使用全膝关节置换术（TKA）治疗膝关节慢性退行性病变已有50年的经验。在此期间，外科医生和工程师之间的合作在假体设计方面取得了许多进展。今天，即使在不断发展中，这种方法也是安全和成熟的。技术的进步和新材料的使用让研究人员再次尝试过去的老式技术，以便改进。这种对这些发现的热情并不总是与科学验证齐头并进：许多悬而未决的问题仍然存在。每种不同的设计概念都试图回答特殊需求，如最高ROM的范围、疼痛和碎片的减少、关节几何形状、固定类型、垫块和股骨柄的模块化、限制类型、膝关节运动学以及当然的成本。
The use of Total Knee Arthroplasty (TKA) in treatment of chronic degenerative pathologies of the knee boasts of an experience of 50 years. During this period the collaboration between surgeons and engineers produced many developments in the design of the prosthesis. Today this procedure is safe and established even if in continuous development. The progress in technologies and the use of new materials let researches try again old-fashioned techniques from the past in order to be improved. This enthusiasm for those discovers is not always going hand to hand with scientific validation: many open questions remains Every different concept of the design tries to answer to special needs as the reach of the highest ROM, the reduction of pain and debris, articular geometry, the type of fixation, the modularity of augments and stems, the types of constraints, knee kinematic and of course costs.
