Corticosteroid injection versus platelet-rich plasma in the management of knee osteoarthritis: A comparative clinical study
Bibliographic record
Abstract
Background: Knee osteoarthritis (OA) is a prevalent degenerative joint disorder causing pain and disability. Intra-articular corticosteroid (CS) injections provide short-term relief, while plateletrich plasma (PRP) has emerged as a regenerative option with potentially longer benefits. Objective: To compare the efficacy of intra-articular corticosteroid versus PRP injections in patients with symptomatic knee osteoarthritis. Methods: A prospective randomized comparative study was conducted on 60 patients with Kellgren-Lawrence grade II-III knee OA. Group A (n = 30) received a single intra-articular corticosteroid injection (triamcinolone acetonide 40 mg). Group B (n = 30) received three PRP injections at weekly intervals. Outcomes were assessed using the Visual Analogue Scale (VAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at baseline, 6 weeks, 3 months, and 6 months. Results: Both groups showed significant pain reduction at 6 weeks. Group A improved from 7.2± 1.0 to 3.1±1.2, while Group B improved from 7.4±1.1 to 3.4±1.0 (p > 0.05). At 3 and 6 months, PRP maintained superior improvement (VAS 2.1±0.9; WOMAC 34.2±6.5) compared to corticosteroid (VAS 4.5±1.2; WOMAC 51.7±8.3) (p

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
