In the latter case, congenital deficiency of the superior peroneal retinaculum and a shallow fibular groove may play a role.
Primary repair of the superior peroneal retinaculum (4-6,11) is feasible if the remaining retinaculum available to cover the tendons is sufficient.
The superior peroneal retinaculum is normally thin and deficient, especially anteriorly.
