a Relationship between IL-8 and VEGF in remnant-preserved ACLR. We selected two patients who underwent remnant-preserved ACLR: IL-8 concentration (top panels) and VEGF concentration (bottom panels). Data expressed as median value; *p < 0.05, **p > 0.05 compared to 3 months postoperatively by Student’s t test. Data are representative of experiments that were repeated three times. b Relationship between IL-8 and VEGF in conventional ACLR. We selected two patients who underwent conventional ACLR. IL-8 concentration on a trimonthly basis (top panels) and VEGF concentration on a trimonthly basis (bottom panels). Data were expressed as median value; *p < 0.05 compared to 3 months postoperatively by Student’s t test. Data are representative of experiments that were repeated three times.
