MACI® (Autologous Cultured Chondrocytes on a Porcine Collagen Membrane)

This repairs damaged articular cartilage in your knee. That’s a type of cartilage that covers and protects the ends of your bones. Damaged articular cartilage will not heal on its own. Repairing it helps you stay active. MACI is a two-step procedure. This means you’ll have two procedures a few weeks apart.
