As RA\u2010TKA continues to gain popularity, it is important to compare outcomes with the more established technique to justify its use. This study compares PROMs for imageless RA\u2010TKA versus CN\u2010TKA, and between RA\u2010TKA performed with either ROSA or CORI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This was a retrospective study of prospectively collected data of patients who underwent primary TKA for osteoarthritis (OA). The study included consecutive surgeries between December 2021 and April 2023, utilising imageless RA\u2010TKA (ROSA or CORI) or CN\u2010TKA. PROMs were obtained preoperatively, at 3 months, and at 12 months, including the Oxford knee score (OKS), Forgotten Joint Score (FJS), Veterans Rand 12\u2010item mental and physical health survey (VR\u201012), pain (visual analogue scale [VAS]) and patient satisfaction scores.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 399 patients were recruited: 212 underwent RA\u2010TKA (CORI:\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009104; ROSA:\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009108), and 187 underwent CN\u2010TKA. There were no significant differences between groups at baseline. At 12 months, patient satisfaction with medical care favoured CN\u2010TKA (adjusted mean difference: \u20133.94; 95% CI: \u20137.44, \u20130.45). Between ROSA and CORI systems, patients' subjective knee normality score favoured CORI (adjusted mean difference: \u20138.44; 95% CI: \u201316.0, \u20130.90). No other meaningful differences were observed in either comparison.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study showed no difference in PROMS (OKS and FJS) between CN\u2010TKA and RA\u2010TKA; however, a modest benefit was seen in patient satisfaction with medical care favouring CN\u2010TKA. Similarly, only a modest difference was identified between ROSA and CORI, with knee joint normality favouring the CORI system. These findings demonstrate no clear short\u2010term benefit for well\u2010established navigation surgeons to change to robotic techniques, although further investigations would be
