Dr. Trent Guess Strives to Reduce Knee Injuries

Dr. Trent Guess, Associate Professor of Orthopaedic Surgery, and Dr. James Cook, Director of Operations & Research, Mizzou BioJoint Center, received two grants from the Coulter Translational Partnership Program for two projects that both aim to improve knee function.

Dr. Guess and Dr. Cook are collaborating with Dr. James Stannard for the first project, the Mizzou Knee Arthrometer Testing System (MKATS). “Over 750,000 knee ligament injuries occur each year in the United States, reducing knee stability and function,” said Dr. Guess. “Precisely determining the direction and magnitude of the instability (laxity) is vitally important for making a complete and accurate injury diagnosis, determining optimal treatment options, and monitoring recovery for each patient.” MKATS is designed to aid orthopedic surgeons, physical therapists and athletic trainers in delivering affordable and accurate measurement of knee laxity, which Dr. Guess says is a known risk factor for ACL injury.

Kylee Rucinski, Carey Ruekberg and Cory Crecelius from the Missouri Orthopaedic Institute are working with Dr. Guess and Dr. Cook on their second project, the BioJoint Flex. The BioJoint Flex is a non-invasive device that is designed to assist in knee flexion exercises that may be part of pre/post-operative rehabilitation programs and can be used anywhere from physical therapy clinics to the patient’s home. “Current methods for improving knee range of motion can be painful, cause apprehension, be costly, or be ineffective if not done in a controlled and measured manner,” said Dr. Guess. “With the BioJoint Flex, patients are provided the potential to reduce the need for repeat surgery, treat refractory loss of motion (arthrofibrosis), and improve their functional outcomes.”
