Currently, an increase in resurfacing arthroplasty in the treatment of hip osteoarthritis--especially in young adults--can be observed. New bearing technologies (mainly metal-on-metal surfaces) show better tribologic results than historical designs (e.g. the Wagner cup). At present, it is unclear whether these modifications and a definitively low dislocation rate--due to the large head diameter--can be supported by further good clinical results. The quantity as well as the quality of the available investigations prevents a definite opinion at the moment. Appropriate clinical studies with documented radiographic follow-up are necessary to compare the outcome of these new implants with standard techniques.
目前，可以观察到髋关节置换术在治疗髋骨关节炎方面的应用有所增加，尤其是在年轻成年人中。新的轴承技术（主要是金属对金属表面）比传统设计（如瓦格纳杯）显示出更好的摩擦学效果。目前尚不清楚这些改进以及由于大头直径导致的明显较低的脱位率是否能得到进一步良好临床结果的支持。现有研究的数量和质量目前还无法得出明确结论。需要进行适当的临床研究，并记录影像学随访结果，以便将这些新植入物的结果与标准技术进行比较。
