Knee replacement, also known as knee arthroplasty, is a surgical procedure performed to replace damaged or worn-out parts of the knee joint with artificial components. It’s typically recommended for individuals with severe knee pain or limited mobility due to conditions like osteoarthritis, rheumatoid arthritis, or traumatic injury. During the procedure, the damaged bone and cartilage are removed from the knee joint and replaced with metal and plastic implants designed to mimic the natural knee’s movement and function. Knee replacement surgery aims to relieve pain, improve mobility, and enhance overall quality of life for patients. While it’s generally considered safe and effective, it requires thorough pre-operative assessment and post-operative rehabilitation to achieve optimal outcomes and minimize risks such as infection, blood clots, and implant failure.
