Abstract
Hip arthroscopy is the predominant surgical procedure for the treatment of femoroacetabular impingement syndrome (FAI). Usually, hip arthroscopy requires intraoperative fluoroscopic guidance for portal establishment, acetabuloplasty, suture anchor placement, and femoroplasty, which has disadvantages such as radiation exposure and prolonged operative time. This article presents a technique of hip arthroscopy without fluoroscopy throughout. By establishing portals through a semiopen hollow guide bar, "one-line trimming" for pincer deformity removal, modified distal anterolateral portal for anchor placement, "triangular abrasion" for cam deformity resection, and intraoperative dynamic examination to ensure adequate relief of impingement, we provide a safe and effective surgical procedure for hip arthroscopy to treat FAI without fluoroscopy.
