Each patient received four intra-articular PRP injections per knee (7\u20138 ml; 2\u20133 \u00d7 concentration) at 4\u20135-week intervals. PRP was prepared using MARSPILL criteria: Non-activated, leukocyte-rich, double-spin, in a closed system, and administered within 60 min of preparation. The PRP preparation process was supervised by the transfusion medicine department. Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores were recorded at baseline and at 3, 6, and 12 months posttreatment, along with monitoring for adverse events.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      Mean WOMAC total scores improved significantly from 58.28 \u00b1 7.7 at baseline to 27.48 \u00b1 9.9, 26.31 \u00b1 6.9, and 29.59 \u00b1 7.3 at 3, 6, and 12 months, respectively (all\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.001).
