With arthroscopic Bankart repair rising in popularity for the treatment of shoulder instability, recurrent instability is a relevant complication with an incidence of approximately 13%. Yet, management in the revision situation still is a challenge in the absence of established evidence-based treatment guidelines. With an often multifactorial etiology including soft-tissue based factors such as hyperlaxity or special capsulolabral and ligamentous lesion configurations, bone based factors including glenoid bone loss or glenoid track lesions, technical factors or functional demand-specific factors related to failure, a concise evaluation including a thorough clinical and radiographic assessment is essential. The surgical portfolio in the situation of failed arthroscopic repair includes revision of soft-tissue stabilization with or without arthroscopic adjunct procedures or bone-based augmentation in anatomic or non-anatomic technique. This chapter focuses on providing a practical guideline in the clinical assessment, decision-making and surgical management of a failed soft-tissue repair situation.
