摘要
目的进行全膝关节置换术(TKA)后膝关节功能康复个体化列线图预测模型的建立与验证。方法选取2019年1月至2021年12月复旦大学附属上海市第五人民医院接收的150例膝骨关节炎病人为建模组。选取2020年1月至2021年12月该院接收的102例膝骨关节炎病人为验证组。将建模组病人分为康复不理想组(n=72)和康复理想组(n=78)。对建模组病人采用logistic回归法筛选影响TKA后膝关节功能康复不理想的危险因素;采用R软件构建预测TKA后膝关节功能康复不理想的列线图模型;用受试者操作特征(ROC)曲线评价模型区分度,校准曲线评估列线图模型一致性。结果康复不理想组年龄≥65岁比例58.33%(42/72)、糖尿病比例41.67%(30/72)、未有软组织平衡术比例63.89%(46/72)、术后胫骨平台后倾角≥5°比例45.83%(33/72)、术前HSS评分<45分比例56.94%(41/72)、术后VAS评分≥6分比例62.50%(45/72)高于康复理想组[28.21%(22/78)、19.23%(15/78)、32.05%(25/78)、23.08%(18/78)、26.92%(21/78)、32.05%(25/78)](P<0.05)。logistic回归分析显示,年龄≥65岁、未有软组织平衡术、术后胫骨平台后倾角≥5°、术前HSS评分<45分、术后VAS评分≥6分是TKA后膝关节功能康复不理想危险因素(P<0.05)。基于危险因素用R软件建立列线图模型,建模组曲线下面积(AUC)及其95%CI为0.88(0.82,0.93),验证组AUC及其95%CI为0.89(0.82,0.95),列线图模型的区分度良好,列线图模型的校准曲线预测值与实际值基本一致,Hosmer-Lemeshow拟合优度检验显示,建模组χ^(2)=7.36,P=0.499;验证组χ^(2)=7.13,P=0.415。结论构建的预测TKA后膝关节功能康复不理想列线图模型具有较大临床价值,可指导个体化治疗。
Objective To establish and verify an individualized nomogram prediction model for knee joint functional recovery after total knee arthroplasty(TKA).Methods A total of 150 patients with knee osteoarthritis who received treatment at Shanghai Fifth People's Hospital affiliated to Fudan University from January 2019 to December 2021 were selected as the modeling group.The 102 patients with knee osteoarthritis who received in this hospital from January 2020 to December 2021 were selected as the validation group.The patients in the modeling group were divided into a poor recovery group(n=72)and an ideal recovery group(n=78).A logistic regression method was used to screen the risk factors affecting poor knee joint functional recovery after TKA in the modeling group.R software was used to construct a nomogram model for predicting poor functional recovery of knee joint after TKA.A receiver operating characteristic(ROC)curve was used to evaluate the model discrimination,and the calibration curve was used to evaluate the nomogram model consistency.Results The proportion of age≥65 years in the poor recovery group was 58.33%(42/72),the proportion of diabetes was 41.67%(30/72),the proportion of nonsoft tissue balance was 63.89%(46/72),the proportion of postoperative tibial plateau posterior inclination angle≥5°was 45.83%(33/72),the proportion of preoperative HSS score<45 points was 56.94%(41/72),and the proportion of postoperative VAS score≥6 was 62.50%(45/72)higher than those in the ideal recovery group[28.21%(22/78),19.23%(15/78),32.05%(25/78),23.08%(18/78),26.92%(21/78),and 32.05%(25/78)](P<0.05).Logistic regression analysis showed that age≥65 years,nonsoft tissue balance surgery,postoperative tibial plateau posterior inclination≥5°,preoperative HSS score<45,and postoperative VAS score≥6 were risk factors for poor functional recovery of the knee joint after TKA(P<0.05).Based on the risk factors,a nomogram model was established with R software,and the area under the curve(AUC)of the modeling group was 0.88[95%CI:(0.82,0.93)],and the area under the ROC curve of the validation group was 0.89[95%CI:(0.82,0.95)],the discrimination of the nomogram model was good,the predicted value of calibration curve of the nomogram model was basically consistent with the actual value,and the Hosmer‒Lemeshow goodness-of-fit test showed that the modeling group χ^(2)=7.36,P=0.499;validation group χ^(2)=7.13,P=0.415.Conclusion The constructed nomogram model for predicting poor knee joint functional recovery after TKA has great clinical value and can guide individualized treatment.
