Abstract:
Objective:To investigate the epidemiological status of knee joint tuberculous arthritis in 52 patients and to identify risk factors for recurrence after treatment.Methods:A retrospective analysis was conducted involving 52 patients with knee joint tuberculous arthritis who received treatment at Shaanxi Provincial Tuberculosis Prevention and Control Hospital from January 2018 to June 2023. Patients concurrently diagnosed with knee joint tuberculous arthritis were identified from the hospital's records, and their clinical data were collected. Logistic regression analysis was performed to determine the risk factors associated with recurrence of knee joint tuberculous arthritis.Results:The incidence of knee joint tuberculous arthritis is higher in males than in females, with the most affected age group being 40-60 years old. The most common form of the disease is total knee joint tuberculosis. The positive rate of Mycobacterium tuberculosis culture is 100%, indicating high diagnostic value. Logistic regression analysis results show that the following are independent risk factors for recurrence of knee joint tuberculous arthritis: age > 45 years ( OR = 3.080, 95% CI: 1.445-6.564, P = 0.004), body mass index < 18.5 kg/m2 ( OR = 6.062, 95% CI: 1.621-22.671, P = 0.007), smoking ( OR = 2.649, 95% CI: 1.032-6.799, P = 0.043), diabetes ( OR = 3.629, 95% CI: 1.799-7.321, P = 0.007), duration of tuberculosis symptoms > 6 months ( OR = 5.507, 95% CI: 1.210-25.055, P = 0.027), non-compliance with anti-tuberculosis medication ( OR = 3.152, 95% CI: 1.149-8.649, P = 0.026), elevated erythrocyte sedimentation rate ( OR = 3.297, 95% CI: 1.223-8.889, P = 0.018), and elevated C-reactive protein ( OR = 2.519, 95% CI: 1.025-6.194, P = 0.044). Conclusions:Knee joint tuberculous arthritis is more prevalent in males, with the most affected age group being 40-60 years old. Clinically, a comprehensive diagnosis that includes clinical evaluation, imaging, and bacterial culture is necessary. Lesion excision surgery can result in a good prognosis. Independent risk factors for the recurrence of knee joint tuberculous arthritis include age > 45 years, body mass index < 18.5 kg/m2, smoking, diabetes, duration of tuberculosis symptoms > 6 months, non-compliance with anti-tuberculosis medication, elevated serum erythrocyte sedimentation rate, and elevated C-reactive protein.
