The frequency of partial rotator cuff tears is gradually increasing because of the advancements in imaging methods and arthroscopy techniques. One of the repair techniques is repair of the partial rotator cuff tear by conversion to a full-thickness tear. Another technique, the transtendon technique, has some practical challenges and risks. We attempted to develop a practical and easy technique with low morbidity to repair partial tears called the rotator cerclage technique.T he level of knowledge and the rate of establishing a distinctive diagnosis for partial rotator cuff tears have increased in line with widespread adoption of humeral arthroscopy and advanced magnetic resonance imaging methods. The best treatment plan for symptomatic partial rotator cuff tears remains uncertain. 1 Previously, debridementdboth with and without acromioplastydwas the standard treatment, 2,3 but this is being replaced by the repair of lesions in excess of 6 mm (grade 3) or those larger than 50% of the tendon thickness. 4 The most recent debate is inclined toward the conversion from a partial-to full-thickness tear and repair of the tear 5,6 or transtendon repair. 7,8 Both methods result in functional recovery and relief, but repairing the tear results in lower morbidity and earlier recovery whereas the tendon integrity, native footprint, and biomechanical properties (gapping and mean ultimate failure strength) are better in the case of transtendon repair, which keeps the bursal side intact. 9 The transtendon repair techniques described so far involve some challenges in surgical implementation and require experience. Our goal is to develop a practical technique with easy implementation through which a partial tear can be repaired through interventions performed only from the bursal side without converting the tear to a full-thickness tear after the partial tear is identified intra-articularly (Table 1).
TechniqueAfter induction of anesthesia, the patient is placed in the beach-chair position. A standard diagnostic arthroscopy is performed with 30 arthroscopic visualization through a posterior portal with a pump (FMS DUO Fluid Management System; DePuy Mitek, Raynham, MA) maintaining a pressure of 50 mm Hg. The supraspinatus insertion to the humerus is inspected in the neutral position with abduction and external rotation of the arm because most tears can be clearly seen at this position (Fig 1). After examination of all glenohumeral structures, the articular-sided supraspinatus tear is debrided with a 5-mm full-radius shaver (DePuy Mitek). The extent of the tear can be estimated based on the size of a shaver blade (the width of the articular side of the supraspinatus is estimated by comparing it with the known width of a 5-mm shaver) or with an arthroscopic ruler. Then, the surgeon inserts Prolene suture (Ethicon, Somerville, NJ) from an 18-gauge spinal needle stretching from the subacromial zone to the joint, ensuring that it passes from the supraspinatus articular tear area, and the Prolene suture proceeds inside the joi...
