This research study is the first of its kind and will allow health care professionals and
researchers to answer many questions about the reasons why anterior cruciate ligament (ACL)
injury leads to knee pain and disability and osteoarthritis. We also hope that this study
will be the beginning of new, more powerful and safer drugs to help patients with ACL
injuries heal sooner and return to sports or daily activities pain free. Study participants
will be recruited from the University of Kentucky and Vanderbilt University.
The purpose of this research is to gather information on how safe and effective Kenalog® is
in alleviating knee pain following ACL rupture.
