At DOS we are focused on a higher level of sub-specialty Orthopaedic care. Our team of joint replacement surgeons developed pre and post op protocols to best ensure your surgery proceeds as planned. Dr. Dellose and Dr. Rubano perform the most primary and revision joint replacements in Delaware. We also provide joint replacement care to more Delawareans than any other orthopaedic group. DOS has the only two fellowship-trained joint replacement surgeons in New Castle County. We are the only two orthopedic surgeons in Delaware who are active members of the Amercian Association of Hip and Knee Surgeons and whose membership includes the elite surgeons in the field of joint replacement surgery.
