Knee Replacement with Obesity
If you need to get knee replacement surgery but
your weight is higher than the standard range,
your knee surgeon may advice you to reduce
weight. Various studies showed that even if the
patient doesnt feel any difficulty with
increased weight, patient with BMI higher than 40
are more likely to face some complications
related to surgery, high cost of surgery and
post-surgery recovery than those with normal
BMI. Many of you must be having confusions like
what is BMI and how it affects the surgery? BMI
refers to Body Mass Index, it is measure of body
fat based on the weight and height of the
individual. BMI is measured by applying the
following formula BMI (kg/m2) mass (kg) /
height2 (m) Normal Range of BMI for an average
adult- 18 to 24

Abnormal BMI range Below 18 is underweight 25
to 29 is overweight Above 29 is obesity Relation
of knee replacement with obesity According to
various studies, around 75 of patients under the
age of 60 year need knee replacement surgery due
to obesity. Another study showed that for knee
replacement surgery, obese patients are more
likely to get knee replacement surgery than
normal population i.e. around 10-15 years
earlier. Complications of Knee replacement
surgery During Surgery During surgery, it
becomes more difficult for a patient with obesity
to get administered with anaesthesia due to the
patient's body shape and excess fat. Most common
challenges for an anaesthesiologist are as

• Locating veins foradministration of general
  anaesthesia and important medications,
• Oxygen and airflow are monitoring
• Position of the needle for delivering nerve
  blocks and other regional anaesthesia blocks.

Patients with obesity require more care and
specialised instruments to reach the site of
surgery through fat. During operation it takes
longer time and have greater risks.

  and BMI, obese patients are more at risk of
  post-surgical complications, such as
• Infection
• Poor or delayed wound healing
• Breathing issues
