Important Considerations – Don Wackwitz, M.D.
The Anterior Cruciate Ligament (ACL) is a strong cord like structure running down the center of the knee. It keeps the knee from sliding forward and over rotating. When it is torn it snaps back like a rubber band and the torn ends lose contact with each other. Because the torn ends do not touch, they cannot heal together. The ends are so shredded that the ligament cannot be repaired and therefore it must be reconstructed, that is, replaced with a graft, if we hope to have a stable knee once more.
