Effect of Leukocyte Concentration on the Efficacy of Platelet-Rich Plasma in the Treatment of Knee Osteoarthritis
This meta-analysis evaluated the impact of leukocyte concentration in platelet-rich plasma (PRP) on clinical outcomes for knee osteoarthritis (KOA). Analyzing six randomized controlled trials and three prospective studies encompassing 1,055 patients, the study compared leukocyte-poor PRP (LP-PRP) and leukocyte-rich PRP (LR-PRP) against hyaluronic acid (HA) and placebo. LP-PRP demonstrated significantly
