目的：探讨膝骨性关节炎初次人工膝关节表面置换的治疗时机。方法根据Kelgren-Lawrence X线骨关节炎分级和Outerbridge软骨损伤分级，采用多重线性回归分析方法，对21例（23膝）重度膝骨关节炎患者实施初次人工膝关节表面置换术，统计分析自变量因素和手术效果之间的线性依存关系。结果本组病例术后疼痛和功能障碍均改善，平均随访（11.2±1.5）个月，根据HSS评分，优16膝；良3膝；可4膝。多重线性回归方程的假设检验具有统计学意义。结论选择重度膝骨关节炎和非人工膝关节置换治疗无效患者实施初次人工膝关节表面置换能提高疗效，但该手术治疗存在一定程度的风险和未知疗效影响因素。

Objective To explore the first artificial knee osteoarthritis knee joint surface replacement treatment time.MethodsAccording to the Kelgren - Lawrence X-ray osteoarthritis classification and grading Outerbridge cartilage injury, using multiple linear regression analysis method in 21 patients (23) of severe knee osteoarthritis patients primary artificial knee arthroplasty, statistical analysis of the independent variable factors and linear dependencerelation between the effect of surgery.ResultsThe incidence of postoperative pain and dysfunction were significantly improved, an average folow-up of 11.2 + / - 1.5 months, according to the HSS score, optimal 16 knees; Good 3 knee; 4 knees. Multiple linear regression equation of hypothesis test of statistical significance.Conclusion Severe knee osteoarthritis and implementation of the first patients without artificial knee joint replacement therapy and artificial knee joint surface displacement can significantly improve curative effect, but the surgery has certain curative effect degrees of risk and unknown factors.
