This document discusses the surgical management of shoulder stiffness. It notes that 89.5% of cases can be treated non-operatively, while 10% may require release within 12 months. The main options for surgeons are manipulation under anesthesia (MUA) and arthroscopic capsular release. MUA involves manually moving the joint to break up adhesions, while arthroscopic release allows visual inspection and cutting of restrictive tissue. Both have advantages and disadvantages, and arthroscopic release aims to precisely release the capsule under direct visualization.
