Considering the influence of quadriceps muscle activation on the patellar shift, patients with PFI show a preoperative increase in extension ( p = 0.001) and a statistical trend at 15° flexion ( p = 0.056).
Considering the influence of quadriceps muscle activation on the patellar shift, patients with PFI show a preoperative increase in extension ( p = 0.001) and a statistical trend at 15° flexion ( p = 0.056).
In the present study, the influence of muscular activation on the different KPs in the patients with PFI was evident in both patellar shift and tilt (each highly significant in extension and 30° flexion, with a statistical trend in 15° flexion).
