What is Matrix-induced Autologous Chondrocyte Implantation?

Although stem cells harvested from bone marrow have improved the quality of regenerated cartilage, the regenerated cartilage still lacks the exact properties of the native cartilage.

Matrix-induced autologous chondrocyte implantation (MACI) is a surgical technique recently approved by the FDA that allows physicians to grow a patient’s own cartilage cells and then re-implant them into the knee. This technique has been proven to produce better outcomes than traditional cartilage restoration techniques.

Key Points to Remember

  • MACI uses regenerated cartilage grown from a patient’s own cartilage cells.
  • MACI has been successful in the treatment of cartilage injuries in the knee.
  • Anti-inflammatory medicines should be stopped before and after MACI, as they may interrupt the healing process.
  • It may take 6 – 8 weeks to feel significant pain relief.
  • In general, regenerative and biologic procedures are not yet covered by insurance. You can speak with an ONS insurance specialist at 203-869-1145, ext. 279
