straight, congruous joints in younger patients. Posterior capsulotomy does not facilitate correction.
3. Supracondylar femoral osteotomy is indicated in children over fifteen and in adults, although sometimes arthrodesis of the knee is necessary.
