Hip and knee replacements are the most frequently done joint replacement surgery. The damaged hip or knee bone is removed and replaced by a plastic, metal, or ceramic part, which replicates the function of the body part. They are called prostheses. Joint replacement by a prosthesis is advised when a joint becomes nonfunctional, is broken irreversibly, or causes too much pain on movement, for example, accident, trauma, arthritis, SLE, etc.
