Abstract

Purpose

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.

Methods

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.

Conclusion

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.
