摘要

目的:我们旨在研究非接触式腿筋损伤后接受手术修复的老年人在不同行走条件下的功能结果。方法:12 名患者(平均值 ± SD,年龄:65 ± 9 岁;体重指数:30 ± 6 kg/m2)在地面(0% 坡度)和跑步机(0% 和 10% 坡度)条件下以自选速度行走。我们测量了髋关节、膝关节和踝关节的时空参数、关节角度(按步态周期归一化)和关节力矩(按站立阶段归一化)。采用配对样本 t 检验(p 0.05)和轨迹配对差异的连续 95% 置信区间对两侧数据进行比较:结果:患者在地面行走的平均速度为 1.31 ± 0.26 米/秒,在跑步机上行走的平均速度为 0.92 ± 0.31 米/秒。受伤腿和对侧腿的时空参数相当(P > 0.05)。在所有行走条件下,两侧的关节运动学和关节运动学轨迹均具有可比性:结论:腘绳肌腱近端复位术使受伤腿和对侧腿术后至少 1 年的行走力学具有可比性,均在文献报道的正常值范围内。这些结果补充了我们之前关于腘绳肌腱修复在临床效果和肌肉力量方面的发现,并支持手术修复在老年人群的行走方面取得良好的功能效果。试验注册:clinicaltrials.gov (NCT04867746)。

Reconstruction of proximal hamstring ruptures restores joint biomechanics during various walking conditions.

Purpose: We aimed to examine the functional outcome in different walking conditions in elderly adults who underwent surgical repair after a non-contact hamstring injury. Our objective was to compare lower limb kinematics and kinetics over the entire gait cycle between the injured and contralateral leg in overground and level and uphill treadmill walking.

Methods: 12 patients (mean ± SD, age: 65 ± 9 years; body mass index: 30 ± 6 kg/m2) walked at self-selected speed in overground (0% slope) and treadmill conditions (0% and 10% slope). We measured spatiotemporal parameters, joint angles (normalised to gait cycle) and joint moments (normalised to stance phase) of the hip, knee and ankle. Data between sides were compared using paired sample t-tests (p< 0.05) and continuous 95% confidence intervals of the paired difference between trajectories.

Results: Patients walked at an average speed of 1.31 ± 0.26 m/second overground and 0.92 ± 0.31 m/second on the treadmill. Spatiotemporal parameters were comparable between the injured and contralateral leg (p> 0.05). Joint kinematic and joint kinetic trajectories were comparable between sides for all walking conditions.

Conclusions: Refixation of the proximal hamstring tendons resulted in comparable ambulatory mechanics at least 1 year after surgery in the injured leg and the contralateral leg, which were all within the range of normative values reported in the literature. These results complement our previous findings on hamstring repair in terms of clinical outcomes and muscle strength and support that surgical repair achieves good functional outcomes in terms of ambulation in an elderly population.

期刊介绍: HIP International is the official journal of the European Hip Society. It is the only international, peer-reviewed, bi-monthly journal dedicated to diseases of the hip. HIP International considers contributions relating to hip surgery, traumatology of the hip, prosthetic surgery, biomechanics, and basic sciences relating to the hip. HIP International invites reviews from leading specialists with the aim of informing its readers of current evidence-based best practice. The journal also publishes supplements containing proceedings of symposia, special meetings or articles of special educational merit. HIP International is divided into six independent sections led by editors of the highest scientific merit. These sections are: • Biomaterials • Biomechanics • Conservative Hip Surgery • Paediatrics • Primary and Revision Hip Arthroplasty • Traumatology
