Sensory testing for the left foot revealed irregular deficits mainly in deep peroneal with close to complete weakness for dorsiflexion and forefoot eversion, and some weakness for inversion also. Palpation and percussion proved for positive Tinel's at and just below the level of the fibular head, but not above the fibular head in the popliteal fossa. According to his examination and history, it was possible that the disruption of the knee associated with the injury had led to some ongoing entrapment of the peroneal nerve at the knee.
