What Does the Research Say?
Anatomic vs Reverse Shoulder Replacement: How Surgeons Choose
Both procedures reliably reduce pain. But one gives patients a significantly better shot at feeling "normal" again. Here's what drives the decision.
Anatomic Arthroplasty
Preserves Native Anatomy
Replaces the ball and socket while keeping the rotator cuff in charge of stability. Best for patients with an intact cuff and strong bone stock.
47%
achieve a "new normal" shoulder
Reverse Arthroplasty
Recruits the Deltoid Instead
Flips the ball-and-socket design so the deltoid muscle can compensate when the rotator cuff is gone. Originally for massive cuff tears, now expanding to older adults.
24%
achieve a "new normal" shoulder
External Rotation Advantage
15-25°
More rotation with anatomic
Anatomic arthroplasty consistently outperforms reverse in restoring rotational motion
Revision Rate (Reverse)
2-3%
At 5-year follow-up
Lower than anatomic (5-7%), reflecting the biomechanical simplicity of the reverse design
Age Threshold
≥75
When reverse may be preferred
Even with an intact cuff, older adults see comparable function and lower revision rates with reverse
Registry Evidence
20,000+
Arthroplasties analyzed
2024 National Joint Registry of England study confirming reverse superiority in elderly patients
3 Takeaways for Your Practice
1
Patient Counseling
Rotational Motion Is the Key Trade-Off
Anatomic arthroplasty preserves 15 to 25 degrees more external rotation than reverse. For younger patients who golf, swim, or do overhead work, that difference directly affects return to activity. Make sure patients understand what each option means for their daily life.
2
Rehab Planning
The Procedure Dictates Your Protocol
Anatomic arthroplasty requires strict subscapularis protection for 4 to 6 weeks, with no active elevation during Phase 1. Reverse arthroplasty allows immediate active motion in most cases. Knowing which procedure your patient had is the first step in designing safe, effective rehab.
3
Clinical Awareness
Reverse Indications Are Expanding Fast
Reverse arthroplasty is no longer just for massive cuff tears. Evidence now supports it for elderly patients with intact cuffs, complex fractures, and failed prior arthroplasty. Expect to see more reverse cases in your clinic, and know the different rehab implications.
