Augmentation techniques for rotator cuff repair.
BACKGROUND
There is a high rate of recurrence of tear and failed healing after rotator cuff repair. Several strategies have proposed to augment rotator cuff repairs to improve postoperative outcome and shoulder performance. We systematically review the literature on clinical outcome following rotator cuff augmentation.


METHODS
We performed a comprehensive search of Medline, CINAHL, Embase and the Cochrane Central Registry of Controlled Trials, from inception of the database to 20 June 2012, using various combinations of keywords. The reference lists of the previously selected articles were then examined by hand. Only studies focusing on clinical outcomes of human patients who had undergone augmented rotator cuff repair were selected. We then evaluated the methodological quality of each article using the Coleman methodology score (CMS), a 10 criteria scoring list assessing the methodological quality of the selected studies (CMS).


RESULTS
Thirty-two articles were included in the present review. Two were retrospective studies, and 30 were prospective. Biologic, synthetic and cellular devices were used in 24, 7 and 1 studies, respectively. The mean modified Coleman methodology score was 64.0.


RESULTS
Heterogeneity of the clinical outcome scores makes it difficult to compare different studies.


CONCLUSIONS
None of the augmentation devices available is without problems, and each one presents intrinsic weaknesses. There is no dramatic increase in clinical and functional assessment after augmented procedures, especially if compared with control groups.


METHODS
More and better scientific evidence is necessary to use augmentation of rotator cuff repairs in routine clinical practice.
