Most peroneal tendon injuries are caused by the typical acute or recurrent lateral ankle sprain. As stated above, isolated injury to the peroneal tendons is rare.

  • Acute injury involves forceful dorsiflexion with contraction of the peroneal muscles or an inversion injury with a high load. Most acute injuries have subacute and chronic tendinopathy.

  • Chronic injury involves repeated inversion injuries, damage to the posterior talofibular and lateral malleolar retinaculum, and/or recurrent dislocation of the peroneal tendons, leading to chronic tears and lateral ankle instability. (See the image below.)
