Abstract
Background Orthobiologic treatments such as autologous platelet‐rich plasma (A‐PRP) and mesenchymal stem cells (MSCs) are widely used for knee osteoarthritis (OA). Umbilical cord–derived PRP (UCD‐PRP), with its standardized composition and high growth factor content, has emerged as a promising allogeneic alternative, though comparative data are limited. Purpose To compare the short‐term clinical outcomes of UCD‐PRP versus adipose tissue–derived MSCs (ADT‐MSCs) following debridement and lavage arthroscopy in patients with early‐stage knee OA. Study Design Cohort study; Level of evidence, 3. Methods This retrospective study included 225 patients with Kellgren–Lawrence grade I‐II knee OA treated with either UCD‐PRP ( n = 75) or ADT‐MSCs ( n = 150) after arthroscopy. Outcomes assessed at baseline, 6, and 12 months included the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Knee Injury and Osteoarthritis Outcome Score (KOOS), International Knee Documentation Committee (IKDC) score, and Visual Analog Scale (VAS) for pain. Multivariate analysis assessed predictors of outcome. Results Both groups showed significant functional and pain improvements from baseline at all follow‐up points. The UCD‐PRP group demonstrated superior pain reduction on VAS at 3 and 6 months compared with ADT‐MSCs (ΔVAS at 3 months, p = 0.042; at 6 months, p = 0.0065). Functional scores (WOMAC, KOOS, and IKDC) showed no significant between‐group differences at 12 months. Higher BMI was independently associated with poorer clinical outcomes ( p < 0.001). Conclusion UCD‐PRP provides superior short‐term pain relief compared with ADT‐MSCs following knee arthroscopy for early OA, with comparable functional outcomes at 12 months. Its standardized, allogeneic preparation and minimal donor‐site morbidity make UCD‐PRP a promising orthobiologic option for knee OA management. Level of Evidence Level III.

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 it
