Abstract

The study aimed to describe the changes in biomechanical properties of the supraspinatus tendon, deltoid muscle, and humeral head post arthroscopic rotator cuff repair using shear wave elastography. Shear wave velocity of the tendon, deltoid, and humeral head of 48 patients was measured at predetermined sites at 1 week, 6 weeks, 12 weeks, 6 months, and 12 months post repair. One-way ANOVA with Tukey's correction and Spearman's correlation were performed. Mean±SEM healing tendon stiffness, adjacent to tendon footprint, increased from 1 week (6.2±0.2 m/s) to 6 months (7.5±0.3 m/s) and 12 months (7.8±0.3 m/s) (P<0.001). Mean±SEM deltoid muscle stiffness was higher at 12 months (4.1±0.2 m/s) compared to 1 week (3.4±0.1 m/s) and 12 weeks (3.5±0.1 m/s) (P<0.05). Humeral head stiffness did not change. Following arthroscopic rotator cuff repair, supraspinatus tendon stiffness increased in a curvilinear fashion over 6 months. From 6 months, deltoid muscle stiffness increased, corresponding to when patients were instructed to return to normal activities.

肩袖修复术后肩部的命运：冈上肌腱及其周围结构的生物力学特性。

该研究旨在利用剪切波弹性成像技术描述关节镜下肩袖修复术后冈上肌腱、三角肌和肱骨头生物力学特性的变化。在修复后 1 周、6 周、12 周、6 个月和 12 个月时，在预定部位测量 48 名患者肌腱、三角肌和肱骨头的剪切波速度。进行了单因素方差分析和 Tukey 校正以及 Spearman 相关性分析。邻近肌腱足迹的愈合肌腱僵硬度平均值（±SEM）从 1 周（6.2±0.2 m/s）增加到 6 个月（7.5±0.3 m/s）和 12 个月（7.8±0.3 m/s）（P<0.001）。与 1 周（3.4±0.1 m/s）和 12 周（3.5±0.1 m/s）相比，12 个月时（4.1±0.2 m/s）三角肌僵硬度的平均值（±SEM）更高（P<0.05）。肱骨头硬度没有变化。关节镜下肩袖修复术后，冈上肌腱硬度在6个月内呈曲线上升。6个月后，三角肌僵硬度增加，这与患者被要求恢复正常活动的时间一致。

期刊介绍： Sports Medicine and Arthroscopy Review helps physicians digest the large volume of clinical literature in sports medicine and arthroscopy, identify the most important new developments, and apply new information effectively in clinical practice. Each issue is guest-edited by an acknowledged expert and focuses on a single topic or controversy. The Guest Editor invites the leading specialists on the topic to write review articles that highlight the most important advances. This unique format makes the journal more in-depth, authoritative, and practical than most publications in this field. The journal also includes dozens of full-color and black-and-white arthroscopic images and illustrations.
