“…The interobserver and intraobserver variability for lateral radiographs were described with typical errors of 1.0°and 0.9°for the medial plateau, respectively [23]. We question whether such a small difference is relevant regarding the broad range of PTS variability reported in the literature [8,11,12,20,25,26,34,35,46,47], particularly regarding the fact that Todd et al found only females to have different values from the control group [47]. Although some studies relied on the use of the medial PTS, Stijak et al [46] focused on the lateral PTS and reported only a greater lateral PTS promotes injury.…”
