Obesity and Knee Replacement | Dr Sandeep Singh

Knee replacement surgery is a vital solution for individuals struggling with severe knee arthritis and chronic knee pain. However, obesity can impact both the need for and the success of this procedure. Dr. Sandeep Singh, a leading orthopedic doctor in Bhubaneswar, specializes in advanced knee replacement techniques, ensuring the best possible outcomes for his patients. In this blog, our experienced Knee Replacement Surgeon, Dr Sandeep Singh sheds light on the connection between obesity and knee replacement, the potential risks involved, alternative treatment options, and essential recovery strategies for overweight patients.

Obesity is a major risk factor for knee osteoarthritis, which is one of the leading causes of knee replacement surgery. Excess body weight puts immense pressure on the knee joints, leading to faster cartilage deterioration. Some key ways obesity contributes to knee problems include:

• • Increased Joint Load: Every extra pound of body weight adds approximately four pounds of pressure on the knees. Over time, this accelerates wear and tear on the knee joints.
  • Inflammation: Obesity triggers systemic inflammation, which can worsen joint pain and accelerate osteoarthritis progression.
  • Reduced Mobility: Excess weight can limit mobility, leading to muscle weakness and further joint strain.
  • Higher Incidence of Osteoarthritis: Studies suggest that individuals with a high BMI (Body Mass Index) are more likely to develop osteoarthritis at a younger age, increasing the likelihood of needing a knee replacement.

While knee replacement surgery is often necessary for obese patients, it comes with increased risks and challenges:

Surgical Risks:

• • Higher Infection Rates: If you are heavy, you might get infections after surgery. Your blood does not flow as well. Your body cannot fight germs as well. Extra fat makes it hard for your body to heal. Wounds might take longer to close. You might have problems with your wound.
  • Blood Clots: Being heavy makes blood clots more likely. Blood clots can be very bad. They can cause deep vein thrombosis (DVT). They can also cause pulmonary embolism. These are very serious. Doctors will watch you closely. They might give you medicine. They might have you wear special stockings. They will have you move around soon after surgery. This helps stop blood clots.
  • Anesthesia Complications: It can be hard to give medicine to heavy people during surgery. You might have trouble breathing. Surgery might take longer. This is because it is harder to do the surgery. This makes problems with the medicine more likely. Doctors have to be very careful.

Post-Surgical Challenges:

• • Slower Recovery: If you are heavy, you might take longer to heal. Your new knee might have more pressure. It might be hard to do exercises. Exercises are very important. They help you get better
  • Implant Failure: Your new knee might wear out faster. It might break sooner. This is because there is more stress on the knee. You might need another surgery. This surgery can be harder. It can have more risks.
  • Limited Mobility Post-Surgery: It might be hard to do exercises. You might not be able to move as well. You might not have as much energy. You might need more help with exercises. It might take longer to move well again.
