Arthroscopic Resection of Too-Long Anterior Process (TLAP) of the Calcaneus, Anterior Subtalar Synovectomy, Debridement of the Sinus Tarsi, and Posterior Subtalar Adhesiolysis Via Anterolateral Subtalar and Dorsolateral Midtarsal Portals

Lateral heel pain can have numerous causes and many of them are intra-articular pathologies of the anterior and posterior subtalar joint. Frequently, there is not a single pathology that account for the lateral heel pain and combination of different pathologies can occur. Symptomatic too-long anterior process of the calcaneus, sinus tarsi syndrome, and subtalar arthrofibrosis can be precipitated by repeated sprain. Cases recalcitrant to conservative treatment are indicated for surgery. The purpose of this Technical Note is to report a 2-portal arthroscopic approach to address these pathologies.
