Articular cartilage repair is the improvement of defects of the joint cartilage, either by surgery or biological intervention.

microfracture ACI  
Microfracture - a marrow stimulation technique, where holes are picked through the cartilage base plate, to allow blood and cells to track through into the defect. In ACI - a cell-based therapy, cartilage cells are multiplied in the laboratory and injected into the defect behind a membrane.  


Cartilage repair is part of regenerative medicine

There is a lot of focus currently on regenerative techniques for restoring damaged joint cartilage. Procedures include microfracture, nanofracture, ACI, mosaicplasty, MACI, AMIC, NAMIC, stem cell injections and microfragmented fat injections.
