Abstract:
Objective:To explore the relationship between the expression of inflammatory factors and the degree of pain in patients with Kashin-Beck disease after total knee arthroplasty.
Methods:Forty-nine patients with Kashin-Beck disease and 55 patients with knee osteoarthritis who underwent total knee arthroplasty in the Department of Orthopaedics, Gansu Provincial People's Hospital from January 2016 to December 2018, were selected, as the Kashin-Beck disease group and osteoarthritis group, respectively, and 50 healthy subjects who underwent healthy physical examination at the same time were selected as the control group. At the 7th day after operation, 3 ml of fasting venous blood was collected from all subjects. The expression levels of interleukin (IL)-6, tumor necrosis factor (TNF)-α, and C-reactive protein (CRP) were measured by enzyme-linked immunosorbent assay (ELISA); the visual analogue score (VAS) and knee society score (KSS) were used to compare the pain degree and knee function of each group; correlation analysis between postoperative inflammatory factor levels and VAS, KSS scores in patients with Kashin-Beck disease were studied.
Results:The expressions of IL-6 [(78.17 ± 13.28), (60.28 ± 9.92), (9.65 ± 3.12) ng/L], TNF-α [(126.67 ± 15.83), (105.29 ± 12.76), (21.09 ± 5.82) ng/L] and CRP [(11.23 ± 3.41), (8.31 ± 2.54), (2.14 ± 1.01) mg/L] in Kashin-Beck disease group, osteoarthritis group and control group were significantly different (F=12.397, 19.982, 9.167, P < 0.05); and the VAS scores [(5.21 ± 1.44), (2.98 ± 1.03), (0.61 ± 0.22) points], and KSS scores [(60.15 ± 8.91), (72.91 ± 9.19), (93.92 ± 5.73) points] between the three groups were statistically different (F=21.092, 16.743, P < 0.05). The correlation analysis showed that IL-6, TNF-α, and CRP levels were positively correlated with VAS scores in patients with Kashin-Beck disease (r=0.517, 0.498, 0.522, P < 0.05), and negatively correlated with KSS scores (r=-0.509,-0.514, -0.487, P < 0.05).
Conclusion:After total knee arthroplasty for patients with Kashin-Beck disease, the expression levels of inflammatory factors IL-6, TNF-α and CRP are higher, and they are associated with postoperative pain and knee function recovery.
