Daniel Whelan




Dr. Daniel Whelan is involved in several multicentre clinical trials in orthopaedic sport medicine, including an ongoing investigation on ACL reconstruction with hamstring tendon grafts. In partnership with the Pan-Am Sports Medicine Clinic in Winnipeg, Dr. Whelan is comparing the traditional trans-tibial technique for creating the femoral tunnel with a more novel ‘anatomic’ method utilizing an accessory anteromedial portal. They plan to begin a randomized investigation comparing early range of motion following multiligament reconstruction of the knee versus the traditional mandatory four weeks of immobilization. Last fall, Dr. Whelan was awarded the Sandy Kirkley Grant by the American Orthopedic Society for Sport Medicine to begin a trial on shoulder dislocations at St. Michael’s Hospital. This randomized investigation will compare two techniques for emergently immobilizing shoulders following primary dislocations.

Please note that Dr. Whelan is not accepting any summer students.
