Cohort study.
To describe calf muscle endurance recovery and to explore factors predictive of poor calf muscle endurance recovery 1 year after surgical repair of an Achilles tendon rupture (ATR).
ATR is a common sports-related injury and is often managed with open surgical repair. After ATR repair most patients return to usual activities 6 months after surgery. However, calf endurance impairment can persist up to 6 years, possibly impacting performance of daily activities and sport.
A secondary analysis of a 73-patient cohort from a randomized controlled trial assessing the effects of early weight bearing after surgical repair of an ATR was performed. Calf muscle endurance recovery was measured by single-heel raises using a customized counting device at 6 months and 1 year postoperatively. Descriptive statistics were used to outline recovery of calf muscle endurance. Physical and patient-reported outcomes were examined for their association with calf-muscle endurance recovery. Multiple linear regression analysis was performed to explore variables associated with recovery of calf endurance 1 year postoperatively.
Mean recovery of calf muscle endurance was 76% at 1 year. Multivariate regression analysis showed an association of being female, reporting no resting pain at 3 months, and physical functioning and calf endurance at 6 months, with better recovery of calf endurance at 1 year.
Calf muscle endurance at 1 year remained impaired in a considerable portion of the sample. Pain, gender, and physical functioning are likely important factors in determining recovery of calf muscle endurance.

队列研究。
描述小腿肌肉耐力的恢复情况，并探讨影响跟腱断裂（ATR）手术后 1 年小腿肌肉耐力恢复不良的因素。
ATR 是一种常见的运动相关损伤，通常采用开放式手术修复。在 ATR 修复后，大多数患者在手术后 6 个月即可恢复正常活动。然而，小腿耐力的损害可能持续长达 6 年，这可能会影响日常活动和运动的表现。
对一项评估手术修复 ATR 后早期负重对患者影响的 73 例患者队列的二次分析。使用定制的计数装置在术后 6 个月和 1 年测量单足提踵来评估小腿肌肉耐力的恢复情况。使用描述性统计来概述小腿肌肉耐力的恢复情况。检查身体和患者报告的结果与小腿肌肉耐力恢复的关系。进行多元线性回归分析，以探讨与术后 1 年小腿耐力恢复相关的变量。
1 年后小腿肌肉耐力的平均恢复率为 76%。多变量回归分析显示，女性、3 个月时无静息痛、6 个月时的身体功能和小腿耐力与 1 年后更好的小腿耐力恢复相关。
在样本中，相当一部分患者的小腿肌肉耐力在 1 年后仍然受损。疼痛、性别和身体功能可能是决定小腿肌肉耐力恢复的重要因素。
