Advancing Regenerative Surgery in Orthopaedic Sports Medicine

Abstract

The constant desire to improve outcomes in orthopaedic sports medicine requires us to continuously consider the challenges faced in the surgical repair or reconstruction of soft tissue and cartilaginous injury. In many cases, surgical efforts targeted at restoring normal anatomy and functional status are ultimately impaired by the biological aspect of the natural history of these injuries, which acts as an obstacle to a satisfactory repair process after surgery. The clinical management of sports injuries and the delivery of appropriate surgical intervention are continuously evolving, and it is likely that the principles of regenerative medicine will have an increasing effect in this specialized field of orthopaedic practice going forward. Ongoing advances in arthroscopy and related surgical techniques should facilitate this process. In contrast to the concept of engineered replacement of entire tissues, it is probable that the earliest effect of regenerative strategies seen in clinical practice will involve biological augmentation of current operative techniques via a synergistic process that might be best considered “regenerative surgery.” This article provides an overview of the principles of regenerative surgery in cartilage repair and related areas of orthopaedic surgery sports medicine. The possibilities and challenges of a gradual yet potential paradigm shift in treatment through the increased use of biological augmentation are considered. The translational process and critical role to be played by the specialist surgeon are also addressed. We conclude that increased understanding of the potential and challenges of regenerative surgery should allow those specializing in orthopaedic surgery sports medicine to lead the way in advancing the frontiers of biological strategies to enhance modern clinical care in an evidence-based manner.
