Round 1

Reviewer 1 Report

Introduction

1. I am missing a perspective regarding a research background at the end of this section. I would recommend adding a brief perspective before the aim. Then, it should be a clear message for the reader.

2. According to the previous comment, add also some reference and statments due to your hypothesis.

 

Materials and methods

1. How many patients were evaluated in this study? Add demographic and anthropometric information, with inclusion and exclusion criteria.

Conclusion

1. Please add some conclusions to this section. The statement you used is an observation and not a conclusion.

Reviewer 2 Report

Thanks for  letting me review the current manuscript  which conclude that:” Biologic augmentation of revision RCR by combination of microfracture, collagen 297 patch graft and subacromial injections of platelet concentrate is an effective strategy in 298 improving tendon healing rate.”.

Interesting manuscript, I do however have some concerns, which could have improve the manuscript.

1.       As MRI was conducted, it should have been with contrast to investigate the possibility of leakage through the cuff.

2.       There is little information on the retear rate in the control group, as written in the manuscript this is found to reduce the numbers of re-tears. I would  like to know how the result in the control group match those published previously to ensure that the comparison between the groups are based on correct para meters.
