Intra-articular Large Ossicle Associated to Osgood-Schlatter Disease

摘要

Osgood–Schlatter disease (OSD) is known as a self-limiting condition but surgical excision of the ossicles may be required in adults resistant to conservative treatments. The ossicle associated to OSD is generally small and located outside the joint near the tibial tubercle; however, large or intra-articular ossicle has been reported rarely. Here, we report an unusual case of OSD with a separated, large-sized ossicle that protruded into the knee joint and treated by arthroscopy-assisted excision of the ossicle.
