Research Summary
Dr. Cosgarea’s research interests involve knee biomechanics, especially the patellofemoral joint. He has worked in collaboration with biomechanical engineer John Elias, Ph.D., on a series of projects that use computational modeling to study patellofemoral realignment surgical techniques. He is also collaborating with Dr. John Carrino using a new imaging technology, dynamic CT scanning, to better analyze biomechanical parameters.
He has been involved in a series of projects exploring posterior knee anatomy. He maintains a database that tracks surgical treatment in patients with pigmented villonodular synovitis. He has studied shoulder range of motion in baseball pitchers by collecting retrospective data from the Baltimore Orioles and prospective data from the Johns Hopkins baseball teams.

Dr. C's surgical skill in repairing my ACL and facilitating the recovery process for my tennis knee injury has been nothing short of exceptional. He is also genuinely caring, which must be a challenging balance to strike when you are also considering the many technical aspects of the injury. He also works with a great PT team - Keelin and Kyla were absolutely instrumental - bringing great patience, care, and most importantly- skill and experience to my recovery process.
