Diagnostic and Therapeutic Elbow Arthroscopy Using Small-Bore Needle Arthroscopy.

Abstract

Needle arthroscopy may provide several potential advantages over standard arthroscopy. The smaller camera size and weight allows for a minimally invasive and percutaneous approach with decreased fluid use. As resolution and image quality improve, the potential to expand clinical use for therapeutic applications becomes possible. One promising use is in elbow arthroscopy. Difference in the technology, such as a zero-degree optic and less-rigid instrumentation, necessitate a modified technique to accommodate thorough diagnostic arthroscopy and therapeutic procedures. This manuscript introduces the authors' approach to diagnostic needle arthroscopy of the anterior and posterior elbow compartments and placement of therapeutic instrumentation. This technique could theoretically decrease the risk of iatrogenic neurovascular injuries, reduce postoperative swelling and pain due to decreased fluid use, and potentially lead to faster recovery.
