Description

Osteochondrosis involving apex of patella. Reckoned among the aseptic necroses of bone. Generally affects adolescents between 10 and 14 years of age and prevalent in boys. Pain and tenderness over inferior pole of patella precipitated by overstraining or trauma. Limping. Accompanied by radiographic evidence of osseous fragmentation. The lesion is felt to be due to a traction phenomenon in which contusion or tendinitis in the proximal attachment of the patellar tendon can be followed by calcification and ossification, or in which patellar fracture or avulsion produces one or more distinct ossification sites. The natural duration of the disease is approximately 3 to 12 months.
