JMAC Study

New Research Study Investigating Knee Cartilage Repair Device

Microfracture repair is a surgical technique used to repair damaged cartilage by making multiple small holes on the surface of the joint to promote new blood vessels to the region of repair in order to improve the healing process.


Microfracture repair is a long standing and widely used approach for cartilage injuries. 


The purpose of this research study is to determine whether knee cartilage injuries heal better with a microfracture procedure or with a microfracture procedure and a thermo-gel device.

The thermo-gel device is designed to improve the quantity and quality of repaired cartilage tissue, as well as improve joint function and reduce pain from your knee.


The device is currently approved for use by the Therapeutic Goods Administration in Australia and multiple other countries. If you are eligible and choose to join the study, you will have a mixture of standard of care and study visits throughout your rehabilitation.
