Several surgical procedures have been proposed to address anterior glenohumeral instability, which is one of the most common complaints in the general population. The remplissage, first described in early 2000s, is a procedure performed simultaneously with the arthroscopic Bankart repair to correct large, engaging Hill-Sachs lesions (HSLs). This procedure stabilizes the joint by tenodesing the infraspinatus tendon into the HSL to fill and disengage the defect. This procedure gained popularity because it has relatively low risk and is able to improve shoulder stability while being less invasive than other bone-blocking procedures. The remplissage has become a valuable add-on technique that can substantially improve outcomes in unstable patients undergoing arthroscopic Bankart repair. Nevertheless, several studies in the literature have raised concerns regarding its efficacy in critically unstable patients and the potential range of motion limitations that can arise postoperatively. Additional comparative studies and trials should be conducted to appropriately establish the role of remplissage in treating anterior instability, especially in patients with critical bone loss.
