Medical doctors suggest knee replacement operation when knee pain and loss of function become severe, and drugs and other treatments no longer reduce pain. Your medical professional will use X-rays to check the bones and cartilage in your knee to determine whether they are impaired and to ensure that the pain is not coming from somewhere else.
Even if knee replacement surgery is usually performed on overweight people due to their higher chances of having knee issues, this kind of operation is not suggested to people who are very considerably obese for the reason that joint replacements may not be able to handle their weight.
The short term impact of performing a total knee replacement in an obese patient have shown that obesity was associated with an increased length of hospital stay, discharge to a rehabilitation facility as opposed to home and a higher complication rate.
The alterations turn out to be more important as BMI rises, especially to those who are severely overweight because they may experience more issues with their wound, infections, and medial collateral ligament avulsion.
People of both sexes who are overweight are much more likely to have knee replacement surgery and the more overweight they are, the more likely it is. Men who are obese are five times more likely to have knee replacement surgery and women are four times more likely to have it.
People, who are too fat, regardless of age, stand for the biggest number of beneficiaries of knee replacement surgery. But, even though heavier patients account for most surgeries, the higher a patient’s body mass index, the longer they waited to go under the knife.
Knee Replacement Surgery Wait Times
The discrepancy in wait time for knee replacement surgery is not a factor of bias against overweight or obese people. According to the specialists, the fast track for knee replacement surgeries tends to cater to patients who pose less chance of complications.
Knee replacement involves surgery to replace the ends of bones in a damaged joint. This operation makes new joint planes. The ends of the damaged thigh and lower leg bones and usually the knee cap are capped with artificial surfaces lined with metal and plastic.
Usually, doctors replace the entire surface at the ends of the thigh and lower leg bones.
But, it is gradually more common to change the inner knee planes or the outer knee planes, according to the site of the injury. This is referred to as unicompartmental replacement.
People who are good candidates for unicompartmental surgery have better results with this procedure than with total joint replacement. Doctors usually secure knee joint components to the bones with cement.
Joint variations as result of osteoarthritis may as well extend and injure the ligaments that attach the thigh bone to the bone of the lower leg.
After surgery, the artificial joint itself and the remaining ligaments around the joint usually provide enough stability so that the damaged ligaments are not a problem.
Orthopaedic surgeons usually apply local anaesthesia for knee replacement surgery. However, the choice of anaesthesia depends on your doctor, your overall health, and to some degree, on your own choice.
