Knee cartilage damage didn’t hold them back. Hear how they overcame knee pain with the help of MACI.

“MACI impacted me in a lot of ways. By resolving my knee pain, it brought me back to doing what I love; running, biking, and just being active with my family and friends.”

Abby is used to being challenged. As a former college athlete, she’s been competing in sports for most of her life. So when knee pain from damaged knee cartilage took her out of the game, there was no way she was going to be content sitting on the sidelines. 

Working with her doctor, Abby chose MACI, a procedure that used her own cells to repair her damaged knee cartilage. With the guidance of her physical therapist, Abby approached her MACI rehab with the same focus and determination she used on the athletic field. 

Hear more about Abby’s story and how MACI helped her get back to living the active life she loves.

Abby approached her MACI rehab one milestone at a time


“Thanks to MACI, I am close to being back in the best shape of my life and each day I’m getting stronger and feeling better.”

Motivation has never been an issue for Chris. Deployed in the Air Force, working out in the gym, or studying for the bar exam, he’s always given it his best. Even when severe knee pain added to the strain of his missions, he was able to push through the pain. But when his doctor explained that his knee cartilage damage was so extensive, it was keeping him from performing at his desired activity level, Chris knew it was time to change tactics.

Unwilling to give up his active life, Chris researched treatment options with the help of his doctor. Together, they chose MACI, a procedure that would use his own cells to repair his damaged knee cartilage, relieving his pain and getting him back to his active life.

“My MACI procedure had a positive impact on my ability to participate in daily activities. I can now spend long hours on my feet at work with confidence and I'm back to enjoying the activities I love.”

Kayla’s always been on the go. From playing competitive soccer in her youth to working as an ER nurse, she’s lived a fast-paced active life. But when knee cartilage damage was preventing her from caring for her patients and enjoying the activities she loved, Kayla decided it was time to take action and care for herself.

After researching her treatment options with the help of her doctor, they decided to move ahead with MACI, a procedure that would use Kayla’s own cells to repair her damaged knee cartilage and provide long-term* results. After her MACI procedure, Kayla’s back to living an active life and working 12-hour shifts in the ER. And she couldn’t be happier about it.
