Fig. 2From: The effect of knee joint rotation in the sagittal and axial plane on the measurement accuracy of coronal alignment of the lower limbExample of the FLWAP image and the EOS image in the same patient. The images were taken in the same position with the knee not to flex intentionally and the patella facing forward. The mTFA on the FLWAP image was represented as a yellow line in (a), and the mTFA on the EOS image was semiautomatically displayed (b, c).
