Peroneus Longus Rupture at Its Origin Managed With Platelet Rich Plasma.

Tears of the peroneus longus muscle are unusual, and typically involve the distal insertion at the musculotendon junction. Although tears of the mid-portion of the peroneus longus muscle/tendon complex have been reported, no reports of a tear at the origin of the peroneus muscle have been published, to the authors' knowledge. Herein a case of proximal peroneus longus muscle tear and its subsequent management with platelet rich plasma is reported.
