Abstract：Objective:To compare the curative effect and safety of small needle knife therapy and blocking therapy on stenosing tenovaginitis of flexor digitorum by system evaluation. Methods:Randomized controlled trials on treatment of stenosing tenovaginitis of flexor digitorum by small needle knife therapy and blocking therapy as the contrast were retrieved from Chinese national knowledge infrastructure ( 1962~2015 ) , VIP database (1993~2015),WanFang database (2000~2015) and PubMed Chinese database (1994~2015) by computer,as well as related medical journals by manual work. The Meta-analysis was done by the RevMan 5.2 software after the selected data was cross checked by 2 valuators according to the requirements. Re-sults:A total of 7 randomized controlled trials met the inclusion criteria,including 1 174 patients,but there was no high-quality literature. The results of Meta-analysis showed that the total effective rate of the small needle knife group was significantly higher than that of the control group,OR=9.07,95%CI[4.64,17.76],Z=6.44,P<0.00001 and the cure rate of the small needle knife group was significantly higher than that of the control group,OR=7.86,95% CI[5.75,10.74],Z=12.93,P<0.00001. Conclusion:The curative effect of small needle knife therapy was better than that of the control group. Since the study included a limited number of trials and the quality of the literature was not high,the funnel plot showed publication bias,so the conclu-sion need to be validated by more rigorous randomized controlled trials.
