Recovering from MACI surgery

MACI rehabilitation

Following the MACI procedure, your knee will be immobilized and you will need to follow a physician-prescribed rehabilitation program specifically designed for you. Consult with your doctor to determine when you might be able to drive and return to work or other activities.

A support program is available to assist with a smooth recovery. The commitment you make to the rehabilitation program will play a key role in your return to activity.

Recovery time varies greatly as no two patients are alike. Below are general guidelines for typical patient recovery.1*
