This book has been designed to lead you through the first steps of the shoulder arthroscopy. Offering a companion guide, its numerous illustrations and videos support the text and aid in comprehension. The most common mistake in shoulder arthroscopy is to focus on the screen, whereas an external perspective is needed, though not always easy to achieve in practice. We recommend following the chronological order for the first techniques, which are then detailed one by one and can be read separately depending on the problem encountered. These techniques, all of which were developed by the author in the course of 20 years of arthroscopic surgeries, are characterized by their simplicity. After having mastered these techniques, the reader will have the basis needed to evolve on his or her own.
