Understanding the Remplissage: History, Biomechanics, Outcomes, and Current Indications.

Abstract

Purpose of review: Arthroscopic remplissage has continued to gain popularity as an adjunct to Bankart repair for patients with anterior shoulder instability. Although the original remplissage technique was described over 15 years ago, our understanding of when and how to use this procedure continues to evolve. This article provides a review of how remplissage affects shoulder biomechanics, compares clinical outcomes between remplissage and other procedures for shoulder instability, and discusses current indications for remplissage.

Recent findings: Current research focuses on the use of remplissage across a wide range of glenoid bone loss. Remplissage appears effective at preventing recurrent instability in patients with glenoid bone loss up to 15% of the glenoid width. However, once glenoid bone exceeds 15%, outcomes tend to favor bony reconstruction procedures such as Latarjet. Results of biomechanical studies examining shoulder range of motion (ROM) after remplissage are mixed, though clinical studies tend to report no significant limitations in ROM when remplissage is added to a Bankart repair. Adding a remplissage to conventional Bankart repair may improve clinical outcomes and lower rates of recurrent instability without significantly altering shoulder ROM. However, surgeons should recognize its limitations in treating patients with large amounts of glenoid bone loss and should be prepared to discuss alternative procedures on a case-by-case basis. Absolute indications and contraindications for remplissage are not well defined currently and require further scientific research.
