Abstract

Objective: The objective of the article was to do a comparative study between Smith & Nephew ® prosthesis with constricted polyethylene against the standard in patients submitted to total knee arthroplasty surgery during a short-term follow-up. The aim was to analyze the survival of the related implants due to the range of movement and radiographic aspect.

Methods: The sample was divided into two different groups: constricted polyethylene and standard polyethylene. A clinical analysis of the patients was carried out, and it was verified whether implant loosening had occurred.

Results: This study evaluated 61 patients in a period of 2 years, 29 in the constricted polyethylene group. The pre-operative deformities were predominantly considered severe. In the postoperative, the tibial-femoral angle varied on average between 5 - 6° of valgus. The total range of movement in the post-operative was above 101° in both groups. One loosened implant in the constricted polyethylene group was observed.

Conclusion: The patients treated with constricted polyethylene had the same range of movement as the control group. There was no significant difference between both groups related to loosened implants in short-term follow-up. Level of evidence III; Retrospective study.

压缩聚乙烯与后稳定聚乙烯的atk1a的比较研究。

目的：本文的目的是在短期随访期间对接受全膝关节置换术的患者进行Smith & Nephew®收缩聚乙烯假体与标准假体的比较研究。目的是分析由于活动范围和放射学方面相关植入物的存活。方法：将样品分为压缩聚乙烯组和标准聚乙烯组。对患者进行临床分析，验证是否发生种植体松动。结果：本研究对61例患者进行了为期2年的评估，其中29例为缩窄聚乙烯组。术前畸形主要被认为是严重的。术后胫股角平均外翻5 ~ 6°。两组患者术后总活动范围均在101°以上。缩窄聚乙烯组观察到1例植入物松动。结论：缩窄聚乙烯治疗组患者活动范围与对照组相同。短期随访中，两组间种植体松动无显著差异。证据等级III；回顾性研究。
