In this study, we aim to describe, for the first time, patient-reported outcome measures after one year of knee arthroplasty surgery for patients operated with and without robotics and patients specific instrumentation, as recorded in the LROI since 2021. Patient demographics, diagnosis and type of operation will be described, which will allow for identification of selection bias in this first set of patients. This may generate valuable discriminative information between robotic systems, which are different by study and alignment philosophy.
