  "abstract": "Partial-thickness rotator cuff tears are a frequent cause of persistent shoulder pain and restricted motion after failure of conservative treatment. Platelet-rich plasma (PRP) and injectable platelet-rich fibrin are autologous orthobiological treatments, but comparative evidence in partial-thickness tears is limited. This study compared pain, shoulder range of motion, and functional outcomes after PRP and injectable platelet-rich fibrin injection. This prospective study was conducted at a tertiary teaching hospital in Andhra Pradesh, from June 2023 to December 2024. Fifty adults with magnetic resonance imaging-documented partial-thickness rotator cuff tears and persistent symptoms despite 3 months of conservative treatment were randomized equally to PRP or injectable platelet-rich fibrin. Pain and shoulder outcomes were assessed at baseline, 3 weeks, 3 months, 6 months, and 1 year. At 1 year, injectable platelet-rich fibrin had lower visual analog scale scores than PRP (median 1.5 [IQR 1.0-2.5] vs. 2.5 [1.5-3.5]; P = 0.011). PRP had higher forward flexion (170° [160-180] vs. 140° [120-160]; P = 0.002), external rotation in neutral (70° [60-90] vs. 45° [40-60]; P = 0.001), external rotation at 90° abduction (70° [60-80] vs. 50° [40-60]; P = 0.002), and internal rotation at 90° abduction (60° [50-70] vs. 40° [30-50]; P = 0.002). PRP also showed higher American Shoulder and Elbow Surgeons and University of California, Los Angeles scores and lower Shoulder Pain and Disability Index and Quick Disabilities of the Arm, Shoulder and Hand scores at 1 year. Both PRP and injectable platelet-rich fibrin were associated with improvement in pain, function, and shoulder motion. In this cohort, PRP showed better long-term functional and range-of-motion outcomes, while injectable platelet-rich fibrin showed greater long-term pain reduction. The findings should be interpreted cautiously because of baseline differences in age and several shoulder motion measures and the modest sample size.",
