The correlation between tendon bone healing and clinical functional scores after anterior cruciate ligament reconstruction (ACLR) using four-stranded hamstring tendon autograft has rarely being reported. The purpose of this study was to determine the correlation between magnetic resonance imaging (MRI)-based tendon bone healing and clinical functional scores after ACLR using hamstring tendon.
Thirty-eight patients with ACLR using four-stranded hamstring tendon autograft were included in this prospective study in the authors' hospital from 2013 to 2014. All patients were performed Tegner, Lysholm, International Knee Documentation Committee (IKDC) subjective scores, KT-1000 and MRI examinations in 3, 6, 12 months after the operation, respectively. According to MRI, the healing degree of tendon bone was divided into five grades, and the healing degree of the tendon at different time points was evaluated. Moreover, the correlations between the clinical scores and tendon bone healing level at 12 months after the operation were determined.
The Tegner, Lysholm, and IKDC scores of all patients were gradually improved over time after ACLR, and the degree of tendon bone healing was gradually increased. Moreover, there were significantly positive correlations between the level of tendon bone healing and the clinical functional scores at 12 months after the operation.
The clinical functional scores and the degree of tendon bone healing were gradually improved over time after ACLR. Moreover, there were significant positive correlations between the level of tendon bone healing and clinical functional scores of knee joint at the first year after the operation.

前交叉韧带重建（ACLR）后使用四股腘绳肌腱移植物的肌腱骨愈合与临床功能评分之间的相关性鲜有报道。本研究旨在确定基于磁共振成像（MRI）的肌腱骨愈合与 ACLR 后使用腘绳肌腱的临床功能评分之间的相关性。
2013 年至 2014 年，作者医院对 38 例使用四股腘绳肌腱移植物进行 ACLR 的患者进行了前瞻性研究。所有患者分别在术后 3、6、12 个月进行了 Tegner、Lysholm、国际膝关节文献委员会（IKDC）主观评分、KT-1000 和 MRI 检查。根据 MRI，肌腱骨的愈合程度分为 5 个等级，并评估不同时间点肌腱的愈合程度。此外，还确定了术后 12 个月时临床评分与肌腱骨愈合程度之间的相关性。
所有患者的 Tegner、Lysholm 和 IKDC 评分在 ACLR 后随时间逐渐改善，肌腱骨愈合程度逐渐增加。此外，肌腱骨愈合程度与术后 12 个月的临床功能评分之间存在显著正相关。
ACLR 后，临床功能评分和肌腱骨愈合程度随时间逐渐改善。此外，肌腱骨愈合程度与术后第 1 年膝关节的临床功能评分之间存在显著的正相关。
