Fig. 4From: Patellofemoral kinematics in dogs with cranial cruciate ligament insufficiency: an in-vivo fluoroscopic analysis during walkingAveraged plots of femorotibial flexion angle vs PF flexion angle during walking. For both femorotibial and PF flexion angle, greater values indicate greater extension. There was no difference in PF flexion at equivalent femorotibial flexion anglesBack to article page
