Abstract：【Objective】 To investigate the effect of local drug phonophoresis on pain relief and functional exercise at the early stage after total knee arthroplasty (TKA). 【Methods】 Forty-one patients with unilateral TKA from June 2016 to May 2017 were randomly divided into observation group (n=21) and control group (n=20).Two groups of patients were given the same basic analgesia regimen. From 2 weeks after operation, the patients in the observation group received local ultrasound penetration (lidocaine + betamethasone) for 10 times in 4 weeks. The patients in the two groups were followed up to 3 months after operation. The preoperative activity and AKS scores were recorded respectively. The average activity,visual analogue score (VAS) and AKS score at 2 weeks, 6 weeks and 3 months after operation were recorded respectively. 【Results】 ① There was no significant difference between the two groups in preoperative activity, AKS score, activity at 2 weeks after exercise and VAS score after exercise (P>0.05);② At 6 weeks after operation, the activity of the observation group was (110.0±12.3)°, the VAS score was (2.0±1.0) points, the control group was (102.3±10.4)°,the VAS score was (2.9 ±1.3) points, the difference between the two groups was statistically significant (P<0.05).③ Three months after operation, the activity of the observation group was (116.4±10.7)°, the score of AKS function was (84.0±10.6), the activity of the control group was (111.0±10.9)°, the score of AKS function was (76.0±12.4). The observation group was superior to the control group(P<0.05).【Conclusion】 Ultrasound phonophoresis therapy with lidocaine and betamethasone can effectively relieve postoperative pain after TKA and is helpful to functional rehabilitation of patients with obvious early pain after TKA.
