Hip Arthroscopy - State of the Art in 2018.

The field of hip arthroscopy has undergone considerable change in the past 25 years and continues to evolve at a rapid pace. Lessons from the early complications and challenges of hip arthroscopy have led to improved safety and refinement of instrumentation and techniques. The pathophysiology of hip injuries is better understood, and advances in surgical technique have helped expand indications, particularly as a shift from pathology resection to anatomic repair and reconstructive procedures has occurred. As the field has progressed, longitudinal outcome studies are now available to help judge efficacy. The purpose of this review is to highlight the past 30 years of hip arthroscopy, the current practice trends, and future directions of the field.
