什么是骨性关节炎骨关节炎是一种发生在滑膜关节、发展缓慢，以局部关节软骨破坏，并伴有相邻软骨下骨板骨质增生或骨唇形成为特征，由机械性、代谢、炎症和免疫等因素作用而造成的关节疾病。病理特点病理特点为关节软骨变性破坏、软骨下骨硬化或囊性变、关节边缘骨质增生、滑膜增生、关节囊挛缩、韧带松弛或挛缩、肌肉萎缩无力等。临床表现1、关节疼痛及压痛初期为轻度或中度间断性隐痛，休息时好转，活动后加重，疼痛常与天气变化有关。晚期可出现持续性疼痛或夜间痛。关节局部有压痛，在伴有关节肿胀时尤为明显。2、关节僵硬在早晨起床时关节僵硬及发紧感，也称之晨僵，活动后可缓解。关节僵硬在气压降低或空气湿度增加时加重，持续时间一般较短，常为几分钟至十几分钟，很少超过30分钟。3、关节肿大手部关节肿大变形明显，部分膝关节因骨赘形成或关节积液也会造成关节肿大。4、骨摩擦音(感)由于关节软骨破坏、关节面不平，关节活动时出现骨摩擦音(感)，多见于膝关节。5、关节无力、活动障碍关节疼痛、活动度下降、肌肉萎缩、软组织挛缩可引起关节无力，行走时软腿或关节绞锁，不能完全伸直或活动障碍。辅助检查OA的X线表现可有：关节间歇狭窄、关节软骨下骨质硬化、边缘骨质增生、关节鼠形成及软骨下囊性变。Work-uptakelongfilmsofbothlowerlimbs(standing,patellaefacingforward,feettogether)traceallpreviousX-raysandfindthepreviousoperationrecords(forrevisioncases)considerkneeaspirationandbone(Indium111)scanifsepsisissuspected(forrevisioncases)术前准备拍摄双侧下肢全长X光片(站立位、髌骨向前、双足并拢)回顾所有以前拍摄过的X光片并找出以往手术记录(对于翻修病例)如果怀疑感染﹐可考虑行膝关节穿刺和铟111同位素骨扫描(对于翻修病例)Pre-operative(medical)fillinthetotalkneereplacementarthroplastydocumentationformconfirmthepresenceofallprosthesesandspecialinstrumentsthatmaybeneededwithOTstaffmakesurethatallograftisavailableifthatispartofthesurgicalplan术前准备(医生)填写全膝关节置换术记录表与手术室同事确认所需的假体和特殊器械均已到位手术方案中若需植骨﹐则事先确认有合适的异体骨可供选用Pre-operative(therapists)baselineassessmentbyphysiotherapist&occupationaltherapistassessrange&quadricepspower,measurecircumferencesatkneejoint,10cm.aboveitand10cm.belowitteachpost-op.exercisese.g.activekneemobilization,staticquadriceps,straight-leg-raising,bridging术前准备(治疗师)由物理治疗师和职业治疗师进行基本状况评估膝关节活动范围及股四头肌肌力评估﹐在距离膝关节上下各10厘米处测量大腿及小腿的周径指导术后的操练﹐例如膝关节的主动活动﹐股四头肌静力收缩﹐直腿高举以及伸腰弯弓动作的练习Operativesupineposition,applyfootpositionerbeforedraping(sothatthekneecanbelockedinfullflexion)thightourniquetisappliedbutisonlyinflatedafterdraping(tourniquetonlyusedforcementationafter2001)nobulkingdrapearoundfootandanklesurgicalapproach(Insall)withperiosteumelevatedfrommedialthirdofthepatellaisadoptedpatellaisreplacedroutinelyinrheumatoidarthritis,butnotosteoarthritisintramedullaryguideforfemoralcutsandextramedullaryguidefortibialcutscutsurfacesarecleansedwithpulsatilelavagesystembeforecementation(noneedforcementlessfixation)allthreecomponentsareinsertedwithonepackofEndurancecementmixedinpartialvacuum;ifexposureissub-optimal,cementthepatellarbuttonandtibialtrayfirst,andtheninsertthefemoralcomponentwithanotherpackofcement(cementgunafter2001)tourniquetisdeflatedafterallcomponentsareinsertedandbeforewoundclosureforhemostasisbulkingdressingisappliedafterwardsforbilateralinvolvementwithsimilarseverity,bothkneeswillbereplacedunderthesameanaesthesia,oneaftertheother-“one-stag...
