A case of arthroglyposis multiplex congenita with bilateral flexion contracture of the knees was reported. A girl with flexion contractures of her knees and hips and equinovarus deformities of her both feet underwent operative procedures including distal femoral extension osteotomy with shortening of the femur and anterior tendon transfer of the hamstrings on both knees. At twenty-two months after the operation, she was able to walk alone with short leg braces and crutches.
