Knee Replacement Surgery is also referred as Total Knee Replacement or Total Knee Arthroplasty. This surgical procedure is performed to replace the damaged joint of the knee with an artificial joint which is made from plastic or metal material. These artificial components are called as prostheses. Knee Replacement Surgery is recommended to patients who are suffering from severe pain and loss of function from arthritis and have failed results from other conservative methods of therapy.
Types of Knee Replacement Surgery
There are two types of knee replacement surgery: Total Knee Replacement and Partial Knee Replacement. The type of approach used varies from patient to patient depending upon their condition.
Total Knee Replacement (TKR):- Total knee replacement surgery is a traditional method for repairing the damaged knee. Advancements in medical technology have led to precise and highly functional artificial knee implants which duplicate the functions of the normal and healthy knees. Most total knee replacement surgery involves replacing of the joint surfaces at the end of the thigh bone (femur) and the top of the shin bone (tibia). This surgery also involves replacing the undersurface of the kneecap (patella) with a smooth plastic dome. The artificial implants used are placed in a place with the help of cement. After the artificial implants are fit together the attached artificial parts from the joint, relying on the surrounding muscles and ligaments for support and function.
Partial Knee Replacement (PKR):- Partial Knee Replacement surgery is also referred as uni-compartmental knee replacement surgery. This surgery involves replacing of only a part of the knee in order to preserve as much as the original healthy bone and soft tissues as possible. Partial Knee Replacement surgery is performed in three anatomical compartments of the knee the lateral compartment outside of the knee, the patella femoral compartment outside the knee or in the front of the knee between the thighbone and kneecap. This surgery is generally recommended to patients who have osteoarthritis in only one compartment of their knee.
