Findings:

Diagnosis:
Plicae Suprapatelar.
Discussion:
La plica es una estructura normal, que representa remanentes de tejido sinovial, de la etapa embrionaria.
Tipos: Suprapatelar, Infrapatelar, Lateral y Medial.
Puede encontrarse en pacientes asintomáticos, pero aparece dolor, crepitación o derrame articular, luego de trauma, inflamación o frecuente actividad deportiva.
Se aprecia como imagen hipointensa y lineal, dentro de tejido inflamatorio o derrame. Su presencia no indica patología. Clinicamente significativa, cuando aparece engrosada y con sinovitis asociada.

The plica is a normal structure, that it represents synovial weave surpluses, of the embryonic stage.
Types: Suprapatelar, Infrapatelar, Lateral and Medial.
It can be in asymptomatic patients, but it appears pain, crackle or it spills to articulate, after trauma, inflammation or frequents sport activity.
It is appraised like hypointense and linear image, within inflammatory weave or spills. Its presence does not indicate pathology. Clinically significant, when she appears thickened and with associate synovitis.
