Summary

This trial tests if losing weight before knee surgery and maintaining it afterward can improve recovery for patients with high BMI. The program includes a strict diet before surgery and a regular diet after, along with exercise and counseling. The goal is to see if this approach reduces complications and improves outcomes.

Who is the study for?
This trial is for individuals aged 50-75 with a BMI of 35 to ≤40 kg/m2, scheduled for total knee replacement surgery at KUOrtho and able to participate in remote sessions via Bluetooth-enabled devices. It's not suitable for those outside this age and BMI range or without the required technology.
What is being tested?
The study tests a weight loss program before knee surgery, including a very low-calorie diet and behavior counseling, followed by a maintenance diet after surgery. Participants are randomly assigned to either this intervention or standard care without dietary advice.
What are the potential side effects?
Potential side effects from the weight loss intervention may include fatigue, nutritional deficiencies, mood changes, or muscle loss due to calorie restriction. Increased physical activity could also lead to joint pain or injury if not properly monitored.

Other Research
Common treatments for obesity, such as caloric restriction, increased physical activity, and behavioral counseling, work through distinct but complementary mechanisms. Caloric restriction reduces energy intake, leading to a negative energy balance and weight loss. Increased physical activity boosts energy expenditure, aiding in weight loss and helping to maintain muscle mass. Behavioral counseling addresses the psychological and behavioral factors influencing eating and activity habits, supporting the adoption and maintenance of healthier lifestyle changes. These treatments are vital for obesity patients as they not only facilitate weight loss but also improve overall health, reduce the risk of comorbidities, and enhance the outcomes of surgical interventions like Total Knee Arthroplasty.
