In a retrospective study we compared 32 HINTEGRA total ankle replacements (TARs) and 35 Mobility TARs performed between July 2005 and May 2010, with a minimum follow-up of two years. The mean follow-up for the HINTEGRA group was 53 months (24 to 76) and for the Mobility group was 34 months (24 to 45). All procedures were performed by a single surgeon. There was no significant difference between the two groups with regard to the mean AOFAS score, visual analogue score for pain or range of movement of the ankle at the latest follow-up. Most radiological measurements did not differ significantly between the two groups. However, the most common grade of heterotopic ossification (HO) was grade 3 in the HINTEGRA group (10 of 13 TARs, 76.9%) and grade 2 in the Mobility group (four of seven TARs, 57.1%) (p = 0.025). Although HO was more frequent in the HINTEGRA group (40.6%) than in the Mobility group (20.0%), this was not statistically significant (p = 0.065).The difference in peri-operative complications between the two groups was not significant, but intra-operative medial malleolar fractures occurred in four (11.4%) in the Mobility group; four (12.5%) in the HINTEGRA group and one TAR (2.9%) in the Mobility group failed (p = 0.185).
在一项回顾性研究中，我们比较了 2005 年 7 月至 2010 年 5 月期间进行的 32 例 HINTEGRA 全踝关节置换术（TAR）和 35 例 Mobility TAR，随访时间至少为两年。HINTEGRA 组的平均随访时间为 53 个月（24 至 76），Mobility 组为 34 个月（24 至 45）。所有手术均由一位外科医生完成。在 AOFAS 评分、疼痛视觉模拟评分或踝关节活动范围的最新随访中，两组之间没有显著差异。大多数影像学测量在两组之间没有显著差异。然而，HINTEGRA 组最常见的异位骨化（HO）分级为 3 级（13 例 TAR 中的 10 例，76.9%），而 Mobility 组为 2 级（7 例 TAR 中的 4 例，57.1%）（p = 0.025）。尽管 HINTEGRA 组（40.6%）HO 的发生率高于 Mobility 组（20.0%），但差异无统计学意义（p = 0.065）。两组之间围手术期并发症的差异无统计学意义，但 Mobility 组术中发生内踝骨折 4 例（11.4%），HINTEGRA 组 4 例（12.5%），1 例 Mobility 组 TAR 失败（p = 0.185）。
