This study is looking at shoulder replacements, called shoulder arthroplasty. It observes both anatomic (traditional) and reverse (for different shoulder issues) types of replacements. The study involves patients who are either planning to get or have already received a shoulder replacement using the Shoulder Innovations (SI) Total Shoulder System. The goal is to see how patients do over a long time, up to 10 years after their surgery.
- Participants need to be at least 18 years old and agree to follow-up visits.
- Some activities are involved, like answering questions about how you feel after surgery.
- You should not join if you're in another conflicting study or unable to follow the study rules.
