Sinding-Larsen-Johansson disease Its etilogy and natural history

Description: JBJS A 60-A #8 1113 (1978) Full Text
In a prospective study of children with pain in the knee, eight patients (ten knees) were seen with the clinical and roentgenographic findings of Sinding-Larsen-Johansson disease. The etiology appears to be a traction tendinitis with de novo calcification in the proximal attachment of the patellar tendon, which had been partially avulsed. The patients were followed through the course of the disease, which was found to be self-limited and benign like Osgood-Schlatter disease.
