    Clinical Assistant Professor, Orthopaedic Surgery

    BioDr. Viess is a board-certified orthopaedic surgeon with subspecialty board certification in sports medicine.He delivers care at Stanford Health Care – ValleyCare in Pleasanton. Dr. Viess focuses on arthroscopic surgery and sports medicine, with a special interest in arthroscopic reconstruction of the shoulder and knee.

    Topics include the biomechanics of pitching, and shoulder and elbow injuries in the throwing athlete. Dr. Viess is a fellow of the American Academy of Orthopaedic Surgery and a member of the California Orthopaedic Association.

    He strives to offer his patients the most advanced, least invasive surgical procedures, including ACL reconstruction, meniscal surgery, and arthroscopic rotator cuff and labral repairs. Dr. Viess has extensive experience in the management and treatment of sports- related orthopedic injuries. He served as Assistant Team Physician
    for Major League Baseball’s Oakland As, providing game coverage and conducting pre- and post-season physical exams. For six years, Dr. Viess directed the Stanford Health Care – ValleyCare Sports Medicine Program. He also served as the team physician for Granada High School in Livermore, California.

    In addition to his clinical practice, Dr. Viess has conducted research, including a 10-year review of clinical satisfaction, revision rates, and radiographic evidence of stem fixation associated with the Ultimate-C femoral stem. He also led a study evaluating capsular sling repair during total hip arthroplasty.

    Dr. Viess has made numerous presentations to peers and to the community. Peer-targeted topics include graft selection in ACL reconstruction, concussion
    management, and on-field management of spine injuries. At the Lake Tahoe Sports Medicine Conference, he has presented lectures on PCL ruptures, multi-ligament knee injuries, and AC joint sprains. He also has delivered lectures for family practitioners on the evaluation and physical examination
    of orthopaedic patients. For the community, Dr. Viess has made presentations at health fairs and schools. Topics include the biomechanics of pitching, and shoulder and elbow injuries in the throwing athlete.

    Current Research and Scholarly InterestsOur lab’s mission is to develop therapies for regenerating human tissues lost due to diseases or aging, and to build tissue engineered 3D models for understanding disease progression and informing drug discovery. We invent biomaterials and engineering tools to elucidate and modulate biology, and also use biology to inform materials and engineering design. Our work is highly interdisciplinary, and is driven by unmet clinical needs or key gaps in biology.
