Abstract:
Many surgeons feel the use of an unconstrained mobile-bearing knee is contraindicated in cases of severe varus and valgus deformity. In the author's opinion the Sigma LCS rotating-platform knee system can be used in virtually every primary knee irrespective of deformity. The key is to maintain flexion stability by not releasing the lateral collateral ligament in a valgus knee or the superficial medial collateral ligament in the varus knee.

01:23Knee Joint
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...

01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
