What are some of the situations that require hip revision surgery?
Component failure The most common reason for hip implant failure is the wearing down of the plastic insert in the hip socket. In some other cases, the hip implant may shift slightly after surgery leading to unbalanced weight distribution and premature implant failure. Depending on the the kind of failure and the extent of the wear, only the plastic component or the entire implant together with the metal components will be replaced.
