How is a knee implant affixed in the body?
Knee implant systems are affixed in the body in one of three ways: 1. Cemented with bone cement: A special type of acrylic bone cement may be used to secure some or all of the implant components to the bone. The bone cement takes about 15 minutes to set. 2. Cementless (biologic ingrowth): Implant components using cementless implantation have a special porous coating that allows tissue to grow into it for fixation. 3. Combination: In some cases, your surgeon may choose a combination of cement and cementless attachment, depending upon the implant components and the condition of the bone around the knee joint. The decision as to whether to use a cemented or cementless component depends upon many factors, including the intended use of the product, surgeon philosophy and the patient%u2019s condition.
