简要总结
Rotator cuff tear is the leading cause of shoulder pain in the elderly. There isn't enough evidence nor clinical guidelines to guide the treatment of massive rotator cuff tears, specially irreparable tears. Arthroscopic partial repair has been widely used and superior capsular reconstruction (SCR), either with allograft, autograft or augmentation with long head biceps brachii tendon (LHBBT), has been recently added. It is showing promising results, but lacking high quality evidence.
This is a prospective clinical study to compare the outcomes of different surgical methods for massive rotator cuff tendon tears. Minimal follow-up time will be two years. In this trial, massive rotator cuff tears will be anatomically repaired if possible. For irreparable tears a method will be randomly assigned intra-operatively once a tear is determined to be irreparable - either partial repair or partial repair with superior capsular reconstruction using the long head biceps brachii (LHBB) tendon. Patients who are eligible for the study but refuse operative treatment, will serve as conservative study group.
The hypothesis is that massive rotator cuff tears that are reparable will have the best functional outcomes. For irreparable tears, augmentation with LHBBT will give superior results over partial repair.
详细描述
Patients with massive rotator cuff tendon tears aged between 50 to 80 years will be included in the study following the eligibility criteria. Massive tear is defined as grade III tear according to Davidson and Burkhart classification (2010), supraspinatus (SSP) tendon retraction described by Patte (1990) classification.
The study is conducted in Tartu University Hospital Sports Traumatology Centre and rotator cuff repair procedures will be done by three orthopaedic surgeons with long experience in arthroscopic shoulder surgery.
It is determined intra-operatively whether the tear is reparable or not. If possible, the tendon(s) will be anatomically repaired. For irreparable tears intra-operative urn randomization takes place - either partial repair or partial repair with SCR using the LHBB tendon. Surgical techniques will be standardized. Patients who refuse operative treatment, will be followed as conservative treatment group.
The primary objective of the study is the functional status of the included subjects in different treatment groups. The secondary objective of the study is to confirm whether the tendons are intact on follow-up magnetic resonance imaging (MRI) 6 months, 12 months and 24 months after operation using Sugaya classification (2007).
The post-operative therapy regimen will be the same for each study group. Subjects will come for scheduled visits at 6-month, 12-month, and 24-month timepoints. Assessment tools consist of range of motion (ROM), strength measurements, preoperative radiography measuring acromio-humeral index (AHI), critical shoulder angle (CSA), acromion type and shoulder arthrosis (Hamada), functional scores: The Disabilities of the Arm, Shoulder and Hand (DASH), The Constant-Murley score (CMS), The American Shoulder and Elbow Surgeons (ASES) and visual analogue scale (VAS), also including Tampa kinesiophobia score and emotional well-being (EEK) score. Goutallier classification (1994) will be used pre- and postoperatively to measure muscle fatty infiltration.

Arthroscopic rotator cuff partial repair with superior capsule augmentation with LHBBT
If a tear is intra-operatively determined irreparable, randomization takes place.
Irreparable tears that are randomly selected to receive arthroscopic rotator cuff partial repair including superior capsular augmentation with proximal part of the long head of the biceps tendon. The long head of the biceps tendon will be released from bicipital groove and proximal part of the tendon will be used to cover the rotator cuff gap and anchored to the greater tuberosity.

结局指标
主要结局
Functional outcome according to the Constant-Murley score (CMS).
时间窗: Pre-operative baseline, 6-months, 12-months and 24-months follow-up visit
Measured by the change in joint functional score. The higher the score, the higher the quality of the function. The test is divided into four subscales: pain (15 points), activities of daily living (ADL) (20 points), strength (25 points) and range of motion: forward elevation, external rotation, abduction and internal rotation of the shoulder (40 points).
Functional outcome according to the Disabilities of the Arm, Shoulder and Hand (DASH).
时间窗: Pre-operative baseline, 6-months, 12-months and 24-months follow-up visit
Measured by the change in joint functional score. The higher the score, the more severe disability. 30-item self-report questionnaire designed to assess symptoms and function of the entire upper extremity. Total scores range from 0 (minimum) to (100) maximum.
Change in shoulder strength
时间窗: Pre-operative baseline, 6-months, 12-months and 24-months follow-up visit
Measured by the change in rotator cuff strength isokinetic testing (abduction, internal and external rotation).
Functional outcome according to the American Shoulder and Elbow Surgeons (ASES) score.
时间窗: Pre-operative baseline, 6-months, 12-months and 24-months follow-up visit
Measured by the change in joint functional score. The higher the score, the better the outcome. The patient self-assessment (pASES) includes 6 pain items and 10 functional items that are shoulder specific (Angst, 2008). The pASES form has 3 sections: pain, instability, activities of daily living (ADLs) (Goldhahn, 2008). Pain section: 4 questions with yes/no responses, 1 question covering number of pain tablets per day, and a VAS (visual analogue scale) from 0 (no pain) to 10 (worst pain). Instability section: 2 questions (1. Response yes/no about feelings of instability, 2. Quantify instability from 0 (stable) to 10 (very unstable)). Activities of daily living (ADLs): Each shoulder is included (affected/non affected), 10 items, with a 4 point ordinal scale, range: 0 (unable to perform activity) to 3 (no difficulty in doing activity) (Goldhahn 2008).
