Outline of Final Research Achievements

Fear of re-injury is the most important factor inhibiting return to sport for patients after anterior cruciate ligament (ACL) reconstruction. In this study, we analyzed the relationship between fear of re-injury and kinematic and kinetic variables during the jump landing in 11 patients after ACL reconstruction. The level of the participating competitions was also taken into account in the analysis. The results showed that there was a significant correlation between the fear of re-injury and the knee joint flexion angle during jump landings. Based on the results of this study, we created a teaching program to support the return to sports and disseminated it in actual teaching fields.

Academic Significance and Societal Importance of the Research Achievements

ACLを損傷した患者の多くは受傷前と同じ競技レベルでのスポーツ復帰を目的に再建術を受ける。しかしこれを達成できる割合は約60%程度と高くなく、リハビリテーションおよびスポーツ医学分野における重大な課題となっている。再損傷恐怖感はスポーツ復帰を阻害する主要因であるが、その関連因子は不明である。再損傷恐怖感の関連因子を明らかにすることで、ACL再建術後のスポーツ復帰をサポートするための重要な根拠が得られると考えている。
