Brian chose to pursue a career in academic orthopaedic sports surgery, and carried out three years of fellowship training. The first year was a research fellowship at the Steadman Philippon Research Institute, where he performed clinical and biomechanics research in knee reconstruction and hip arthroscopy. He then carried out a clinical fellowship at the University of Toronto from 2013 – 2014 also in sports surgery. Finally, he completed two clinical fellowships in Melbourne, Australia; the first was a knee reconstruction fellowship at OSV and the second a fellowship in hip arthroscopy at Hip Arthroscopy Australia.

Mr Haydn Klemm - Research Assistant

Haydn graduated with a Bachelor of Food Science and Nutrition from Deakin University in 2012. He went on to work in the food industry with Mondelez International (formerly Kraft Foods) in their Dairy division. Haydn worked on a wide variety of projects including new product launches and product maintenance.
In 2014 he returned to studies and completed his Honours year. His honours year included a research project, based at Austin Health, studying early nutrition intervention for hip fracture patients. The project required the creation of a database of over 200 patients who had undergone hip fracture surgery during the time periods being studied, as well as statistical analysis of the patient groups and sub-groups. This research has since been published and Haydn presented the findings at the Dietetics Association of Australia conference in 2016.
Haydn started working at OSV in 2015, and commenced his role in the research unit in 2016. He is an integral part of the research team and performs clinical testing of all patients, in addition to managing the TKR patient database. In his spare time Haydn plays rugby, and organises a monthly comic book club.


Ms Tabitha Porter - Research Assistant

Tabitha graduate with a Bachelor of Applied Science (Psychology) (Honours) degree from RMIT University in 2014. Her honours thesis explored the area of injury in sport and how injury severity impacts an individual psychologically. She then went on to work in the research industry with Cancer Council Victoria, actively conducting field observations and data collection. The project she was involved in focused on examining the SunSmart behaviours of individuals utilizing council park facilities. Following this Tabitha worked as a research assistant for Federation University and assisted with a project focusing on eHealth and wellness. This project assessed the effectiveness of the Mindfulness and Physical Activity eHealth program.
Tabitha started working in the research department at OrthoSport Victoria in 2016. She performs data collections for patients who have undergone ACLR and TKR. Tabitha also assists with statistical analysis.
Areas of interest include research and psychology; cross-cultural and sports psychology in particular are areas she hopes to explore in the future. In her down time Tabitha enjoys playing basketball and continuing her training as a black belt in Taekwondo.
