Presentation
Received a blow against the knee 5 weeks ago. Persistent pain on extension and when rising from a chair.
From the case:
Quadriceps tendon partial tear
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/25425/annotated_viewer_json?iframe=true\u0026lang=us"}
The tendon at the patellar base is thickened and shows increased signal, especially on T1-weighted images. Wavy anterior contours of the tendon. T2-hyperintense peritendinous edema or residual hematoma.
Case Discussion
The findings suggest a non-acute partial rupture with scar tissue formation within the tendon.
