Abstract

The total condylar prosthesis designed at the Hospital for Special Surgery, New York, in 1973 was modified in 1978 by the addition of a tibial polyethylene spine and a transverse femoral cam to provide the function of the posterior cruciate ligament. The results with the total condylar I have been shown to be very satisfactory with a follow-up of 3–5 years [1,4], but specific areas of deficiency [5] were identified. Posterior subluxation was sometimes noted as a consequence of inadequate fit in flexion; the range of motion was 95 ° on average and normal function, defined as unlimited walking, stair climbing and transfer activities without aids, was present in 22% of the cases. This represented an improvement over previous experiences [3] but was still far from ideal.
