Correlation Between Primary Knee Osteoarthritis And TCM Constitution Type Distribution

Purpose: Observe the distribution of TCM constitution types of knee osteoarthritis(Knee Osteoarthritis,KOA),study the differences and connections between constitution and symptoms and signs,and provide guidance for the early prevention and treatment of KOA for patients with different constitutions under the guidance of the concept of "treating the disease.Method: Collect the KOA patients who visited in Chengdu,Nanchong,Mianyang,Yibin,Meishan,Luzhou and other places from October 2018 to October 2019 as the research object,and record demographic data,physical type,VAS,joint activity,swelling,muscle strength,WOMAC,etc.,establish a database,and draw conclusions through data analysis.Result:1.General situation: A total of 1070 cases were collected,including 238 males(22.2%)and 832 females(77.8%).50-65 years old accounted for 44.3%,60-79 years old accounted for 36.3%,80-99 years old accounted for 19.4%.There was a significant difference between gender and age,P <0.001.2.Distribution of constitution types: Yang deficiency 20.8% > Sputum dampness 15.8% Yin deficiency 12.7% > Peace quality 11.6% > Hydration 11.3% > Damp heat quality 10.2% > Qi deficiency 9.1% > Qi 5.4% > Trait 3.1%.Damp-heat,phlegm,and qi deficiency are the main factors in men;yang deficiency,phlegm,and blood stasis are the main factors in women;,Phlegm dampness,damp heat quality,80-99 years old are mainly peace,blood stasis,phlegm dampness quality.There was a difference between physical fitness,gender,and age,all P <0.001.3.Constitution and BMI: There is a difference between constitution and BMI,both P <0.001.The overweight patients are mainly of phlegm dampness,yang deficiency,and yin deficiency,and the obese patients are mainly of yin deficiency,blood stasis,and damp heat.4.Constitution and VAS: There are differences between constitution and VAS,both P <0.001.The most significant effects on VAS were yang deficiency,yin deficiency,phlegm dampness,and blood stasis.5.Physical fitness and joint mobility: There is a difference between physical fitness and joint mobility.P in one knee and both knees is <0.001.The most important effects on joint mobility are yang deficiency,phlegm dampness,and blood stasis.6.Physical and joint swelling: There is a difference between physical and swelling.P in one knee and both knees is less than 0.001.The biggest influence on swelling is yang deficiency and blood stasis.7.Physical fitness and muscle strength: There is a difference between physical fitness and muscle strength,with P of each knee and both knees <0.001.The biggest influence on muscle strength is blood stasis,phlegm,and peace.8.Physical fitness and WOMAC: There is a difference between physical fitness and WOMAC.P in one knee and both knees are both <0.001.The biggest influence on WOMAC is yang deficiency,phlegm dampness,and yin deficiency.Conclusion: There were differences in the distribution of constitution types and related factors in KOA patients,and the differences were statistically significant.Yang deficiency,phlegm dampness,and yin deficiency are susceptible to KOA.There are differences between physical type and BMI,VAS,joint mobility,swelling,muscle strength,and WOMAC,indicating that physical affects the incidence of KOA.
