Obesity may hamper some benefits of total joint replacements of the hip

Certain athletes may be prone to developing eating disorders.

Researchers from the University of Florida discovered that obese individuals may not be able to reap all of the benefits of total joint replacements of the hip.

This conclusion is based on a review of 23 previous studies that were conducted between 1965 and 2011. These trials followed total hip replacement patients who had both high and healthy body mass indexes (BMI). Individuals were monitored for between one and 20 years after surgery.

Results showed that regardless of BMI, individuals who had total hip replacements experienced significant pain relief as well as improvements in quality of life, including the level of physical function. However, those who were obese did not benefit as much.

These findings are worrisome in light of the fact that total hip replacement patients these days are younger and more obese.

"Aggressive and sustainable rehabilitation strategies that include physical exercise, psychosocial components and behavior modification may be highly useful in maximizing and maintaining weight loss after total hip replacement. Furthermore, this type of rehabilitation may also reduce the overall health care burden," the researchers wrote in their study, published in the Journal of Orthopaedic Surgery and Research.
