Changes in stress transferred across articular joints have been described as a substantial factor in the initiation and progression of joint disease such as post-traumatic osteoarthritis and have thus been of interest to biomechanical researchers. However, to date, stress magnitudes within the menisci have not been successfully measured. In this study, a novel method for measuring stress within the menisci is presented. Small Fibre Bragg Grating (FBG) sensors were inserted inside menisci and used to measure mechanical stress during replicated gait cycles. In-vitro stress measurements within the menisci were preformed for healthy gait and gait following surgical damage to the joints. Together with our capability to reproduce in vivo motions accurately, the improvements in fibre optic technology have allowed for the first direct measurement of mechanical stress in menisci.

跨关节关节传递的应力变化已被描述为关节疾病（如创伤后骨关节炎）发生和发展的重要因素，因此引起了生物力学研究人员的兴趣。然而，迄今为止，尚未成功测量半月板内的应力大小。在这项研究中，提出了一种测量半月板内应力的新方法。小型光纤布拉格光栅 (FBG) 传感器插入半月板内，用于测量重复步态周期期间的机械应力。在-体外半月板内的应力测量以下对关节损坏外科预成形为健康步态和步态。连同我们在体内繁殖的能力 为了准确地运动，光纤技术的改进使得首次直接测量半月板中的机械应力成为可能。
