Surgical robots lead to lower complication rates after knee replacements, study finds


Patients who had robot-assisted total knee replacements had lower complication rates in the first three months after surgery, researchers at New York City-based Hospital for Special Surgery found.

Using a national database, the hospital assessed 1.3 million total knee replacements performed from 2010-18 and categorized them as conventional, technology-assisted or robot-assisted, according to a Nov. 12 news release. The data showed robot-assisted procedures had a 90-day complication rate of 1.57 percent while conventional knee replacements had a 2.55 percent complication rate.

The study also found that the use of robots in knee replacements nationwide jumped more than 2,200 percent between 2010 and 2018.

The findings were published in Arthroplasty Today.
