The anterior cruciate ligament, superficial medial collateral ligament, and posterior cruciate ligament (PCL) and the following individual structures of the posterolateral corner were evaluated for high\u2010grade injury: fibular collateral ligament, popliteus tendon, and popliteofibular ligament.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Out of 331 consecutive acute knee injuries with a hemarthrosis, 265 ligament injuries occurred in 187 patients (56%). Of these 187 patients with ligament injuries, 126 had isolated ligament injuries and 61 (33%) had combined multiple ligament injuries. Of the 187 patients with knee ligament injuries, 83 (44%) had isolated anterior cruciate ligament tears, 28 (15%) had isolated superficial medial collateral ligament tears, 11 (5%) had isolated PCL tears, and 4 (2.1%) had isolated posterolateral knee tears. Of the patients with posterolateral knee structure injuries, 87% (26\/30) had multiple ligament injuries, with the overall incidence of posterolateral knee injuries among all knee ligament injuries being 16% and among all acute knee injuries with a hemarthrosis being 9.1%. Of the 27 patients with PCL tears, 16 (52%) had combined multiple ligament injuries.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This study shows that in this population, the incidence of posterolateral knee injuries in patients with acute knee ligament injuries with a hemarthrosis was 9.1%.
