These diabetes drugs might actually heal worn-down joints in arthritis, not just reduce pain, by working directly on the joint tissue in ways that matter for people.

Semaglutide ameliorates osteoarthritis progression through a weight loss-independent metabolic restoration mechanism.
The study tested semaglutide, a type of GLP-1 drug, and found it helped repair joint damage in mice and showed promise in people, not just by helping weight loss but by directly healing joint tissue.
The potential role of GLP‐1 receptor agonists in osteoarthritis
The study looks at the same drugs mentioned in the claim and finds they help with weight loss and joint pain, and might reduce joint damage through anti-inflammatory effects, but it doesn’t prove they can actually reverse joint damage in people.

Community contributions welcome
The study looked at people taking GLP-1RAs and found they were more likely to develop hip and knee arthritis over time, not less. This goes against the idea that these drugs help heal joints.
