A 46-year-old female presented to the emergency department with a rare superior dislocation of the patella. Magnetic resonance imaging revealed inferior osteophytes on the patella engaging osteophytes on the superior portion of the trochlear groove resulting in a locked superior patellar dislocation. A closed reduction was performed, resulting in immediate pain relief and nearly full active range of motion

Abstract: A 46-year-old female presented to the emergency department (ED) with complaints of significant anterior knee discomfort, swelling and inability to ambulate or actively flex her knee. She reported falling at home and striking her right knee directly on a piano stool. She denied any history of injury to the right knee and reported only occasional mild anterior knee pain with kneeling or squatting prior to this accident. Initial examination in the ED showed a prominent and superiorly displaced patella.
