大腿四頭筋腱同種移植片を用いた前十字靭帯再建術（骨ブロックあり・なし）

Of the grafts available for anterior cruciate ligament (ACL) reconstruction, the quadriceps tendon (QT) autograft has seen increased attention in recent years. However, the use of quadriceps allograft has lagged behind. Quadriceps allograft has several advantages similar to those which have driven the use of quadriceps autograft, such as biomechanical properties, histological similarity to the native ACL, and increased cross-sectional area. This article presents the use of QT allograft with bone block and without bone block. Surgical techniques, fixation methods, and clinical indications of each graft are discussed, as well as the advantages of each technique.
