Use of a Hip Arthroscopy Flexible Radiofrequency Device for Capsular Release in Frozen Shoulder

Abstract Adhesive capsulitis is a common and challenging condition to treat. Arthroscopic capsular release is usually contemplated when conservative treatment fails or when there is severe and/or chronic loss of range of motion. This procedure can be difficult to perform because of difficult access to the joint, poor visualization, and loss of working space from retraction of the joint capsule. The articular surfaces and the axillary nerve are also at higher risk of injury. Arthroscopic scissors, shavers, and electrocautery are typically used to perform the capsular release. To perform a safer and more precise arthroscopic shoulder capsular release, a creative and innovative use of a flexible hip arthroscopy radiofrequency ablator is described.
