These studies are intended as a critical contribution to the question, wether the McKee-Farrar (MF) prosthesis, on account of its stronger friction and the consequences of this, as compared to other models, still has its justification or wether these "secundary" manifestations indicate that this prosthesis should be abandoned. Studies on primary and secundary alteration of the surface were carried out on exchanged MF prosthesis with the aid of the grid electron microscope. The signs of wear are clearly visible and can be differenciated from production artefacts. The movement and deposit of abraded particles into the new joint capsule was studied qualitatively and quantitatively with the aid of radioisotopes. All samples showed an increased accumulation of chrome in the tissues as compared to cobalt. There is no indication of significant damage. On the basis of the results of these studies and on account of the favourable personal experience from a surgical and clinical point of view -- particulary with reference to minimal preparation of the acetabulum and ready replacement, the MF prosthesis will continue to hold its place as the standard model for total prosthetic hip joint replacement.
与其他型号相比，麦基 - 法拉尔（MF）假体因其更强的摩擦力及其后果，是否仍有其存在的合理性，或者这些“继发性”表现是否表明该假体应被摒弃。借助网格电子显微镜，对更换下来的MF假体进行了表面原发性和继发性改变的研究。磨损迹象清晰可见，且能与生产工艺缺陷区分开来。借助放射性同位素，对磨损颗粒在新关节囊内的移动和沉积进行了定性和定量研究。与钴相比，所有样本的组织中铬的积累都有所增加。没有明显损伤的迹象。基于这些研究结果，以及从外科手术和临床角度来看良好的个人经验——特别是髋臼准备简单且易于置换，MF假体将继续作为全髋关节置换的标准模型。
