The Gunston polycentric knee arthroplasty, first designed and performed by Frank Gunston in 1971, is the first prosthesis considering the natural knee biomechanics. Although the polycentric knee arthroplasty showed encouraging results to relieve pain and to preserve the preoperative range of motion and joint instability, the improvements in prosthesis design and arthroplasty technology rapidly made the polycentric knee prosthesis obsolete. Herein, we report a 58-year old male patient who had revision of the Gunston polycentric knee arthroplasty with total knee arthroplasty performed 32 years after the initial operation.
冈斯顿多中心膝关节置换术由弗兰克·冈斯顿于1971年首次设计并实施，是首个考虑自然膝关节生物力学的假体。尽管多中心膝关节置换术在缓解疼痛、保留术前活动范围和关节稳定性方面显示出令人鼓舞的结果，但假体设计和关节置换技术的进步迅速使多中心膝关节假体过时。在此，我们报告一名58岁男性患者，他在初次手术后32年接受了冈斯顿多中心膝关节置换术翻修，采用了全膝关节置换术。
