Researchers in the United States have developed a promising new technique that might one day enable people to regrow broken bones or diseased joints. However, right now, the technique has only been used in rabbits.

When the animals were given artificial bones, they were able to regrow their own joints complete with cartilage.

The report in "The Lancet" medical journal predicts the research could eventually benefit patients with damaged hips, shoulders or knees.

It may even eliminate the need for metal joint replacements in humans.

Doctors say the regeneration was accomplished using the animals own stem cells.
