Abstract:
Two patients suffered similar knee injuries due to valgus stress and hyperextension. Examination under anesthesia and arthroscopic evaluation revealed a previously unreported ligament injury pattern. Both patients had a complete tear of the anterior cruciate ligament and a partial tear of the posterior cruciate ligament; neither was noted to have a dislocation. The descriptive term identifying this injury pattern is "incomplete bicruciate knee injury." The purpose of this report is to identify this knee-injury complex, which appears to be part of the sequence that leads to complete tears of both cruciate ligaments--the classic knee dislocation.
