Synovial Chondromatosis of the Knee in a 2-Year-Old Child: A Case Report and Review of the Literature

Case: We describe a rare case of synovial chondromatosis of the knee of a 2-year-old child. The diagnosis was based on the history, physical examination, and complementary examinations (radiography and magnetic resonance imaging). Anterior and posterior approaches were used for total synovectomy and resection of loose bodies.

Conclusion: Physicians should keep this condition in mind, even in young children, because early identification prevents future secondary degenerative changes in the knee joint. As far as we know, this is the youngest child with synovial chondromatosis of the knee reported in the English-language literature.
