Trial Outcomes & Findings for Prospective Randomized Comparative Study of Outcome of Subscapularis Tear (NCT NCT01996904)

NCT ID: NCT01996904

Last Updated: 2014-03-12

Results Overview

The ASES is a 100-point scale which is divided in two sections. Fifty points of which are derived from patient self-report of pain and the other 50 points of which are computed from a formula using the cumulative score of 10 activities of daily living .The item related to pain is evaluated by a VAS (10 cm) that ranges from 0 (no pain at all) to 10 (pain as bad as it can be). The ten activities of daily living include skills such as putting on a coat, sleeping on the affected side, wash back/do up bra in back, manage toileting, combing one's hair, reach a high shelf, lift 10lbs above shoulder,throw a ball overhand,do usual work and do usual sport.The items related to function are evaluated by a four-point Likert scale. The scores of the pain and function subsections are transformed in percentages and each one represents 50% of the final score, which can range from 0 (absence of function) to 100 (normal function).

Participant Flow

* March 2009 to October 2010 * Out-patient department * Consecutive patients diagnosed with full thickness supraspinatus tear preoperative thru MRI * Underwent arthroscopic repair or debridement for rotator cuff tear

A total of 256 patients were initially identified to have subscapularis tear. They were then enrolled and all randomized. By the twenty-fourth month outcome assessment and ultrasound evaluation, 65 were lost to follow-up. 38 from group A and 27 from group B. Thus, only 191 patients making the final number of participants. .

Measure
Arthroscopic Repair
Lateral-anterosuperior portal ("Miracle Portal") was used to repair subscapularis tendon. Bursa anterior to the subscapularis tendon was usually removed for the accurate positioning of the suture-hook. Subscapularis tendon was released, pulled and sutured with suture-hook. One or two suture anchors of Modified Mason-Allen technique was used to secure the tendon. If the subscapularis tendon was not sufficiently mobile, further anterior interval release between subscapularis and scapula was performed. LHB (long head of biceps tendon) was either treated with a biceps tenodesis or by tenotomy when there was tear or subluxation of it. The footprint area of the subscapularis tendon, which is trapezoidal in shape on the proximal part of the lesser tuberosity, was thoroughly cleaned of soft tissue and meticulous bone preparation was done prior to placement of anchor sutures.
Arthroscopic Debridement
Anterosuperior portal was made for debridement (capsulectomy and anterior bursectomy). A systematic release of the glenohumeral ligaments and the overlying subscapularis bursa was also performed. The superior aspect of the tendon was freed from the surrounding structures (the coracohumeral and superior glenohumeral ligaments). The middle glenohumeral ligament was always released to identify the upper border of the subscapularis tendon.

SECONDARY outcome

Timeframe: every three months after the surgery until the 24th month

US is a diagnostic imaging technique used to visualise deep structures of the body by recording the echoes of pulsed ultrasonic waves directed into the tissues and reflected by tissue planes to the transducer. These echoes are converted into 'pictures' of the tissues under examination. It consists of a non-invasive examination that has practically no adverse effects and allows dynamic visualisation of the tendons during movement of the shoulder.
