About this trial

The purpose of this double-blind randomized controlled trial is to compare patient-reported, clinical, and functional outcomes in patients undergoing RTSA with and without subscapularis repair after placement of a modern "lateralized" implant over the course of 24-months postoperative.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Clinical diagnosis of glenohumeral arthritis, rotator cuff arthropathy, or massive irreparable rotator cuff tear with surgeon-patient decision to undergo RTSA

First RTSA implantation

Absence of neoplastic diseases at the treated site

Fatty infiltration of the subscapularis is low-grade (i.e. Goutallier < Grade 3) based on pre-operative CT performed as standard of care in the patient group

Disqualifiers

Previous shoulder arthroplasty (hemi-, total shoulder, or RTSA)

Avascular necrosis

Post-infectious arthritis

Proximal humerus fracture

Trial outcomes

Primary outcomes

1

ASES Score

The ASES is a patient-reported upper extremity-specific functional assessment tool and is scored out of a maximum 100 points, where 100 represents maximum function and no pain (Richards et al., 1994). It has a pain component measured on a visual analog scale as well as ten Likert-scale questions on function (e.g., put on a coat, sleep on affected side). The ASES is reliable and is validated for this population and is one of the most commonly used shoulder outcomes in North America.

Time frame
24 months post-operative

Secondary outcomes

1

Constant Score

The Constant Score is validated and reliable PROM/clinical tool used to evaluate overall shoulder function based on pain, activities of daily living, and the clinical evaluation of ROM and strength (Constant \& Murley, 1987). This score is widely reported in European-based literature. Minimum value is 0 and maximum value is 100, with higher scores being a better outcome.
