ACL reconstruction using Z-lig, a natural tissue alternative | Patient Story- 9 years post op

Share this post

Marlise tore her Anterior Cruciate Ligament (ACL) in a ski accident. She had an ACL reconstruction using a Z-Lig replacement device, a a natural tissue alternative engineered from porcine tissue (rather than relying on scarce human donor tissue or using tissue from her own body such as a patella tendon.) Less than a year after surgery she reported that her knee had full range of motion, no pain and was totally back to normal. She says "It's now 9 years later and I feel great. I ski, I run, I hike, I can do anything I want."
