• Background This study investigated the accuracy in achieving proper lower limb alignment and component positions after total knee replacement (TKR) with image‐free and image‐based robotic‐assisted TKR. Methods A total of 129 patients (166 knees) suffering from end‐stage knee arthritis who underwent TKA operated by robotic‐assisted surgery between the years 2018 and mid‐2021 were recruited. Radiological outcomes were compared between image‐free and image‐based robotic‐assisted surgical systems. Results There were significant differences between the two robotic systems when comparing the mean planned component alignment and the mean measured alignment on radiographs, in which the image‐free robotic‐assisted system was more varus, whereas the image‐based robotic‐assisted system was more valgus for both the mean femoral and tibial component coronal alignment (p < 0.001). For tibial component sagittal alignment, the image‐based group had a larger deviation from the planned posterior slope (p < 0.001). Conclusion Image‐free and image‐based robotic assisted TKR had differing accuracy in femoral and tibial alignment.
