What is Obesity?
Obesity
 is almost a pandemic in the current health scenario and it has been 
often established that it leads to a great number of lifestyle disorders
 including diabetes, hypertension, coronary problems and more. Morbidly 
obese people face more complications in their daily movements and have 
been known to undergo Total Knee Replacement surgery
 at younger ages than those with a lower BMI. In recent researches (meta
 analysis, October ’17 issue, Journal of Bone & Joint Surgery) it 
has been established that obese patients who go through Total Knee 
Replacement surgery are almost twice as likely to incur infection post 
surgery and more than 2 times likely to incur deep infection.
The
 obese patients undergoing this procedure are a little more likely to 
later need a second surgery when compared to those that aren’t obese. 
Apart from the risk of infection, other complications post a Total Knee Replacement surgery
 that may arise from obesity include delayed & poor wound healing, 
problems in breathing, formation of blood clots, and even pulmonary 
embolism (blood clot in the lungs). The intent of Total Knee Replacement
 Surgery is help relieve the pain and enable you to live a fuller, more 
active life.
In
 case of obese patients however, the probability of achieving maximum 
mobility and range of motion is particularly low when compared to a 
patient with normal weight. Obesity is also a deterring factor in 
recovery from the surgery which involves controlled movement, and other 
physiotherapeutic exercises. The sheer weight that befalls the implant 
may also lead to its loosening and finally failure of the component 
altogether or a dislocation in the replaced joint. In some of these 
cases there might be a need for a revision surgery where the failed 
implants may need to be replaced with new ones.
Though obesity may be the reason that you need a total knee replacement,
 but in order for the surgery to bear you desirable results for longer 
duration of time, it is important that you check your body weight and 
get it to a healthy BMI.
It
 is important to take control and onus of your life and make some basic 
changes. The first being keeping a check on your caloric intake and the 
second is increasing your physical activity and workout. While it is 
tempting to think that you will work on reducing your weight after the 
surgery when there is lesser pain, but there very few who are able to do
 so post the surgery. It is a good idea to consult your doctor and work 
with his help on reducing your weight to achieve the ideal body weight 
or BMI before going for the procedure. A healthier person on the 
operating table has higher chances of a clean surgery, and a quicker 
recovery with results that last longer.
