MACI® (autologous cultured chondrocytes on porcine collagen membrane) is made up of your own (autologous) cells that are expanded and placed onto a film that is implanted into the area of the cartilage damage and absorbed back into your own tissue.
MACI is used for the repair of symptomatic cartilage damage of the adult knee.
The amount of MACI applied depends on the size of the cartilage damage. The MACI film is trimmed by your surgeon to match the size and shape of the damage, to ensure the damaged area is completely covered.
Limitations of Use
The safety and long-term clinical benefit of MACI has only been studied in the knee joint.
The safety and effectiveness of MACI have not been proven for patients 55 years old and older.
