Peroneal tendon subluxation often occurs because of sudden dorsiflexion of the ankle, leading to a traumatic rupture of the superior peroneal retinaculum. Currently, there are several surgical techniques to deepen the fibular groove, but there is no universally accepted gold standard. This technique article describes a fibular groove deepening with preservation of the fibrocartilage in conjunction with repair of the superior peroneal retinaculum. Addressing the main pathologies that may be leading to subluxation of the peroneal tendons, we offer an approach that avoids many of the common pitfalls from previously proposed techniques while preserving the natural fibrocartilage within the malleolar groove and repairing the retinaculum.
