Abstract
Fabella, a small ossicle at the posterolateral aspect of the knee, is potentially a source of knee pain. Although fabella syndrome is a rare cause of knee symptoms in young adults, osteocartilaginous degeneration prominent in the fabellofemoral joint on magnetic resonance imaging may be commonly seen in elderly patients.
