(a) The result of the motor nerve conduction velocity showed the left peroneal nerve palsy. (b) The nerve conduction velocity of the right peroneal nerve. (c) The nerve conduction velocity of the left peroneal nerve. The left peroneal nerve conduction velocity could not be derived 5 days after injury.

The nerve conduction velocity could not be derived 5 days after injury (Figure 1).
(a) Magnetic resonance imaging (MRI; T2 weighted coronal image) showing the absence of the biceps femoris tendon (arrow head). (b) MRI (T2 weighted coronal image) showing the popliteus muscle tendon rupture at the femoral attachment (arrow head). (c) MRI (T2 weighted coronal image) showing the lateral collateral ligament (LCL) rupture at the fibula head (arrow head) and substance of the LCL (arrow). (d) MRI (T2 weighted sagittal image) showing the anterior cruciate ligament rupture (arrow head).

Magnetic resonance imaging showed evidence of a complete anterior cruciate ligament (ACL) rupture, PLC injury that included injury to the popliteus and LCL, and distal rupture of the biceps femoris (Figures 2(a)-2(d)).
(a) There was evidence of contusion of the common peroneal nerve, and the patient underwent neurolysis (arrow head). (b) There were complete avulsions of the lateral collateral ligament (arrow), popliteofibular ligament (white arrow), and biceps femoris (star) from the fibula head; avulsion of the popliteus muscle tendon from the femoral condyle had also occurred (black arrow).

There was evidence of contusion, and the patient underwent neurolysis (Figures 3(a) and 3(b)).
Anatomical single bundle anterior cruciate ligament reconstruction with the ipsilateral semitendinosus tendon was performed.

fig4
Because of improved ADL, an anatomical single bundle ACL reconstruction was performed (Figure 4).
At the final follow-up, 31 months after the injury, there was excellent knee range of motion (5 -0 -145 ), stability of the knee, and muscle strength.

There was excellent knee ROM (5 -0 -145 ) and muscle strength, and he returned to competition 27 months after the injury (Figure 5).
