Sinding-Larsen Johansson disease
Sinding-Larsen Johansson disease(sĭn″dĭng-lăr″sĕn jō-hăn′sŏn)
Anterior knee pain caused by persistent traction on an immature inferior patellar pole. There is point tenderness at the bone-tendon junction, and Osgood-Schlatter disease may be present. The adult equivalent of this disease is patellar tendinitis. This condition occurs commonly in boys 10 to 12 years of age who are actively involved in running and jumping sports. It resolves eventually but can be treated with activity modification, a patella-stabilizing knee brace, ice, and nonsteroidal anti-inflammatory drugs.
