A newly developed biomaterial might be able to treat crippling arthritis by prompting the growth of new cartilage, a new animal study suggests.

The bioactive material looks like rubbery goo, but it’s actually a complex biological stew designed to mimic natural cartilage in the body, researchers said.

The biomaterial successfully regenerated high-quality cartilage in the knee ...

The knee develops differently in men and women, with sex-specific distinctions in the joint appearing as early as childhood, a new study finds.

Taking these differences into account among girls could help prevent knee arthritis for women later in life, researchers say.

A blood test could help doctors spot the signs of knee osteoarthritis at least eight years before it shows up on X-rays, a new study claims.

After analyzing the blood of 200 white British women, half diagnosed with knee osteoarthritis and half without, researchers discovered a small number of biomarkers distinguished the women with osteoarthritis from those without it.

"We found we ...

Early-onset arthritis may hit as many as one in every four young people who undergo anterior cruciate ligament (ACL) reconstruction surgeries, new research warns.

The arthritic pain emerges within 6 to 12 months post-surgery, according to Michigan State University (MSU) researchers.

Many of these cases occur in people under 40 and go unrecognized and untreated.

"We're trying...

It's well known that long-acting opioid meds raise the odds for addiction in users -- including folks dealing with pain after an orthopedic surgery.

Now, new research suggests that patients fare just as well if doctors prescribe less risky immediate-release opioids following a knee replacement surgery.
