MACI Surgery to Restore Your Knee Cartilage

Even small defects in cartilage will continue to get larger without treatment. Damaged knee cartilage can lead to knee swelling, knee pain, knee clicking, and knee popping. Without surgery, the cartilage cannot grow back on its own.

What is MACI?

The MACI procedure (matrix assisted autologous chondrocyte implantation) is a surgical knee cartilage regeneration procedure that uses your own cells to fill in defects in your knee cartilage. 

What steps are involved in knee cartilage surgery?

Knee cartilage restoration surgery using MACI consists of two steps. A small surgery is performed to collect your own cartilage cells. These are multiple at an FDA-approved laboratory and then re-implanted in the knee at a later date.

MACI Knee Cartilage Regeneration Surgery

Use Your Own Cells to Repair Knee Cartilage Damage

Other cartilage repair procedures don't grow back normal articular cartilage. MACI implants your own chondrocytes in the defect, and those chondrocytes then grow normal cartilage to repair the injury.

Can you regrow joint cartilage?

The MACI process allows for surgical repair of the knee joint cartilage. After your own cartilage cells are re-implanted back into your knee, they start growing normal cartilage and fill the defect in the knee.

Can cartilage in the knee be regenerated?

The MACI process for implanting your own cartilage producing cells (chondrocytes) allows for the cartilage to be regenerated after the cells are implanted and mature.

Can damaged knee cartilage repair itself?

Damaged knee cartilage doesn't heal on it's own, and it will gradually get larger over time. This can lead to worse pain and symptoms if untreated.

how long does it take to recover from the maci procedure?

You will wear a knee brace that locks straight, and be limited weight bearing for the first 6-8 weeks after MACI cartilage repair surgery. This will be somewhat dependent on where the lesion was that was treated.

Usually, patients can start walking longer distances for exercise around 3-4 months after MACI procedure.

You can begin light jogging around 7-9 months, and running longer distances around 9-12 months. There are a number of low impact activities that you can also participate in during your recovery, including cycling and swimming.
