Overview
Brief Summary
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.

Outcomes
Primary Outcomes
Change in the degree of inflammation in the knee-joint (Greyscale-score)
Time Frame: Week -8 to 0
Change will be assessed by grey-scale ultrasound in the suprapatellar, the medial, and the lateral recess´ (sum-score (0-9), derived from these three positions)
Secondary Outcomes
- Change in knee-joint effusion(Week -8 to 0)
- Change in the degree of inflammation in the knee-joint (Greyscale-size)(Week -8 to 0)
- Change in the degree of inflammation in the knee-joint (Doppler-score)(Week -8 to 0)
