旋转平台人工全膝关节系统在全膝关节置换术中的应用研究

目的探讨旋转平台人工膝关节置换术（TKA）的临床疗效。方法对21例患者（25膝）行TKA，采用正中切口髌旁内侧入路，对髌骨行去神经化和修复术，安装假体，膝关节均未进行髌骨置换。术后复查X线观察假体固定情况，采用美国膝关节学会评分（KSS评分）评定膝评分及膝功能评分，观察并发症（旋转平台脱位、翻修或感染）发生情况。结果本组随访时间25—37个月（平均28．2个月），X线显示假体均无松动、无髌骨脱位；膝评分为94分（82～98分），功能评分为94分（66—99分）；未出现并发症。结论旋转平台人工全膝关节系统用于TKA近期疗效确切，尤适于年轻、活动量大者；其长期疗效有待进一步观察。

Application of mobile bearing total knee system in the total knee arthroplasty

Objective To investigate the clinical effecs of mobile bearing total knee arthroplasty(TKA).Methods Twenty-one patients(25 knees) were performed TKA by midline incision and side-patella approach,the patella was treated with denervation and reparation,and then prosthesis was performed without replacements of patella.The fixation of prosthesis was observed by X-ray reexamination,the knee score and knee function score were evaluated by KSS scoring,and the complications(rotation plate dislocation,revisionor,inf...
