Do you have a question for one of our presenters? If so, please email Vincenzo Nelli with your question including the Session Title and Presenter name. Vincenzo will forward your question to the presenter for a response. 

Session Title: The Art and Science of Sample Size Estimation: Basic Science and Clinical Considerations

Session Description: Whether you are conducting animal research or plan a large Phase 3 randomized controlled trials, one of the key parts of planning, conducting and reporting research – is sample size! In this session, Statistical Editors of Osteoarthritis and Cartilage will offer their insights into ‘do’s and dont’s’ of sample size estimation for clinical and basic science research, discuss major pitfalls of sample size estimation, describe journal requirements regarding sample size justification and offer a few key practical lessons of how to ‘do it right’.

Session Title: Succeeding in Scientific Publishing: what are our editors looking for?

Session Description: Have you ever wondered why that paper got published and you are struggling to get your manuscript accepted? Wonder no more. The editors of Osteoarthritis and Cartilage and Osteoarthritis and Cartilage Open are going to tell you what constitutes a good manuscript. This will be followed by 30 minutes of questions and answers, so come prepared to ask all those questions you have always wished you could ask a journal editor.

Session Title: Imaging

Session Description: Imaging is the hallmark of osteoarthritis diagnostics and follow-up after interventions. In this OARSI Live Hour, we will hear three highly interesting presentations focusing on compositional and structural osteoarthritic changes in joint tissues - evaluated by MRI - and their association with longitudinal outcomes.

Session Title: Walk this way: Insights into knee osteoarthritis from gait mechanics

Session Description: Knee osteoarthritis is a biomechanically driven disease. In this edition of the OARSI Live Hour, we will learn about changes in gait mechanics after high-tibial osteotomy, advance our understanding of the role of gait mechanics in disease progression, and discuss how people with knee OA respond to perturbations during walking.

Moderators: Deepak Kumar, PT, PhD, OCS, Boston University, Katherine Boyer, PhD University of Massachusetts Amherst

Session Title: Fat metabolism and OA

Session Description: Obesity and metabolic syndrome are now accepted risk factors for osteoarthritis. Although weight increases the mechanical burden on joints, it is becoming clearer that fat tissues are strongly implicated in OA. In this session, three short talks will discuss recent studies describing mechanisms by which fat metabolism can promote OA development.

Session Title: Outcomes of rehabilitation in osteoarthritis

Session Description: Outcome measures for management programs in osteoarthritis rehabilitation will facilitate better comparison between programs in clinical settings and patient populations, and will improve researchers' ability to better evaluate their effects. These outcomes could cover different facets of the patient's symptoms and risk factors, such as pain, stiffness, physical inactivity. Intervention strategies should include a range of intervention strategies, such as patient education, physical activity, exercise, weight loss, and assistive devices. This session will focus on outcomes of management programs in osteoarthritis rehabilitation, including self-management, patient education, and exercise therapy.

Session Title: Assessing outcomes after osteoarthritis pharmacological and surgical interventions

Session Description: Attendees will be able to consider study designs and specific issues concerning outcome measures applied in recent clinical trials with a range of interventions including zoledronic acid, high tibial osteotomy and knee joint replacement for knee OA.

Session Title: Osteoarthritis Genetics and Epigenetics

Session Description: In this OARSI Live session, we will hear from a range of investigators at the forefront of genetic and epigenetic research in osteoarthritis. Join us to hear how this knowledge can help us to elucidate the risk, progression, diagnosis and treatment of the disease.

Session Title: Imaging of osteoarthritis: CT and MRI

Session Description: In this second OARSI Live Hour on Imaging for Spring 2021, we will learn more about imaging and the prevalence of intra-articular mineralizations in osteoarthritis. We will also hear the recent findings on diagnostic performance of region- and layer-specific analysis of T2 relaxation of articular cartilage from MRI.

Session Title: Nuts & Bolts of Writing a Successful Grant: Perspectives from Early Career Investigators

Session Description: In this first of a series of webinars on the topic of grantsmanship and grant writing, the speakers will share their personal experience on what the key conceptual and strategic aspects are for writing grant components like the specific aims page, significance/innovation, and approach. They will provide you with tips and tricks, with plenty of time for questions and discussion during the extended panel discussion at the end of the session. This more general first webinar will be followed by region/country-specific meetings later this year. Topics in the series will include how to write specific components required for fellowship and career development awards and how to tailor grants to strategic priorities for national funding bodies and societies.

Session Title: Cell and Gene Therapy - Regenerative Medicine

Session Description: Articular cartilage has a limited capacity for self-regeneration after injury. Repair of lesions of the articular cartilage is, therefore, a major clinical challenge. In several preclinical and clinical studies, chondrocytes and/or stem cells, delivered in suspension or seeded into biomaterials, have been shown to repair cartilage defects. In this webinar, we will learn about novel translational stem cell-mediated approaches currently under investigation for the repair of articular cartilage and the treatment of osteoarthritis.
