The anterior cruciate ligament (ACL) reconstruction mostly relies on the experience of surgeons. To improve the effectiveness and adaptability of the tension after ACL reconstruction in knee joint rehabilitation, this paper establishes a lateral force measurement model with relaxation characteristics and designs an on-line stiffness measurement system of ACL. In this paper, we selected 20 sheep knee joints as experimental material for the knee joint stability test before the ACL reconstruction operation, which were divided into two groups for a comparative test of single-bundle ACL reconstruction through the anterolateral approach. The first group of surgeons carried out intraoperative detection with routine procedures. The second group used ACL on-line stiffness measurement system for intraoperative detection. After that, the above two groups were tested for postoperative stability. The study results show that the tension accuracy is (- 2.3 ± 0.04)%, and the displacement error is (1.5 ± 1.8)%. The forward stability, internal rotation stability, and external rotation stability of the two groups were better than those before operation (前交叉韧带重建张力的设置主要依靠外科医生的经验。为提高膝关节恢复治疗中前交叉韧带重建后张力的有效性和适应性，本文建立具有松弛特性的侧向力学测量模型，设计前交叉韧带在线刚度测量系统，提出“术前检测，术中参考”的新方法。本文选取 20 个绵羊膝关节进行膝关节稳定性测试，分两组进行前外侧入路单束前交叉韧带重建对比实验，第一组手术医生常规流程进行术中检测；第二组使用前交叉韧带在线刚度测量系统在术中进行检测；之后对上述两组进行术后稳定性实验。研究结果表明，该测量系统测量的张力精度为（− 2.3 ± 0.04）%，位移误差为（1.5 ± 1.8）%，术后对两组进行前向稳定性、内旋稳定性和外旋稳定性测试，结果均优于术前（ |
