Dr. Stoker's research focuses on understanding disease pathogenesis and pathobiology; the identification of validation of biomarkers for early diagnosis, staging, treatment monitoring and prognostication; and developing and optimizing treatment strategies for osteoarthritis and other orthopaedic maladies. His research efforts have focused on the development, characterization and validation of numerous in vitro, ex vivo and in vivo models of osteoarthritis and other joint disease. He developed numerous models designed to expand the study of pathology associated with primary osteoarthritis, post-traumatic osteoarthritis, ACL tears and degeneration, meniscal deficiency, intervertebral disc disease, rotator cuff pathology and articular cartilage defects.

These models provide vital information regarding the response of joint tissue to various stimuli and the role of these tissues in the development and  rogression of orthopaedic disorders. Further, these models have consistently proven effective for the evaluation of the safety and efficacy of novel treatment strategies for these disorders. The basic science, translational and clinical research teams at the TLRO are making major progress in developing and validating improved treatment options for osteoarthritis using these models. He and the rest of the team have guided numerous therapies through the process of regulatory approval, clinical trials and post‐market studies. Their approach to placing science behind the surgery promotes safe and effective options for patients.
