An artificial knee joint can be fixated in a variety of ways. In essence, there are two main types of fixation: cemented and cementless:
- If the bone structure lacks stability, the knee joint replacement is fixated using bone cement. This creates a strong bond between the knee endoprosthesis and the bone immediately after the surgery.
- If the bone quality is good, the artificial knee joint can be fixated without using cement. In this case, the bone slowly grows into the knee endoprosthesis and it takes some time to create a strong connection.
The correct choice of procedure not only depends on the age and physical activity of the patient, but also on the condition of the bone. The surgeon decides on the appropriate method with the patient during a preoperative consultation.
