Abstract

Background: To date, little is known about the relationship between implant positioning and TAA outcomes. This study aimed to evaluate how implant size and positioning influence clinical outcomes after TAA.

Methods: In a retrospective review, 89 best and 89 worst cases were selected from 471 ankles based on clinical outcomes after primary TAA surgery. Tibiotalar joint line level, talar height, talar radius, anteroposterior position of the talus, and lateral tibial surface angle were measured on standard X-rays and correlated with clinical outcome measures.

Results: Talar height was the only parameter correlated with ROM; it increased more in the good-progressing group (p = 0.031). ROM increased in the good-progressing group (p = 0.001) but not in the bad-progressing group (p = 0.141).

Conclusions: Although the joint line level and component positioning did not differ between groups, clinical outcomes and ROM were higher in the good-progressing group, suggesting the influence of other factors, such as soft-tissue condition.

Level of evidence: Level III, retrospective review of prospectively collected data.

全踝关节置换术中恢复踝关节对临床疗效和活动范围的影响。

背景：迄今为止，关于种植体定位与TAA结果之间的关系知之甚少。本研究旨在评估种植体大小和定位对TAA后临床结果的影响。方法：回顾性分析471例踝关节TAA术后临床结果，选取最佳89例，最差89例。在标准x线片上测量距骨关节线水平、距骨高度、距骨半径、距骨前后位和胫骨外侧面角，并与临床结果测量相关。结果：距骨高度是唯一与ROM相关的参数；在进展良好的组中增加更多（p = 0.031）。进展良好组的ROM增加（p = 0.001），但进展不良组的ROM没有增加（p = 0.141）。结论：虽然两组间关节线水平和假体定位无差异，但进展良好组的临床结局和ROM均较高，提示存在软组织状况等其他因素的影响。证据等级：III级，前瞻性收集数据的回顾性评价。

期刊介绍： Foot and Ankle Surgery is essential reading for everyone interested in the foot and ankle and its disorders. The approach is broad and includes all aspects of the subject from basic science to clinical management. Problems of both children and adults are included, as is trauma and chronic disease. Foot and Ankle Surgery is the official journal of European Foot and Ankle Society. The aims of this journal are to promote the art and science of ankle and foot surgery, to publish peer-reviewed research articles, to provide regular reviews by acknowledged experts on common problems, and to provide a forum for discussion with letters to the Editors. Reviews of books are also published. Papers are invited for possible publication in Foot and Ankle Surgery on the understanding that the material has not been published elsewhere or accepted for publication in another journal and does not infringe prior copyright.
