Our patient presented with acute onset of pain and effusion with a history of feeling a \u201cpop\u201d in the knee after a fall while playing kickball. Although knee radiographs showed a cortical irregularity involving the superior patellar pole, it was assumed that the symptoms were a result of a JIA flare rather than an acute injury. Complete quadriceps disruption was later diagnosed by magnetic resonance imaging, and surgical repair was performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Complete rupture of the quadriceps tendon is an unusual, disabling injury in children that necessitates prompt diagnosis and early surgical repair.
