Accuracy of the rotator cuff reparability score

Area of Science:

• Orthopedic Surgery
• Musculoskeletal Research

Background:

• Pre-operative determination of rotator cuff tear reparability is challenging.
• Identified risk factors for rotator cuff repair failure include age ≥ 65, acromiohumeral interval ≤ 6 mm, and anteroposterior tear size ≥ 22 mm.
• A rotator cuff reparability score was developed assigning one point per risk factor.

Purpose of the Study:

• To evaluate the diagnostic accuracy of the developed rotator cuff reparability score.
• To determine the optimal cut-off score for predicting rotator cuff repair success.

Main Methods:

• Retrospective cohort study of 80 patients with large or massive rotator cuff tears undergoing arthroscopic repair.
• Rotator cuff reparability scores were calculated for each patient.
• Statistical analysis included sensitivity, specificity, and ROC curve analysis to find the optimal cut-off score.

Main Results:

• The rotator cuff reparability score demonstrated good to excellent intra- and inter-observer reliability.
• An optimal cut-off score of two points yielded a sensitivity of 85.71% and specificity of 83.33%.
• The area under the ROC curve was 0.894, indicating high accuracy.

Conclusions:

• A rotator cuff reparability score of two is the optimal threshold for predicting the reparability of large or massive rotator cuff tears.
• This score can aid surgeons in pre-operative assessment and surgical planning for rotator cuff repair.
