case_images: fig1-2050313X18823102
case_images: The cartilaginous area of the distal femur was fully exposed, but the open wound was not severely contaminated (Figure 1).

case_images: In spite of posterior knee dislocation, computed tomography angiography found no obvious arterial injury (Figure 2).
case_images: Postoperative X-P after external fixation (EF) was applied.

case_images: fig3-2050313X18823102
case_images: Surgical debridement, irrigation, and external fixation (EF) were performed (Figure 3).

case_images: In addition, the posterior translation of the tibia relative to the femur was >10 mm (Figure 4).
case_images: Postoperative CT following a reduction which achieved an appropriate

case_images: fig5-2050313X18823102
case_images: Therefore, surgical debridement and manual reduction under general anesthesia after the temporary release of the EF were performed, which achieved an appropriate reduction (Figure 5).

case_images: Thus, 2-mm K wires were inserted to connect the proximal and distal EF devices (Figure 6).

case_images: fig7-2050313X18823102
case_images: The soft tissue was closed in layers and valgus instability became negative in both the extension and slightly flex positions (Figure 7).
case_images: Clinical images at the time of the latest follow-up examination.

case_images: The patient had sufficiently recovered and returned to work in the construction field (Tegner activity scale score = 5) at 2 years after sustaining the injury (Figure 8).
