Outline of Final Research Achievements |
We investigated the relationship between kinematics / kinetics and patient satisfaction level, Forgotten Joint Score (FJS)-12, in hip joint disease. The study included 164 patients with unilateral hip disease. The first study investigated the relationship between leg-length discrepancy as kinematics and FJS-12. FJS-12 at 1 year after THA was poor in patients with a subject feeling of leg lengthening even if the radiological leg length difference was less than 5mm poor. The second study investigated the relationship between physical activity level as kinetics and FJS-12. A significant correlation was found between preoperative activity level and FJS-12 at 1 year postoperatively. The number of steps was improved to the preoperative level at 2 to 3 months postoperatively, and the activity level was improved to the preoperative level at 3 to 6 months postoperatively.

Academic Significance and Societal Importance of the Research Achievements |
Forgotten Joint Score (FJS)-12と人工股関節全置換術(THA)後の脚長差や活動量との関係に関する報告はこれまでにない。 キネマティクスとしての脚長差に関して、THA後の自覚的脚長差について術側が長く感じる場合は有意にFJS-12が不良で、画像的脚長差が5mm未満であっても同様であることが明らかとなった。THA後の脚長差は5mm未満とすることが重要であることが示唆された。 キネティクスとしての活動量に関して、術前活動量レベルと術後1年時のFJS-12に有意な相関がみられ、各患者の術前の活動量から、術後1年の活動量および満足度予測が可能となりうることが示唆された。
