Abstract

Background

The second generation of a custom total knee arthroplasty (TKA) implant cast from a 3D-printed mold was introduced into the market in 2012. The purpose of this retrospective study was to investigate short- to mid-term survivorship and complication rates of this novel implant.

Methods

This study is a retrospective analysis of 314 TKA procedures (264 patients) performed by a single surgeon using a customized TKA from September 2012 to November 2015. Patient demographics, rate of implant revision, rate of reoperation for any reason, and rate of postoperative complications were recorded.

Results

At the time of index surgery, the mean patient age was 64.7 years, and the mean follow-up duration was 3 years. At the final follow-up, implant survivorship free from revision was 98.1%, and survivorship free from reoperation for any reason was 92.4%.

Conclusions

Our analysis revealed favorable short- to mid-term survivorship for a customized TKA implant. While the short- to mid-term outcomes for this implant are promising, future studies are required to assess long-term outcomes and durability.

根据 3D 打印模具铸造患者专用全膝关节置换术假体的早期结果

背景第二代定制全膝关节置换术（TKA）植入体由 3D 打印模具铸造而成，于 2012 年投放市场。本回顾性研究旨在调查这种新型植入体的中短期存活率和并发症发生率。方法本研究是对 2012 年 9 月至 2015 年 11 月期间由一名外科医生使用定制 TKA 进行的 314 例 TKA 手术（264 名患者）的回顾性分析。研究记录了患者的人口统计学特征、植入物翻修率、因任何原因再次手术率以及术后并发症发生率。结果在进行指数手术时，患者的平均年龄为 64.7 岁，平均随访时间为 3 年。结论我们的分析显示，定制 TKA 植入体的中短期存活率良好。虽然这种假体的中短期疗效很好，但还需要未来的研究来评估其长期疗效和耐久性。
