Osteochondrosis of Superior Pole of Patella

xlomafota13 shared this article with you from Inoreader Osteochondrosis of Superior Pole of Patella Via Neuroradiology Cases Clinically young male patient with athletic background complaining of typical unilateral anterior knee pain. Marked tenderness at the superior pole of patella. This MRI study of knee joint shows abnormal irregularity, fragmentation with sclerosis involving superior pole of patella with thickening of quadriceps tendon. Associated knee joint effusion. Imaging findings consistent with osteochondrosis of patella at superior pole. Osteochondrosis of the superior pole of the patella Osteochondroses are a heterogeneous group of injuries to the epiphyses and apophyses of children or adolescents, are actually osteonecrosis repetitive microtrauma and avulsion injuries. Imagingwise characterized by bone fragmentation and sclerosis. There are two well-known such syndromes associated with knee joint one is Osgood-Schlatter disease, an avulsion of the tibial tuberosity and another is Sinding-Larsen-Johansson disease, a chronic avulsion injury of the lower pole of the patella at the insertion of patellar t endon. The less well described osteochondrosis at the superior pole of patella appears secondary to similar mechanism associated with quadriceps tendon insertion, a rare cause of anterior knee pain in children between 5 and 9 years of age, usually affects the single knee but bilateral cases have also been reported.
