Presentation
One week post fall while walking.
Patient Data
Extensive subcutaneous oedema around the knee. Small knee joint effusion.
Complete distal quadriceps tendon rupture with the gap on a background of severe tendinopathy. Mild muscle belly oedema within the distal quadriceps group. Prepatellar subcutaneous fluid in continuation with the small joint effusion via the tendon gap.
Patellar tendon is intact but redundant. Patella is low-lying.
Case Discussion
Typical MRI findings of quadriceps tendon rupture. The history of fall is typical with knee extension occurring as an attempt to break the fall, resulting in overload and rupture of the tendon.
