　前十字靱帯(anterior cruciate ligament：ACL)損傷膝では関節内にさまざまな形態で遺残靱帯が存在する．この遺残ACLが膝関節の安定性に及ぼす生体力学的機能は不明な点が多い．本稿では，ナビゲーションシステムを用いて遺残ACLが膝関節安定性に与える影響を検討した．ACL再建手術を行った83名を対象に，遺残ACLの切除前後で脛骨前方移動量および回旋角度をナビゲーションシステムで計測した結果，遺残ACLは膝関節安定性に対して十分な生体力学的機能を認めなかった．したがって遺残ACLは，生体力学的機能ではなく，移植腱の成熟や関節固有感覚の改善を期待して温存を考慮すべきである．
