Brief summary

The primary purpose of this research is to compare the images obtained by ultrasound between a standard repair of the subscapularis tissue and after repair with a Biobrace. The secondary purpose is to determine if there are any clinical differences.

Detailed description

The investigators would like to learn if subscapularis repair augmentation with the Biobrace in total shoulder arthroplasty (reverse and anatomic) will result in sonographic and/or clinical improvements. This will allow for improvements in technique and better outcomes for patients going forward.

Interventions

DEVICEBioBrace Augmentation

During shoulder replacement surgery, the subscapularis (rotator cuff muscle) is sometimes repaired back again. This will be stitched and augmented with a BioBrace. The Biobrace is a biocomposite scaffold meaning both synthetic and biologic, compared to other traditional implants that are either synthetic or biologic. The stitch in the BioBrace group will be anchored to and reinforced by this material.

PROCEDUREStandard Repair with Sutures

During shoulder replacement surgery, the Subscapularis (rotator cuff muscle) is sometimes repaired back again. This is usually repaired with stitches per standard of care treatment.

Masking description

The physician performing the ultrasound evaluation will be blinded to which treatment arm.

Intervention model description

Patients undergoing reverse shoulder arthroplasty will be recruited, consented, & enrolled. Patient will be randomized to standard repair with sutures versus standard repair with BioBrace augmentation of the repair.

Secondary

MeasureTime frameDescription
American Shoulder & Elbow Surgeons Score (ASES) score2 weeks, 3 months, 6 months, 1 year, 2 years after surgeryis a 100-point scale that consists of two dimensions: pain and activities of daily living. 0 indicates worse shoulder condition and 100 indicates best shoulder condition. The greater the score, the lower the level of shoulder disability
Shoulder examination for the difference in Passive Range of Motion2 weeks, 3 months, 6 months, 1 year, 2 years after surgeryExamining passive range of motion - forward flexion, external rotation, abduction
Shoulder examination for the difference in Active Range of Motion3 months, 6 months, 1 year, 2 years after surgeryExamining active range of motion - internal rotation up posterior thorax. Strength- Jobes, external rotation, lift-off and belly-press
