Sinding-Larsen-Johansson syndrome with minimally displaced patellar sleeve avulsion fracture: a case report with multimodality approach and literature review

Eduardo Negrão et al. Skeletal Radiol. 2023 Jul.

Abstract

Sinding-Larsen-Johansson syndrome is an osteochondrosis affecting the inferior pole of the patella. Most cases can be easily diagnosed with adequate clinical history, physical examination, and proper imaging, including conventional radiography, ultrasound, and magnetic resonance imaging. Differentiating this condition from patellar sleeve avulsion fractures is important, since treatment is frequently surgical in the latter. Overlap between these two conditions can also occur. We present a case of an 11-year-old boy, with Sinding-Larsen-Johansson syndrome on both knees and a minimally displaced acute patellar avulsion sleeve fracture of the left knee, which was treated conservatively.

Keywords: Anterior knee pain; Osteochondrosis; Patellar sleeve avulsion fracture; Pediatric knee pathology; Sinding–Larsen–Johansson syndrome.
