Patients do not necessarily lose weight after joint replacement surgery, analysis shows

11 September 2012

There is no proof that patients lose weight after joint replacement surgery is carried out, according to a new analysis.

A review of studies published in the journal Clinical Orthopaedics and Related Research revealed that while doctors may expect patients to lose weight after surgery, this is not the case.

Obesity itself is one of the major risk factors that can lead to the need for a joint replacement.

Due to the fact that a damaged joint can significantly restrict activity levels, people might assume that weight loss would occur after the operation as mobility increases.

In turn, this weight loss could decrease the risk of complications like prosthetic loosening, and cut the chances of the patient having to go under the knife again.

Stuart B Goodman of Stanford University commented, however: “Obese patients frequently tell clinicians that they are overweight because their painful hips or knees limit their physical activities and their capability to ‘burn calories.’

Unfortunately, after a comprehensive analysis of the data, the answer to this important question is still unknown.”
