Dr. Nissen works in Connecticut Children’s Elite Sports Medicine division, where he specializes in the prevention and care of adolescent sports injuries.  His research interests include a better understanding of the overhead athlete biomechanics and the prevention and treatment of ACL injuries in young student-athletes. He, along with the Center for Motion Analysis and the sports-trained physical therapists at Elite Sports Medicine, is currently studying specific issues regarding overhead athletes and return-to-play issues following ACL reconstruction in young athletes.
