Understanding Knee Replacement Surgery

Knee replacement surgery, also known as total knee arthroplasty (TKA), is a surgical procedure. It replaces the weight-bearing surfaces of the knee joint with artificial parts. This surgery aims to relieve severe knee pain and restore function in patients with damaged knee joints.

What is Total Knee Arthroplasty (TKA)

Total knee arthroplasty (TKA) is a surgery that replaces the knee joint’s damaged surfaces with prosthetic implants. The procedure resurfaces the femur, tibia, and sometimes the patella with artificial parts. These parts are made of metal alloys, high-grade plastics, and polymers.

The goal of TKA is to give patients a pain-free knee that moves naturally. The surgery is often recommended for those with severe knee arthritis or other degenerative conditions. It can greatly improve their quality of life by reducing pain and improving mobility.

Common Reasons for Knee Replacement

Knee replacement surgery is most commonly done for osteoarthritis. This is a degenerative joint disease that wears away the cartilage in the knee joint. Other conditions like rheumatoid arthritis, post-traumatic arthritis, and avascular necrosis may also require TKA.

In some cases, knee replacement is needed for patients with certain types of knee fractures or deformities. The decision to have TKA is made after trying other treatments like medications, physical therapy, and injections. Robotic-assisted knee replacement surgery is a precise method for performing TKA, aiming for better outcomes for patients.

Types of Knee Replacement Proceduresh, and the doctor’s advice.

Total Knee Replacement (TKR/TKA)
