About

Dr. Lianxu Chen is a leading orthopedic researcher whose work centers on knee biomechanics and meniscal pathology, with a particular focus on how meniscal injuries compromise joint stability. In his highly cited 2014 study, "The effect of medial meniscal horn injury on knee stability" (23 citations), Dr. Chen conducted a meticulous porcine model investigation to differentiate the biomechanical consequences of anterior versus posterior horn damage of the medial meniscus. By systematically testing knees in intact and injured states, he demonstrated that posterior horn lesions more severely destabilize the knee during rotational and translational loads. This foundational work has been instrumental in guiding clinical decision-making for meniscal repair versus partial meniscectomy, emphasizing the critical role of the posterior horn in maintaining joint function. Dr. Chen’s research is widely referenced by surgeons and sports medicine specialists, and his findings have directly informed surgical strategies aimed at preserving meniscal integrity to prevent long-term osteoarthritis. His contributions continue to shape the understanding of meniscal biomechanics and improve outcomes for patients with knee injuries.
