3D-Printed Nanofibrillar Scaffolds for Tendon and Ligament Repair

Paul Dalton, Associate Professor, Knight Campus 

Newly developed technologies by Knight Campus faculty have established 3D printing methods that can mechanically mimic soft tissue by incorporating nano- and microscale materials within biomaterial scaffolds. These enabling technologies are the first-of-their-kind in the world and will be used to develop pre-clinical models in service to the biomedical research community, to test new technologies and treatments for tendon and ligament injuries, and hastening translation to patients via clinical trials.

Micron-Scale Devices to Study Brain-Body Communication in Small Nerves

Tim Gardner, Associate Professor and Robert and Leona DeArmond Chair, Knight Campus

The brain and the body are connected through a massive communication network of tiny nerves– information channels that touch every organ in the body, and carry signals to and from the brain. This network is essential to body awareness and peak performance in athletes, as well as injury recovery. Very little is known about the messages passed between brain and body through the peripheral nervous system, due to the extreme technical challenge of recording the signals sent along small nerves. If the language of the peripheral nervous system could be understood, then neuromodulation of small nerves might directly adjust end-organs to achieve optimal state and healing. This project will develop new implantable neural interfaces that can read and write information on the smallest nerves of the body, opening up new sciences of “interoception” and “bioelectric medicine.” The project involves a multi-disciplinary team developing wireless communication with computer circuits smaller than a grain of rice, ultra-high resolution 3D printing, and animal studies to understand how the brain responds to end organ modulation and how the end organs adjust to brain state. Focus on the cardio-vascular system could lead to enhanced athlete training as well as intervention for faster injury recovery.

Development of a Multifunctional Hydrogel Platform for Investigating and Enhancing Muscle Regeneration

Marian Hettiaratchi, Assistant Professor, Knight Campus

Proteins – and the chains of amino acids that make up proteins – are used as bricks and mortar by your body to rebuild damaged or injured muscle fibers. This project will develop: 1) a research platform that will allow us to investigate the impact of injury and treatment on muscle in the laboratory; and 2) a library of therapeutic hydrogels that will accelerate and target the delivery of proteins to muscle for improved repair. Ultimately, our expertise in hydrogel chemistry and protein delivery will allow us to efficiently translate findings from our laboratory muscle model into viable therapeutic strategies for muscle injury.

Developing Traumatic Joint Injury Treatment Strategies Using Therapeutic Delivery and Physical Rehabilitation to Enhance Functional Recovery and Prevent Progression of Post-Traumatic Osteoarthritis

Angela Lin, Senior Research Engineer, Guldberg Lab, Knight Campus

After traumatic joint injury, athletes go through a lengthy and complex return to sport and even with best treatment practices will have compromised long-term joint health. This is in part because standardized approaches to maintaining long term joint health and preventing post-traumatic osteoarthritis are largely nonexistent. This project will develop pre-clinical models, tools, therapies, and characterization techniques and translate these to human clinical treatment and rehabilitation approaches for traumatic joint injuries.

Synovial-Cartilage Organoids for Pre-Clinical Rehabilitation Modeling and Treatment of Knee Trauma

Gabriella Lindberg, Assistant Professor, Knight Campus

Injuries to the knee joint is common in young, active, and athletic individuals, and associated with an increased risk of developing joint pain and reduced quality of life within 3-10 years post injury. To address this clinical challenge, Dr Lindberg’s research is looking at ways of 3D-bioprinting patient's own cells with biomaterials into joint-organoids and pre-clinical rehabilitation models to probe the recovery of acute inflammation and cartilage degradation following joint trauma. Utilizing our expertise in 3D-bioprinting offers improved technical capability to accelerate the development of cellular therapy approaches synergistic with rehabilitation strategies - crucial for high-quality care of young active individuals.

Advanced Suture Sensor Technology for Sport Medicine Applications

Keat Ghee Ong, Professor, Knight Campus

Sutures are an integral part of sports medicine and are commonly used to repair torn muscles and tendons, and close surgical and injury wounds. Recent innovations from faculty at the Knight Campus have enabled the integration of sensors into sutures. These sensorized sutures can greatly improve outcomes of sports injuries by providing biofeedback for therapy, as well as studying and monitoring the injury. However, sensorized sutures often require electronic components that are not inherently biocompatible and/or biodegradable, limiting their application to surface wounds, or forcing later surgery for suture removal. In partnership with UO Athletics and OHSU, we will develop a new biodegradable suture that can monitor conditions at the injury sites and provide new data to study sports injury and recovery.

Training and Rehabilitation Impacts on Cell and Molecular Mechanisms of Skeletal Regeneration

Kryn Stankunas, Associate Professor, Biology

Athletes are susceptible to bone fractures from trauma, stress, and overuse. Rehabilitation improves repair following musculoskeletal damage but restoring performance-adapted function for a safe return to competition can be slow and unpredictable. We are learning how mechanical forces influence genes, cells, and tissues acting at distinct phases of skeletal repair using zebrafish – a spectacular regeneration model developed at the University of Oregon. We will integrate our insights with human studies to pinpoint novel approaches combining regenerative medicine and rehabilitation for optimal injury repair and recovery.
