About Total Knee Replacement
Total Knee Replacement (TKR) is a surgical procedure in which a damaged knee joint is replaced with an artificial implant (prosthesis) made of metal alloys and medical-grade polyethylene. The procedure removes diseased cartilage and bone from the knee joint surfaces and replaces them with precisely fitted metal and plastic components that replicate the natural shape and function of the knee. TKR is one of the most successful surgical procedures in orthopaedics — providing lasting pain relief and significantly improved mobility for patients with severe knee arthritis.

Surgical Procedure
Under spinal or general anaesthesia, an incision is made over the front of the knee. Damaged cartilage and bone surfaces are precisely removed from the femur, tibia, and patella using cutting guides. The metal and polyethylene components are then fixed in place using bone cement (cemented technique). The knee is taken through a range of motion to confirm stability and alignment before closure. A drain may be placed for 24 hours. The procedure typically takes 2–3 hours.
