Boosting ACL Healing with a Special Scaffold

Anterior cruciate ligament (ACL) repairs can be tricky because the body's own fluids can eat away at the new tissue, causing it to fail and make the joint worse. Researchers found a way to protect the new ACL tissue by creating a strong, long-lasting shield. They mixed collagen and polyvinyl alcohol to make this shield, and added some special blood called platelet-rich plasma (PRP) to help the tissue heal better.The shield is made by freezing and thawing, which strengthens it and makes it last longer. In tests, it could handle a lot of force before breaking. When the shield is used in rabbits, it helps the ACL heal by making new blood vessels and helping the body's own cells repair the tissue. Plus, it keeps the other parts of the joint healthy. This new shield could be a big help for people with ACL injuries.
