Abstract
Subacromial decompression with acromioplasty is among the most commonly performed shoulder procedures. The advantages of in-office nano-arthroscopy include the capability of diagnosing and treating subacromial impingement, swifter patient recovery, improved cost-effectiveness, and superior patient satisfaction. The purpose of this technical report is to describe our technique for performing in-office nano-arthroscopy for subacromial decompression (subacromial bursectomy and acromioplasty), with a particular focus on appropriate indications, providing sufficient local anesthesia, optimizing visualization, and discussing the advantages of the in-office setting compared to the operating room.
