Figure 6
Influence of asymmetric quadriceps loading on patellar displacement for high muscle force. Patellar mediolateral shift (top) and tilt (bottom) during lateral (a) and medial (b) force application are illustrated, comparing the influence of three quadriceps force distributions (central, lateral, medial). Mean values and standard deviations are shown for 50 N mediolateral displacement force and a total of 150 N quadriceps force. Significant differences are identified by an asterisk.
