Application of Machine Learning Algorithms for Prognostic Assessment in Rotator Cuff Pathologies: A Clinical...

Area of Science:

• Orthopedic Surgery
• Machine Learning in Medicine
• Biomedical Data Science

Background:

• Rotator cuff (RC) tears are a common cause of shoulder disability.
• Accurate prediction of surgical outcomes is crucial for patient care and management.
• Machine learning (ML) offers potential for improving prognostic accuracy in orthopedic surgery.

Purpose of the Study:

• To apply machine learning algorithms for predicting patient outcomes after arthroscopic rotator cuff repair.
• To identify key predictive factors influencing the success of rotator cuff repair surgery.
• To evaluate the performance of various ML models in outcome prediction.

Main Methods:

• 100 patients undergoing arthroscopic rotator cuff repair were evaluated.
• Predictive factors included demographics, patient-reported outcome measures, and clinical scores.
• State-of-the-art ML algorithms (SVM, k-NN, NB, RF, LR) were employed for analysis.

Main Results:

• Machine learning classifiers demonstrated suboptimal performance in predicting outcomes.
• Logistic Regression (LR) achieved a mean accuracy of 46.5% ± 6%, and Random Forest (RF) achieved 51.25% ± 4%.
• No significant differences were observed in the performance metrics across different ML algorithms.

Conclusions:

• Current ML approaches using available clinical and demographic data have limitations in predicting rotator cuff repair outcomes.
• Data quality and the inclusion of specific variables (e.g., smoking, diabetes) may impact predictive accuracy.
• Future research should explore novel predictors like neuroimaging and kinematic data to enhance AI-driven prognostic models for RC patients.
