Degenerative or inflammatory diseases of the knee joint account for a large proportion of diseases affecting the elderly. Treatment aims to eliminate pain, correct the deformity and maintain complete joint mobility. In cases of total joint degeneration, fitting of a joint prosthesis is the technique currently favoured since elimination of pain and correction of the deformity, accompanied by recovery of joint mobility (the fundamental requirements for normal everyday life) can only be obtained if the knee joint is completely replaced. With the discovery of new materials and increasingly sophisticated knowledge about articular mechanics, the knee prosthesis, although more recent than the hip prosthesis, has become ever more widespread to the point that it now represents an irreplaceable aid in the treatment of this common disease. The clinical results obtained are already stable and particularly encouraging and prosthesis design is sophisticated and accurate. There is, however, still the suspicion that current prostheses can be considered "rudimentary" in comparison with the physiological and biomechanical behaviour of the human joint. We therefore wanted to begin an evaluation using a gait analysis system to assess patients fitted with knee prostheses. The first impressions gained in this study are the subject of this article.
膝关节的退行性或炎症性疾病在影响老年人的疾病中占很大比例。治疗旨在消除疼痛、纠正畸形并保持关节的完全活动能力。在全关节退变的情况下，安装关节假体是目前首选的技术，因为只有完全置换膝关节，才能消除疼痛、纠正畸形，并恢复关节活动能力（这是正常日常生活的基本要求）。随着新材料的发现以及对关节力学的认识日益深入，膝关节假体尽管比髋关节假体出现得晚，但已越来越广泛地应用，以至于现在它已成为治疗这种常见疾病不可替代的辅助手段。所获得的临床结果已经稳定且特别令人鼓舞，假体设计精密且精确。然而，仍然有人怀疑，与人体关节的生理和生物力学行为相比，目前的假体可被视为“原始的”。因此，我们希望开始使用步态分析系统对安装膝关节假体的患者进行评估。本文介绍了这项研究的初步印象。
