Change in Tibial Tubercle-Trochlear Groove Distance During Adolescent Growth

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 Distance Shows no Change in Patients with or Without Knee Osteoarthritis.

Objective The primary aim of this study is to compare tibial tuberosity-trochlear groove (TTTG) distance in patients with or without knee osteoarthritis. Additionally, the variability of tibial tubercle according to trochlear groove was evaluated. Materials and Methods In this retrospective cohort study, TTTG distance was measured with two different methods on magnetic resonance (MR) images. ...

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...
