knee joint prosthesis

A knee joint prosthesis, or knee replacement, is a medical device used to replace damaged or worn parts of the knee joint, typically caused by arthritis or injury. It consists of metal and plastic components that mimic the natural surfaces of the knee, allowing for smoother movement. During surgery, the surgeon removes the damaged bone and cartilage and replaces them with the prosthesis, restoring function and reducing pain. The goal is to improve mobility and quality of life by providing a durable, functioning artificial joint that can last many years with proper care.
