Also, new production techniques, including one that increases the bond between the molecules in the high density polyethylene plastic used, are making the prostheses more durable and less subject to wear. Physicians hope these changes will reduce the need for second replacements such as Mrs. Roberson's. A polished metal end is secured to the femur, while the tibia gets a tough plastic end cupped in a metal tray. A plastic knee cap is also attached. The metal parts mimic bone, while the plastic mimics the cushioning and protection provided by cartilage.
Rehabilitation begins even before the patient wakes up from the anesthetic.
This movement prevents the knees from becoming stiff and promotes good circulation throughout the area. Often a blood thinner is prescribed, also. Faithful adherence to an exercise routine is critical to a good outcome, says Dr. Schoch.
