Abstract: ［Abstract］  Objective〖HTSS〗〓To explore the role of painless management in patients after total knee arthroplasty.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Sixtyeight patients with severe osteoarthritis were divided into two groups: observation group and control group, 34 cases in each group. They were calculated with clinical data, diagnosis and treatment, and prognosis.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓Preoperative Lysholm score was no significant difference between the two groups. The Visual Analogue Scale(VAS) of the observation group before discharge was significantly lower than that of the control group, and the range of motion(ROM) of the observation group before discharge was better than that of the control group, the difference of VAS score and ROM was statistically significant(P＜005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓Multimode analgesia can effectively increase the awareness of preoperative active exercise through a series of postoperative rehabilitation methods. It can also reduce the rest and movement pain of patients after operation and ensure the success of postoperative rehabilitation plan and patient satisfaction.
