ACI – Cartilage Transplant
Cartilage Restoration Center of New Jersey

Autologous Chondrocyte Implantation (ACI) is a surgical option to repair an articular cartilage injury in your knee. This procedure is typically used for larger areas of damage or where other cartilage repair procedures have failed. This treatment uses your body’s own cells to regenerate the articular cartilage in your knee.


How is an Autologous Chondrocyte Implantation Done?

A small sample of your articular cartilage is taken arthroscopically and over a five-week period, the biopsied cells are grown in a laboratory until there are approximately 12 million of your cells. The cells are then ready for your doctor to implant. During the implant surgery, your surgeon will:

  • Make an incision to expose and remove the damaged cartilage
  • Placing a biological patch over the damaged area
  • Your new cells will be injected underneath the patch and will form cartilage over time
