The aim of this study was to investigate how the Achilles tendon resting angle (ATRA), an indirect measurement of tendon elongation, correlates with ultrasonography (US) measurements of the Achilles tendon length 6 and 12 months after an acute ATR and relates to other clinical outcome measurements such as heel-rise height, jumping ability and patient-reported outcome measurements (PROMs).
Patients were included following acute Achilles tendon rupture (ATR). Achilles tendon length, ATRA, heel-rise height (HRH), drop countermovement jump (Drop CMJ) and PROMs (Achilles tendon total rupture score (ATRS) and physical activity scale (PAS)) were evaluated 6 and 12 months after injury. Achilles tendon length was evaluated using US, while the ATRA was measured with a goniometer.
Sixty patients (13 women, 47 men), mean (SD) age 43 (9) years, with an acute ATR undergoing either surgical (35%) or non-surgical (65%) treatment were evaluated. A negative correlation (r = - 0.356, p = 0.010) between relative ATRA and tendon elongation was seen at 12 months after ATR. There were also significant positive correlations at 6 and 12 months between relative ATRA and HRH (r = 0.330, p = 0.011 and r = 0.379, p = 0.004). There were no correlations between ATRA and ATRS or ATRA and Drop CMJ, at either 6 or 12 months after the injury.
In combination with other clinical evaluations such as HRH and US, ATRA could be a clinical tool for indirect measurements of tendon elongation. However, ATRA cannot be recommended as a direct surrogate for US for determining Achilles tendon length.

本研究旨在探讨跟腱静息角（ATR）作为跟腱拉伸的间接测量指标，与急性跟腱断裂（ATR）后 6 个月和 12 个月时的跟腱长度的超声（US）测量值有何相关性，以及与其他临床结果测量值（如足跟抬高高度、跳跃能力和患者报告的结局测量值（PROMs））有何相关性。
纳入急性跟腱断裂（ATR）患者。在损伤后 6 个月和 12 个月时，评估跟腱长度、ATR、足跟抬高高度（HRH）、反向纵跳（Drop CMJ）和 PROMs（跟腱总断裂评分（ATRS）和身体活动量表（PAS））。使用 US 评估跟腱长度，使用量角器测量 ATRA。
共评估了 60 名患者（13 名女性，47 名男性），平均（SD）年龄 43（9）岁，急性 ATR 分别接受手术（35%）或非手术（65%）治疗。在 ATR 后 12 个月时，相对 ATRA 与跟腱拉伸之间呈负相关（r=-0.356，p=0.010）。在 ATR 后 6 个月和 12 个月时，相对 ATRA 与 HRH 之间也存在显著正相关（r=0.330，p=0.011 和 r=0.379，p=0.004）。在损伤后 6 个月和 12 个月时，ATR 与 ATRS 或 ATRA 与 Drop CMJ 之间均无相关性。
ATR 与 HRH 和 US 等其他临床评估相结合，可能成为间接测量跟腱拉伸的临床工具。然而，ATR 不能被推荐为直接替代 US 来确定跟腱长度。
