NanoFx: Innovative strides in Microfracture!

hammer toe surgeryMicrofracture surgery helps repair your painful joints by creating tiny fractures in the underlying bone, specifically, your knee. These small fractures cause new cartilage to form by allowing blood and bone marrow to come through.  This creates new cartilage to help alleviate your joint pain.

The Arthrosurface NanoFx is similar to a Microfracture procedure, by allowing your joints to create new cartilage.  However, the NanoFx is SMALLER* and DEEPER* than a standard microfracture procedure! The NanoFx’s smaller fractures allow more channels in your joints while also going 6mm deeper than a microfracture procedure (The NanoFx has an average depth of 9mm while microfracture only averages 3mm).  The 9mm depth improves access to the targeted marrow cells.  These smaller, deeper “holes” in your bone allow for more blood flow to come through resulting in BETTER (and more) cartilage to form in your joints.
