The definitive improvement in quality of life, in combination with the aging of the population, has led to an increasing demand for total knee arthroplasty. While cruciate-retaining and posterior-stabilized devices will perform well for the vast majority of patients presenting as candidates for primary total knee arthroplasty, the orthopaedic surgeon occasionally encounters cases of advanced severity (Figs. 1-A and 1-B)1-4. Complex presentations range from higher degrees of ligamentous incompetency to severe restriction of the range of motion with substantial flexion contracture to posttraumatic arthritis and to post-osteotomy deformity of either the distal part of the femur or the proximal part of the tibia. The challenge confronting the reconstructive surgeon is to obtain a well-balanced flexion-extension gap with balanced collateral ligaments. This is frequently best accomplished with a modular system that offers a continuum of . . . [Full Text of this Article]
