Early national comparison of robotic versus conventional knee replacements for arthritis using National Joint Registry data: target trial emulation study.

BMJ (Clinical research ed.)·September 30, 2026·PMID 42815981

Why it matters

Robotic knee replacement is increasingly adopted despite higher costs. This large national registry study provides early evidence that robotic assistance does not improve implant survival or reduce complications compared to conventional techniques, informing resource allocation and technology assessment in publicly funded healthcare systems.
