Clinical study of minimally invasive needle knife treatment of chronic knee periarthritis
Abstract：Objective To observe the clinical therapeutic effect of minimally invasive needle knife treatment of chronic knee periarthritis.Methods By semi-randomized method,200 cases of chronic knee periarthritis were di-vided into observation group and control group, 100 cases in each group.The observation group received needle knife minimally invasive lysis treatment after nerve block, while the control group only received the treatment of nerve block.Before treatment and at 1 w, 2 w and 4 w after treatment resting pain VAS score( rest visual analogue scale, RVAS) and the passive activity VAS score( passive visual analogue scale,PVAS) were compared between the two groups;and the comprehensive curative effect was compared between the two groups.Results After treatment, RVAS score and PVAS score in the two groups decreased, and the overall score of the observation group was lower than that of the control group, with significant difference(P<0.05).Compared with the control group, pain RVAS score and PVAS score at 2 w and 4 w in the observation group were significantly decreased after treatment ( P<0.05 ) .The therapeutic effect of observation group was better than that of the control group(P<0.01).Conclusion The mini-mally invasive needle knife treatment has a significant efficacy in the treatment of chronic knee periarthritis,and its long-term efficacy is superior to single nerve block treatment.
