Knee replacement surgery (also called arthroplasty) is a routine surgical procedure for people with damaged, worn or diseased knee joints. It involves removing the damaged knee joint and replacing it with an artificial joint, made from hard plastic, ceramic or metal.
There are two types of knee replacement surgery, determined by the extent and severity of the damage to your knee joint:
- Total knee replacement involves replacing both sides of the knee joint with an artificial implant.
- Partial knee replacement involves only replacing one side of the joint.
