According to published results, most obese patients undergoing total knee replacement surgery were unable to lose between 5 and 10 kilograms without an official weight loss program.
Researchers conducted a retrospective cohort of 624 patients who were evaluated for TKA between Jan. 1, 2026 and Dec. 31, 2019. The average follow-up was 45 months. The researchers divided the patients into three groups, based upon their weight loss interventions. These were: No weight loss intervention; Nonsurgical Weight Loss Intervention and Bariatric Surgery. Primary outcome was the change in BMI.
