May be tendon tear: Based on the history you provided you may have sustained a tendon injury. An examination by a foot and ankle specialist is in order with an MRI examination likely to be ordered. The anterior tibial tendon is a major dorsiflexor of the foot. Without it functioning properly you would likely suffer a foot drop. There are other causes of foot drop and these should be ruled out.
