Abstract:
Objective To investigate the changes of serum sclerostin(SOST)and secreted frizzled related protein 5(SFRP5)levels and their prognostic value in patients with post-traumatic osteoarthritis(PTOA).Methods 84 patients with PTOA admitted to the hospital from January 2020 to January 2022 were selected as the disease group,and 84 healthy patients who underwent physical examination in the hospital during the same period were selected as the health group.Serum SOST and SFRP5 levels were detected in the diseased and healthy groups by enzyme-linked immunosorbent assay.The patients in the disease group were followed up for 1 year and the prognosis of PTOA patients was evaluated by Lysholm knee function score.Spearman correla-tion analysis was used to analyze the correlation between serum SOST,SFRP5 and Lysholm knee function score in PTOA patients.Multivariate Logistic regression was used to analyze the prognostic factors of PTOA patients.The predictive value of serum SOST and SFRP5 levels in poor prognosis of PTOA patients was ana-lyzed by receiver operating characteristic(ROC)curve.Results Compared with the healthy group,the serum SOST and SFRP5 levels in the disease group were significantly decreased,and the difference was statistically significant(P＜0.05).Spearman correlation analysis showed that serum SOST and SFRP5 levels were posi-tively correlated with Lysholm knee function score.Multivariate Logistic regression analysis showed that body mass index＞25 kg/m2,Kelgran-Lawrence grade Ⅲ/Ⅳ at admission and cartilage Outerbridge grade Ⅲ/Ⅳ at admission were independent risk factors for poor prognosis in PTOA patients(P＜0.05).Long-term exercise,SOST and SFRP5 levels were protective factors(P＜0.05).ROC curve analysis showed that the area under ROC curve(AUC)of serum SOST and SFRP5 combined in predicting poor prognosis of PTOA patients was higher than that of SOST and SFRP5 alone in predicting poor prognosis of PTOA patients(Z=2.316,P=0.021;Z=2.356,P=0.019).Conclusion Serum SOST and SFRP5 levels are reduced in PTOA patients compared to healthy individuals,both of which are associated with poor prognosis in PTOA patients and have some predictive efficacy for patient prognosis.
