Introduction:
Our technique of arthroscopic capsular release involving two posterior portals and one anterior portal, to accomplish a complete 360° release, improves motion and reduces pain in patients with idiopathic adhesive capsulitis.
Step 1 Position The Patient:
Place the patient in a beach-chair position for shoulder joint arthroscopy.
Step 2 Establish A Routine Posterior Glenohumeral Joint Arthroscopy Portal:
Use a routine posterior glenohumeral arthroscopy portal to introduce the arthroscope.
Step 3 Establish An Anterior Portal:
Establish the anterior portal under direct vision using a spinal needle.
Step 4 Release The Rotator Cuff Interval And Subscapularis Tendon:
Release the rotator cuff interval, dividing no more than the upper half of the intra-articular subscapularis tendon.
Step 5 Release The Anterior-Inferior Aspect Of The Capsule:
Cut the anterior-inferior aspect of the capsule completely.
Step 6 Establish A Posterior-Inferior Portal:
Determine the location of the posterior-inferior portal with a spinal needle.
Step 7 Release The Posterior-Inferior Aspect Of The Capsule:
Release or perforate the posterior-inferior capsule of the joint with the arthroscopic wand.
Step 8 Gently Manipulate The Arm:
Manipulate the arm in abduction, then forward and backward flexion, and then external and internal rotation.
Results:
An arthroscopic capsular release with use of the technique described here was performed in forty-nine shoulders in forty-three patients with idiopathic adhesive capsulitis4.
