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

BMJ (Clinical research ed.)·September 30, 2026·PMID 42815970

Why it matters

Robotic-assisted THR is increasingly adopted despite higher costs. This large national registry study provides early comparative effectiveness data, showing no overall survival or complication advantage but a specific reduction in malpositioning-related revisions. Orthopedic surgeons and health systems can use this to weigh the value of robotic technology against its capital and procedural expenses.
