Dry Arthroscopy of the Elbow.

Dry arthroscopy is attractive because it affords an unsurpassed clarity of view and minimizes swelling. The elbow is a challenging joint to assess arthroscopically; however, dry arthroscopy has some particular benefits in the elbow. The primary benefit is the quality of the tissue definition, but dry arthroscopy also increases the working time for surgery by reducing swelling and results in less postoperative discomfort for the patient. With dry arthroscopy, all joint surfaces are covered in synovial fluid, which reflects light, to provide a clearer image of the joint surfaces and depth of field. The air-fluid interface provides an uninterrupted appreciation of the synovial recesses and tissue perfusion. This article describes the technique and indications for dry elbow arthroscopy, which will allow other surgeons to reap the benefits of dry arthroscopy without the need for special equipment or changes in their basic technique.
