Kate E Webster PhD

Professor, La Trobe University
Melbourne, Australia
Director Sport, Exercise and Rehabilitation Research Focus Area


Dr Kate Webster is a Professor in the College of Science, Health and Engineering and Director of the Sport, Exercise and Rehabilitation Research Focus Area at La Trobe University, Melbourne Australia. She obtained a Science degree with Honours from the University of Melbourne and received her PhD in 2000.

Dr Webster’s primary area of research interest is anterior cruciate ligament (ACL) reconstruction.  Her research as it relates to the ACL falls broadly within three categories: 1) knee biomechanics following ACL reconstruction 2) surgical techniques and outcomes and 3) return to sport issues, with a focus on the psychological impact of returning to sport participation. Her current research is focussed on the high ACL re-injury rates in younger athletes and return to sport criteria. She was the lead developer of the ACL-Return to Sport after Injury scale, which has been translated from English to more than 7 languages with further translations underway. A short version of the scale has also recently been published. She has received several awards for her research including 3 best paper of the year awards from the American Journal of Sports Medicine, Orthopeadic Journal of Sports Medicine and Journal of Orthopaedic Research as well as ten best paper awards from national and international organizations and has over 180 scientific publications. She is a current member of the ACL Study Group and past recipient of their Traveling Scientist Fellowship.

Dr Webster also teaches evidence-based practice to undergraduate Allied Health students. She is committed to providing high quality supervision for research students at all levels to foster their development as independent researchers and has supervised many higher degree research students to completion. She is also a research mentor for an orthopaedic fellowship program where she is extremely grateful to collaborate with surgeons at OrthoSport Victoria. Many of her students have received awards for their research projects including the top university research prizes as well as national sports medicine awards.
