Knee Replacement Surgery Overseas from US$7,092
Zimmer NexGen® Complete Knee Solution
Knee replacement surgery is a procedure which replaces a diseased knee joint with artificial material when medications are no longer helpful. The knee is a hinge joint which provides motion at the point where the thigh meets the lower leg. Knee replacement surgery replaces the lower end of the thigh bone with a metal shell. The upper end of the lower leg bone is also removed and replaced with a channeled plastic piece with a metal stem. A plastic "button" may also be added under the kneecap surface depending on the condition of the kneecap portion of the knee joint.

Knee replacement surgery is considered for patients whose knee joints have been damaged by either progressive arthritis, trauma, or other rare destructive diseases of the joint. The most common reason for knee surgery is severe osteoarthritis of the knees.
The knee surgery lasts for about 1½ - 3 hours under general or spinal anesthesia. After the knee surgery, weight bearing on the joint can be expected after 3-5 days.
Risks of knee replacement surgery include blood clots in the legs that can travel to the lungs causing a pulmonary embolism, which can cause shortness of breath, chest pain, and even shock. Other risks include urinary tract infection, nausea and vomiting (usually related to pain medication), chronic knee pain and stiffness, bleeding into the knee joint, nerve damage, blood vessel injury, and infection of the knee which can require re-operation. Furthermore, the risks of anesthesia include potential heart, lung, kidney, and liver damage.
It is important for patients to continue a physical therapy program as an outpatient along with home exercises for optimal outcome of total knee replacement surgery. Patients will be asked to continue exercising the muscles around the replaced joint to prevent contracture and to maintain muscle strength for the purposes of joint stability.
The wound should be protected and observed during the healing process. Patients also should watch for warning signs of infection including abnormal redness, increasing warmth, swelling, or unusual pain. It is important to report any injury to the joint to the doctor immediately.
Future activities are generally limited to those that do not risk injuring the replaced joint. Sports that involve running or contact are avoided, in favor of leisure sports, such as golf, and swimming. Swimming is the ideal form of exercise, since the sport improves muscle strength and endurance without exerting any pressure or stress on the replaced joint.
