One of theses areas is thermal shrinkage of tissue. With the early favorable results in thermal shrinkage of shoulder capsular laxity, use soon led to treating other joint laxity including anterior cruciate ligaments. The results of thermal shrinkage of ACLs have been mixed with some series reporting excellent outcomes, whereas others were dismal. Further analysis finds the surgical techniques and rehabilitation programs vary widely. Comparison of studies is thus difficult and illustrates that much has yet to be learned in this area. Evidence-based medicine is lacking. In this article, the author's own experiences and opinions concerning thermal shrinkage in treating ACL injuries are reviewed. © 2005 Lippincott Williams & Wilkins, Inc.
