An artificial knee joint can be secured into the bone in a number of different ways. In essence, there are two main types of fixation – with cement or cementless:
- If the bone structure lacks stability, the knee joint replacement is secured using bone cement. Immediately after the operation, the knee endoprosthesis and bone are thus securely bonded.
- If the patient’s bone is of good quality, the artificial knee joint can be secured using a cementless technique. With such methods, the bone slowly grows into the knee endoprosthesis to form a strong joint after some time.
The correct choice therefore not only depends on the patient’s age but also on the nature of the bone. The surgeon decides upon the appropriate method together with the patient during the preoperative discussion.
