Although the preferred method for lateral ankle ligament reconstruction has been the Brostrom-Gould technique, which achieves ligament repair/shortening with advancement of the inferior extensor retinaculum, there is increasing evidence that arthroscopic examination at the same time may be beneficial.
The first is placed distal to the anterior inferior fibula, through the inferior extensor retinaculum and capsule.
The deep peroneal nerve can become compressed in the fibro-osseous tunnel underneath the inferior extensor retinaculum.
The lateral root of the inferior extensor retinaculum originates superficial to the peroneal tendons and inserts on the lateral aspect of the anterior process of the calcaneus.
The intermediate layer has two components: the intermediate root of the inferior extensor retinaculum and the cervical ligament.
Finally, the deep layer of the lateral ligamentous complex contains the medial root of the inferior extensor retinaculum, which courses more deeply in the sinus tarsi and sends attachments to both the talus and the calcaneus adjacent to the interosseous talocalcaneal ligament (IOL).
