This study looked back at 387 people with knee osteoarthritis who received a special gel injection into their knee joint. The goal was to see if the injection could reduce their pain and help them move better in daily life. Researchers measured pain and function before the inject…

This study tested whether repeated injections of an experimental drug called RTX-GRT7039 could safely reduce pain in adults with knee osteoarthritis. About 469 participants who still had significant pain despite standard treatments received either the drug or a placebo injection …

This study tested the safety of a new injection called RTX-GRT7039 for people with moderate to severe knee pain from osteoarthritis. It involved 714 adults whose standard pain treatments weren't working well enough. The main goal was to see how safe and tolerable the injections w…

This study tested whether a 6-week walking program delivered over the phone could help people with arthritis manage their symptoms. Researchers enrolled 267 adults with various forms of arthritis and randomly assigned them to start the program immediately or after a year. The pro…

This study tested three different types of injections made from a patient's own blood platelets to see which works best for jaw arthritis. It involved 42 adults with osteoarthritis of the jaw joint. The goal was to see which injection reduced pain the most and helped people open …

This study tested a single injection called EVI-01 to relieve pain and stiffness from knee osteoarthritis. It involved 120 adults with moderate to severe knee pain to find the most effective and safe dose. Researchers compared two different doses of EVI-01 against an existing act…

This study compared two ways of educating older adults with knee osteoarthritis about their pain. One group received standard education about joint disease, while another learned about the complex biology of pain itself. Researchers measured the body's physical stress responses, …

This study tested whether a nasal spray containing oxytocin, a natural hormone, could safely reduce pain and improve daily function in older adults with knee osteoarthritis. Over 80 participants used the spray or a placebo daily for four weeks. Researchers measured changes in pai…
