Partial Knee Replacement

What is partial knee replacement?

Partial knee replacement surgery is one of the most successful procedures to be performed in the field of medical science. Best suited for those who suffer from arthritis in one area of the knee or chronic knee pain, partial knee replacement surgery involves replacing part of a knee with metal and plastic plates. The procedure is recommended for patients whose injury or disease affects only a part of the knee, and do not require a total knee replacement. By reducing knee pain and instability, partial 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.

How does it work?

During a partial knee replacement procedure, your surgeon will begin by properly preparing the bone. This involves removing the cartilage on the damaged part of your knee, 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. A component known as a spacer is placed between the new artificial components, allowing for smooth movement in the knee.

What are the benefits?

Patients who undergo partial knee replacement 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 partial knee replacement is often a good option for patients who suffer from osteoarthritis, rheumatoid arthritis and post-traumatic arthritis in just one area of the knee. 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 partial knee replacement include:

• Less postoperative pain
• Quicker recovery of function
• A shorter stay in the hospital
• Less scarring
• Reduced risk of infection
• Provides a more "natural" feeling knee
• Improved function
• Better quality of life
