目的：探讨院外延伸护理对人工全膝关节置换患者功能恢复和生活质量的影响。方法将89例单侧初次人工全膝关节置换患者按入院时间分为干预组和对照组。干预组45例，男性19例，女性26例；平均年龄（64.91±8.99）岁；对照组44例，男性16例，女性28例；平均年龄（65.66±7.24）岁。两组患者在住院期间均给予常规护理；出院后对照组不予延伸护理，干预组电话随访1次／周，门诊随访1次／2周，3个月后视患者的康复情况酌情增减随访次数，随访时间为1年。两组患者均于术后1、3、6、12个月分别采用美国特种外科医院膝关节评分（ HSS）及SF-36量表测评。结果两组患者在术后1、3、6、12个月时：SF－36量表测评、膝关节评分干预组均显著优于对照组（ P＜0.01）。结论院外延伸护理有利于人工膝关节置换术后膝关节功能的恢复，提高了治疗效果及患者对护理质量的满意度。%Objective To investigate the effect of extended care on functional recovery and quality of life for total knee arthroplasty patients . Methods Totally 89 patients with unilateral primary total knee arthroplasty were randomly divided into intervention group and control group according to admission time .
