Piezoelectric material shown to help regrow knee-joint cartilage


By stimulating cells to reproduce, electricity has already been shown to help heal soft tissue injuries. Now, an electricity-producing implantable material likewise appears to boost the regrowth of cartilage in compromised joints.

In a study conducted at the University of Connecticut, a team led by Asst. Prof. Thanh Nguyen and postdoctoral fellow Yang Liu explored the use of a "tissue scaffold" made out of nanofibers of a biodegradable polymer known as poly-L lactic acid (PLLA). It had previously been used to accelerate the healing of broken bones.
