Study information

Scientific title

All-arthroscopic versus mini-open repair of small or moderate sized rotator cuff tears: a randomised controlled trial using conventional and expertise-based designs



Study hypothesis

To compare the effectiveness of all-arthroscopic to mini-open rotator cuff repair to improve the quality of life, as measured by the Western Ontario Rotator Cuff (WORC) Index, in patients with a small or medium-sized rotator cuff tear.

Drug names

Primary outcome measure

Quality of life based on the validated self report assessment tool Western Ontario Rotator Cuff index (WORC), measured at baseline, at 6 weeks, 3, 6, 12, 18 and 24 months post-operatively.

Secondary outcome measures

1. Biological integrity of repair based on MRI, measured at baseline and 12 months post-operatively
2. Surgical complications monitoring, measured at baseline, at 6 weeks, 3, 6, 12, 18 and 24 months post-operatively
3. Adverse events reporting, measured at baseline, at 6 weeks, 3, 6, 12, 18 and 24 months post-operatively
4. Physical impairment assessments including:
4.1. Range of Motion (ROM) Assessment Scale, measured at baseline, at 6 weeks, 3, 6, 12, 18 and 24 months post-operatively
4.2. Strength (measured using a hand held dynamometer and scale), measured at baseline, at 6 weeks, 3, 6, 12, 18 and 24 months post-operatively
4.3. Composite Impairment Score, measured at baseline, at 6 weeks, 3, 6, 12, 18 and 24 months post-operatively
5. Pain/Disability: Shoulder Pain and Disability Index (SPADI) pain scale self report, measured at baseline, at 6 weeks, 3, 6, 12, 18 and 24 months post-operatively
6. General health: 12-item Short Form health survey (SF-12), measured at baseline, at 6 weeks, 3, 6, 12, 18 and 24 months post-operatively
7. Work limitations: measured using two self-report measures, measured at baseline, at 6 weeks, 3, 6, 12, 18 and 24 months post-operatively

Participant inclusion criteria

1. Male or female patients
2. Aged 18 - 75 years

Target number of participants


Participant exclusion criteria

Pre-operative exclusion criteria:
1. Evidence of major joint trauma, infection, avascular necrosis, chronic dislocation, inflammatory or degenerative glenohumeral arthropathy, frozen shoulder or previous surgery of the affected shoulder
2. Evidence of significant cuff arthropathy with superior humeral translation and acromial erosion diagnosed by x-ray or other investigations
3. Major medical illness (life expectancy less then two years or unacceptably high operative risk)
4. Unable to speak or read English
5. Psychiatric illness that precludes informed consent
6. Unwilling to be followed for two years

Intra-operative exclusion criteria:
7. Large, massive, or irreparable cuff tears, extending into the subscapularis or teres minor which cannot be mobilised to the articular margin or repaired with both techniques
8. Teres minor or subscapularis tears
9. Inelastic and immobile tendon, which cannot be advanced to articular margin
10. Co-existing labral pathologies requiring repair with sutures (superior labrum anterior posterior [SLAP] II - IV), Bankart lesions requiring repair, partial tears of biceps (more than 60% of thickness) requiring tenodesis or release

MRI exclusion criteria:
11. History of head or eye injury involving metal fragments
12. Ever worked in a metal shop or been a soldier
13. Presence of implanted electrical device (such as a cardiac pacemaker)
14. Severe heart disease (including susceptibility to arrhythmias)
15. Metal braces on teeth
16. Pregnancy
17. Presence of intrauterine device
