Se caracteriza por el crecimiento anormal de tejido cartilaginoso en la sinovial, lo que da lugar a la formación de cuerpos libres interarticulares, lo cual causa dolor. El diagnóstico se confirma por resonancia magnética (RM).  Caso clínico:  presentamos a masculino de 54 años con dolor, bloqueo articular, marcha dolorosa en rodilla izquierda de dos años de evolución sin antecedentes de trauma.  Conclusiones:  el tratamiento de resección de cuerpos libres en rodilla es por artroscopia, siendo la RM esencial para el diagnóstico y las decisiones terapéuticas.]]></p></abstract>

It is characterized by the abnormal growth of cartilaginous tissue in the synovium, which gives rise to the formation of inter-articular loose bodies causing pain; the diagnosis is confirmed by magnetic resonance imaging (MRI).  Clinical case:  we present a 54-year-old male with pain, joint blockage, gait painful left knee for two years with no history of trauma.  Conclusions:  the treatment of free body resection in the knee by arthroscopy, with MRI, is essential for diagnostic therapeutic decisions.]]></p></abstract>
