Abstract：Objective：To analyze the effect of acupoint needling and rehabilitation training on the recovery and prognosis of knee joint function after anterior cruciate ligament reconstruction. Methods： Selected 160 cases of patients undergoing anterior cruciate ligament reconstruction，and divided them into the experiment group and the control group randomly，80 cases in each group. After operation，the control group received routine rehabilitation training，while the experiment group additionally received acupoint needling rehabilitation measures. Before operation and 4 months after operation，compared the scores of knee joint function via the Hospital for Special Surgery(HSS)，the recovery of proprioception in knee joint [difference values in different flexion angles of knee joint position sense(JPS)] and the scores of quality of life[Medical Outcomes Study- Short From(SF-36)] four months after operation in both groups. Results：Four months after operation，the scores of HSS in both groups were significantly improved than those before treatment(P＜0.05)， and the scores of HSS in the experiment group were higher than those in the control group(P＜0.05). Four months after operation，JPS at the first，second and third sections of flexion angles in both groups were lower than those before treatment，and each index above in the experiment group was lower than that in the control group(P＜0.05). Four months after operation，the scores of physiological function， physical pain，mental health，social functioning and emotional functioning in the experiment group were respectively higher than those in the control group(P＜0.05). Conclusion：After anterior cruciate ligament reconstruction，acupoint needling and rehabilitation training can promote the recovery of proprioception in knee joint，do good for the recovery of knee joint function and improve the quality of life.
