Objective： To observe the clinicaleffect of Xibazhen com bined with traditionalacupuncture for chondrom alacia patellae.Methods：Divided 90 cases of patients with chondrom alacia patellae into the control group 1，the control group 2and the observation group randomly，30 cases in each group.The control group 1 was given traditional acupuncture，and the control group 2 was given Xibazhen for treatment，while the observation group was given Xibazhen com bined with traditional acupuncture.The treatment of the three groups lasted for one course，once every other day，10 times a course.Compared the clinical effect，Lysholm scores and visual analogue scale(VAS)scores of the patella grinding test in the three groups before and after treatment.Results：After treatment，the totaleffective rate was 33.3%in the control group 1，100%in the control group 2 and the observation group，when compared the total effective rate of control group 2 and observation group with the control group 1，differences being significant( P ＜0.05).There was no significant difference being found in the comparison of the totaleffective rate in the observation group and the control group 2( P ＞ 0.05).After treatment，the Lysholm scores of the three groups were decreased when compared with those before treatment.The decrease of Lysholm score in the observation group and control group 2 was more significant than that in the control group 1 and the control group 2( P ＜0.05).There was no significant difterence being found in the comparision of the Lysholm score of control group 2 and observation group(P＞ 0.05).After treatment，the VAS scores of patella grinding test in the three groups were lower than those before treatment，and the decrease of VAS scores of the patella grinding test in the observation group and the control group 2 were significantly lower than that in the controlgroup 1( P ＜0.05)；there was no significant difference being found in the comparison of the VAS score of the patella grinding test in the observation group and the control group 2( P ＞0.05).Conclusion：The application of Xibazhen for chondrom alacia patellae is more effective than traditional acupuncture and it can achieve good results without the need for adjunct points.With exactcurative effects，it can relieve pain of patients，improve knee joint function，and provide a new point selection principle for improving the clinical effect of acupuncture and moxibustion in treating chondrom alacia patellae.
