ACL Shrinkage

ACL shrinkage is an exciting new development in ACL reconstruction. When less than 50% of the ACL is torn, it is called a partial tear. Often, the two ends of the ACL are still attached in a partial tear.

In these special circumstances, the ACL can be treated with a laser or radiofrequency probe that cause its fibers to shrink. This "shrinkage" is a result of the collagen in the fibers becoming tighter and stronger.

When stretching or partial tearing of the ACL is suspected, we often recommend this tightening procedure. Many patients prefer this option for treatment for a multitude of reasons. Recovery from shrinkage is much shorter and requires bracing for less time, compared to other ACL repair alternatives. Furthermore, the original ACL is in place, instead of a foreign object or graft. Return to activity is much quicker as well.
