Objective. To compare the early clinical outcomes of ACL reconstruction using the augmented semitendinosus tendon combined with LARS synthetic material and the autologous hamstring tendons. Methods. A total of 68 eligible patients with ACL rupture were reconstructed using either 4-strand autologous hamstring tendons, representing the control group, or the LARS synthetic material augmented grafts. The duration of postoperative swelling and recovery exercise was recorded. Lysholm and IKDC scores were used for evaluation of knee joint function. Lachman and pivot shift tests were conducted to evaluate stability. Results. The scores of the three knee functions in cases of the augmentation group were significantly higher than those of the control group 6 months after surgery (). There were no significant differences in Tegner score in the two groups 12 months after surgery (). In general, the augmentation group returned to exercise 12 weeks after surgery, while the control group required 30 weeks. Conclusions. The present study indicates that synthetic material augmentation grafts allow earlier return to exercise and display more satisfactory results compared with the control group.

半腱肌腱联合 LARS 合成 ACL 重建的早期临床结果

客观。比较使用增强的半腱肌腱结合 LARS 合成材料和自体腘绳肌腱重建 ACL 的早期临床结果。方法。共有 68 名符合条件的 ACL 断裂患者使用代表对照组的 4 股自体腘绳肌腱或 LARS 合成材料增强移植物进行重建。记录术后肿胀和恢复运动的持续时间。Lysholm 和 IKDC 评分用于评估膝关节功能。进行拉赫曼和枢轴移位测试以评估稳定性。结果。术后 6 个月，增强组病例 3 项膝关节功能评分显着高于对照组（）。术后 12 个月，两组 Tegner 评分差异无统计学意义（）。一般来说，增强组在术后 12 周恢复运动，而对照组则需要 30 周。结论。本研究表明，与对照组相比，合成材料增强移植物可以更早地恢复运动并显示出更令人满意的结果。
