The Analgesic Of Pain Control And Joint Activity Improved Effect Of Electroacupuncture After Total Knee Arthroplasty

Objectives:This randomized and controlled study was conducted to assess electroacupuncture (EA) for pain control and joint activity improved during the days following total knee arthroplasty(TKA). Levels of pain were monitored using Visual Analogue Score (VAS),and the activity of knee joint was monitored by the range of motion (ROM).Methods:Thirty-two patients, including6males and26females, undergoing primary unilateral TKA between December,2012and October,2013at Putian College aff.Hospital were randomly assigned to one of two groups:(1) EA group, hospitalization numbers ending in16patients between00-50;(2) control group, hospitalization numbers ending in16patients between00-50.All participants were agree with this study, The indication for primary TKA was rendered by a single surgical specialist. Tourniquet time was30(?)5minutes and duration of surgery was120(?)20minutes.2cases General anesthesia (1patient in EA group and1patient in control group),30cases Combined Spinal-Epidural Anesthesia(CSEA). A standard oral CELEBREX200mg bid, continuous intravenous analgesia, continuous passive motion (CPM) was routinely instituted after TKA,24(?)2hours after surgery upon HemoVac, encourage bilateral knee, ankle and each toe active motion when the anesthetic wears off. Postoperative analgesia pump according to the same recipe prepared by the anesthesiologist,3d postoperative analgesia pump removal. The EA group received electroacupuncture for half an hour in Day1(upon HemoVac removal), Day2, Day3, Day5, Day7, Day10, Day12and Day14dressing after TKA. The control group did not.EA by the acupuncture physician with a professional using the same brand of acupuncture needles, electro-acupuncture device, select the same point operations.Outcomes were expressed in terms of VAS pain score, active range of motion (ROM) with knee flexion and extension (in supine position). Data were obtained at four points in time-Day3, Day7, Day10and Day14after TKA. Active ROM with knee flexion and extension was assessed each time by the same individual with a goniometer.Mean and standard deviation were calculated for all parameters. Raw data were analyzed with Statistical Package for Social Science (SPSS) version17.0. The Independent Samples Test and Mann-Whitney Test were used to evaluate group differences. Statistical significance was set at P<0.05.Results: Electro-acupuncture treatment can significantly reduce early postoperative pain levels after total knee arthroplasty, improve early postoperative activity. EA group on postoperative Day3(POD3) and POD7after surgery was significantly lower than the control group (P<0.05),but at POD14the two groups had no significant difference (P>0.05), indicating that the14th day after TKA (often stitches discharge time) have less pain.EA group was significantly higher degree of joint early activity (P<0.05), But with the degree of pain relief, POD7,10and14activity were no significant differences (P>0.05).Conclusions:LEA can significantly relieve the pain levels after total knee arthroplasty, especially early postoperative, increase patient satisfaction, encourage patients to actively functional exercises;2.EA can improve total knee arthroplasty postoperative range of motion, help patients with early functional exercises, improve living standards and enhance the confidence of rehabilitation.
