　前十字靱帯(anterior cruciate ligament：ACL)再建術術後の再断裂は現状で不可避かつ深刻な術後合併症である．ACL再断裂に対する治療を初回受傷と同一に行っても再受傷を繰り返してしまうことが危惧され，再ACL再建術時には追加処置も検討される．近年，再認識されているのが関節外組織の補強術であり，中でも高度な臨床研究において再断裂率の減少を確認された手術法が外側関節外腱固定術(lateral extraarticular tenodesis：LET)である．ここでは関節外組織の補強術の歴史的背景と実際の手術法を紹介する．LETは適応を十分に検討すれば，臨床上有効なACL再再建時に用いることのできる追加治療と考えられる．
