To compare the one year outcomes between 60 year old patients with a three tendon tear treated as part of their standard of care with either a reverse total shoulder arthroplasty or rotator cuff repair surgery.

A retrospective record review will be completed to identify eligible subjects who had either a reverse total shoulder arthroplasty or rotator cuff repair to treat their three tendon tear. Medical record abstraction of standard of care will be completed among the reverse total shoulder arthroplasty cohort. Rotator cuff repair subjects will be contacted with a study invitation and scheduled for a single study visit to collect three patient reported outcomes, assess range of motion and complete a ten-minute magnetic resonance imaging exam following signed consent.

Inclusion Criteria:

• 60 years of age or more at time of surgery
• One year post-reverse total shoulder arthroplasty or one year post-rotator cuff repair involving all three tendons (infraspinatus, supraspinatus, subscapularis)
• Surgery completed by Dr. Tyler Brolin or Dr. Thomas Throckmorton

Exclusion Criteria:

• Less than 60 years of age at time of surgery
• Less than one year post-reverse total shoulder arthroplasty or post-rotator cuff repair
• Procedure completed by another provider than Dr. Brolin or Dr. Throckmorton
• Worker's compensation
• Fewer than three tendon tear

Eligible subjects will be patients of either Dr. Brolin or Dr. Throckmorton who had either a reverse total shoulder arthroplasty or rotator cuff repair for treatment of a three tendon tear and are 60 years of age and older.

Individual Participant Data will not be shared.
