Assistant Professor of Orthopaedic Surgery

From the December issue: Simulation of Anterior Cruciate Ligament Reconstruction in a Dry Model
Podcast: Listen to Dr. Dwyer discuss his article in the December issue.


Dr. Tim Dwyer is an orthopaedic surgeon at the University of Toronto, based at Women’s College Hospital and Mt. Sinai Hospital.  Dr. Dwyer graduated from the University of Queensland Medical School in 1998, and undertook orthopaedic training in Queensland, Australia, and London, England. Following fellowship training in sports medicine and shoulder surgery, he settled in Toronto, with a focus on open and arthroscopic surgery of the knee and shoulder.

Dr. Tim Dwyer’s primary research focus is on the assessment of surgical competence, the basis of his PhD thesis.  Tim is interested in assessment tools that can be used to establish competency in both clinical reasoning and the performance of technical procedures in residents, fellows, and practicing surgeons. Much of this work uses simulation, and is held in state of the art facilities such as the Women’s College Hospital’s Arthroscopic Simulation Laboratory, as well as the Surgical Skills Centre at Mt. Sinai Hospital.

Dr. Dwyer is also involved in clinical trials related to research in sports medicine, especially in regards to knee and shoulder surgery.  These included ongoing randomized clinical trials addressing massive rotator cuff defects, shoulder arthritis, and ACL reconstruction, as well as basic science projects that focus on complex shoulder instability, and the reliability of measurement as it pertains to clinical practice.
