When the bones are fully visible to the surgeon, special, guides and precision instruments are used to remove the damaged surfaces and shape the ends of the bone to accept implants. Navigation Calculator is useful at this point. The implants are then attached to bones. When the surgeon is satisfied with the fit and function of the implants, the incision is closed.

How long a joint replacement last? Longevity of the prosthetic knee varies from patient to patient. It depends on many factors, such as the physical condition of a patient, activity level and weight, and the accuracy of implant placement during surgery. It is useful to keep in mind that prosthetic joints are not as strong or durable as a natural, healthy joint, and there is no guarantee that an implant will last the life of a patient. Today, total knee replacement has become a common and predictable procedure. Many patients have pain relief and improved function compared to their condition before surgery. However, with any mechanical joint, the knee components move against each other. Natural fluid in the joint space, called synovial fluid lubricates the implants as it lubricates the bones and cartilage in a natural joint. The prosthetic components do wear as they roll and slide against each other during movement. As with car tires or brake pads, the wear rate depends on the parties on how the knee joint is used. Activities that place great stress on the joint implants, as May is the case with patients heavier and more active, may reduce the lifespan of the prosthesis. Loosening and wear on the plastic parts of the implant may lead to the need for revision surgery to replace worn parts or all of the components. Your doctor will be better able to discuss these issues with you, taking into account your clinical circumstances, the type of implants used and your lifestyle after surgery.
