Different kinds of tendons were used to simulate a tendon graft or pulley reconstruction, and excursion resistance between tendon and pulley were evaluated.Intrasynovial tendons, (i.e., flexor digitorum superficialis and the portion of the extensor indicis proprius beneath the extensor retinaculum) produced less excursion resistance than extrasynovial tendons, (i.e., the portion of the extensor digitolum communis distal to the extensor retinaculum and palmaris longus). The excursion resistance of the intrasynovial portion of the extensor digitolum communis tendon was significantly higher than that of the extrasynovial portion of the same tendon.The gliding resistances of tendons were significantly decreased after administration of HA, especially in the extrasynovial tendons. Excursion resistances of the extrasynovial tendons after administration of HA were not significantly different from the control values. The results of this study suggest that the administration of HA may possibly to improve the clinical outcome of the flexor tendon graft.

使用不同种类的肌腱来模拟肌腱移植物或滑轮重建，并评估肌腱和滑轮之间的偏移阻力。指浅屈肌和伸肌支持带下方的食指固有伸肌部分）产生比滑膜外肌腱更小的偏移阻力，（即，趾总伸肌的远离伸肌支持带和掌长肌的部分）。趾总伸肌腱滑膜内部分的滑动阻力显著高于滑膜外部分，HA可显著降低肌腱的滑动阻力，尤其是滑膜外肌腱。注射HA后滑膜外肌腱的偏移阻力与对照值无显著差异。本研究结果提示，HA的应用可能改善屈肌腱移植的临床效果。
