Sinding Larsen-Johansson syndrome is an osteochondrosis injury of the patella commonly seen in adolescents (between 10 to 14 years old). This case report covers an interesting case of Sinding Larsen-Johansson syndrome reported in a 33-year-old football athlete. He had been actively participating in many football tournaments for the last 18 years. He presented with anterior knee pain 1 month after experiencing a traumatic sports injury in one of his football matches. He was diagnosed with complete anterior cruciate ligament rupture, with medial and lateral meniscus injury. MRI confirmed the diagnosis with and additional finding of chronic Sinding Larsen-Johansson syndrome. He did not compete in further football matches, and underwent intensive physiotherapy focusing on eccentric muscle strengthening exercise. His anterior knee pain improved as well as his knee stability. This article will discuss Sinding Larsen-Johansson Syndrome in detail.
