Predicting Patient Satisfaction With Maximal Outcome Improvement After Biceps Tenodesis

Area of Science:

• Orthopedic Surgery
• Patient Outcomes Research

Background:

• Biceps tenodesis is a common procedure for shoulder pain.
• Predicting patient satisfaction after surgery is crucial for evaluating success.
• Establishing clear outcome improvement thresholds can standardize success metrics.

Purpose of the Study:

• To determine the maximal outcome improvement (MOI) thresholds on the American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation (SANE), and Constant-Murley (CM) questionnaires that predict patient satisfaction.
• To identify predictors of achieving these MOI thresholds after isolated biceps tenodesis.

Main Methods:

• Retrospective analysis of prospectively collected data from 123 patients undergoing isolated biceps tenodesis.
• Receiver operating characteristic (ROC) curve analysis to establish MOI thresholds for satisfaction.
• Stepwise multivariate logistical regression to identify predictors for achieving MOI thresholds.

Main Results:

• The MOI thresholds for satisfaction were determined as 43.1% for ASES, 62.1% for SANE, and 61.4% for CM questionnaires.
• Concomitant superior labrum anterior-posterior (SLAP) repair predicted higher MOI on ASES and SANE.
• Partial rotator cuff tear predicted higher MOI on CM.
• Workers' compensation status, diabetes, prior ipsilateral shoulder surgery, and hypertension were negative predictors for achieving MOI on SANE and CM.

Conclusions:

• Specific MOI percentages on the ASES, SANE, and CM questionnaires serve as reliable predictors of patient satisfaction following biceps tenodesis.
• Concomitant SLAP repair is associated with improved outcomes.
• Certain patient factors, including health conditions and compensation status, negatively impact surgical outcomes.
