Objective:To observe the clinical efficacy and safety of knee-balancing Tuina(Chinese therapeutic massage)manipulation for pes anserina bursitis(PAB). Methods:A total of 64 patients with PAB were enrolled and divided into a Tuina group and a medication group by the random number table method,with 32 cases in each group.The medication group was given votalin for external use,and the Tuina group was given knee-balancing Tuina manipulation based on treatment according to structure differentiation.Both groups were treated for 7 consecutive days.The visual analog scale(VAS)score,Lyshlom score,knee joint range of motion(ROM),and total effective rate were compared between the two groups.Adverse reactions were observed in both groups. Results:During the treatment,there was 1 dropout case in the medication group.The total effective rate was 93.8%in the Tuina group and 83.9%in the medication group.The difference between the two groups was statistically significant(P<0.05).After treatment,the VAS score in both groups decreased significantly(P<0.05),and the Lyshlom score and knee joint ROM increased significantly(P<0.05).The differences in the VAS score,Lyshlom score,and knee joint ROM between the two groups were all statistically significant(P<0.05). Conclusion:The knee-balancing Tuina manipulation based on treatment according to structure differentiation can effectively relieve pain and improve knee function in PAB,and its efficacy is superior to that of external use of votalin.
