Reveal Clinical Notes

Diagnosis was Osgood Schlatter disease clinically.

Reveal Findings

Fragmentation of the inferior patellar pole, edema within and surrounding the proximal patellar tendon.

Reveal Discussion

Sinding Larsen Johansson disease is in the spectrum of overuse injuries of the patellar tendon and is considered an osteochondrosis. The disease is most common between the ages of 10-14 and is most likely due to repetetive traction on the inferior patella by the patellar tendon.

Plain radigraphic findings include fragmentation of the inferior patellar pole and edema and indistinctness of the proximal patellar tendon and surrounding tissues. MRI findings are similar. Patellar fragmentation is a late finding.

Differential considerations include jumpers knee (skeletally mature patients with edema in proximal patellar tendon, but normal bone), Osgood Schlatter or patellar sleeve fracture(acute injury rather than chronic).
