Measurement conventions for both hip joints follow previous XROMM studies, whereas knee and ankle measurements follow the prism‐based hinge joint convention presented in this study. All values reflect right‐sided conventions for positive measurements. See Kambic et al., (2014) for hip joint conventions; for knee joints, right‐sided positive X represents joint distraction, positive Y represents relative anterior motion of the distal element, and positive Z represents relative lateral motion of the distal element; for the ankle joint, right‐sided positive X represents joint distraction, positive Y represents relative posterior motion of the distal element, and positive Z represents relative medial motion of the distal element (see Method S1)
