Single-Portal Arthroscopy of the Central Compartment of the Hip.

Since hip arthroscopy has become a standard of orthopaedic practice, the indications have continued to expand as it has proved to be a helpful diagnostic, as well as therapeutic, tool. Access to the hip joint, however, remains challenging for the orthopaedic surgeon who does not routinely perform hip arthroscopy. We present a single-portal arthroscopic technique, showing the feasibility of single-portal arthroscopic access to the hip joint, as well as describing basic indications and instrumentation for single-portal hip arthroscopy. Single-portal hip arthroscopy is ideal for the patient who needs to undergo diagnostic hip arthroscopy or for treatment in patients with simple hip pathology (e.g., removal of loose bodies or debridement).
