The clinical and radiographic results of posteromedial release performed on 30 patients (44 feet) were assessed. The patients were divided into three groups based on their average age at the time of operation (early, 4.4 months; middle, 9.1 months; and late, 16.1 months). All patients had similar preoperative deformity, surgical management, and postoperative treatment. The outcomes of all three groups were similar with the exception of hindfoot-to-forefoot alignment and hindfoot varus correction. The early group demonstrated better clinical and radiologic foot alignment and had the lowest incidence of radiologic tarsal deformities (7 vs. 28% in the middle group and 35% in the late group).
对30例患者（44足）进行后内侧松解术的临床和影像学结果进行了评估。根据患者手术时的平均年龄将其分为三组（早期组，4.4个月；中期组，9.1个月；晚期组，16.1个月）。所有患者术前畸形、手术处理和术后治疗均相似。除后足与前足对线及后足内翻矫正外，三组的结果相似。早期组在临床和影像学上足部对线更好，且影像学跗骨畸形的发生率最低（中期组为28%，晚期组为35%，早期组为7%）。
