Strong Opposition

People with knee arthritis and diabetes who take GLP-1 drugs like Ozempic seem to need knee surgery less often — 1.7% of them did over 6 years, compared to 5.9% who didn’t take the drugs — and some of this benefit comes from losing weight.

Effect of glucagon-like peptide-1 receptor agonists in osteoarthritis: A systematic review of pre-clinical and human studies

Systematic Review
Animal
2025 Mar

The study looks at whether GLP-1 drugs might help with knee arthritis, but it doesn’t look at whether they reduce the need for knee surgery, so it can’t confirm the claim.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Similar Assertions

People with knee arthritis and type 2 diabetes who take GLP-1 drugs (like Ozempic) may be less likely to need knee surgery—only 1.7% did, compared to 5.9% who didn’t take the drugs, over about 8 years.

For people with knee arthritis and type 2 diabetes, taking GLP-1 drugs (like Ozempic) may lower the chance of needing knee surgery — and about one-third of that benefit comes from losing weight, not just from better blood sugar control.

If you're obese but don't have diabetes, taking GLP-1 drugs like Ozempic for five years doesn't seem to raise your risk of joint problems like arthritis or needing joint surgery — so if joint issues show up in people with diabetes on these drugs, it might be because of their diabetes, not the drug itself.

People with knee arthritis and type 2 diabetes who take GLP-1 drugs like Ozempic might lose knee cartilage more slowly, which could help delay joint damage.

Some diabetes drugs might help people with knee or joint pain from osteoarthritis feel better and move easier, especially if they also have type 2 diabetes or are overweight.
