Abstract

Objective: The objective of the research was to carry out a comparative study between Smith & Nephew ® or Zimmer ® prostheses with thick versus thin polyethylene, in patients undergoing primary total knee arthroplasty, during a short-term follow-up. Thus, the objective was to analyze the survival of the implants in question under the clinical and radiographic aspect.

Methods: The sample was divided into two groups: Group 1 with thick polyethylene and group 2 with thin polyethylene. A clinical analysis of the patients was carried out and the implants were checked for loosening.

Results: The groups were similar when compared. According to the Ahlbäck classification, 83% of the patients were in groups IV and V. The median functional score in the postoperative period was similar between the two groups. Postoperatively, the tibiofemoral angle fluctuated between 5 and 6 ⁰ valgus on average. Two complications were observed in each group. None of the evaluated patients presented implant loosening.

Conclusion: Patients treated with thick polyethylene had the same functional score as the control group, as well as the absence of radiographic changes in this short-term follow-up, with implant survival and a similar rate of complications between both groups. Level of evidence III, Retrospective study.

初级全膝关节置换术中聚乙烯厚度的短期评估。

研究目的该研究旨在对接受初级全膝关节置换术的患者进行短期随访，比较 Smith & Nephew ® 或 Zimmer ® 假体的聚乙烯材质厚薄。因此，我们的目的是从临床和放射学角度分析相关假体的存活率：方法：样本分为两组：方法：样本分为两组：第一组使用厚聚乙烯，第二组使用薄聚乙烯。对患者进行了临床分析，并检查了种植体的松动情况：结果：两组比较结果相似。根据 Ahlbäck 分级法，83% 的患者属于 IV 组和 V 组。术后，胫骨与股骨的夹角平均在外翻 5 至 6 0 之间波动。两组患者均出现了两种并发症。结论：结论：使用厚聚乙烯材料治疗的患者与对照组患者的功能评分相同，在短期随访中也没有出现影像学变化，两组患者的植入物存活率和并发症发生率相似。证据等级 III，回顾性研究。
