Another manifestation of juvenile traction osteochondritis? Batten J, Menelaus MB. J Bone Joint Surg Br. 1985 Mar;67(2):249-51
Six boys with fragmentation of the proximal pole of the patella are reported; the condition was bilateral in one. Four of the six presented with symptoms of Osgood-Schlatter's disease or Larsen-Johansson disease of the...

Sinding-Larsen-Johansson syndrome is inflammation of the kneecap (patella) at its lowest point. This is the site of origin of the patellar tendon. There is traction on the kneecap at this point due to action of the large, powerful thigh muscle (quadriceps), as well as with deep bending of the knee....

Sinding Larsen-Johannson disease may cause or feature knee pain due to osteochondritis contusion and subsequent tendonitis in the proximal attachment of the patellar tendon

contusion and subsequent tendonitis in the proximal attachment of the patellar tendon can be followed by calcification, ossification, or frank inferior pole avulsion fractures that produce one or more distinct ossicles. per Stedman's dictionary: "apophysitis of the distal pole of the patella" symptoms: tenderness and soft tissue swelling over the...

Notes and Illustrations
Children and adolescents 10-14 years
Knee pain aggravated by activity
Tenderness and soft tissue swelling over the inferior pole of the patella.
Probably traumatic (traction injury) origin
Closely related to Osgood-Schlatters
Tendinitis, followed by calcification or ossification.
X-ray - osseous fragmentation at lower pole patella
NOT an apophysitis...
