Stem cells grow cartilage to fix hips
Scientists are developing a way to treat arthritic hips without extensive surgery to replace them. They’ve programmed stem cells to grow new cartilage on a 3D template shaped like the ball of a hip joint.

What’s more, using gene therapy, they have activated the new cartilage to release anti-inflammatory molecules to fend off a return of arthritis.

The discovery may one day provide an alternative to hip-replacement surgery, particularly in younger patients. Doctors are reluctant to perform such operations in patients younger than 50 because prosthetic joints typically last for less than 20 years. A second joint-replacement surgery to remove a worn prosthetic can destroy bone and put patients at risk for infection....
