How MACI Works
If your doctor has identified you as a candidate for MACI, your doctor may have performed an arthroscopic procedure to help examine and diagnose your knee cartilage damage. The sample of your cartilage cells is used to grow new cells for your MACI implant. These new cells will then create durable repair tissue for your damaged knee cartilage.
This can help:
Reduce Pain*1
Improve function*1
Provide lasting results†1
* In the SUMMIT clinical trial, MACI was shown to offer greater pain relief and improvement in function when compared to microfracture.
† Improvements in pain and function were maintained with MACI at year 5.

Mini Arthrotomy Delivery

Arthroscopic Delivery
Arthroscopic Delivery of MACI
Your doctor may deliver MACI through a mini arthrotomy or through an arthroscopy. If you are a candidate for the minimally invasive arthroscopic delivery of MACI, your doctor will:
- Use a camera through an incision to examine your knee
- Make appropriate incision(s) as needed to deliver the MACI implant.
Arthroscopic delivery of MACI incorporates the advantages of an arthroscopic approach with the long-term durability and established results of MACI. When delivered arthroscopically, MACI knee cartilage repair offers a less invasive surgical incision than knee cartilage treatment options via standard arthrotomy.2 Individual results may vary.
Talk to your doctor to see if you are a candidate for arthroscopic delivery of MACI.
