Detailed understanding of the knee joint loading requires the calculation of muscle and joint forces in different conditions. In these applications the patellar tendon moment arm length is essential for the accurate estimation of the tibiofemoral joint loading. In this article, different methods that have been used to determine the patellar tendon moment arm length under in vivo and in vitro conditions are reviewed. The limitations and advantages associated with each of the methods are evaluated together with their applications in the different loading conditions that the musculoskeletal system is subjected to. The three main measurement methods that this review considers are the geometric method, the tendon excursion method and the direct load method. A comparison of relevant quantitative results is presented to asses the impact of the errors of each method on the quantification of the patellar tendon moment arm and the implications for joint loading assessment in clinical applications.
对膝关节负荷的详细了解需要计算不同条件下的肌肉和关节力。在这些应用中，髌腱力臂长度对于准确估计胫股关节负荷至关重要。本文综述了在体内和体外条件下用于确定髌腱力臂长度的不同方法。评估了每种方法的局限性和优点，以及它们在肌肉骨骼系统所承受的不同负荷条件下的应用。本综述考虑的三种主要测量方法是几何法、肌腱偏移法和直接负荷法。给出了相关定量结果的比较，以评估每种方法的误差对髌腱力臂量化的影响以及对临床应用中关节负荷评估的意义。
