Healthcare experts recommend a knee replacement surgery if pain and damage in the knee turns into something serious, and drugs and previous therapies do not ease the pain any more. Your medical professional will use X-rays to check the bones and cartilage in your knee to determine whether they are damaged and to ensure that the pain is not coming from somewhere else.
Whilst knee replacement surgery is frequently carried out on men and women who are obese due to the fact they are much more susceptible to knee problems, this type of surgery is not really recommended to people who are severely overweight because replacement joints are much more likely to fail in them.
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 changes become more significant as the body mass index (BMI) increases, in particular the morbidly obese can suffer from increased wound problems, infections and medial collateral ligament avulsion.
Both men and women who are too fat are more inclined to undergo knee replacement surgery, and the fatter they are, the more they are at risk. Males who are overweight are five times more disposed to a knee replacement and females are four times more prone to having it.
Overweight and obese patients in all age groups represent the highest proportion of recipients for knee replacement surgeries. However, although overweight people are credited for most knee replacements, the more overweight they are, the more prolonged the process is before they can have the surgery. The difference in waiting period is not an issue of discrimination against those who are overweight or obese. The orthopaedic surgeons say that knee replacement surgeries are given earlier to those who have lesser risks of developing complications.
Joint replacement has to do with an operation to exchange bone ends in an injured joint. This surgery creates new joint surfaces. The edges of the injured bones of the thigh and lower leg and commonly the knee cap are covered with synthetic planes coated with metal and plastic. Typically, orthopaedic surgeons change the whole facade at the edges of the bones of the thigh and lower leg. 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. Orthopaedic surgeons commonly cement knee joint parts to the bones.
Joint changes caused by osteoarthritis may also stretch and damage the ligaments that connect the thigh bone to the lower leg bone. After the operation, the man-made joint itself and ligaments all over the joint which were left behind typically give sufficient strength thus the injured ligaments are not an issue.
Doctors usually use regional anaesthesia for knee replacement surgery. Although, the choice of anaesthesia depends on your doctor, your overall health, and to some degree, on your own preference.
