膝关节以下截肢(BK)患者的膝关节和髋关节骨性关节炎的发生率明显高于未受损伤的患者，尤其是在完好的一侧。然而，除了代谢方面的其他危险因素外，健侧持续较高的负荷是否是BK患者骨关节炎(OA)发病率增加的主要因素之一，仍存在争议。目的是研究由肌肉骨骼模型计算的健侧关节接触力(JCF)，并将其与未受损受试者的关节接触力进行比较，进一步阐明膝关节JCF增加与膝关节额面力矩增加有多大关系。本研究招募了7名BK截肢者和10名正常受试者。通过三维运动捕捉和测力板测量步态数据。应用OpenSim软件计算JCF。最大关节角度、地面反作用力、力矩以及时间距离参数在两组之间进行了测定和比较，显示没有显著差异，BK受试者膝关节和髋关节的某些JCF成分甚至比对照组略小。这一积极的发现可能是由于所选的Esar足部。然而，其他有益的因素也可能影响这一积极的结果，例如受试者的总体健康状况或假体的彻底和适当的装配和对齐。
The incidence of knee and hip joint osteoarthritis in subjects with below knee amputation (BK) appears significantly higher compared to unimpaired subjects, especially in the intact side. However, it is controversial if constant higher loads on the sound side are one of the major factors for an increased osteoarthritis (OA) incidence in subjects with BK, beside other risk factors, e.g. with respect to metabolism. The aim wasto investigate joint contact forces (JCF) calculated by a musculoskeletal model in the intact side and to compare it with those of unimpaired subjects and to further elucidate in how far increased knee JCF are associated with increased frontal plane knee moments. A group of seven subjects with BK amputation and a group of ten unimpaired subjects were recruited for this study. Gait data were measured by 3D motion capture and force plates. OpenSim software was applied to calculate JCF. Maximum joint angles, ground reaction forces, and moments as well as time distance parameters were determined and compared between groups showing no significant differences, with some JCF components of knee and hip even being slightly smaller in subjects with BK compared to the reference group. This positive finding may be due to the selected ESAR foot. However, other beneficial factors may also have influenced this positive result such as the general good health status of the subjects or the thorough and proper fitting and alignment of the prosthesis.
