Knee replacement surgery or knee arthroplasty is one of the most successful procedures to be performed in the field of medical science. Best suited for those who suffer from arthritis of the knee or chronic knee pain, knee replacement surgery involves replacing damaged, injured or fractured parts of the knee with metal and plastic plates. By reducing knee pain and instability, knee replacement surgery enables patients to enjoy a good quality of life again, as they are then able to participate in normal daily activities like walking.
During a knee replacement procedure, your surgeon will begin by properly preparing the bone. This involves removing the damaged cartilage on the femur and tibia, as well as some of the underlying bone. Once the damaged cartilage has been removed, your surgeon will position the artificial implants in place. The implants are made up of metal components, which are secured in place with surgical cement.
In some cases, the surface of the kneecap is also resurfaced with plastic before a component known as a spacer is placed between the new artificial components, allowing for smooth movement in the knee.
Patients who undergo knee surgery generally experience improved mobility, as the procedure is very successful in relieving knee pain and stiffness. It is also recommended for those who suffer from severe inflammation and swelling in the knee, and those with a knee deformity.
A knee replacement is often a good option for patients who suffer from osteoarthritis, rheumatoid arthritis and post-traumatic arthritis. These conditions cause damage to the cartilage, resulting in pain and difficulty with proper knee function.
The potential benefits of a minimally invasive approach to knee replacement include:
