Efficacy of acupuncture during post-acute phase of rehabilitation after total knee arthroplasty

AbstractObjectiveThe purpose of this study was to determine whether acupuncture is effective in reducing pain and swelling around the knee and improving range of motion (ROM) during the post-acute phase of rehabilitation after total knee arthroplasty (TKA).MethodsFollowing TKA, 80 knees in 80 patients were randomly assigned to either an acupuncture treatment group (Group A) or a control group (Group C). In Group A, the complementary treatment of acupuncture was performed three times/week from postoperative day 7 until postoperative day 21. Outcome measures were: i) pain as assessed by a visual analog scale; ii) reduction of swelling around the knee as indicated by its circumference at the center of the patella; and iii) ROM of the affected knee.ResultsGroup A patients had significantly reduced pain and swelling around the knees and earlier recovery of ROM than did those in Group C.ConclusionAcupuncture provides effective treatment during the post-acute phase of rehabilitation after TKA with respect to pain relief, reduction of swelling around the knee, and early recovery of ROM
