Our physicians perform more than 800 joint replacements each year, putting DOC in the top one percent in volume of joint replacements performed in the United States by a single orthopedic group. In fact, thanks to recent technological developments, the replacement of knee, hip, shoulder, finger, wrist and ankle joints has become routine procedure. Our physicians also perform complicated revision surgery, which involves removing failed implants and reconstruction of the joint. DOC is actively involved in research and development of improved implant materials and techniques.
