Key takeaways:
- Morbidly obese patients being evaluated for TKA were not able to achieve a BMI loss goal without a formal weight optimization program.
- Bariatric surgery yielded the highest success rate for reducing BMI.
Published results showed most morbidly obese patients being evaluated for total knee arthroplasty were not able to achieve a BMI loss of 5 kg/m2 to 10 kg/m2 without a formal weight optimization program.
Researchers performed a retrospective cohort study of data for 624 patients evaluated for TKA from Jan. 1, 2026, to Dec. 31, 2019, with a mean follow-up of 45 months. Patients were categorized into three groups based on weight loss intervention: no weight loss intervention, nonsurgical weight loss intervention and bariatric surgery. Primary outcome measure was maximum change in BMI.
Overall, 11% of patients pursued TKA during the study period. According to the study, 23.8% of patients who underwent bariatric surgery, 8.6% of patients who received nonsurgical weight loss intervention and 1% of patients who had no intervention had a decrease in BMI of 10 kg/m2 or more. Additionally, 38.8% of patients who underwent bariatric surgery, 27.1% of patients who received nonsurgical weight loss intervention and 6% of patients who had no intervention had a decrease in BMI of 5 kg/m2 or more.
The percent of patients who underwent TKA was 16.3% for the bariatric surgery group, 15.2% for the nonsurgical weight loss intervention group and 6.3% for the group with no weight loss intervention. Among the 125 patients who were originally denied TKA, 80.8% were unable to meet the goal of a BMI loss of 10 kg/m2 without a formal weight optimization program.
