The goal of this study was to utilize the NAVIO robotic-assisted (RA)-TKA technique to assess whether a knee that is well-balanced at 0 and 90 is also well balanced in mid-flexion. Using a 3mm threshold to define soft-tissue balance, results demonstrated that 11.5% of knees studied could be expected to be unstable in the mid-flexion arc (15-75) despite being well-balanced at the static poses at 0 and 90.
