What is Knee Replacement Surgery?
Knee replacement, or knee arthroplasty, is a surgical procedure for resurfacing a knee damaged by arthritis. It involves using metal and plastic components to cap the ends of the femur, tibia, and kneecap bones. Arthritis leads to joint degeneration, inflammation, and pain, with osteoarthritis affecting middle-aged adults and causing cartilage breakdown, while rheumatoid and traumatic arthritis result in joint damage. Arthritis knee replacement surgery aims to repair damaged knee joint parts and alleviate pain that cannot be managed by other treatments.
Who needs Total Knee Replacement (TKR)?
A surgeon usually recommends total (TKR surgery) or partial knee replacements, with total knee replacements replacing all three areas of the knee joint, while partial knee replacements only replace damaged areas, often in younger adults who have experienced injury or trauma. Indications for total knee replacement include joint pain, stiffness, limited mobility, and swelling, often due to arthritis. Total knee replacements can either be performed as an open, minimally invasive surgery or as robotic knee replacement surgery.
