MAKO Surgical (Ft. Lauderdale, Florida), developer of human-interactive surgical robotic arm technology used to achieve accuracy in treating osteoarthritic disease, reported the first results from a ten-year, prospective, randomized controlled trial evaluating the accuracy of unicompartmental knee arthroplasty (UKA) implant positioning, with and without robotic arm surgical assistance. Early results from this pivotal study are compelling, showing that robotic arm assisted UKA enhanced the accuracy of implant placement and decreased the levels of pain.
