RT Journal Article T1 Ultrasound-guided percutaneous lavage of calcific bursitis of the medial collateral ligament of the knee: a case report and review of the literature A1 Del Castillo, Federico A1 Ramos Álvarez, Juan José A1 González Pérez, José A1 Jiménez Herranz, Elena A1 Rodriguez Fabián, Guillermo AB OBJECTIVES:Calcification of the medial collateral ligament (MCL) of the knee is rare. The literature reports no positive outcomes when conservative treatment has been followed. This paper reports a case of such calcification and its treatment using ultrasound-guided percutaneous lavage (UGPL).METHODS:A 66-year-old patient presented with medial knee pain. X-ray, ultrasound, and magnetic resonance (MR) examinations revealed calcific bursitis of the MCL, which was treated by UGPL.RESULTS:One month after treatment the patient was asymptomatic. X-ray, ultrasound, and MR examinations confirmed the almost complete disappearance of the calcification; only very tiny fragments remained.CONCLUSIONS:Calcific bursitis of the MCL of the knee is very uncommon, but should be taken into account in differential diagnoses for medial knee pain. UGPL is proposed as a treatment for this condition.
