Objective To study the value of ultrasound in diagnosing knee osteoarthritis (KOA)in the alpine and high-altitude areas of Milin and screen its relevant influencing factors.Methods Clinical and ultrasonograph-ic examinations were performed from March to May 2022 on people with knee discomfort within Milin County.Results A total of 608 subjects were enrolled,including 200 males and 408 females;their mean age was (57.86±11.36)years,disease duration was 7 days-42 years,and median disease duration was 4 years.A total of 1216 knees were included,of which 971 were diagnosed,including 31.62％ male and 68.38％ female;of which 486 were left-sided,485 right-sided and 478 bilateral.The differences between age groups were statistical-ly significant.The sensitivity of ultrasound diagnosis of KOA was 0.93,the specificity was 0.36,the positive predictive value was 0.85,and the negative predictive value was 0.57.There were statistically significant differ-ences in postural and alcohol consumption between groups with and without KOA;there were no statistically sig-nificant differences in BMI between the KOA groups;and there were no statistically significant differences in smoking and diet between groups with and without KOA.Conclusion Ultrasound is highly sensitive to knee osteo-arthritis in the alpine and high altitude region of Milin;posture and alcohol consumption were associated with the development of this disease,while BMI,smoking and diet were not clearly associated.
