Résumé
Despite a paucity of evidence, obesity is frequently cited as an exacerbator of symptoms in foot and ankle arthritis. The aims of the current study were to determine whether simulated weight loss would improve symptoms in obese patients with foot and ankle arthritis. Patients walked on an "anti-gravity" treadmill allowing simulated weight reduction. Pain was recorded at baseline weight and then compared with pain at simulated normal BMI. Simulated reduction to BMI 25 caused a significant reduction in pain. Mean pain scores improved from baseline to BMI 25 by 32% (15.9 points, p=0.04). Paired analysis showed a significant improvement in pain scores (p=0.016) from BMI of 30 to 25. Simulated weight loss from high to normal BMI improved arthritic symptoms. This could be used to power future studies to further investigate the effects of weight loss in foot and ankle patients. Level of evidence Level II - repeated measures cohort study.

BACKGROUND
Despite a paucity of evidence, obesity is frequently cited as an exacerbator of symptoms in foot and ankle arthritis. The aims of the current study were to determine whether simulated weight loss would improve symptoms in obese patients with foot and ankle arthritis.
METHODS
METHODS
Patients walked on an "anti-gravity" treadmill allowing simulated weight reduction. Pain was recorded at baseline weight and then compared with pain at simulated normal BMI.
RESULTS
RESULTS
Simulated reduction to BMI 25 caused a significant reduction in pain. Mean pain scores improved from baseline to BMI 25 by 32% (15.9 points, p=0.04). Paired analysis showed a significant improvement in pain scores (p=0.016) from BMI of 30 to 25.
CONCLUSION
CONCLUSIONS
Simulated weight loss from high to normal BMI improved arthritic symptoms. This could be used to power future studies to further investigate the effects of weight loss in foot and ankle patients. Level of evidence Level II - repeated measures cohort study.
