Rice bioengineers pioneer techniques for knee repair

... In a third, and perhaps most impressive breakthrough, Athanasiou and Hu used the self-assembly approach to grow the entire articular surface of the distal femur. Each of these unbroken samples were tailored three-dimensionally to fit a specific rabbit femur. "If you told me 10 years ago that we would ...
