The number of people who face early knee osteoarthritis symptoms after ACL surgery is staggering, but not much is being done to address it.

A new drug target may offer a way to alleviate the joint breakdown in people with debilitating osteoarthritis.

The same skeletal changes that allowed humans to walk upright make us vulnerable to knee osteoarthritis as we age, human evolutionary biologist says.

Currently in development for implants, a new lab-made cartilage gel may be better than the real thing for relief from stiff, achy knees.

A digital human offers clues on how to use different muscles to ease pressure and protect your knees while you walk.

Some physicians are far more likely to deliver appropriate care than others in the same geographic area or health care system, according to a new study.

New research that eliminated pain in mice with osteoarthritis could one day lead to targeted drug therapies to relieve pain in both dogs and people with OA.

An implant that contains cartilage derived from stem cells eases pain and restores function in dogs with moderate osteoarthritis. Can it work for people?
