Close
There is extensive fluid superior to the patella, both within the joint space and in the soft tissues or perhaps the bursa. The quadriceps tendon is ill-defined and ruptured, with surrounding haematoma. There is wavy appearance of the patellar ligament. Prepatellar soft tissue swelling noted. Multiple suprapatellar calcified bodies, in keeping with osteochondromatosis.
No tibial, patellar or femoral fracture identified. Degenerative change is noted as well as meniscal calcification (chondrocalcinosis). The femoral attachment of the popliteus is heavily calcified.
Conclusion
Rupture of the quadriceps tendon. No fracture identified.
