This booklet is intended as an insightful update on daily shoulder management closely based on the content of closed consensus meetings of the International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine (ISAKOS) Upper Extremity Committee (UEC). Section A provides a comprehensive review of the currently available classifications and outcome scores for shoulder disorders, illustrating their potential pitfalls and limitations. The authors emphasize the need for standardization of shoulder assessment and propose two novel classifications that are expected to facilitate tailoring of management. Section B describes pioneering techniques to re-establish shoulder function after dislocation of the acromio-clavicular joint and covers surgical indications and decision-making criteria. Section C describes the current state of evidence concerning rotator cuff disorders, providing novel theories regarding the underlying biomechanics and reconstruction techniques.

Rotator cuff surgery is currently the most common surgical procedure involving the shoulder. Unfortunately despite major technical advances, there is still a significant rate of failure of primary rotator cuff repair, ranging from 10% to 40%. This book describes the diagnosis, classification, assessment, and management of failed rotator cuff repairs. It also explores the etiology of the failed repairs, presents a series of treatment options, and discusses the complications. In a multidisciplinary format it addresses both how to prevent failure and how to diagnose and manage the failed rotator cuff, including imaging, laboratory testing, nutrition, surgery and rehabilitation. This comprehensive book, published in collaboration with ISAKOS, appeals to all stakeholders in orthopedic medicine and surgery.
