“The results were<br />

everything I had<br />

hoped <strong>for</strong>.”<br />

Robotic-Assisted Hip Surgery Restores the Spring in Her Step<br />

While there’s no discounting the many benefits of<br />

aerobic exercise, teaching aerobics classes <strong>for</strong> countless<br />

years eventually took its toll on Sharon’s left hip. “In<br />

the type of aerobic dancing I taught, every step began<br />

on the left side,” said Sharon. “Over time, the constant<br />

pressure on my left hip gradually wore down the joint<br />

cartilage until it was bone on bone. It got to the point<br />

that I couldn’t even walk without limping.”<br />

Sharon talked to people who had undergone hip<br />

replacement surgery and heard Dr. Bargar’s name<br />

mentioned so often that she decided he was the one she<br />

wanted to per<strong>for</strong>m her surgery. In February <strong>2008</strong>, she<br />

went to see William Bargar, M.D., <strong>for</strong> the first time and<br />

heard that the latest generation of the robotic surgical<br />

assistant Dr. Bargar had helped develop many years<br />

be<strong>for</strong>e would soon be tested in a clinical trial.<br />

Dr. Bargar explained that the system would allow him<br />

to use diagnostic images to assess Sharon’s hip anatomy<br />

and condition, select the best hip implant type and size,<br />

and determine its optimal placement. During surgery,<br />

the system would assist him again, this time in carrying<br />

out the plan and preparing the femur <strong>for</strong> implant<br />

placement to ensure the implant was set at the correct<br />

angle. Dr. Bargar’s experience in hip replacement,<br />

combined with his confidence in the improved accuracy<br />

the system would provide over manual surgery<br />

techniques, convinced Sharon to enroll in the clinical<br />

trial.<br />

“The results were everything I had hoped <strong>for</strong>,” said<br />

Sharon. “I didn’t even have to take pain medication<br />

after the surgery. Eight or nine days after the surgery, I<br />

was able to walk up and down the stairs at home. My<br />

physical therapist said I could go down once in the<br />

morning and up again at night, and I was very careful<br />

to follow all instructions exactly, which I’m sure helped<br />

contribute to my results. My greatest fear was that the<br />

hip would pop out, but it settled right in and healed<br />

beautifully.”<br />

Today Sharon does not enjoy pain-free hips, however.<br />

“I do a lot of walking, and I can honestly say that I’ve<br />

never felt any pain in my left hip,” Sharon said, “but I<br />

have arthritis in my right hip now — and that’s the only<br />

hip that ever hurts.”
