Ultrasound of the Knee in Obese Patients With Knee Osteoarthritis; Weight Loss (US-LOSEIT-I)
Ultrasound of the Knee in Obese Patients With Knee Osteoarthritis Following a Significant Weight Loss, Investigating the Impact on Inflammation
This is a substudy to a randomised trial investigating the effect of liraglutide on body weight and pain in overweight or obese patients with knee osteoarthritis (NCT02905864). In the parent trial, patients will be subjected to an 8-week diet intervention phase including a low-calorie diet and dietetic counseling, after which patients will be randomised to receive either liraglutide 3 mg or liraglutide 3 mg placebo as an add-on to dietetic guidance on re-introducing regular foods and a focus on continued motivation to engage in a healthy lifestyle.
This substudy aims to investigate any changes in Ultrasound (US) measures associated with the initial 8-week weight loss intervention.

参加者は、1 日あたり 800 ~ 1,000 kcal の低カロリー処方食を受け取ります。
フォーミュラダイエットは、すぐに使える食事バーとパウダーで構成され、水と混ぜてシェイク、スープ、またはお粥を作ります。
減量プログラムは、標準的な液体エネルギー摂取プロトコルによる完全な食事の置き換えを伴う 8 週間の期間で構成されます。
プログラムの順守を容易にするために、参加者は、栄養士が率いる6〜8人の参加者による毎週の施設ベースのグループセッションにスケジュールされます。
毎日の栄養摂取量の推奨事項が満たされます。
