3. Double PCL sign. Bucket handle tear of the meniscus. Medial (3 points)

4. Anteromedial tibia and fibular styloid. MRI to evaluate for cruciate injury and posterolateral corner injury (1 each for fracture; 1 for MRI, 1 for why; 4 points)

5. Soft tissue mass anterior to the ACL reconstruction - Arthrofibrosis - cyclops lesion; Hates him. Limited extension. ACL reconstruction (3)

6. Comminuted patellar fracture. No. ORIF - Often with circlage wires and sometimes additional screws (3 points)

Bipartite and multipartite patellas - typically are more lateral than diffuse. There is a type involving the inferior patella - but medial is rare. This example is extensively fragmented - therefore it is more likely to be fractured.
