Foot and Ankle Surgery

We propose a unique arthroscopic technique, the "hanger-lifting procedure." Unlike conventional arthroscopy, the space in which the arthroscope is placed is not a joint space filled with water but a subcutaneous space filled with air. The space is kept lifted by a semi-loop-shaped hanger and a retraction system by use of a wire. In general, arthroscopes are unable to be applied outside the joint because of the lack of a cavity. However, this method can provide extra-articular visualization of the knee in addition to standard intra-articular visualization. This approach is useful for lateral release of the knee extensor and bipartite patellae, allowing direct vision from both outside and inside the joint. One possible complication is subcutaneous effusion or interstitial edema. Compressive dressings should be applied to prevent subcutaneous effusion after surgery. However, the combination of conventional arthroscopy by use of saline solution and the hanger-lifting technique by use of air arthroscopy can provide an excellent view inside and outside the joint. This technique may continue to evolve, and although some points in the technique can be improved, this method is useful in joint surgeries.
