外傷性多重靭帯膝関節損傷および膝蓋腱断裂の管理：症例報告

Although ligamentous injuries to the knee are a common occurrence, concomitant rupture of the patellar tendon (PT) is a rare finding. We present the case of a 28-year-old male who sustained a multiligamentous injury of the knee, which involved the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), and medial collateral ligament (MCL) along with a rupture of the PT secondary to a dirt bike accident. We also review the current treatment guidelines for multiligamentous knee injuries based on the available literature. This unique presentation was treated surgically using a two-staged approach: an initial acute repair of the PT and MCL, followed by an arthroscopic reconstruction of the ACL and PCL using allograft tissues. This approach, combined with an aggressive rehabilitation program, can lead to a satisfactory clinical outcome for a multiligamentous knee injury in combination with a rupture of the PT.
