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...

Tibial tuberosity-trochlear groove (TT-TG) distance is a measure of lateralization of the tibial tuberosity in relation

measure of lateralization of the tibial tuberosity in relation to femoral trochlea. Many studies have confirmed that lateralization of the tuberosity is linked to patellar instability, thus TT-TG is an important parameter for evaluation of patellofemoral disorders. However, the degree of lateralization that may contribute to actual dislocation varies among studies. Alemparte et al. studied heal...
