## Narrative

The employee was standing on a wooden pallet lifting a 60 lb. sample box and dumping it into a tote. One of the pallet slats broke, causing the employee to lose his balance. The sample box he was lifting struck his left leg just above the knee, causing his knee to bend backwards, resulting in a sprain to his left knee.
