What Does the Research Say?
Shoulder Replacement Rehab Guidelines: The Gap Between Evidence and Practice
Most publicly available rehabilitation protocols for anatomic shoulder arthroplasty do not align with the best available evidence. Here is what that means for your patients.
23%
of publicly available rehabilitation protocols for anatomic shoulder arthroplasty closely follow the ASSET consensus guidelines. The rest deviate in sling duration, motion limits, timing of active motion, or strengthening progression.
What Are the ASSET Guidelines?
The American Society of Shoulder and Elbow Therapists published a consensus statement in 2020 establishing evidence-based standards for anatomic arthroplasty rehabilitation. These guidelines represent the collective expertise of the leading shoulder specialists, distilled from the best available research.
ASSET Elevation Limit
120°
Phase 1 passive elevation in scapular plane
ASSET External Rotation Limit
30°
Phase 1 passive ER with arm at side
ASSET Sling Duration
4-6 wk
Continuous neutral rotation sling
Strengthening Start
12 wk
Progressive resistance begins Phase 3
Why Does This Matter?
When protocols deviate from evidence-based guidelines, patients face inconsistent care. Some may be progressed too aggressively, risking subscapularis failure. Others may be kept too conservative, increasing stiffness risk. Standardization improves outcomes across the board.
Comparison
What the Evidence Supports
Passive ROM on day 1 within strict limits
4-6 week sling
Active motion at 6 weeks
Strengthening at 12 weeks
No subscapularis-specific exercises needed beyond standard protocol
Comparison
Common Deviations Found
Variable sling durations (2-8 weeks)
Inconsistent ROM limits
Early active motion before 6 weeks
Premature strengthening
Added subscapularis-specific exercises without evidence of benefit
3 Takeaways for Your Practice
1
Guideline Adoption
Know the ASSET Guidelines and Use Them as Your Baseline
The 2020 consensus statement is the most rigorously developed framework available. Start there, then adjust based on surgeon communication and patient-specific factors. Do not rely on protocols you find online without verifying them against the evidence.
2
Surgeon Partnership
Ask the Surgeon What They Did, Not Just What They Want
Understanding the intraoperative findings, tissue quality, and specific repair technique helps you calibrate the protocol intelligently. A standard protocol without surgical context is guesswork.
3
Outcome Tracking
Measure What Matters at Every Phase Transition
Use the ASES score, range of motion benchmarks, and strength testing at 6 weeks, 3 months, 6 months, and 1 year. Quantitative benchmarks from 2025 research: abduction over 113 degrees, elevation over 162 degrees, external rotation over 52 degrees, and internal rotation to L1.
