Value from the tibial-tuberosity to trochlear groove distance in the patellofemoral instability. MEDISAN [online]. 2021, vol.25, n.1, pp.194-203.  Epub 08-Feb-2021. ISSN 1029-3019.

The patellofemoral instability is an entity that mainly affects adolescents and young adults. In its diagnosis clinical and imaging elements are considered, especially to measure the tibial-tuberosity to trochlear groove distance that allows the selection of the surgical technique in each patient, in specific the transfer of the tibial-tuberosity. In this work some aspects of interest on the topic are shortly exposed: the imaging methods used in these patients (simple x-rays, computerized axial tomography, magnetic resonance imaging) and the reference values considered as normal; it is also described step by step how to measure the tibial-tuberosity to trochlear groove distance.

Palabras clave : patellofemoral articulation; patellofemoral instability; computerized axial tomography; magnetic resonance imaging.
