Observe The Clinical Effect Of Blood-letting By Collateral Puncture In The Treatment Of Knee Osteoarthritis Based On Musculoskeletal Ultrasound

Objective:Through musculoskeletal ultrasonography and scale,the effect and clinical effect of "blood change pathogenic removing" collature-pricking and blood-letting therapy on knee osteoarthritis(KOA)with blood stasis under the guidance of "taking general use as the guideline" were observed.Methods:Seventy-four patients with blood stasis type KOA who met the inclusion criteria were randomly divided into experimental group(basic treatment + "blood change pathogenic removing" collateral pricking and bloodlet therapy)and control group(basic treatment + oral celecoxib capsule),37 cases in each group.Two weeks was a course of treatment,and two courses of treatment were given to both groups.Before and after treatment,musculoskeletal ultrasound measurements(knee suprapellar sac effusion depth,synovial thickness),knee joint range of motion(KROM)measurement results,visual analog scale of knee tenderness(VAS),WOMAC Osteoarthritis index score were collected,and the data were imported into SPSS23.0 software for data analysis.Results:1.Baseline comparison: A total of 66 cases were included,33 cases in each group.After software statistics,the two groups had the same baseline before treatment and were comparable.2.Therapeutic results:(1)Efficacy evaluation results: after treatment,the total effective rate of the experimental group was 93.94%,and that of the control group was 84.85%,and the efficacy of the experimental group was better than that of the control group(P<0.05).(2)Measurement results of the effusion depth of suprapellar sac of knee joint:The effusion depth of suprapatellar bursa in experimental group was significantly lower than that in control group(P<0.01),The effusion depth after treatment in both groups was significantly lower than that before treatment(P<0.01).(3)The results of synovial thickness measurement of knee joint: after treatment,the synovial thickness of experimental group was significantly lower than that of control group(P<0.01),After treatment,the synovial thickness in both groups was significantly lower than before(P<0.01).(4)Visual analogue score of knee tenderness(VAS)results: VAS score of experimental group after treatment was lower than that of control group(P<0.05),and VAS score of both groups after treatment was significantly lower than that before treatment(P<0.01).(5)Knee motion(KROM)measurement results: After treatment,KROM in 2 groups was significantly higher than that before treatment(P<0.01),and there was no statistical difference in KROM between 2 groups after treatment(P>0.05).(6)WOMAC Osteoarthritis Index total score: The total score of the experimental group after treatment was significantly lower than that of the control group(P<0.01),and the total score of the two groups after treatment was significantly lower than that before treatment(P<0.01).(7)scores of daily living ability between the two groups(P>0.05).The score of pain item in experimental group was lower than that in control group(P<0.05).The score of stiffness item in experimental group was significantly lower than that in control group(P<0.01);Within the two groups,scores of each item after treatment were significantly lower than those before treatment(P<0.01).Conclusion:1.Under the guidance of "taking general use as the guideline",bloodletting therapy can not only reduce the pain and stiffness of knee joint,but also improve the knee joint effusion and synovial hyperplasia,and the effect is better than oral celecoxib capsule.2."blood change pathogenic removing" collateral pricking and bloodletting therapy is helpful to improve patients’ knee joint mobility and daily living ability,and the therapeutic effect is equivalent to that of oral celecoxib capsule.
