title: [Pellegrini-Stieda syndrome as a cause of knee pain].
abstract: Calcification in the soft tissue next to the medial femoral condyle after a history of trauma around the knee is a recognized radiographic finding-PS (Pellegrini-Stieda) sign. When this is associated with pain and a restricted range of motion it is known as the PS syndrome. We describe two cases of PS syndrome, treated conservatively with rest and physiotherapy, as well as the radiographic and ultrasound findings, and the many theories proposed in attempts to explain the pathogenesis of PS disease.
