Oxidized zirconium (OxZr) femoral component for total knee arthroplasty (TKA) have been introduced in an attempt to reduce polyethylene wear and secondary osteolysis and improve longevity of implants.
QUESTIONS/PURPOSES: We reviewed clinical studies in literature evaluating OxZr femoral component for TKA. The aim of this review was to evaluate the clinical outcome and survival rate of TKA with an OxZr femoral component.
A review of the existing literature was undertaken to collect data on the OxZr femoral component in order to provide a better understanding of its performance. Of 34 studies published in the literature, 8 met the eligibility criteria and were included in the final analysis.
Findings indicated that the mean Knee Society knee score improved in all series from preoperative to postoperative evaluation. The postoperative Knee Society knee score reported range from 84 to 95 and mean postoperative Knee Society functional score range from 74 to 90. The revision rate with this implant is low with up to 12.6 years of follow-up, with three revisions in total. The survival rate ranged from 100-98.7% at 5-7 years to 97.8% at 10 years.
Excellent clinical outcome and high survival rate has been demonstrated for OxZr femoral component in TKA. No adverse reaction has been described for this new material.
全膝关节置换术（TKA）中使用的氧化锆（OxZr）股骨部件已被引入，旨在减少聚乙烯磨损和继发性骨溶解，并提高植入物的使用寿命。
问题/目的：我们回顾了文献中评估TKA中OxZr股骨部件的临床研究。本综述的目的是评估采用OxZr股骨部件的TKA的临床结果和生存率。
对现有文献进行回顾，收集有关OxZr股骨部件的数据，以便更好地了解其性能。文献中发表的34项研究中，8项符合纳入标准并被纳入最终分析。
研究结果表明，从术前评估到术后评估，所有系列的膝关节协会膝关节平均评分均有所改善。术后膝关节协会膝关节评分报告范围为84至95，术后膝关节协会功能平均评分范围为74至90。该植入物的翻修率较低，随访长达12.6年，总共进行了三次翻修。5至7年的生存率为100%-98.7%，10年时为97.8%。
TKA中OxZr股骨部件已证明具有出色的临床结果和高生存率。尚未描述这种新材料的不良反应。
