Simultaneous avulsion of patellar apexes bilaterally in a hemodialysis patient.
A case of simultaneous bilateral avulsion of the patellar apexes is reported. Plain radiography showed bilateral patella alta, but MR imaging was diagnostic. Weakness of the tendo-osseous junction due to secondary hyperparathyroidism and additional chronic inflammatory changes due to repeated microtrauma were considered to be the cause of the rupture.
