Abstract

Background

It is conceivable that candidates for total knee arthroplasty due to knee osteoarthritis have poorer walking ability than people who do not have an indication for total knee arthroplasty. This study explored the discriminative ability of mobility metrics between individuals with and without an indication for total knee arthroplasty.

Methods

Mobility metrics were collected with inertial sensors on the same day as the consultation with the orthopedic surgeon in which the decision for total knee arthroplasty eligibility was made. Inertial sensors on both feet, lower back and trunk were used to collect gait data during short mobility tests. Participants walked along a 10-m walkway for two minutes, and performed sit-to-stand tasks. Based on the orthopedic surgeon's indication for total knee arthroplasty, individuals were assigned to the indication (N = 58) group or no indication (N = 73) group. Mobility metrics reflecting walking, turning and rising from a chair were compared between groups, and corrected for confounding variables.

Findings

Both groups had similar demographic and clinical characteristics, except for higher radiographic osteoarthritis severity in the indication group. Gait speed was 0.08 m/s (95 %CI: [−0.15, −0.01]) lower in the indication group compared to the no indication group. No significant differences were found in other mobility metrics.

Interpretation

Unlike expected, the difference in mobility metrics between individuals with and without a total knee arthroplasty indication was small. This finding implies that the ability to walk, turn and rise from a chair plays a minor role in the decision-making process regarding TKA.

有和没有膝关节置换术指征的个体的活动指标：一项探索性分析

背景：可以想象，由于膝关节骨性关节炎而进行全膝关节置换术的患者比没有全膝关节置换术指征的患者行走能力差。本研究探讨了有和没有全膝关节置换术指征的个体之间活动指标的判别能力。方法在与骨科医生会诊并决定是否进行全膝关节置换术的当天，用惯性传感器收集患者的移动指标。双脚、下背部和躯干上的惯性传感器用于在短时间移动测试中收集步态数据。参与者沿着一条10米长的人行道走两分钟，并完成坐到站的任务。根据骨科医生对全膝关节置换术的指征，将患者分为指征组（N = 58）和无指征组（N = 73）。反映行走、转身和从椅子上站起来的活动指标在两组之间进行了比较，并对混杂变量进行了校正。结果两组具有相似的人口统计学和临床特征，除了指征组骨关节炎的放射学严重程度更高。与无指征组相比，有指征组的步态速度低0.08 m/s （95% CI:[- 0.15, - 0.01]）。在其他活动指标上没有发现显著差异。与预期不同的是，有和没有全膝关节置换术指征的个体在活动指标上的差异很小。这一发现表明，走路、转身和从椅子上站起来的能力在TKA的决策过程中起着次要作用。

期刊介绍： Clinical Biomechanics is an international multidisciplinary journal of biomechanics with a focus on medical and clinical applications of new knowledge in the field. The science of biomechanics helps explain the causes of cell, tissue, organ and body system disorders, and supports clinicians in the diagnosis, prognosis and evaluation of treatment methods and technologies. Clinical Biomechanics aims to strengthen the links between laboratory and clinic by publishing cutting-edge biomechanics research which helps to explain the causes of injury and disease, and which provides evidence contributing to improved clinical management. A rigorous peer review system is employed and every attempt is made to process and publish top-quality papers promptly. Clinical Biomechanics explores all facets of body system, organ, tissue and cell biomechanics, with an emphasis on medical and clinical applications of the basic science aspects. The role of basic science is therefore recognized in a medical or clinical context. The readership of the journal closely reflects its multi-disciplinary contents, being a balance of scientists, engineers and clinicians. The contents are in the form of research papers, brief reports, review papers and correspondence, whilst special interest issues and supplements are published from time to time. Disciplines covered include biomechanics and mechanobiology at all scales, bioengineering and use of tissue engineering and biomaterials for clinical applications, biophysics, as well as biomechanical aspects of medical robotics, ergonomics, physical and occupational therapeutics and rehabilitation.
