2021 OARSI Discussion Groups Events

This year, the OARSI Discussion Groups will meet virtually either the week before or the week after the Virtual World Congress. Please see below for the Discussion Group dates and registration links.


Osteoarthritis Rehabilitation Discussion Group: Journal Club
Date and Time: Wednesday, April 7, 2021, at 4:00 pm EDT
Event Description: The START trial by Prof Stephen Messier and colleagues, comparing high vs low-intensity strength training and attention control in people with knee OA, was recently published in the prestigious Journal of the American Medical Association (JAMA). The study has generated much debate and discussion online with key issues it raises being: 1) why was there no difference between high vs low-intensity strength training; 2) what are the mechanism of effects of exercise; 3) what is the appropriate control group in rehabilitation trials, and 4) what are the implications for clinical practice. Join us to hear from Prof Messier and an international panel (Prof Marius Henriksen, Prof Ewa Roos, Prof Haxby Abbott, Prof Elena Losina, Dr Greg Lehman) as they discuss the study and have an opportunity to put forward your questions for the panel to address.


Osteoarthritis Rehabilitation Discussion Group
Date and Time: Tuesday, April 27, 2021, at 4:00 pm EDT
Event Description: This session will provide an update on the group's activities as well as presentations about digital technology for OA rehabilitation selected from the OARSI conference poster presenters.


Pain in Osteoarthritis Discussion Group
Date and Time: Tuesday, May 4, 2021 at 11 am EDT
Event Description: The Pain in Osteoarthritis Discussion Group will address the following questions.

  1. ​Are there sufficient differences in the aetiology of OA pain and structural pathology to formulate distinct patient phenotypes and treatment plans?
  2. What steps are needed for improving the evaluation of promising preclinical therapies in animal models for translation to clinical trials?



Joint Effort Initiative Discussion Group
Date and Time: Tuesday, May 4, 2021, at 4:00 pm EDT
Event Description: The Joint Effort Initiative Discussion Group meeting will present what is coming up for the Joint Effort in the areas of outcomes, implementation, and education in 2021. It will explore international gaps in the implementation of osteoarthritis management programs, and discuss the next priorities for the group.


International Hand Osteoarthritis Consortium Discussion Group
Date and Time: Wednesday, May 5, 2021 at 10:30 am EDT
Event Description: The Hand OA Discussion Group event will feature three short presentations followed by a Q&A session, and open floor discussion. In addition, attendees will vote online to address important and topical aspects of hand osteoarthritis.


Imaging Discussion Group
Date and Time: Wednesday, May 5, 2021 at 4:00 pm EDT
Event Description: This year’s Imaging Discussion Group Meeting will focus on early osteoarthritis. Two keynote speakers will introduce the subject and provide pertinent information to initiate a productive discussion. Following the keynote presentations, attendees will break out into one of four different breakout rooms according to their areas of expertise and interest. The breakout sessions will be followed by a summary from each breakout session leader. When registering please indication which breakout session you would like to join. 



International Foot and Ankle Osteoarthritis Consortium Discussion Group
Date and Time: Thursday, May 6, 2021 at 7:00 am EDT
Event Description: The aim of this discussion group meeting is to bring together international experts in the field to discuss the current evidence around foot and ankle osteoarthritis, and to start a discussion around a research agenda for the future. In doing so, we hope to provide a strategic framework for future work by the consortium members. At the meeting, we will divide into 5 breakout rooms where evidence relating to (i) epidemiology, (ii) diagnosis, (iii) burden, (iv) outcome assessment, and (v) treatment will be discussed and additional suggestions regarding the research agenda items summarised. Our plan is to follow up on the research agenda items after the meeting using a simple polling platform for voting on priorities.

OA Prevention related to Sport, Exercise, and Physical Activity Discussion Group
Date and Time: Thursday, May 6, 2021 at 3:00 pm EDT
Event Description: This discussion group session will highlight short talks summarizing four relevant papers published that are relevant to Osteoarthritis Prevention related to Sport, Exercise, and Physical Activity. These papers will highlight four identified research topics including:

  • Breakout Room 1: The effectiveness of primary injury prevention strategies (Carolyn Emery)
  • Breakout Room 2: Targets informing the prevention of post-traumatic osteoarthritis (Brooke Patterson)
  • Breakout Room 3: The effectiveness of interventions in reducing the risk of the development and progressions of OA (Bjornar Berg)
  • Breakout Room 4: The barriers and facilitators to a comprehensive approach to primary prevention of joint injury and secondary prevention of osteoarthritis (Celeste Dix)

The panel discussion and break-out room to follow will include one author from each of the above papers and will be hosted by our discussion group organization committee members.



Spinal Osteoarthritis Discussion Group
Date and Time: Monday, May 10, 2021 at 4:30 EDT 
Event Description: The Discussion Group will follow on the actions and outcomes of our Workshops presented at OARSI in Toronto, 2019 and the Low Back Pain Research Forum in Quebec 2019, as well as the results of a Delphi exercise on the definition of spinal OA for clinical practice and research purposes. We will also discuss the next steps into implementing these results in clinical practice and research.
