Rationale: Knee osteoarthritis (OA) is a common complication of obesity leading to knee pain and impaired activity of daily living. Weight loss of ≥5% has shown to relieve pain and enhance physical functioning. As part of a clinical non-surgical knee OA management program, a specialized weight loss intervention was established facilitated by clinical dietitians aiming to support patients in achieving clinically relevant weight loss.

Methods: Patients with BMI ≥30 kg/m2 were referred to a 14-week program consisting of an individual consultation followed by six dietitian-lead group-based educational sessions. At first consultation sex, age, weight, height, BMI and waist circumference (WC) was registered. An individual energy requirement was estimated by the Mifflin-St-Jeor equation and a personalized dietary plan, including energy deficit of 500-1000 kcal/d, was provided. Patients were weighed three times during the group sessions, and WC was measured at the end of the program.

Results: 99 patients were referred, 62 patients (69% females) completed the program. Baseline mean (±SD) age 66 years (±9.1), body weight 109.9 kg (±18.5), and median [IQR] BMI 37.8 kg/m² [33.6-41.1]. WC was available in 54 patients, mean WC 121.4 cm (±12.4) and median waist-to-height ratio (WtHR) of 0.72 [0.67-0.75]. After completing the program, weight loss was 4.5 kg (±3.5), corresponding to a total weight loss of 4.2% (±3.1). 90% obtained weight loss and the proportion of patients with weight loss ≥5% was 34%. Reduction in median WC by 3.8 cm [2.0-5.9] and median WtHR by 0.02 [0.01-0.04]. No difference in weight loss or WC between males and females were found.

Conclusion: A group-based dietitian led specialized weight loss intervention provided a weight loss in 90% of patients living with obesity and OA. 34% obtained a clinically relevant weight loss of ≥5%.
