Bariatric surgery can improve joint replacement outcomes

31 March 2015

A new study has suggested that bariatric surgery can help improve the outcomes of joint replacements in obese patients. 

Two separate pieces of research from Hospital for Special Surgery (HSS) in New York City has found that weight loss surgery before hip or knee replacement surgery could be a cost-effective option to improve outcomes after hip or knee replacement.

The initial study aimed to look at the costs and benefits of weight loss surgery before knee replacement, while the other analysed the same for hip replacement.

"Up to 50 per cent of hip replacements are performed in obese patients at some institutions," said Dr Emily Dodwell, an orthopedic surgeon at HSS and lead investigator. "Obesity is associated with longer hospital stays, higher overall costs and higher failure rates, necessitating costly revision surgery."

It is known that obesity can impact health, increasing a person's risk of heart disease, diabetes and even some forms of cancer. However, the effect of bariatric surgery was not known. 

Dr Dodwell said the findings indicate that surgical weight loss prior to joint replacement is likely to be a more cost-effective option for healthcare and treating obese patients who are candidates for joint replacement.
