| 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 acronym | MvA RCT |
| Study objectives | 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. |

| Health condition(s) or problem(s) studied | Shoulder pain, rotator cuff tear |
| Intervention | Mini-open rotator cuff repair surgery versus all-arthroscopic rotator cuff repair surgery. |
| Intervention type | Other |
| Primary outcome measure(s) |
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. |
| Key secondary outcome measure(s) |
1. Biological integrity of repair based on MRI, measured at baseline and 12 months post-operatively |
