He is an Assistant Professor of Surgery at the University of Ottawa with an active academic and research career. His clinical practice is largely focused on sports medicine, knee and hip arthroscopy, and fracture care. His research portfolio includes multi-disciplinary collaborations, focusing on sports injuries of the knee; primarily ACLs, femoroacetabular impingement and hip morphology, as well as orthopedic trauma. He is the Principal Investigator on over 10 studies at CHEO and numerous more both nationally and internationally. Dr. Carsen is the CHEO RI’s Vice Chair of the Investigator Mentorship Program. He also a member of the RI’s Innovation Committee and Scientific and Advisory Leadership Team.

Areas of Research: Hip, Sports Medicine, Bone Health

Research Projects

  1. Orthopaedic Surgery Pediatric Sports Medicine: Characterizing Practice Patterns and Subspecialization


    Pediatric sports medicine practices are variable and have distinct practice patterns in pediatric, orthopaedic, and adult sports practices. In the current study, most surgeons are less than 10 years into practice, affiliated with academic centers, and have typically completed either 1 or 2 fellowships after residency. Surgeons were most commonly specialized in the knee joint and cared for patients <18 years old.

  2. Management and Outcomes of Clinical Scaphoid Fractures in Children


    Management of clinical scaphoid fractures at our institution was relatively uniform: nearly all patients were immobilized and less than 20% received advanced imaging. Our findings suggest a low but non-zero occult scaphoid fracture rate, discordance in radiologic interpretation, and lack of advanced imaging, providing an avenue for future prospective studies.

  3. Protocol for the systematic review of return‑to‑activity criteria in adolescent patients following an anterior cruciate ligament reconstruction


    Our objective is to systematically examine the literature and identify the criteria used when determining unrestricted RTA following an ACL reconstruction in an adolescent population.

  4. Effect of Osteochondroplasty on Time to Reoperation After Arthroscopic Management of Femoroacetabular Impingement: Analysis of a Randomized Controlled Trial


    This time-to-event analysis with a 27-month follow-up analysis compared the effect of (1) arthroscopic osteochondroplasty with or without labral repair versus (2) arthroscopic lavage with or without labral repair on the time to reoperation in adults aged 18 to 50 years with FAI.

  5. Reliability of a New Arthroscopic Discoid Lateral Meniscus Classification System: A Multicenter Video Analysis


    This new arthroscopic DLM classification system demonstrated moderate to substantial agreement in most diagnostic categories analyzed.
