Description
Michael S. Kim and co-authors track, in a 2026 study, how technology-assisted knee replacement spread across the United States from 2020 to 2024 and whether it outperformed manual surgery. Computer navigation and robotic help promise better implant alignment and soft tissue balance, but proof of clinical benefit has stayed mixed.
Drawing on the TriNetX network, the team identified 198,263 primary knee replacements and matched assisted and manual groups one to one on sex, body size, and health conditions. Assisted surgery's share climbed from 11.9 percent in 2020 to 27.0 percent in 2024. After matching, assisted cases carried lower risks of fracture around the implant, deep infection, revision surgery, and aseptic loosening across three years of follow-up, in every region studied. The authors back wider adoption while calling for long-term and cost studies.
