Anterior shoulder instability with Bankart lesion and associated posterior humeral head injury (Hill–Sachs) is common in athletes. Several treatments have been proposed for the management of the Hill–Sachs lesion, from bone grafts or rotation osteotomies to capsulotendinous interposition, such as remplissage. This procedure has been shown to be safe and effective in increasing glenohumeral stability. However, the correct indication concerning the bone defect and its effects in terms of range of motion and function, especially in highly demanding patients, is still debated. This narrative review aims to present the current state-of-the-art of the posterior capsulotenodesis in association with Bankart repair, for treating anterior shoulder instability in competitive athletes.
