Cases include approximately 185 total hip replacements, 219 total knee replacements, 37 hip revisions and 23 total knee revisions. The anterior approach to the hips is routinely performed by all surgeons for most total hip replacements. Computer navigation is used routinely by two of our surgeons. In addition to the high volume of adult reconstructive cases, we have one surgeon specializing in hip arthroscopy, impingement surgery, and pelvic osteotomies.
