may continue to have pain, requiring medication. Not all implants last for twenty years, but if the original bone cuts were conservative enough, a second implant is placed. The orthopedic surgeon makes an incision over the infected knee. The patella (knee cap) is removed. Then the heads of the femur and tibia are shaved to eliminate any rough spots and permit better adhesion to the prosthesis. The two parts of the prosthesis are implanted into the thighbone and the tibia bone using special cement. Knee joint replacement may be recommended for any of the following conditions: constant knee pain over an extended period of time, osteoarthritis or arthritis, knee fractures or tumors. Morbid obesity (over 300lbs), which may be the cause of functional breakdown, is a contraindication for knee replacement. Complications and risk involve with knee replacement surgery are deep venous thrombosis, hemotoma, loosening and fracturing (Fu, Harner, Vince, 1240-1245).The hospital stay is relatively short. Cruches may be necessary for about three months after surgery. Physical therapy starts in the hospital and is usually continues after release. Knee implants have the same risk of infections as hip implants. Many physicians recommend the same precautions. According to the JADA, the AAOS and the ADA have recommended the use of prophylactic antibiotics only for patients with total joint replacements (not for patients with only pins, screws or plates) and compromised immune systems (Rothwell and Tong, 369).Missing teeth have long been a dilemma for mankind since their existence. The solution to this dilemma has evolved over many years. Dental Implants have changed to become a more acceptable form of treatment for tooth replacement. Dental Implants are biocompatible substitutes for lost natural teeth. Fossil evidence suggests that as early as two thousand years ago, ideas for tooth replacement were implemented. Teeth were replaced by alloplastic o...
