Static or dynamic malalignment? The role of the patella maltracking for the emergence of the PFPS has long been a controversial issue. The role of the Q-angle (static measure) Recent studies, however, show that maltracking of the PFPS is discussed controversially [39, 41 patella probably plays a key role. Draper et al. [24] for Some authors report that an increased example have demonstrated by dynamic MRI that patients ciated with PFPS [39, 41]. For example, with a PFPS squat with increased lateralization and found that cross-country runners with in increased lateral tilt of the patella. Witvrouw et al.
