About

Stephen T. Mathew is a leading orthopaedic researcher whose work centers on the biomechanics of the knee, particularly the long-term consequences of anterior cruciate ligament (ACL) injury and reconstruction. His major contributions lie in elucidating the relationship between altered joint kinematics and abnormal tibiofemoral contact stress, a key factor in the development of post-traumatic osteoarthritis. His seminal 2013 study, which has garnered 94 citations, provided critical evidence that even anatomically precise "center-center" ACL reconstruction fails to restore normal contact stress patterns, directly linking surgical outcomes to degenerative joint disease. This work has reshaped clinical understanding of ACL rehabilitation and surgical technique. Beyond this landmark paper, Mathew’s research portfolio consistently demonstrates how subtle kinematic changes—often undetectable in standard clinical exams—can drive significant cartilage overload. His findings have been instrumental in advancing patient-specific rehabilitation protocols and refining surgical alignment strategies. For students and researchers, Mathew’s work serves as a vital bridge between basic biomechanical science and practical orthopaedic care, underscoring the importance of long-term functional outcomes over short-term surgical success.
