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

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

A new technique to regrow cartilage could one day help people avoid arthritis before things get too bad, researchers say.

The new hydrogel is strong enough to stand up to stretching and squishing like real knee cartilage. A quarter-sized disc can handle a 100-pound kettlebell.

Research with a baby duckbilled dinosaur "adds to the growing body of evidence that these tissues, cells, and nuclear material can persist for millions—even tens of millions—of years."

Greater understanding of the "'salamander-like' regenerative capacity" in human cartilage could lead to better treatments for osteoarthritis.

Scientists have tried developing scaffolds from plastics and textiles to repair a torn meniscus in the knee. Now, an organic model shows promise in the lab.

A new 3D-printed scaffold may one day help heal bone and cartilage injuries, common to athletes' knees, ankles, and elbows.

A new way to deliver growth factors for cartilage regeneration could be useful for treating osteoarthritis.

Researchers hunting for valuable skeletal stem cells have found them in special tissue called the "resting zone," but don't assume they're slacking off.
