Other perioperative interventions were identical for all patients. The primary outcome was the postoperative pain score 24\u00a0hours after surgery, which was measured using a 100\u2010mm visual analog scale (VAS). The pain scores were also assessed to determine whether the VAS score would reach the threshold values reported for the minimal clinically important difference (MCID) and patient acceptable symptomatic state (PASS).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The PI group had significantly lower VAS scores 24\u00a0hours after ACL reconstruction than the FNB group (21\u00a0mm vs 39\u00a0mm;\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .0001). Consequently, the primary outcome reached the level of clinical significance as indicated by the threshold values of an MCID of 9.9 and a PASS of 33. The PI group also had a significantly lower VAS score at rest at 4\u00a0hours, 8\u00a0hours, and 2\u00a0days after surgery (30\u00a0mm vs 39\u00a0mm [\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .025], 25\u00a0mm vs 33\u00a0mm [\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .022], and 22\u00a0mm vs 32\u00a0mm [\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .0022], respectively).
