Biomechanical Validation of Load-Sharing Rip-Stop Fixation for the Repair of Tissue-Deficient Rotator Cuff Tears.

The article discusses a study which compared the strength of the load-sharing rip-stop (LSRS) construct to that of single-row fixation for rotator cuff repair. It cites the creation of rotator cuff tears in 6 cadaveric matched-pair specimens and their repair with a single row or an LSRS. The results showed that the ultimate failure load of the LSRS construct for rotator cuff repair was 1.7 times that of a single-row construct in a cadaveric model.
