Understanding knee replacement surgery, its benefits, recovery process, and treatment options can help patients make informed decisions about their joint health.

What is Knee Replacement?

Knee replacement, also known as knee arthroplasty, is a surgical procedure in which damaged parts of the knee joint are replaced with artificial components made of metal, plastic, or ceramic materials. The goal of the surgery is to reduce pain, restore movement, and improve the overall function of the knee.

Knee replacement is usually recommended when non-surgical treatments such as medications, physical therapy, or lifestyle changes no longer provide relief.

Total Knee Replacement

In a total knee replacement, the entire damaged knee joint is replaced with artificial implants. This is the most common type of knee replacement surgery.

Partial Knee Replacement

Partial knee replacement is performed when only one part of the knee joint is damaged. This procedure preserves healthy portions of the knee.

Revision Knee Replacement
