Analysis based on MOAKS scoring system for related factors affecting the prognosis of knee osteoarthritis-related pain treated with joint lavage
Objective:To evaluate the clinical efficacy of joint lavage(JL)in the treatment of knee osteoar-thritis(KOA)-related pain,and to analyze the factors affecting the prognosis after JL treatment,based on knee joint MOAKS scoring system and clinical features.Methods:Clinical data of KOA patients who received JL treatment in the Pain Department of Shandong Provincial Hospital from April 2019 to May 2022 were collected.The patients'numerical rating scale(NRS),Western Ontario and McMaster osteoarthritis index(WOMAC)pain subscale,analgesic medication usage and adverse events were retrospectively analyzed.The MRI imaging data of knee joint were evaluated by MOAKS scoring system.Multivariate Logistic regression and ROC curve were used to analyze the risk factors affecting the efficacy of JL.Results:A total of 82 patients were finally enrolled in this study.The NRS scores at discharge,1 month,3 months,and 6 months after JL treatment were significantly lower than before treatment(P<0.001).At 6 months after treatment,the WOMAC pain score and analgesic medication usage rate significantly decreased compared with before treatment(P<0.001).52 patients(62.2%)showed a decrease of≥50%in NRS scores at 6 months after JL.Multivariate binary logistic regression analysis revealed that duration of pain(OR = 1.022,95%CI:1.003-1.042,P = 0.024),bone marrow lesion score(OR = 1.221,95%CI:1.028-1.450,P = 0.023),and cartilage loss score(OR = 1.272,95%CI:1.021-1.585,P = 0.032)were independent risk factors affecting the prognosis after JL.Conclusion:JL treatment can significantly alle-viate pain of patients with KOA.The long duration of pain,severe bone marrow lesion and cartilage loss were independent risk factors for the unsatisfied pain relief after JL.
