Regenerative Medicine


To promote high-quality clinical research, to provide the public and medical professionals with
educational resources, and to facilitate patient access to regenerative medicine.


Regenerative Orthopaedic and Concussion Research (ROCR) Foundation was founded in 2015 by dedicated clinicians and researchers to expand our knowledge of regenerative medicine and translate those discoveries into vital new treatments for people with degenerative orthopaedic diseases and sports medicine injuries, including concussions.

Our current focus is the study of concussion treatments and the prevention of damage from mild traumatic brain injury. Our goal is to mitigate the deleterious effects of concussions to prevent chronic traumatic encephalopathy (CTE) from developing. Presently, there are no effective treatments for concussions or the chronic symptoms that often accompany them.


We are currently in the investigative phase of performing a clinical trial using regenerative medicine to mitigate the effects of concussion in impact athletes, with the goal of preventing CTE. We are working with CIRM (The California Institute of Regenerative Medicine) to fund the project based upon FDA requirements. The initial phase will focus on providing proof-of-concept data to CIRM and then to the FDA.

Additionally, we are working with a stem cell bank to provide an almost endless supply of homologous (the patients’ own cells) stem cells for treatment of chronic concussive symptoms in former NFL players. We plan to also collaborate with US Navy physicians to offer these treatments to injured veterans.


We look to provide education to the community high schools and establish concussion clinics to evaluate and treat high school athletes. Working directly with the Grossmont Union High School District in a beta program, the clinics will provide education to the parents and students and identify the scholastic impact of concussions. We also plan to help educate physicians about the healing potential of stem cells, if we can prove our theory.


Through clinical research funding, our goal is to provide patient access to these innovative regenerative therapies that are not currently available to the public. We believe our program can revolutionize concussion management and perhaps, change football, soccer, and other high impact/high risk activities.


Our physicians and Clinical Research Organization have developed a protocol to study the use of regenerative medicine to mitigate the effects of concussions in high school athletes. The initial data in animal models prove the concept, and through an IRB safety trial, patients treated with regenerative techniques involving their own stem cells have experienced life-changing improvements.

We know that a randomized, double blinded, placebo-controlled trial is necessary to prove the concept to the FDA, and to ourselves. We feel confident that it will be the first treatment ever to actually help heal the brain injuries sustained by these young people. Current concussion treatment focuses mainly on taking the athlete out of competition and hoping they get better. In other injuries, passive observation is not acceptable treatment, and we would like to change the way concussions are managed.

These necessary studies, unfortunately, are very expensive. ROCR Foundation’s mission is to fund the initial phases of the study in order to reach the point where CIRM will provide the funding for the FDA clinical trial. The initial trial, funded by ROCR, will cost approximately $300,000. The clinical trial to follow will likely cost between 2 and 3 million dollars to make it worthy of FDA approval.
