What is a total knee replacement made of? Total knees are made of metal and plastic. The piece which covers the lower end of the femur (thigh bone) is made of a corrosion-resistant alloy of stainless steel. The opposing surface of the tibia (shin bone) is made of plastic and designed to mate with that of the femur. The undersurface of the patella (knee cap) is replaced with plastic, which moves against the metal of the femoral component. This combination of metal on plastic creates a joint of minimal friction and wear, thus ensuring long life.

How painful is total knee replacement?
As with all forms of surgery, knee replacement is painful, but manageable. The first day following surgery, intramuscular injections of morphine or Demerol are necessary. Thereafter, oral medication such as tablets of Percocet or Vicodin usually suffice. After leaving he hospital, patients may require further pain medication, but less frequently. Within one or two weeks, only aspirin or Motrin are needed.

What are the possible complications?
Although chronic illnesses increase the risk for any surgical patient, knee replacement surgery has a low rate of complications. Fewer than two percent of patients experience knee joint infection or other major difficulties. Blood clots in the leg veins are the most common complication, and can be prevented by medications, special support hose, inflatable leg coverings, and gentle exercises which begin soon after surgery.

What if I can't go home immediately after surgery?
Many individuals lack the appropriate support of a healthy spouse or close family member to allow them to go home immediately from the hospital. For those unable to depend upon family or close friends, an excellent alternative is to use a rehabilitation hospital for one to three weeks. The aim is to regain adequate independence in order to reduce home-care needs to a level which friends or family can easily manage.

Most can be expected to last 10-15 years. If you are overweight, or extremely active, this time may be shortened.
