ABSTRACT

The osteochondroses are a heterogeneous group of injuries to the epiphyses and apophyses of children or adolescents. The breakdown of endochondral ossification and bone fragmentation are seen radiologically. The aetiology of osteochondroses remains uncertain. Catch-up growth or strenuous sports activities have been thought to be the cause of this benign disease. In condition of patellar osteochondrosis, rarely the primary ossification centre is affected known as Köhler’s disease. More frequently, the secondary ossification centre, usually at the distal pole known as Sinding- Larsen-Johansson. Superior pole osteochondrosis of patella has been reported in the literature on only a handful of occasions. We presented the clinic and radiologic findings of an eleven year-old boy with superior pole osteochondrosis patella.
