国外塑料人工关节的应用与研究动态(续)Inrecentyears,theapplicationandresearchofplasticartificialjointsinforeigncountrieshavemadesignificantprogress,andhavebeenwidelyusedinthefieldofjointreplacementsurgery.Thematerialsusedinplasticartificialjointshavegraduallyevolvedfrompolyethylenetohighlycross-linkedpolyethylene,whichhasgreatlyimprovedthedurabilityandwearresistanceofthejointimplants.

Oneofthemainadvantagesofplasticartificialjointsisthattheyarelesslikelytocauseimmunereactionsandinfectionscomparedtometalorceramicmaterials.Thisisbecauseplasticmaterialsarechemicallyinertanddonotcorrodeorreleaseanyharmfulsubstancesintothebody.Inaddition,plasticartificialjointshavebettershockabsorptionandprovidemorenaturalmovement,whichcangreatlyimprovepatientcomfortandqualityoflife.
