Who decides whether you will have a total knee replacement operation? Curiously enough, you are the boss, you decide!
- Your surgery depends principally on your willingness to comply with the long, demanding post-operative physical therapy and rehabilitation program that follow the surgery.
- All other considerations (your age, disease character, etc.) are secondary.
- The decision to have the operation of a damaged knee joint is a highly personal matter, and only you can make that decision, together with your surgeon.
The principle of the Computer Assisted total knee operation is simple:
The computer program produces a map of the patient’s knee. The map is reproduced on a large screen. The position of surgeon’s hands and instruments are incorporated in this map too.
The progress of the operation is monitored on the screen. The total knee surgery is turned into something akin to an instrumented landing of an aircraft.
This is theory. In practice, the computer systems used just now in total knee surgery are more simple. (more…)
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…)
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.
