These total knee prostheses permit flexion and extension and allow for a limited rotation. The linked total knee prostheses, however, prevent movements to both sides (abduction and adduction) of the knee joint. That is their purpose: to provide the total knee with intrinsic side stability.
The limited amount of rotation, that these prostheses allow, improves gait and decreases stresses on the bone -skeleton interface created by walk and other activities. Thus, in contrast to the old true hinged total knees, the linked total knee prostheses have lover rates of complications. (more…)Read More

The name “Total Knee Replacement” is a misnomer.
In this operation, the surgeon removes only the damaged surfaces of the knee joint and then covers them with surface shells made of metal and polyethylene.
The proper name would thus be “the surface replacement of the knee joint”.
Here follows only a very short course on the principles of the operation itself.Read More
