Your doctor carefully considers factors such as age, health status, weight, and activity levels before determining the appropriate treatment method. Non-surgical treatment options may be suggested for less severe knee pain. These treatments may include rest, drugs and analgesics. When non-surgical options fail to provide adequate pain relief, knee replacement may be suggested. If you are in pain, you should discuss treatment options with your surgeon. One such option is a total knee replacement.
Total knee replacement or total knee arthroplasty is the surgical replacement of the end of the Femur (thigh bone) and the top of the Tibia (shin bone) as well as the undersurface of the Patella (knee cap) with artificial parts called prostheses. There are four components that make up a total knee replacement. The Femoral Component and the Tibial Component are both metal and the Patella Component and the Bearing Insert are Polyethylene (High strength plastic).
In Traditional Knee replacement surgery, your incision will be right over the top of your knee cap which allows access to the knee joint. The Femur, Tibia and Patella are prepared using special instruments provided by the manufacturer. This allows a perfect fit of the prostheses to your anatomy. This also allows the surgeon to correct defects in the alignment of your knee (Knock-kneed or bow legged).
