“…Dennis et al [7] observed liftoff in 75% of CR-TKAs and cruciatesubstituting TKAs. Bertin et al [2] reported decreased liftoff laterally, with increased flexion (50% of subjects at 80°and 35% at 100°) and a reduction of lateral liftoff in the medial-pivot TKA: only one of five had liftoff. Whether the general lack of liftoff in our study was the result of the comparison of two different gap-balancing techniques remains unclear and warrants further investigation.…”

“…The ease of bending the knee 3 years postoperatively compared to 1 year may be the reason for the different positions. In vivo fluoroscopic studies avoid this problem by selecting the frames in 10°to 30°increments [2,4,5,13,16,17,23,24] at certain flexion angles. Second, our radiographs in flexion were nonweightbearing.…”
