To compare the efficacy of intraarticular knee injection between leukocyte-rich and leukocyte-poor platelet-rich plasma in knee osteoarthritis treatment
Participants were randomized into 3 groups (leukocyte-rich platelet-rich plasma (LR-PRP), leukocyte-poor platelet-rich plasma (LP-PRP), and Corticosteroid (CS)). The primary outcome of this study is The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and was measured pre-treatment and post-treatment at follow-up at 1, 3, and 6 months

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Leukocyte-rich platelet-rich plasma | Experimental | Leukocyte-rich PRP: Centrifuge at 300 G for 5 min, separate the plasma and buffy coat layers, and then centrifuge at 700 G for 17 min with calcium chloride at the ratio of 1:5 to PRP by volume. |
|
| Leukocyte-poor platelet-rich plasma | Experimental | Leukocyte-poor PRP: Centrifuge at 123 G for 15 min, separate the plasma and buffy coat layers, and then centrifuge at 448 G for 10 min. Calcium chloride was added 1:5 to PRP by volume. |
|
| Corticosteroid | Experimental | Corticosteroid: 1 ml of triamcinolone acetonide (40mg/ml) mixed with 0.9% NaCl to a total volume of 4 ml. |
