About

Dr. Aidin Masoudi is a leading researcher in orthopaedic biomechanics, with a primary focus on shoulder joint mechanics and surgical interventions. His work centers on understanding the intricate relationship between soft tissue structures and joint stability, particularly in the context of posterior shoulder pathology. Dr. Masoudi’s most cited paper, “Posterior Capsular Plication Constrains the Glenohumeral Joint by Drawing the Humeral Head Closer to the Glenoid and Resisting Abduction” (2015, 15 citations), provides critical insights into how surgical tightening of the posterior capsule alters joint kinematics. This study demonstrates that plication not only reduces excessive translation but also shifts the humeral head medially, effectively resisting abduction—a finding with direct implications for treating recurrent shoulder instability. By quantifying these biomechanical changes, Dr. Masoudi’s work helps surgeons refine techniques to improve patient outcomes. His research addresses a pressing clinical need, given that shoulder pain affects 30–50% of Americans annually, with 54% experiencing persistent symptoms after three years. Through his rigorous experimental approach, Dr. Masoudi bridges the gap between basic science and clinical practice, offering evidence-based guidance for managing complex shoulder disorders.
