【摘要】 目的：比較不同负重训练时间对关节镜膝关节前交叉韧带重建患者术后关节功能及稳定性的影响。方法：选取2017年3月-2019年5月本院收治的90例关节镜膝关节前交叉韧带重建患者为研究对象，按随机数字表法将其分为A、B、C组，每组30例。A组术后3 d进行负重训练，B组术后5 d进行负重训练，C组术后7 d负重训练。比较三组术前和术后1、12周膝关节功能状态及后抽屉试验结果。比较三组术后1、12周股骨与胫骨骨隧道直径及术后12周膝关节伸直及屈曲受限程度。结果：术后1、12周，三组膝关节功能状态比较，差异均有统计学意义（P<0.05），其中B组优良率最高。术后1、12周，三组后抽屉试验结果比较，差异均有统计学意义（P<0.05），其中B组0级与1级比例最高。术后1、12周，B组股骨与胫骨骨隧道直径均小于A组与C组（P<0.05）。三组术后12周膝关节伸直及屈曲受限程度比较，差异均有统计学意义（P<0.05），其中B组无受限比例最高。结论：术后5 d进行负重训练对关节镜膝关节前交叉韧带重建患者术后膝关节功能及稳定性的影响相对较好，术后5 d为负重训练时机临床价值更高。

[Abstract] Objective： To compare the effects of different weight-training time for the postoperative joint function and stability of patients with arthroscopic anterior cruciate ligament reconstruction. Method： A total of 90 patients with arthroscopic anterior cruciate ligament reconstruction in our hospital from March 2017 to May 2019 were selected as the research objects. According to random number table method， they were divided into group A， B and C， 30 cases in each group. Group A received weight-training at 3 d after surgery， group B received weight-training at 5 d after surgery， and group C received weight-training at 7 d after surgery. The functional status of knee joint and the results of posterior drawer test were compared among the three groups before and at 1 and 12 weeks after surgery. The diameter of the femoral and tibial tunnel at 1 and 12 weeks after surgery and the limitation of knee extension and flexion 12 weeks after surgery were compared among three groups. Result： At 1 and 12 weeks after surgery， there were statistically significant differences in functional state of knee joint among the three groups （P<0.05）， and the excellent and good rate of group B was the highest. At 1 and 12 weeks after surgery， there were statistically significant differences in the results of the posterior drawer test among three groups （P<0.05）， and the ratio of grade 0 to grade 1 was the highest in group B. At 1 and 12 weeks after surgery， the diameter of femur and tibia tunnel in group B were less than those in group A and group C （P<0.05）. There were statistically significant differences in the degree of limitation of knee extension and flexion 12 weeks after surgery among three groups （P<0.05）， and the proportion of no limitation in group B was the highest. Conclusion： The effect of weight-training for the postoperative knee function and stability of patients with arthroscopic anterior cruciate ligament reconstruction at 5 d after surgery is relatively good. 5 d after surgery is the time of weight-training， which has higher clinical value.

膝关节前交叉韧带重建在临床具有较高的应用率，关节镜手术作为微创术式，其在膝关节前交叉韧带重建患者中的应用效果广受肯定。而本类手术效果除受手术方式及技术经验等因素影响较大外，术后的康复锻炼方式及训练时机也是影响疗效及预后的重要方面，因此对关节镜膝关节前交叉韧带重建患者进行负重训练时机的研究需求较高[1-2]。临床中关于本方面的研究虽可见，但是其针对患者术后关节功能及稳定性的影响未见。因此，本研究就不同负重训练时间对关节镜膝关节前交叉韧带重建患者术后关节功能及稳定性的影响进行探究，现报道如下。
