The fabella is a sesamoid bone that can very occasionally act as a source of atypical knee pain, often mistaken for a more common cause of clinical symptoms, such as an intra-articular loose body or an osteophyte. We report a case of symptomatic dislocation of an osteorthritic, enlarged fabella, 4 years alter total excision of the patella for a comminuted fracture, that was primarily overlooked and led to repeated diagnostic arthroscopy of the knee. A thorough history and physical examination of the joint as well as appropriate roentgenographic studies could have spared this patient an unnecessary arthroscopy and indicated the correct therapy.

Abstract
The fabella is a sesamoid bone that can very occasionally act as a source of atypical knee pain, often mistaken for a more common cause of clinical symptoms, such as an intra-articular loose body or an osteophyte. We report a case of symptomatic dislocation of an osteorthritic, enlarged fabella, 4 years alter total excision of the patella for a comminuted fracture, that was primarily overlooked and led to repeated diagnostic arthroscopy of the knee. A thorough history and physical examination of the joint as well as appropriate roentgenographic studies could have spared this patient an unnecessary arthroscopy and indicated the correct therapy.
