Introducing MACI® Cartilage Repair

Repair knee cartilage defects using your own cells.

MACI, part of our Joint Restoration and Preservation category of treatment, is an ACI (autologous chondrocyte implantation ) procedure that repairs cartilage using the
patient’s own cells
. This minimally invasive procedure provides reduced pain
and improvement in function.*

How does MACI work?

A sample of your cartilage cells (chondrocytes) is sent to a laboratory and embedded on
a special collagen membrane which your doctor then implants into your knee.
The cartilage cells regenerate, forming a repair tissue that is able to fill the cartilage
defect. View the video and illustrated steps below.




MACI Step 1: Cartilage Biopsy Taken

STEP 1: During your arthroscopy, a procedure to look inside your knee, your surgeon
will take 2 to 3 pieces of healthy knee cartilage, each about the size of a Tic Tac®, and
send them to the MACI state-of-the-art, FDA-licensed facility.

MACI Step 2: Biopsy Processed

STEP 2: At the facility, your cartilage cells will be treated to help them expand and multiply. Your expanded cells are then placed onto a special membrane and delivered to your surgeon for your procedure.

MACI Step 3: Cells Implanted

STEP 3: The membrane will be customized to match the size and shape of your cartilage defect before it is affixed to the damaged area of your knee cartilage.

MACI Step 4: Regeneration Begins

STEP 4: Once implanted into the damaged area, your cells detach from the membrane, combine with proteins in your knee cartilage, and form a durable repair tissue. This
durable repair tissue continues to mature over time, filling your defect to regenerate the damaged cartilage.

MACI Step 5: Rehabilitation - The Final Step

STEP 5: You will begin a physician-prescribed rehabilitation program specifically designed for you. As you progress through the program, you should begin to experience restored knee function, helping you get back to your active lifestyle.
