Radiographs imaging (Figure 1) showed a type IIB right knee fracture and a type IIIB left knee fracture according to the Watson-Jones classification modified by Ogden et al..
Post-operative imaging at 4 months demonstrating anatomic reduction and fixation with cannulated full threaded 4.5 mm screws.

Within forty-eight hours of diagnosis, the patient underwent bilateral open reduction and internal fixation (ORIF; Figure 2).

X-rays (Figure 3) showed a type IIA right knee avulsion fracture and a type IIB left knee avulsion fracture according to the Ogden modified classification.

For both knees, the fracture sight was debrided allowing for anatomical reduction, and osteosynthesis was achieved using the same hardware: one 4.5 mm partially threaded cannulated screw (Figure 4) placed distally to the physics with washer and precise reconstruction of the surrounding soft tissues.

Intraoperatively complete detachment of the patellar tendon was documented for both knees (Figure 5) that has been treated by direct suturing.
