Knee Replacement
Reemplazo de rodilla
Also: Artroplastia de rodilla (regional variant)
What it means
Knee replacement is a surgery to replace parts of the knee joint with new, artificial parts. During the surgery, a surgeon removes damaged cartilage and some bone from the surfaces of the knee joint and then attaches artificial parts made of metal and plastic. The surgery may replace all the damaged parts of the knee (total knee replacement) or just part of the knee (partial knee replacement). It is usually done when other treatments for knee pain have not helped enough, and knee osteoarthritis is the most common reason for it. The goal is to relieve pain and help a person move better. MedlinePlus also calls the surgery knee arthroplasty, and its encyclopedia article calls the artificial joint a prosthesis.

The two scopes of the surgery are reemplazo total de rodilla and reemplazo parcial de rodilla.
The encyclopedia article calls the artificial joint a prótesis, a feminine noun that the Spanish dictionary defines as a piece or device used to replace an organ or a limb of the body.
