Irregularity and sclerosis of the primary ossification center of the patella.
Osteochondrosis of the primary ossification center of the patella (Köhler's disease of the patella) has been reported as a rare cause of anterior knee pain in children between 5 and 9 years of age. The etiology remains unclear. It affects the single knee usually but bilateral cases have been reported in the literature.
This entity should be distinguished from Sinding-Larsen-Johansson’s disease, which is an osteochondrosis of the secondary ossification center of the patella usually affecting the lower pole.
