What is Knee Replacement Surgery?
Knee replacement surgery, also known as Total Knee Arthroplasty (TKA), is a surgical procedure in which the damaged cartilage and bone of the knee joint are replaced with artificial implants made of high-quality metal alloys, ceramic, and medical-grade polyethylene.
The primary goal of the surgery is to relieve chronic pain, restore knee function, improve mobility, and help patients return to an active lifestyle.
Every year, thousands of patients from Africa, the Middle East, Central Asia, and other parts of the world travel to India for knee replacement surgery to regain mobility, reduce pain, and improve their quality of life.

Types of Knee Replacement Surgery
Total Knee Replacement (TKR)
The entire knee joint is replaced with artificial implants. Ideal for advanced arthritis affecting the entire knee.

Only the damaged compartment of the knee is replaced. Suitable for selected patients with localized arthritis.
Bilateral Knee Replacement
Both knees are replaced during one surgical session or in staged procedures. Recommended for patients with severe arthritis in both knees.
Robotic Knee Replacement
Robot-assisted technology improves implant positioning, precision, alignment, and soft-tissue balancing, potentially enhancing surgical accuracy and recovery.
Revision Knee Replacement
Performed when a previous knee replacement has worn out, loosened, become infected, or failed.
