Instrucción Ortopédica de Posgrado - Imágenes. Resolución del caso. [Post-Graduate Orthopedic Instruction: Imaging. Answer to Case Study]

Patellar tendon-lateral femoral condyle friction syndrome is discussed, a condition that has received little attention in orthopedic literature. In many cases, it is an incidental finding on MRI when there is no clinical suspicion or even confirmation of Hoffa fat pad impingement (FPI) syndrome. Identification of pathognomonic findings on imaging studies is key, both for selecting the adequate treatment option and to distinguish this condition from other causes of anterior knee pain. Although there is currently no definitive etiology for the syndrome, its identification is important for both diagnosis and treatment.Se describe el sindrome de friccion del tendon patelar-condilo femoral, que es una entidad que ha recibido poca atención en la literatura ortopédica, y en muchas ocasiones constituye un hallazgo en las imágenes de RM sin sospecha clínica ni conocimiento de la existencia del cuadro de impingement del sector superolateral del paquete adiposo infrarotuliano de Hoffa (PAI). Es importante que se identifiquen los hallazgos característicos de las imágenes, tanto para la correcta elección del tratamiento como para distinguir esta entidad de otras causas de dolor anterior de rodilla. Si bien no existen en la actualidad respuestas definitivas con respecto a la etiología del síndrome, su identificación tiene implicaciones importantes tanto para el diagnóstico como para el tratamiento.
