The Dual-Fixed Slotted Cannula for Hip Arthroscopy: Surgical Technique

Joint access is crucial for hip arthroscopy success, yet current techniques-with or without the use of a cannula-fail to achieve optimal joint access. Current commercially available cannula options have many drawbacks, including limited range of movement of instruments, slow instrument changes, limited joint visualization, fluid outflow blockage, and potential for unintentional cartilage damage. In this article, we present a cannula concept for hip arthroscopy that addresses these limitations. The cannula's unique design includes slotted geometry and fixation deep to the capsule and superficially to the skin using a single capsular stay suture, allowing better control of instruments, improved visualization of the joint, faster instrument changes, a constant fluid outflow track, and a lower potential for cartilage damage.
