I believe in a patient-centered holistic approach to musculoskeletal medicine. I discuss the current evidence regarding the patient's condition, treatment options, expected outcomes, their surrounding ongoing life events, and to help them make a patient-centric overall decision regarding their musculoskeletal health. I care and treat every patient as if they are my own family members.
Dr. Lum is a fellowship-trained, board certified orthopaedic surgeon who cares for patients with various musculoskeletal conditions. He is trained to manage sports medicine injuries, fractures, and conditions of the upper extremity. He has specialized expertise in hip and knee reconstruction and revision arthroplasty, and is trained in computer navigated and robotic hip and knee replacement.
Dr. Lum's research focuses on several areas of interest. He is committed to continuing the development of human kinematics, specifically in both the knee and the spinopelvic regions and he is forward thinking in how to treat hip & knee periprosthetic joint infections by reducing the number of patient operations using a single stage, single operation technique. Most importantly, Dr. Lum is committed to health equity, diversity and inclusivity and is working to improve the lives and access of marginalized patients with social determinants of health.
