Figure 4From: Prospective evaluation of serum biomarker levels and cartilage repair by autologous chondrocyte transplantation and subchondral drilling in a canine modelThe prospective values of serum WF6 (a) and hyaluronic acid (HA) (b) concentration (n = 10). Boxes represent medians and data distribution. The results show no statistically significant difference of serum WF6 or serum HA level at any time point. AC, autologous chondrocyte transplantation; SD, subchondral drilling.Back to article page
