The average duration of follow-up was 4.3 years. The fifty-four patients who were available for follow-up had an average total Cincinnati score of 65.7 points. A significant improvement was found between the preoperative and postoperative IKDC objective scores for varus opening at 20\u00b0, external rotation at 30\u00b0, reverse pivot shift, and single-leg hop.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS:<\/jats:title>\n                    <jats:p>An anatomic posterolateral reconstruction resulted in improved clinical outcomes and objective stability for patients with a grade-3 posterolateral knee injury.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LEVEL OF EVIDENCE:<\/jats:title>\n                    <jats:p>\n                      Therapeutic\n                      <jats:underline>Level IV<\/jats:underline>\n                      .
