A knee replacement is a surgical procedure in which artificial components replace a knee joint that has been severely damaged by arthritis or injury. According to the American Academy of Orthopedic Surgeons (AAOS), this surgery provides a significant improvement in the ability to perform common activities of daily living in more than 90 percent of patients. Although your orthopedist will properly evaluate your risks, be aware of additional risks if you are elderly.
Falls
Falls are a major risk in the elderly population after knee replacement. Elderly people may have impaired vision, decreased balance sense or weakness that may increase the risk of a fall. An early fall after surgery can severely damage the knee replacement and may result in additional complications or further surgery. According to the AAOS, stairs are a hazard during your recovery period. The AAOS further advises the use of a cane, crutches, a walker or hand rails until you recover. Be sure to use extreme caution when beginning to walk. Make sure hallways are clear of objects that may cause you to fall. Allow your doctor to evaluate your new knee replacement if you experience a fall.
Infection
A 2008 article in the Archives of Internal Medicine, reports that infection is a risk associated with knee replacement surgery in the elderly. Infection is a risk during any surgery, although your doctor should take appropriate measures to prevent this. However, in elderly this risk may be higher due to a weakened immune system. Look for redness, warmth, swelling, excessive pain and drainage from the wound site if you suspect an infection. Alert your doctor if you experience any of these signs.
Blood Clot
A blood clot that can lead to severe respiratory distress is a possible complication in the elderly, according to the Archives of Internal Medicine. Blood clots may form because of the damage to blood vessels during surgery. These clots that form in the leg veins may dislodge and travel to the lungs, and cause difficulty breathing that could lead to death. Therefore, it's important to be aware of signs of a blood clot in your leg. This includes redness, warmth, swelling and pain in your leg that's distant from your surgical wound. Seek immediate medical attention if you have these signs of a blood clot.
