Diagnostic and Therapeutic Shoulder Arthroscopy Using a Small-Bore Needle Arthroscope.

As resolution and image quality improve, several potential advantages make needle arthroscopy (NA) appealing for broader therapeutic applications in the operating room. Smaller camera size and weight allow for a minimally invasive approach with smaller incisions than standard arthroscopy and decreased use of arthroscopic fluid. Differences in the technology, such as a 0° optic and less rigid instrumentation, necessitate a modified technique to accommodate thorough diagnostic arthroscopy as well as modified approaches to therapeutic procedures. This article introduces our preferred approach to diagnostic arthroscopy of the glenohumeral joint and subacromial space with needle arthroscopy and small-bore instruments. This technique could increase efficiency and decrease operative time with certain arthroscopic procedures, and it may improve patient outcomes.
