Summit senior accepted into state science fair

Science fair presentation

Summit Country Day School senior Michael Hajjar presents his science research poster at the University of Cincinnati.

A science research poster created by Michael Hajjar, a senior at The Summit Country Day School, will be presented at Ohio's State Science Day on May 11.  

Michael, Symmes Township, presented his poster at the 2019 University of Cincinnati Science and Engineering Expo on March 16 where he received a superior score that promoted the poster to the state fair. 

Through an independent study under the guidance of Jessica Replogle, Ph.D., head of The Summit’s Science Research Institute, Michael has been collaborating with Dr. Samer Hasan at Cincinnati Sports Medicine and Orthopaedic Center on his project since the summer of 2018. His study is called “early outcomes and tendon integrity following arthroscopic repair of retracted large and massive rotator cuff tears augmented with a bio-inductive collagen implant."  

Michael has been comparing the data on patients who have undergone arthroscopic repair of rotator cuff tears with and without a biomaterial tissue scaffold implant. 
 
 “Biomaterials that can promote tissue repair is a promising area of regenerative medicine,” said Dr. Replogle. “His preliminary analysis indicates a positive impact in the quality of life for the group of patients in which the repair was made with the biomaterial although there is more to learn about structural failures that did occur. This is a growing and exciting field of study, and it is was an excellent opportunity for Michael to explore the cross-disciplinary fields of orthopaedics and biomaterials.”
