Abstract

Objective

To present the indications, technical aspects, and initial results of the first cases using Endo-Model™ implants in Brazil.

Methods

A prospective study was conducted. It included nine patients submitted to a total knee arthroplasty, of which six were primary and three were revisions, using exclusively the Endo-Model™ implant. These patients were followed for an average of 12 months and evaluated with functional scores, such as the Knee injury and Osteoarthritis Outcome Score (KOOS), Knee Society Score (KSS), and visual analog pain scale (VAS).

Results

There were statistically significant improvements in all scores evaluated in every patient. Only one complication occurred postoperatively (apraxia of the peroneal nerve) and did not require surgery revision.

Conclusion

The use of a rotating-hinge implant for knee arthroplasty is a new option for complex cases with severe instability in Brazil; the initial results are satisfactory.

膝关节置换术与旋转铰链植入物:复杂的原发性病例和修订的一种选择

目的介绍巴西第一批使用Endo-Model™植入物的适应症、技术方面和初步结果。方法采用前瞻性研究。该研究包括9例接受全膝关节置换术的患者，其中6例为原发性膝关节置换术，3例为修复性膝关节置换术，全部使用Endo-Model™植入物。这些患者平均随访12个月，并通过功能评分进行评估，如膝关节损伤和骨关节炎结局评分(oos)、膝关节社会评分(KSS)和视觉模拟疼痛量表(VAS)。结果所有患者的各项评分均有统计学意义上的改善。术后仅发生一例并发症(腓神经失用)，无需手术翻修。结论在巴西，使用旋转铰链假体进行膝关节置换术是治疗严重不稳定的复杂病例的一种新选择;初步结果令人满意。
