剪切波弹性成像评估腓骨长肌腱自体移植物用于ACL重建后供区并发症
简介
该研究采用剪切波弹性成像评估ACL重建中腓骨长肌腱自体移植物取材后的供区病损。40例患者术后12个月时，取材侧与对侧在踝关节跖屈、外翻活动度及肌腱硬度上均无显著差异，且术后疼痛评分较术前显著改善。提示腓骨长肌腱取材在1年随访期内未造成可测量的供区功能障碍，可作为ACL重建的备选移植物。
英文摘要
Background/Objectives: The peroneus longus tendon has gained attention as an alternative autograft source for anterior cruciate ligament reconstruction; however, donor-site morbidity remains a concern because of its role in ankle eversion and lateral ankle function. Methods: This cross-sectional observational study evaluated whether peroneus longus tendon harvest causes measurable donor-site changes using shear wave elastography. Forty patients who underwent anterior cruciate ligament reconstruction with a peroneus longus tendon autograft and who completed at least 12 months of follow-up were included. The graft-harvested side was compared with the contralateral side in terms of ankle plantar flexion, eversion range of motion, and shear wave elastography-derived tendon stiffness. Results: Pain was assessed using the visual analog scale. Postoperative VAS scores were significantly lower than preoperative scores [8 (5-9) vs. 2 (1-4); p < 0.001]. No significant differences were found between the graft-harvested and contralateral sides in plantar flexion, eversion, or tendon stiffness. A strong positive correlation was observed between operated-side and contralateral-side shear wave elastography values (r = 0.950; p < 0.001). Conclusions: Peroneus longus tendon harvest was not associated with measurable residual tendon stiffness or ankle range-of-motion changes at 12 months.
