The investigators purpose of this study are to perform a prospective clinical study to determine the following after subscapularis-sparing anatomic total shoulder arthroplasty performed for glenohumeral osteoarthritis: 1. patient-reported outcomes 2. shoulder motion and strength 3. rotator cuff integrity 4. the accuracy of component placement and the completeness of osteophyte removal
Anatomic total shoulder arthroplasty (TSA) provides excellent pain relief and restoration of shoulder function in the setting of glenohumeral osteoarthritis. However, the surgical approach requires the subscapularis to be cut and repaired, via either a lesser tuberosity osteotomy, a subscapularis tenotomy, or a subscapularis peel.This repair must be protected post-operatively, even with a lesser tuberosity osteotomy, or it can displace or fail to heal, which complicates rehabilitation. Failure of the subscapularis repair occurs in 10-25% of patients. Failure of the subscapularis repair is ofte…
Inclusion Criteria: * Patients undergoing subscapularis-sparing anatomic total shoulder arthroplasty by the principal investigator at the University of Utah. Exclusion Criteria: * Patients unwilling to consent and comply with study procedures (i.e. follow up visits). * Patients under the age of 18. * Patients with contraindications to an anatomic total shoulder arthroplasty such as active infection, insufficient glenoid bone, damage to the rotator cuff, or a history of instability. * Patients with known prior shoulder arthroplasty. * Patients unable to undergo a magnetic resonance imaging s…
