To study the functional exercise combined with Chinese medicine fumigation and washing in the application of anterior cruciate ligament after reconstruction rehabilitation treatment. Methods:A total of 70 patients with anterior cruciate ligament reconstruction rehabilitation treatment from March 2013 to February 2013 in our hospital, were divided into trial group and control group according to the stochastic indicator method, with 35 cases in each group. Control group were treated with functional exercise, the trial group were given Chinese medicine fumigation and washing on the basis of control group. Patients of two groups in the preoperative and postoperative 6 months of HSS knee joint function score, visual analogue scale, knee joint ache, limb joint mobility thigh circumference and joint muscle strength changes were compared. Results:After treatment, the good rate of trial group was 88.57% (31/35), significantly higher than the control group′s 54.28% (19/35) (P<0.05). And 6 months after the surgery, trial groups′ HSS knee joint function score (93.15±1.11) points were higher than the control group (84.36±2.56) points, visual analog pain score (1.94±0.24) points lower than the control group (3.56±0.52)points, two groups had significantly difference (P<0.05). Enrichment of motion (121.14±13.56)degrees of trial group were higher than control group (107.32±12.11) degrees, lateral thigh circumference difference between the healthy and affected side of the trial group was(1.84±0.21) cm, significantly lower than the control group (2.21±0.45) cm (P<0.05). The quadriceps peak torque, darkthrone rope muscle peak torque, total energy, darkthrone rope quadriceps muscle total energy of the trial group were ［(73.24±7.32 mm)n·m, (46.32±6.15)n·m, (674.36±45.22)J, (654.61±42.15)J］ respectively, significantly higher than the control group′s ［(51.43±5.19 mm)n·m, (33.56±3.67)n·m, (542.15±34.32)J, (514.24±23.56)J］ (P<0.05). Conclusion:The functional exercise combined with Chinese medicine fumigation and washing can relieve the knee joint pain and improve its activity, promote the recovery of knee joint function in the application of anterior cruciate ligament after reconstruction rehabilitation treatment.
