Fig. 5From: The relationship between quadriceps fat pad syndrome and patellofemoral morphology: a case–control studyMeasurement of tibial tubercle (TT) to trochlear grove (TG) was performed on two overlapping axial images. PCL, posterior condylar line; TG, perpendicular line from deepest point of trochlear groove to posterior condylar line; TG, perpendicular line from the tibial tubercle to posterior condylar line. TT–TG distance is the distance between red and blue linesBack to article page
