Outline of Research at the Start

前十字靭帯(ACL)損傷は代表的な膝外傷の一つであり、二次性の変形性関節症の原因となる。ACL損傷に対する主な治療法は靱帯再建術である。しかし、靱帯再建術だけでは変形性関節症の発症を完全に予防することはできない。そのため、変形性関節症の発症を予防するもしくは遅延させる術後のリハビリテーションプロトコルの確立は重要な課題である。本研究では、ACL再建術後早期の荷重量の違いが変形性関節症の発症や進行に及ぼす影響を調べることで、変形性関節症予防に効果的なリハビリテーションプロトコルの確立に貢献する。

Outline of Final Research Achievements

This study aimed to determine the effect of the amount of weight bearing on articular cartilage degeneration after anterior cruciate ligament reconstruction using a rat model.
After anterior cruciate ligament reconstruction, increase in weight bearing via pain relief by morphine administration had no effect on cartilage degeneration. On the other hand, cartilage degeneration was exacerbated by non-weight bearing after anterior cruciate ligament reconstruction. The cartilage degeneration induced by non-weight bearing did not improve after reloading. Our results suggest that early weight bearing after anterior cruciate ligament reconstruction is important to reduce cartilage degeneration.

Academic Significance and Societal Importance of the Research Achievements

前十字靭帯再建後のリハビリテーションにおける適切な荷重量について、コンセンサスは得られていない。本研究では、前十字靭帯再建後の荷重量の違いが関節軟骨の変性に及ぼす影響を明らかにした。本研究の結果は、より良い前十字靭帯再建後のリハビリテーションプロトコル確立につながる重要な基礎データとなるであろう。
