Are there different kinds of implants?
A. Yes! There are many types of knee implants that fit into broad categories related to their interaction with the remaining natural soft tissue. For example a CR or Cruciate Retaining knee implant is designed to work with the PCL (posterior cruciate ligament) intact. Other types of implants are designed to work without it. In addition, there are many manufacturers of implants which create several brands of knees in each of the broad categories. Surgeons have many, many choices. More onTypes of Knee Implants.
