Sinding-Larsen-Johansson syndrome: A case report

Sinding Larsen-Johansson syndrome is an osteochondrosis injury of the patella commonly seen in adolescents (between 10 to 14 years old). We reported a case of a 12-year-old boy. He had been actively participating in many football tournaments for the last 18 years. He presented with tenderness at the inferior pole of the patella associated with focal swelling and restriction of knee joint range of movement. MRI confirmed the diagnosis of the Sinding Larsen-Johansson syndrome.
