Abstract
Summary: Arthroscopy of the hip joint has evolved at a slower pace compared with other major joints. A few champions of the procedure developed surgical techniques and designed adequate instrumentation and traction devices. Indications evolve as more understanding and experience in hip arthroscopy is gained around the world. A precise knowledge of portal anatomy and surface topography is important to enter the hip joint arthroscopically. The greatest development was the introduction of cannulated instruments that follow a flexible guide wire into the joint. These guide wires are previously placed in the joint through long needles under fluoroscopic control; this technique became a standard for all modern hip arthroscopy sets. Good patient positioning either supine or lateral with adequate traction to separate the joint space is mandatory. New developments like slotted cannulas that allow for angled or curved instruments to be inserted in the joint increase the versatility of the procedure. Aiming devices help in safer and faster portal establishment, especially in the case of the anterior portal. The surgeon who is determined to start arthroscopic surgery of the hip should follow the established surgical technique and have adequate infrastructure and specially designed instruments for the procedure.
