Meniscal Injuries Associated With Acute Anterior Cruciate Ligament Tears in Alpine Skiers

Abstract

We reviewed the records of 315 patients receiving an arthroscopically assisted stabilizing procedure for an acute anterior cruciate ligament injury incurred while alpine skiing to evaluate associated meniscal inju ries. Meniscal injuries were classified by type, loca tion, and treatment of the tear. Of the 317 knees op erated on, all demonstrated an anterior cruciate ligament tear at arthroscopy. Ninety-eight percent of the injuries (310) were diagnosed within 3 days of injury, and 97% (307) were reconstructed within 28 days of injury. All tears occurred in the intrasubstance of the ligament; 32% were isolated injuries and 68% were combined with other injuries. In 159 patients with 170 meniscal tears 141 of the tears (83%) were lateral and 29 (17%) were medial. The injury triad of anterior cruciate ligament-medial collateral ligament- lateral meniscus was seen nine times as often as the anterior cruciate ligament-medial collateral ligament- medial meniscus combination.
