目的：观察中药熏洗结合穴位刺激对膝关节前交叉韧带（ACL）保残重建术后本体感觉功能恢复的影响。方法：选取2022年6月至2023年10月因外伤引起的单侧ACL断裂患者105例为研究对象。按随机数字表法分为观察组（35例）、对照1组（35例）及对照2组（35例）。3组均在关节镜下利用自体肌腱保残重建ACL。术后对照1组进行常规康复训练，对照2组进行常规康复训练和平衡促进训练，观察组进行常规康复训练联合中药（骨伤康复外洗颗粒）熏洗及穴位刺激治疗。比较3组手术情况及术后肿痛、关节积液等并发症发生率。术后6周、3个月，3组均行Lachman试验和轴移试验；术前及术后6周、3个月，进行3组Lysholm评分、膝关节功能主观评价表（IKDC）评分、膝关节活动度（ROM）、膝关节重现角度差值、被动运动察觉阈值（TDPM）试验评价比较。结果：3组手术时间、完全负重时间、住院时间比较差异均无统计学意义（P>0.05）。术后6周、3个月3组Lysholm评分、膝关节功能主观评价表（IKDC）评分、ROM均高于术前，且观察组、对照2组均高于对照1组（P<0.05）；术后6周、3个月观察组和对照2组Lysholm评分、IKDC评分、ROM比较差异均无统计学意义（P>0.05）。术后6周、3个月3组膝关节重现角度差值、TDPM值均低于术前，且观察组低于对照1组和对照2组（P<0.05）；对照2组膝关节重现角度差值、TDPM值均低于对照1组（P<0.05）。术后6周、3个月，3组Lachman试验和轴移试验均为阴性。观察组术后肿痛、关节积液并发症发生率均低于对照1组和对照2组（P<0.05）。结论：中药熏洗结合穴位刺激可改善ACL保残重建术后本体感觉功能的恢复，减少术后早期肿痛、关节积液等并发症的发生，是中医外治法促进ACL保残重建术后康复的安全可靠方案。

Objective:To investigate the effect of Chinese medicinals fumigation and washing combined with acupoint stimulation on the recovery of proprioception function after anterior cruciate ligament(ACL) reconstruction of knee joint. Methods:From June 2022 to October 2023,105 patients with unilateral ACL rupture caused by trauma were selected. Patients were divided into observation group(35 cases),control group 1(35 cases),and control group 2(35 cases) by random number table method. In all three groups autologous tendons were used to reconstruct ACL under arthroscopy. After surgery,control group 1 received routine rehabilitation training,control group 2 received routine rehabilitation training and balance promotion training,and the observation group received routine rehabilitation training combined with Gushang Kangfu Waixi Granules（骨伤康复外洗颗粒） fumigation and acupoint stimulation treatment. The surgical conditions and incidence of complications such as postoperative swelling,pain,and joint effusion among the three groups were compared. Six weeks and 3 months after surgery,all three groups underwent the Lachman test and axial shift test. Before surgery,and 6 weeks and 3 months after surgery,the Lysholm score,International Knee Documentation Committee(IKDC) score,knee joint range of motion(ROM),knee joint recurrence angle difference,and passive motion perception threshold(TDPM) tests of three groups were evaluated and compared. Results:There was no statistically significant difference in surgical time,complete weight-bearing time,and hospital stay time among the three groups(P>0.05). The Lysholm score,IKDC score,and ROM of the three groups 6 weeks and 3 months after surgery were all higher than those before surgery,and in the observation group and control group 2 were all higher than those in the control group 1(P<0.05);there was no statistically significant difference in Lysholm score,IKDC score,and ROM before and after 6 weeks and 3 months of surgery between the observation group and the control 2 group(P>0.05). The difference in knee joint recurrence angle and TDPM 6 weeks and 3 months after surgery in the three groups were lower than those before surgery,and in the observation group were lower than those in the control group 1 and control group 2(P<0.05);the knee joint recurrence angle and TDPM in control group 2 were lower than those in control group 1(P<0.05). Six weeks and 3 months after surgery,results of Lachman test and axial shift test in all three groups were negative. The incidence of complications such as postoperative swelling and pain,and joint effusion in the experimental group was lower than that in the control group 1 and control group 2(P<0.05). Conclusions:Chinese medicinals fumigation and washing combined with acupoint stimulation could improve the recovery of proprioception function after ACL reconstruction and reduce the incidence of early postoperative swelling and pain,joint effusion and other complications. It is a safe and reliable protocol for external treatment by traditional Chinese medicine to promote the rehabilitation after ACL reconstruction.
