Many people around the world suffer from osteoarthritis, especially as they get older. It’s a condition where the joints, like knees and hips, become painful and stiff.
This happens because the smooth cushion between the bones, called cartilage, wears down over time. When the bones rub against each other, it causes swelling, pain, and difficulty moving.
In serious cases, people may need to have surgery to replace the damaged joint, which is expensive and takes a long time to recover from.
Now, scientists have found something that could bring new hope. A medicine called colchicine, which is already used to treat other health problems like gout and heart inflammation, may help people with osteoarthritis. The exciting part is that this medicine could lower the number of people needing joint replacement surgery.
Colchicine is a drug that reduces swelling and inflammation in the body. Inflammation is one of the main reasons why cartilage breaks down in people with osteoarthritis. By lowering the inflammation, colchicine may protect the joints and slow down the damage.
A team of researchers from the Netherlands and Australia tested this idea. They worked with 43 medical centers and studied over 5,500 people between the ages of 35 and 82.
Half of the people in the study took a tiny amount of colchicine (just 0.5 milligrams) every day. The other half took a placebo, which is a fake pill that does not do anything. They followed these people for about two and a half years.
The results were very interesting. Only 2.5% of the people who took colchicine needed knee or hip surgery, while 3.5% of the people who took the fake pill needed surgery. That may seem like a small difference, but it’s still important. If millions of people take the drug, this small drop could mean thousands of people avoid surgery.
The benefit seemed even stronger in men, but the researchers said they didn’t have enough women in the study to say for sure if it works just as well for them. More research is needed with more women included to better understand the results.
It’s important to know that doctors are not ready to start giving colchicine to all patients with osteoarthritis just yet. Scientists still need to make sure the drug is safe to take for a long time. Medicines can have side effects, especially if people take them every day for years. So more studies will be needed to answer those questions.
Still, the idea that a simple, cheap, and widely available pill could reduce the need for joint surgery is very promising. For people living with pain from osteoarthritis, this could be life-changing. It may help them move better, feel less pain, and avoid difficult surgery.
This study was published in the journal Annals of Internal Medicine. It shows that sometimes, old drugs can have new uses. If future studies confirm these results, doctors may one day be able to offer a daily pill to help protect joints and delay serious surgery.
If you care about bone health, please read studies that plant-based diets can harm your bone health without these nutrients, and this bone problem may strongly increase COVID-19 death risk.
