No significant differences were observed between the two groups with respect to preoperative demographic characteristics, range of motion (ROM) and radiographic knee alignment. At a mean follow\u2010up of 29\u00a0months, the Journey BCS group had higher mean Knee Injury and Osteoarthritis Outcome Score (KOOS) in all subscales and a greater ROM than the Scorpio NRG group. This difference was statistically significant for the KOOS subscales of pain (<jats:italic>p<\/jats:italic> = 0.007) and knee\u2010related quality of life (<jats:italic>p<\/jats:italic> = 0.045), as well as for postoperative ROM (<jats:italic>p<\/jats:italic> = 0.018). Considering the overall complications, 1 patient of Scorpio NRG group (0.5 %) and 5\u00a0in Journey BCS (2.7 %) had stiffness. Anterior knee pain was reported in 4 cases of Scorpio NRG group (2.1 %).
