Evolution of clinical scores in patients with KL grades 1–2 between BMAC (n = 16) vs PRP groups (n = 10). Changes (%) in (A) VAS scores, (B) KOOS scores, and (C) WOMAC scores from baseline are represented as mean ± 95% CI. Mean % change differences between treatment groups across 1 year are provided as mean change from baseline (%) [95% CI; P-value]. A significant difference was recorded in the mean change from baseline (%) in all scores. A general linear model for repeated measures was used to calculate p-values between treatment groups. BMAC, bone marrow aspirate concentrate; CI, confidence interval; PRP, platelet-rich plasma
