All-arthroscopic AMIC procedure for repair of cartilage defects of the knee



Bone marrow mesenchymal stem cells were introduced into clinical practice due to their ability to differentiate into many types of cells. Autologous matrix-induced chondrogenesis (AMIC) combines the microfracture method with matrix-based techniques that utilizes a collagen membrane to serve as a scaffold for new bone marrow mesenchymal stem cells, allowing effective reconstruction of even large fragments of a damaged cartilage surface.


All-arthroscopic technique to repair knee cartilage defects using the AMIC technique, which includes the use of a collagen matrix (porcine collagen type I and III) and fibrin glue—technique presentation.


This technical note introduces an all-arthroscopic AMIC technique to reconstruct extensive cartilage defects (without bone defects). The technique may be used for treatment of all location of knee cartilage lesions.
