The AI and deep/machine learning technologies have been gaining more and more attentions in the biomedical research communities. In many areas, image based deep/machine learning technology has shown significant successes in solving challenging problems that would otherwise be difficult or impossible for the existing technologies to tackle. For example, AI based diagnostic tools of skin cancers have achieved unprecedented success in clinical diagnosis of the diseases. However, researchers in the field of orthopaedics are a little behind our colleagues, which is manifested by the fact that out of nearly three thousands ORS abstracts in 2020, only fifteen were related to AI and machine learning. The major reason for this paucity of AI technologies in orthopaedic research and practices is largely due to the lack of understanding of the technologies and lack of direct interactions with AI/machine learning experts. This timely workshop will address the urgent need of the orthopaedic research community by introducing the basic concepts and techniques of AI and deep/machine learning to ORS members. We expect that the powerful AI tools will bring in paradigm shifting changes in both basic orthopaedic research and clinical practices.

Although videoradiography and computed tomography (CT) approaches are being utilized to study biomechanics of the joints and implants, current approaches remain time-consuming and expensive. This workshop is the first step toward the goal of assembling a consortium of investigators to discuss the current challenges and to critique a newly developed open-source software approach to address these challenges.

Machine learning (ML) is the study of computer algorithms that can learn complex relationships or patterns from empirical data and make accurate decisions. Within musculoskeletal medicine, ML has proven influential in applications including understanding biomechanics, orthopaedic implant design, and, prediction of progression of osteoarthritis. There is a need to understand what problems in medicine might benefit from such learning approaches, identify what obstacles to changing the current practice of medicine through statistical learning approaches, and discuss how these might be overcome.

Developmental dysplasia of the hip (DDH) is characterized by an insufficient acetabular coverage around the femoral head and remains an ongoing challenge in orthopaedics. The pathomechanical process is associated with hip instability, ligament laxity, and sometimes frank dislocation; which result in adverse joint loading, early hip degeneration, and an increasing number of young adult hip surgeries. We know that dysplasia causes substantial differences in joint function, mobility, and stability. The orthopaedic biomechanics community has been committed to examining the pathomechanisms through various multidisciplinary approaches and biomechanics research methods (e.g., in vivo, in silico, in vitro). However, with the large spectrum of methods, it is unclear how we can progress and link each individual approach to validate our results, translate findings, and establish the much-needed biomechanical metrics and testing standards to refine our understanding of hip dysplasia and instability mechanics.

The interosseous ligament (IOL) is an important soft tissue stabilizer of the forearm and is responsible for resistance to shear stress. This workshop will feature a  review of IOL anatomy with a focus on how to improve surgical outcomes through an understanding of IOL biomechanics. This info will be useful in implant development and will help us understand how to stabilize soft-tissue injuries.

Portable ultrasound technology has the potential to revolutionize access to medical imaging, changing future approaches to diagnosing, monitoring, and treating disease. However, relatively few clinicians and scientists are aware of the potential benefits of this technology if applied in musculoskeletal disease. This workshop will answer three questions: 1) Why should portable ultrasound be used in musculoskeletal disease? 2) For what musculoskeletal illnesses is portable ultrasonography applicable? and 3) how should we use this technology in musculoskeletal diagnosis and treatment?  This workshop is designed to create awareness about the use of portable ultrasound among clinicians, engineers, and scientists as an important first step in new research initiatives using this technology, and in making musculoskeletal medical imaging accessible to everyone.

Exosomes, a class of extracellular vesicles that range from 40-120 nm in size produced from almost any cell types, has been studied for their highly regenerative potentials. As the novel therapeutics, it is critical to understand the mechanisms of exosome pathways and clinical application potentials in the orthopedic field.

One of the main causes of poor fracture healing is infection. Unfortunately, bone regeneration and infection research are typically approached independently and viewed as two different disciplines. Here we aim to bring these two groups together in an educational workshop to promote research into the basic and translational science that will address the clinical need of delayed fracture healing due to infection.

Currently, no other society or organization exists that so tightly integrates scientist in multiple fields with research clinicians that can run the translational trials. We believe there is an opportunity to create networks motivated to develop clinical trial that advance the novel basic science presented at ORS. This workshop aims to provide insight and tools to researchers that will improve translational research design through didactic presentation from clinician and industry scientists with experience in multi-center clinical trials. This workshop hopes to be a first step in establishing ORS as the premier society for the de novo establishment of collaborative multi-center clinical trials and respected home for presentation of prospective clinical studies in musculoskeletal research.

Additive manufacturing (AM, also known as 3D printing) is a new area with the potential of wide applications in medical devices and implants in orthopedics. However, unless one is a practitioner using these processes, a thorough understanding of the fundamentals of 3D printing, different manufacturing methods, and advantages in clinical application and potential drawbacks, is hard to come by. We will focus on educating the audience on the various aspects of 3D printing technology, including implant safety and characterization and will address the knowledge gap on material characterization and what is possible with newer design and manufacturing methods available today.
