Superior Patellar Dislocation Misdiagnosed as Patellar Tendon Rupture: The Value of Ultrasonography

Table 1

Additional imaging modalities.

Modality	Benefit
Ultrasound	(i) Evaluating the integrity of the patellar tendon [4, 10, 18].; (ii) Evaluating the medial structure injury such as vastus medialis tear [4].; (iii) Follow-up immediately after closed reduction [4, 18].
3D-computed tomography	(i) Evaluating the osteophytes at the inferior aspect of the patella and at the superior aspect of femoral condyle [1].
Magnetic resonance imaging	(i) Evaluating the integrity of the patellar tendon [4, 9, 13].; (ii) Evaluating the osteophytes at the inferior aspect of the patella and at the superior aspect of femoral condyle [4, 9, 13].; (iii) Evaluating any associated injury such as vastus medialis tear [4].; (iv) Evaluating the cartilage and other intra-articular pathologies.
