Summary
Arthroscopic shoulder stabilization for recurrent anterior instability may have higher failure rates than open methods. Decision analysis helps choose the best technique based on patient values, procedure risks, and surgeon success rates.
Area of Science:
- Orthopedic Surgery
- Decision Analysis
- Biostatistics
Background:
- Recurrent anterior instability of the glenohumeral joint often requires surgical stabilization.
- Arthroscopic techniques are increasingly used but may have higher midterm failure rates compared to open methods.
Purpose of the Study:
- To evaluate midterm failure rates of arthroscopic versus open shoulder stabilization.
- To introduce expected value decision analysis as a tool for selecting optimal surgical techniques.
Main Methods:
- Review of midterm failure rates for arthroscopic and open shoulder stabilization procedures.
- Application of expected value decision analysis to compare surgical techniques.
Main Results:
- Arthroscopic shoulder stabilization may be associated with a higher risk of failure than open methods.
- Decision analysis highlights patient-specific factors influencing technique choice.
Conclusions:
- The choice between arthroscopic and open shoulder stabilization depends on patient-valued outcomes, procedural morbidity, and surgeon's success probabilities.
- Expected value decision analysis provides a structured framework for personalized surgical decision-making in shoulder instability.
