I Isingeniso
I-prosthesis yamadolo iqukethe i-condyle ye-femoral, inaliti ye-tibial marrow, inaliti yomnkantsha wesifazane, ingxenye ye-truncated kanye ne-wedges yokulungisa, i-shaft medial, i-tee, ithreyi ye-tibial plateau, umvikeli we-condylar, i-tibial plateau insert, i-liner, kanye nezingxenye zokuvimbela.
II Izici zomkhiqizo we-prosthesis yamadolo
Ukwamukela umklamo womuntu siqu, umklamo we-bionic wendawo ehlangene ungakha kabusha umsebenzi ovamile wamadolo;
Izakhiwo ze-biomechanical kanye ne-elastic modulus ye-3D ephrintiwe i-bone trabecular interface ihambisana kakhulu nomzimba womuntu, futhi izakhiwo zemishini zingcono;
Isakhiwo se-mesh esinezimbotshana siyaxhumana ukuze sakhe ukwakheka kwekhekheba lezinyosi lethambo elikhanseliwe nokuvumelana okuhle kwe-titanium alloy, okwenza ithambo likhule ngokushesha nangokuvikelekile.

III Izinzuzo ze-prosthesis yamadolo
I-1.Ukusebenza okuhle kakhulu kokukhula kwethambo nezicubu ezithambile kanye nokufakwa
Umfanekiso 1 Ukukhula kwethambo ezilwaneni ezinezakhiwo ze-trabecular zamathambo
I-porosity yalo mkhiqizo igcinwa ngaphezu kwe-50%, ehlinzeka isikhala esanele sokushintshaniswa kwezakhi kanye ne-oksijeni, ikhuthaza ukwanda kwamangqamuzana kanye ne-vascularisation yamangqamuzana e-stem, futhi ifinyelele izicubu ingrowth. Izicubu ezisanda kuzalwa zikhula zingene embotsheni ye-prosthesis surface futhi zihlangane zibe yinetha engafani, ehlanganiswe ngokuqinile nongqimba olungaphezulu lwentambo ye-titanium ekujuleni okungaba ngu-6 mm. Ezinyangeni ezi-3 ngemuva kokuhlinzwa, izicubu zikhula zibe yi-matrix futhi zigcwalise yonke indawo yesakhiwo se-porous, ngokujula okungaba ngu-10 mm, futhi izinyanga ezingu-6 ngemva kokuhlinzwa, izicubu ze-tendon ezivuthiwe zikhula zibe yisakhiwo sonke se-porous, ngenani elibaluleke nakakhulu lokugcwalisa.
2.Izakhiwo ezinhle zokukhathala
Umfanekiso 2 Imiphumela yokuhlolwa kokukhathala kwethreyi ye-tibial plateau
Ipuleti ye-tibial yahlolwa ngomshini ngokusho kwe-ASTM F3334 futhi yabonisa ukusebenza kahle kokukhathala ngemijikelezo ye-10,000,000 yokuhlolwa kokukhathala ngaphansi kwezimo zokulayisha ze-sinusoidal ze-90N-900N ngaphandle kokuqhekeka.
3.Ukumelana nokugqwala okuhle kakhulu
Fig. 3 Ukuhlolwa kokugqwala kwe-Micromotor endaweni ye-femoral condyle kanye ne-medullary inaliti yokuhlangana
Ngokusho kwe-YY/T 0809.4-2018 ukulayisha okujwayelekile kwe-cyclic futhi akukho ukwehluleka okutholakalayo, imiphumela ibonisa ukuthi lo mkhiqizo unokusebenza okuhle kakhulu kwe-anti-cone micro-motion corrosion, ukuze kuqinisekiswe ukuphepha kokuhlangana kwamadolo ngemva kokufakwa emzimbeni womuntu.
4.Ukumelana nokugqoka okuhle kakhulu
Umfanekiso 4 Isithombe semiphumela yokuhlolwa yokuhlolwa kwezingubo zokwenziwa kwamadolo
Ngokwe-ISO 14243-3: I-2014 ejwayelekile yokuhlolwa kokuhlolwa kokugqoka okuhlangene kwamadolo, imiphumela ibonisa ukuthi umkhiqizo unokuphikiswa okuhle kakhulu kokugqoka, ukuqinisekisa ukuphepha kokuhlangana kwamadolo ngemva kokufakwa emzimbeni womuntu.
