Microfracture surgery is an articular cartilage repair surgical technique that works by creating tiny fractures in the underlying bone.
This causes new cartilage to develop from a so-called super-clot. Microfracture surgery has gained popularity in sports in recent years; numerous professional athletes including members of the NBA , MLB, NFL and NHL have undergone the procedure.
The surgery is typically lasts 30–90 minutes and is minimally invasive. Microfracture surgery can have a significantly shorter recovery time than a knee replacement.
