In this discussion, Professor Henning Bliddal, a renowned researcher in osteoarthritis treatment from Denmark, shares groundbreaking insights on Semaglutide. Originally aimed at weight loss, this drug has shown remarkable ability to alleviate knee pain for osteoarthritis sufferers. Henning reveals how weight loss reduces joint pressure, leading to improved mobility. He discusses the impressive results from clinical trials, practical tips for staying active, and ongoing research needed to ensure long-term benefits for patients.
Semaglutide significantly reduces pain and improves mobility in individuals with knee osteoarthritis through effective weight loss management.
The sustainability of weight loss post-treatment with Semaglutide raises concerns, emphasizing the need for long-term strategies to maintain benefits.

The Impact of Weight Loss on Osteoarthritis
Weight loss has been shown to significantly benefit individuals with osteoarthritis, particularly in the knees and hands. A recent trial demonstrated that a drug facilitating weight loss led to marked improvements in pain and function among participants with symptomatic knee osteoarthritis. The reduction in weight decreases the load exerted on the joints, improving mobility and decreasing discomfort. This relationship underscores the importance of weight management as a non-surgical intervention to alleviate osteoarthritis symptoms.
Efficacy of Semaglutide in Weight Management
Semaglutide, a GLP-1 receptor agonist, has emerged as an effective pharmacological option for weight loss, showing promising results in participants with obesity and osteoarthritis. The study revealed that participants lost an average of 13 kilograms, with pain levels significantly decreasing as their weight reduced. The drug works by inducing satiety, thus helping individuals consume fewer calories. This mechanism highlights the potential of pharmacological intervention in enhancing weight loss efforts beyond traditional methods.
Examining the Study's Methodology and Results
The trial involved over 400 participants who were randomized to receive either semaglutide or a placebo over the course of a year. The primary outcomes measured included a combination of weight loss and improvement in knee pain, both of which were significantly better in the group receiving the drug compared to the placebo group. Participants reported more significant reductions in pain levels, with some experiencing up to a 42-point improvement on a pain scale with a baseline of 70. This substantial effect demonstrates the potential benefits of incorporating GLP-1 agents in osteoarthritis management.
Challenges and Considerations for Long-Term Treatment
Despite the promising results of semaglutide, concerns remain regarding its cost and the sustainability of weight loss after treatment cessation. Participants may experience rebound weight gain, which further complicates the long-term success of this therapeutic approach. There are calls for a comprehensive exit strategy after completing the treatment to maintain weight loss and avoid reverting to unhealthy habits. Such considerations are vital for ensuring that the improvements in pain and function achieved during the trial are maintained in the long run.
This week on the Joint Action podcast, we’re joined by Professor Henning Bliddal, a leading researcher and Director at the Parker Institute in Denmark. Henning Bliddal has spent his career helping people with osteoarthritis live better lives.
In this episode, we talk about a breakthrough study using a medication called Semaglutide. This drug, originally made to help with weight loss, has shown amazing results in easing pain and improving movement for people with knee osteoarthritis. Henning explains how weight loss can take the pressure off your joints and why this is so important for managing knee osteoarthritis.
We cover:
How Semaglutide works and why it helps with knee pain.
The impressive results of the study, including big improvements in pain and function.
Practical tips for staying active and managing weight to reduce joint stress.
What we still need to learn about maintaining long-term benefits.
