Total Knee Replacement has another term as Total Knee Artrhoplasty. This is a surgical procedure, in which the damaged, diseased or worn knee joint is replaced with an artificial surface, after removing the original one.

The knee in the human body is the largest joint present. It is much needed for the daily activities. Knee is made with the combination of upper end of shinbone, lower end of thighbone and kneecap. The network of these three bones is covered with a smooth substance called articular cartilage. This substance enables the bones to move easily and protect them. Wedges are present here and act just like a shock absorber and also help the joint to cushion.
Knee pain or knee disability is generally caused from arthritis. There are many kinds of arthritis and out of them, the most of the pains are caused from rheumatoid arthritis, osteoarthritis and post traumatic arthritis.

Total knee replacement surgery is performed in four basic steps.
- Preparation of the bone
Preparation of the bone involves the removal of the cartilage surfaces that are damaged. These cartilage surfaces are removed from the ends of tibia and femur. Along with that, underlying bone is also removed in a small amount.
- Positioning the metal implants
The bone and the cartilage that are removed would be replaced with a new metal component. The new metal component recreates the surface present over the joint. The metal parts replaced may be either press-fit or cemented and fixed into the bone.
- Resurfacing the patella
The kneecap or patella that is present in the undersurface is cut. It then is resurfaces with a new plastic button. However, all the knee replacements do not need this resurface and the decision is made by the surgeons, based on the special conditions of the patient.
- Insertion of a spacer
A spacer, which is made up of a medical grade plastic is inserted in between the components made of metal. These metal components are inserted for creating the surface that is smooth gliding.
The total knee replacement surgery is also associated with various complications, possibly just like any other surgery.
The complications are
- Blood clots
- Neurovascular injury
- Continued pain
- Implant issues
After the knee replacement surgery is completed, the patient needs to have a stay in the hospital for several days in the hospital. During the stay in the hospital, the patient is taken care in terms of pain management, blood clot prevention, physical therapy and prevention of pneumonia.
