Microfracture is a surgical procedure where a tiny 'pick' is used to spike holes through damaged joint cartilage into the bone below.

 

How does microfracture work?

Microfracture allows migration of marrow cells into the resultant clot, and facilitate new cartilage formation. The technique was first proposed by Dr Richard (Dick) Steadman, and is one of a group of procedures now referred to as 'marrow stimulation techniques'.
