artificial knee joint

An artificial knee joint, also known as a knee prosthesis, is a medical device used to replace a damaged or worn-out knee joint, often due to arthritis or injury. It consists of metal, plastic, and sometimes ceramic components designed to mimic the natural knee's movement. The procedure to implant it, called knee replacement surgery, helps relieve pain, restore function, and improve mobility. Patients typically regain the ability to walk and engage in daily activities, enhancing their quality of life. Advances in materials and technology have made these implants more durable and effective over time.
