knee replacement surgery is a medical procedure that involves removing damaged or worn-out parts of the knee joint and replacing them with artificial components. This surgery is often recommended for individuals suffering from severe osteoarthritis, rheumatoid arthritis, or other knee-related conditions that cause pain and limit mobility. The procedure can be performed as a total knee replacement, where both sides of the joint are replaced, or a partial knee replacement, which addresses only one side. Recovery typically involves physical therapy to help restore strength and movement, allowing patients to return to their daily activities with reduced pain.
