Autologous matrix induced chondrocyte stimulation (AMIC)
The AMIC-procedure was published for the first time in 2005 by P. Behrens.
It shall improve the extension of microfracturing to cartilage damages with a diameter of over 2,5 cm.
So, AMIC is based on microfracturing. Due to the application of an additional collagen- or hyaluron membrane on the arising superclot, it is fixated and generally stabilized. Additionally, it improves the filling of the primary defect, which is an important precondition for a good result. Moreover, the application of a collagen structure provides a protected environment in which cells can gain ground, multiply and form repair tissues. The membrane can be attached (fixated) with absorbable pins (picture below) or via glue. This procedure can be performed arthroscopically or via open technique.
