Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine if using BioBrace® to reconstruct the gap in the rotator cuff tears lead to better results for patients compared to the traditional maximal repair method. This study will use a variety of clinical, radiographic, and functional outcome measures. Specifically, the researchers will be comparing the re-tear rate, patient reported outcomes, shoulder strength, range of motion, muscle activation, in-vivo biomechanics, and other radiographic outcomes using x-ray and MRI.

Participants will be unaware to the type of surgery that they received. The investigator will not be blinded, however, the individuals assessing the outcomes will be.

Study Groups

Repair

This group will undergo a rotator cuff repair procedure.

Group Type ACTIVE_COMPARATOR

Repair

Intervention Type PROCEDURE

Patients in the maximal repair group will undergo a SCOI-row rotator cuff repair with adequate tension as described previously, with recreation of the rotator cable. Briefly, the SCOI-row rotator cuff repair uses one triple loaded suture anchor for each 1.2cm of torn tendon. This technique has been completed in a previous randomized controlled trial.

Bridging Reconstruction using BioBrace

This experimental group will undergo bridging reconstruction using the bioinductive implant, BioBrace.

Group Type EXPERIMENTAL

Bridging Reconstruction using BioBrace

Intervention Type PROCEDURE

Patients in the reconstruction group will undergo maximal repair with interposition bridging using BioBrace. This technique will follow a previously described technique by the principal investigator with differences allocated to the graft, it's preparation and insertion. The bursa will be debrided, and rotator cuff edged will be shaved down to stable tissue. BioBrace is bioinductive scaffold composed of highly porous type I collagen and bio-resorbable poly (L-lactide) (PLLA) microfilaments, and will be used as the graft in this trial.
