Summary

Researchers are comparing two common types of total shoulder replacement, anatomic and reverse, in adults who already had the surgery. The study tracks patient-reported pain and function scores, complications, and revision surgeries for three years. They also check how often the implant used during surgery differed from the preoperative 3D surgical plan, and whether those differences relate to outcomes. Participants' existing medical records are reviewed, and some may complete a one-time questionnaire by phone or online.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If one implant design clearly outperforms the other for certain shoulders, surgeons could match patients to the replacement type most likely to restore pain-free function.
What could go wrong
This observational study follows people who already had surgery, so it can show links but not prove one implant causes better results. Findings may not apply to everyone, and some participants may be lost to follow-up.
