Abstract

PURPOSE

This study aimed to investigate the relationship between periprosthetic osteolysis around the talar component and the amount of talar component subsidence after total ankle arthroplasty (TAA).

METHODS

This study included forty patients who underwent TAA with a mean follow-up of 67.5 ± 17.0 months. The patients were divided into two groups based on the amount of osteolysis around the talar component, as measured by computed tomography at the latest clinic visit: none to 2 mm (N group, n = 20) and greater than or equal to 2 mm (O group, n = 20). The average amount of talar component subsidence, clinical outcomes, and complications were compared between the two groups. In the O group, the correlation between osteolysis and talar component subsidence was evaluated.

RESULTS

The average talar component subsidence was significantly different between the N (0.22 ± 0.94 mm) and O groups (2.12 ± 2.28 mm). Five out of 20 ankles in the O group required revision surgery owing to talar component subsidence. The Japanese Society for Surgery of the Foot scores in the N and O groups were significantly different: 93.5 ± 7.7 and 85.3 ± 15.4, respectively. In the O group, we found that osteolysis tended to develop on the lateral side, and the amount of osteolysis was positively correlated with the talar component subsidence (r = 0.59, P = .007).

CONCLUSION

In the O group, a positive correlation between osteolysis and talar component subsidence was found, and five patients required revision surgery.

摘要

目的

本研究旨在探讨全踝关节置换术后（TAA）距骨假体周围骨溶解与距骨假体下沉量之间的关系。

方法

本研究纳入了 40 例接受 TAA 治疗的患者，平均随访 67.5±17.0 个月。根据 CT 检查在最近一次就诊时测量的距骨假体周围骨溶解程度将患者分为两组：无至 2mm（N 组，n=20）和大于或等于 2mm（O 组，n=20）。比较两组间距骨假体下沉量、临床结果和并发症。在 O 组中，评估了骨溶解与距骨假体下沉量之间的相关性。

结果

N 组（0.22±0.94mm）和 O 组（2.12±2.28mm）的平均距骨假体下沉量差异有统计学意义。O 组中有 5 例因距骨假体下沉而行翻修手术。N 组和 O 组的日本足踝外科协会评分分别为 93.5±7.7 和 85.3±15.4，差异有统计学意义。在 O 组中，我们发现骨溶解倾向于发生在外侧，骨溶解的程度与距骨假体下沉量呈正相关（r=0.59，P=0.007）。

结论

在 O 组中，我们发现骨溶解与距骨假体下沉量之间存在正相关，有 5 例患者需要翻修手术。
