|The ACL is one of the main stabilizing ligaments of the knee. The ACL helps stabilize the knee by preventing excessive forward movement or rotation of the shin bone (tibia) on the thigh bone (femur). If the ACL is significantly damaged the knee can feel "unstable" or it may "give out". Depending on the type and severity of the injury, other structures in the knee may be damaged in addition to the ACL. There may be injuries to the "shock absorbing" cartilage (menisci), the collateral ligaments (MCL or LCL), the posterior cruciate ligament (PCL) or to the bones of the knee. The degree of injury to the ACL may vary. In some cases the ACL may only be partially torn or in more serious cases the ACL may be completely torn. Unfortunately, the ACL does not have the ability to completely heal once it is injured.

Find a good DR. that will take the time to discuss all your options.
consider the rubber band....take one and stretch it taut. now, take a razor blade and put a little nick in one side. What happens? Now, consider this a moving joint, and its skiing. up, down, up down, tighten, release, tighten....now you hit a bump, a quick motion....what happens to the nick now? it wont take long until it is in two peices.
Ive posted this before and again, not for those who dont have a strong stomach. but the first pictures show the two peices, and the last show a repaired complete ACL....yucky knee surgery pics
most drs. (in my not-an-expert experience) consider a partial tear to be the same as a complete tear, the thing is gone, and useless.
BUT see a dr! one whose done this before! and undeerstands your need for an ACL! [ January 03, 2003, 09:02 AM: Message edited by: LindaA ]
