case_images: The radiograph (X-ray) and computed tomography scan (CT scan) showed a displaced avulsion fracture of the PCL tibial attachment, a displaced avulsion fracture of the LCL femoral attachment and a comminuted fracture of the inferior pole of the patella (Figures 1 and 2).
case_images: Coronal (a, d), axial (b), and sagittal (c) CT scan on admission to the Emergency Department.

case_images: fig5
case_images: A 2.5 cm longitudinal incision was made just medial to the tibial tubercule, and two parallel 2.5 mm K-wires were inserted through the tibial PCL guide to the medial and lateral borders of the tibial footprint, respectively (Figure 5).
case_images: MRI (T2-weighted) axial view - schematic representation of each suture (yellow and blue lines) crossing the posterior part of the base of the PCL and exiting the contralateral tunnel (a). Arthroscopic posteromedial view - interlaced suture configuration for PCL avulsion fracture (b).

case_images: fig6
case_images: Each suture crossed the posterior part of the ligament, passed the loop, and pulled to the outside through the contralateral tunnel, creating an interlaced suture configuration (Figure 6).
