Presentation
Neglected case of sports injury 3 months prior.
Patient Data
The MRI sequences demonstrate:
complete rupture of the proximal segment of the patellar tendon with a tendinous gap = 4 cm
retracted distal patellar tendon with intrinsic high signal
high-riding patella (patella alta)
the medial and lateral patellar retinaculum are thickened with abnormal intrinsic high signal but no evidence of disruption
No bony avulsion fracture
Moderate joint effusion
cruciate and collateral ligaments are intact as well as the posterolateral corner structures and menisci
small fibrous cortical defect of the lateral aspect of the distal femoral metaphysis (incidental finding)
Case Discussion
MRI features of complete patellar tendon rupture.
