Background: Preoperative assessment of fatty degeneration is important for managing rotator cuff tears. The Goutallier classification semiquantitative and observer dependent. Discrepancies among surgeons can be prominent. A quantitative method may improve accuracy reliability in evaluating the exact percentage infiltration (Fat%). Hypothesis/Purpose: This study aimed to investigate correlation between new assessing (FI) supraspinatus muscle explore use this predicting retear after repair. It was hypothesized that would significantly correlate with more sensitive retear. Study Design: Cohort (diagnosis); Level evidence; 3. Methods: included 105 patients who underwent arthroscopic repair large massive All routine preoperative 1-year postoperative magnetic resonance imaging were divided into 2 groups according tendon healing. Fat% evaluated based on signal intensity (SI) T1-weighted sequence. calculated using following equation: SI = fat × + (1 – Fat%). grade determined. Univariate multivariate analyses performed identify independent risk factors Results: mean 23.77 ± 15.96. significant found ( R 0.655; P < .001). overall rate 21.9%; however, functional status improved regardless Multivariate analysis identified .005) modified Patte .003) as receiver operating characteristic curves showed cutoff value 33.2%. >33.2% possessed superior diagnostic (79.0%), Youden index (0.513), positive negative predictive values (51.6% 90.5%, respectively) compared grades. Conclusion: Although correlated classification, clinically relevant higher than grades
