India, Oct. 3 -- Robot-assisted hip and knee replacements produce no better results than conventional surgery, two large UK studies have found, raising questions over how quickly hospitals, including in India, have adopted the technology.

The studies, published in The BMJ, drew on National Joint Registry data for 666,283 total hip replacements, 10,203 of them robotic, and 697,145 total or partial knee replacements, 22,111 of them robotic, performed in UK public and private hospitals between 2018 and 2024.
