"The tibial tuberosity to posterior cruciate ligament (TT-PCL) distance is an alternative measure to the TT-TG distance for determining tibial tuberosity lateralisation, which has a role in patellofemoral instability, without the effect of femoral rotation 1."
"TT-PCL and TT-TG have similar reliability and sensitivity/specificity, however, TT-TG has greater diagnostic accuracy 5,6."
