Measurement technique for the TTPCL/THD. Representative T2 MRI sequences acquired from a healthy 9-year-old boy. The mediolateral tibial tubercle-posterior cruciate ligament (TTPCL) distance was measured from (a) the medial border of the tibial insertion of the posterior cruciate ligament (PCL) and (b) the midpoint of the tibial tubercle (TT). The distance was measured parallel to the dorsal tibial condylar line (dTCL). The bony margins in the MRI scans were utilized except when measuring the tibial head diameter (THD).To determine the THD, the transversal plane with the maximum diameter of the tibial head was identified by the examiner (c).
