Knee prostheses of the condylar or hinge type have constructional features that have both advantages and disadvantages. Both types are compromises as a result of different demands. Here we report long-term results with the Blauth prosthesis as an example of the efficiency of the hinge concept. The Blauth prosthesis is constructed according to the low-friction principle without a weight-bearing axis. Load transmission to the bone is accomplished by large interface areas. The sliding bearing of the patella is oriented perpendicular to the transverse axis of rotation. A prospective multicentric study reports on 511 prosthesis with a follow-up between 1 and 15 years. Aseptic loosenings were confirmed in 1.2% of the patients, deep infections in 3.3%. The survival analysis showed a probability of 89% that a prosthesis would not have a deep infection or loosen. A hinged knee prosthesis shows positive long-term results even compared with the condylar types if the relevant principles of construction are adequately considered.
髁型或铰链型膝关节假体具有一些结构特点，这些特点既有优点也有缺点。由于不同的需求，这两种类型都是折中的产物。在此，我们以布劳思假体为例报告其长期结果，以说明铰链概念的有效性。布劳思假体是根据低摩擦原理构建的，没有负重轴。通过大面积的界面区域将负荷传递至骨骼。髌骨的滑动轴承垂直于旋转横轴定向。一项前瞻性多中心研究报告了511例假体，随访时间为1至15年。1.2%的患者确诊为无菌性松动，3.3%为深部感染。生存分析显示，假体无深部感染或松动的概率为89%。如果充分考虑相关的构造原理，即使与髁型假体相比，铰链型膝关节假体也能显示出良好的长期效果。
