Description
When you twist your knee or fall on it, you can tear a stabilizing ligament that connects your thighbone to the shinbone. An anterior cruciate ligament (ACL) unravels like a braided rope when it’s torn and does not heal on its own. Reconstruction surgery can help many people recover their full function after an ACL tear.
