Tibial Tubercle–Midepicondyle Distance Can Be a Better Index to Predict the Outcome of Medial Patellofemoral Ligament Reconstruction Than Tibial Tubercle-Trochlear Groove Distance

The Influence of Tibial Tuberosity-trochlear Groove Distance on Development of Patellofemoral Pain Syndrome

Background: Tibial tuberosity-trochlear groove distance (TT-TGD) measurements play a decisive role in evaluatingpatellofemoral joint disorders. However, the prevalence of pathological TT-TGD among patients with patellofemoralpain remains unclear. The purpose of this study was to compare the size of TT-TGD among patients with patellofemoralpain syndrome (PFPS) and those with no history of patell...

The tibial tubercle-trochlear groove distance on axial CT and MRI: letter to the editor.

Systematic technique-dependent differences in CT versus MRI measurement of the tibial tubercle-trochlear groove distance.

BACKGROUND The tibial tubercle-trochlear groove (TTTG) distance is used to quantify the degree of lateralization of the patellar tendon insertion on the tibial tubercle relative to the deepest part of the trochlear groove. Disagreement exists as to whether the TTTG distance measured on computed tomography (CT) and magnetic resonance imaging (MRI) can be considered equivalent. PURPOSE To compa...
