Plain English Summary

Background and study aims
Rotator cuff tears (injury to the muscle or tendons which stabilise the shoulder) are one of the most common conditions affecting the shoulder. Small and medium sized rotator cuff tears can be managed with arthroscopic or keyhole surgery. Very large or massive tears are difficult to operate on and often have poor rates of healing. As a result surgeons have investigated the use of products to improve the outcome of surgery on massive tears. We are testing a new product, called a patch, that we hope will improve the outcome of surgery for massive rotator cuff tears. The patch provides a scaffold to support the muscles of the rotator cuff. Studies of rotator cuff surgery using similar patches have found that recovery is improved and there is a lower rate of post-surgical problems. Here, we will look at the effect of the patch on the muscles in the shoulder and to look at whether using the patch improves pain and the clinical function of the shoulder after surgery.

Who can participate?
Participants who are at least 18 years old and with massive rotator cuff tears

What does the study involve?
Participants decide, together with their surgeon, whether to have patch-assisted surgery or standard treatment (either standard surgery or non-surgical management, which involves physiotherapy). They have a magnetic resonance scan of their shoulder to look at the muscle damage in the shoulder before and after their treatment. This will help us to understand how the patch works. We also ask participants to fill in some questionnaires about their shoulder function and pain, before and after their treatment. The outcomes of this study will help us to design a larger trial to determine the most effective method for treating massive rotator cuff tears.

What are the possible benefits and risks of participating?
There is no direct benefit to people taking part in the study. However, we hope this study will provide information to help improve future treatment of massive rotator cuff tears. There are no direct risks to taking part in study. No medications, including analgesics or anti−inflammatories, will be withheld and treatment (surgery or physiotherapy) will not be delayed in any way. Participants will have an MRI scan which can be claustrophobic, but the scan can be stopped at any time if the participant is not happy. MRI scans are very safe and give no radiation.

Scientific title

Shoulder PAtch for Rotator Cuff tears: An exploratory study



Study hypothesis

Use of a synthetic graft to augment rotator cuff repairs will provide better improvement of clinical function of the shoulder compared to conservative treatment.

Study design

This is an exploratory study of 60 people with massive rotator cuff tears who will undergo either conservative treatment (standard surgery / non-surgical management) or patch-assisted surgery.

Massive rotator cuff tears


Patients will either undergo augmented patch-assisted rotator cuff repair or conservative treatment, which may include standard surgery or non-surgical management. Treatment decision will be made by the surgeon together with the patient.

Intervention type


Not Applicable

Drug names

Primary outcome measures

Clinical outcomes (baseline, 6 weeks, 6 months):
1. Clinical examination
2. Shoulder function and pain - Oxford Shoulder Score, Shoulder Pain and Disability Index [SPADI], Constant Score
3. Quality of life - EQ5D
Imaging outcomes
1. MRI assessment of the supraspinatus, infraspinatous and subscapularis at baseline (pre-surgery) and 6 months post-surgery : Muscle volume, Goutallier score of muscle atrophy and fatty infiltration

Secondary outcome measures

This is an exploratory study, therefore there are no defined primary and secondary outcome measures
