Need a New Knee or Hip? A Robot May Help Install It

As more people strive to stay active on aging frames, robots and other technologies are likely to play a wider role in helping surgeons replace joints.

In the first joint replacement surgery in 1890, the German surgeon Themistocles Gluck implanted “carved and machined pieces of ivory” into joints diseased by tuberculosis — starting with a knee replacement for a 17-year-old girl, according to the medical historian and author Dr. David Schneider.

The implants used today, as well as those doing the implanting, are radically different from those in the days of Themistocles Gluck.

In thousands of such procedures, robots are now assisting surgeons to ensure an optimum fit of the new joint. Although many doctors still perform the procedures successfully without their assistance, the robots’ ability to help achieve more precise implant positioning — often determined through 3-D computerized modeling of the patient’s joint before the actual procedure — makes their role likely to grow over the next decade as the implants become more individualized, and such technologies as augmented reality are integrated into the operating room.

And the replacements themselves have changed. Over the past century, they have evolved to include metal, plastic and ceramics, and are now made of titanium, cobalt chrome and specially reinforced plastics. (Gone are the metal-on-metal replacements that caused problems in hip replacements in the past).

But something else important has also changed: the psychology of the patients, specifically, baby boomers. Now in their late 50s, 60s and 70s, they represent about half of the patients for the most common, knee and hip replacements.

“This is the first generation that is trying to stay active on an aging frame,” said Dr. Nicholas DiNubile, an orthopedic surgeon in Havertown, Pa. “My parents weren’t active at all. If they went out and did something and were sore afterwards, they’d never do it again. But baby boomers stay active, in droves.”
