In this book, leading international thinkers in the still nascent field of orthopaedic sports medicine consider what the future holds and give their views on what we should be most worried about. The range of issues addressed is wide, encompassing technological threats, environmental concerns, big data and its ramifications, the influence of industry, academic ethics, and much more. Many of the identified dangers are not yet on the popular radar, and these are the principal focus of the book. On the other hand, attention is also paid to misplaced fears, with explanation as to why these anxieties can be laid to rest.  The contributors are leading thinkers in the field and include original pioneers of sports medicine, senior and newly appointed orthopaedic surgeons, orthopaedic trainees, and sports medicine physicians. In addition, leaders of industry in sports medicine and allied health professionals from around the world share their fears. This compelling and thought-provoking book, published in collaboration with ISAKOS, will appeal to all stakeholders in orthopaedic sports medicine.
