“…Franceschi et al reported the first case of simultaneous location of osteochondroses of the two ossification centers of both patellae in 9-year-old boy [ 2 ]. Sakai et al found osteonecrosis of the patella in nine patients (ten knees) while evaluating non-traumatic osteonecrosis of the femoral head in 60 patients [ 4 ]. Pinar et al have been reported three similar cases and concluded that the process either physiological or pathological has a benign course and favorable prognosis [ 17 ].…”

“…Patellar osteonecrosis has been described as an unusual cause of patellofemoral pain syndrome. 2,[9][10][11][12]14,18,[21][22][23]27 It usually is related to corticosteroids, 14,18,21,27 patellar fracture, 23 total knee replacement, 2,9 and, in rare cases, is idiopathic. [10][11][12]22 Conventional radiographs, bone scan, and MRI have been reported as the methods of choice to diagnose this condition.…”

“…On MRI, these lesions appear as regions of diffuse hypointensity or areas of normal fat intensity surrounded by a hypointensity band on T1weighted images with spin echo sequences. 21 The superolateral pole is the most common location of these osteonecrotic changes. 24 Magnetic resonance imaging also is used to investigate defects in articular cartilage.…”
