Colorado State University Clinical Trials

Thank you for your interest in Colorado State University's Clinical Trials. Knee ligament or ACL-tears (in dogs called canine cruciate ligament disease or rupture - CCLD/CCLR) are a common problem in people and animals. Many surgical and non-surgical treatment options are available, however, Tibial Plateau Leveling Osteotomy (TPLO) is one of the most reliable and effective techniques to restore stifle stability. Surgery is generally recommended for young, active dogs. More info about the disease can be found here (external link to the CCLD-page of our website).

At CSU, we are evaluating a dietary supplement (kibbles) for its efficacy in aiding post-operative recovery. This study is designed for dogs suffering from CCLD, weighing between 10-50kg, 1-12 years of age that are otherwise healthy. The study uses ultrasound to determine muscle recovery after TPLO. You will be required to return to the CSU-VTH 2, 4, 6 and 8 weeks after surgery.

Incentives of the study include free X-rays at 6 and 8 weeks as well as an $850 incentive (reimbursement after completion of the study). To find out more details about the study please visit our clinical trials website at

To determine whether your dog might be a candidate for our ongoing clinical trial please fill out our short survey. It should take about 5 minutes to complete the survey. Be sure to leave your contact information in order to be contacted regarding the next step to enrollment.
