Joint replacement surgery has come a long way in the past couple of decades, giving patients who receive artificial knees or hips a very real improvement in the quality of their lives. And with a new procedure performed by Santa Rosa Orthopedic surgeons Michael McDermott, M.D., and Nathan Ehmer, D.O., such surgeries are advancing even further.

SRO NL Robotic surgery picDoctors McDermott and Ehmer are pioneering the use of robotic assisted MAKOplasty for some partial knee  replacement and hip replacement procedures. These new devices employ computer-aided robotics to help surgeons perform more accurate installations of artificial joints—reducing pain, shortening hospital stays and improving outcomes for SRO’s patients.

At the local Sutter Santa Rosa Regional Hospital, the robotic assisted arm is available for total hip replacement surgeries and for partial knee replacements—a common surgery for people suffering knee pain caused by osteoarthritis. For knees, Dr. McDermott said the RIO system offers a number of benefits, starting with a much smaller “mini-incision” that most patients equate with a faster recovery.

The result is a better balanced knee, faster recovery and improved performance after healing. “The robotic  assisted surgery isn’t right for every patient, but it can help improve outcomes in partial knee cases,”Dr.  McDermott said. For total hip replacements, the robotic device operates on the same concept. Successful
hip replacement surgery relies heavily on the accurate placement of the acetabular cup (where the rotating head of the femur attaches to the pelvis). Using the RIO to precisely locate the cup reduces the possibility of undue wear or even dislocation of the implant. The robotic arm also helps the surgeon make precision measurements to ensure the leg remains the correct length and the hip the correct width, giving the patient a smooth and natural feeling as he or she begins recovery.
