论著老年糖尿病合并膝关节骨性关节炎行单髁置换术后胫骨后倾角变化对患者关节活动功能的影响胡书华赵阳李杰(南阳市中心医院住院管理处,河南南阳４７３０００)[摘要]【目的】探讨老年糖尿病合并膝关节骨性关节炎行单髁置换术(UKA)后胫骨后倾角(posteriortibialslope,PTS)变化对患者关节活动功能的影响.【方法】回顾性分析２０２０年６月至２０２２年６月在本院接受UKA的９６例老年糖尿病合并膝关节骨性关节炎患者的临床资料,计算手术前后PTS的变化值(△PTS),根据△PTS分为PTS减小组(△PTS＜－２．５°,n＝３６)和PTS微减组(－２．５°≤△PTS＜０°,n＝４２)及PTS增大组(△PTS≥０°,n＝１８).所有患者术后均至少随访１２个月,比较各组患者术后膝关节活动度(rangeofmotion,ROM)、膝关节主动活动时所能达到的最大屈曲角度(maxflexiondegree,MFD)、膝关节协会临床评分(KneeSocietyClinicalScore,KSSＧC)、膝关节协会功能评分(KneeSocietyFunctionalScore,KSSＧF),并记录术后并发症的发生情况;采用PearＧson相关性分析△PTS与术后ROM、MFD、KSSＧC、KSSＧF的相关性.【结果】PTS减小组患者术后ROM、MFD、KSSＧC、KSSＧF均高于PTS微减组及PTS增大组(P＜０．０５).△PTS与ROM、MFD、KSSＧC、KSSＧF呈负相关(P＜０．０５).各组患者术后并发症发生率比较,差异无统计学意义(P＞０．０５).【结论】对于老年糖尿病合并膝关节骨性关节炎患者,UKA术后PTS适当减小可显著改善患者膝关节功能,提高患者生活质量.[关键词]糖尿病;骨关节炎,膝/外科学;胫骨/生理学;老年人TheInfluenceoftheChangesofTibialPosteriorInclinationontheJointFunctionofElderlyPatientswithDiabetesComplicatedwithKneeOsteoarthritisafterUnilateralCondylarReplacementHUShuhua,ZHAOYang,LIJie(InpatientManagementOffice,NanyangCentralHospital,HenanNanyang４７３０００)[Abstract]【Objective】Toinvestigatetheeffectofthechangeoftibialposteriorslope(PTS)afterunilateralcondylararthroplasty(UKA)inelderlypatientswithdiabetescombinedwithkneeosteoarthritisonjointactivity．【Methods】Theclinicaldataof９６elderlypatientswithdiabetescombinedwithkneeosteoarthritiswhoreceivedUKAinourhospitalfromJune２０２０toJune２０２２wereretrospectivelyanalyzed,andthechangevalueofPTS(△PTS)beforeandaftersurgerywascalculated．Accordingto△PTS,theyweredividedintoPT...
