The image intensifier, together with customized manual instrumentation, was used for separately measuring the frontal alignment of the femoral and tibial resection surfaces. The surgeon adjusted the resection surfaces when a mechanical axis deviation error angle of \u22650.5\u00b0 was observed on the fluoroscopic image. Coronal alignment was measured on standing long\u2010leg digital radiographs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Patients operated with fluoroscopy assistance had (1) a lower risk of malalignment at the threshold of &gt;3\u00b0 (risk ratio, 0.7; 95 % CI, 0.13\u20131.2), (2) a mean fluoroscopic time of 3 s, and (3) a longer operative time (69 vs. 60\u00a0min, <jats:italic>p<\/jats:italic> &lt; 0.001).
