Fig. 1From: MRI analysis of tibial PCL attachment in a large population of adult patients: reference data for anatomic PCL reconstructionThe relevant measurements of the PCL tibial attachment. a MRI showing measurement of the APD of the tibial plateau; b MRI showing measurement of the angle (α) between the tibial plateau and PTS (posterior tibial ‘shelf’); c MRI showing measurement of the distance from the proximal (L1) and central (L2) positions of the tibial PCL attachment to the tibial plateau, the width (L3) of the attachment, and the length of the PTS; d MRI showing measurement of the vertical dimension (L4) of the PCL central attachment site from the tibial plateauBack to article page
