TKA Prosthesis- LDK X4 Primary Total Knee Arthroplasty
1.
O le condyle pito i luma o le femoral prosthesis o loʻo tuʻuina atu i le faʻaitiitia o le lautele ma le mafiafia e faʻaitiitia ai le mamafa o le condyloid i luma ma le faʻalavelave quadriceps.O le sagittal geometry tutusa ma le lamolemole lamolemole e mafai ai e le patella ona le faʻateleina le malosi o le quadriceps femoris pe a faʻalautele le tulivae ma faʻafefe.I le tuʻufaʻatasia ma le patellar trochlear groove, e mafai ona faʻamautinoa o loʻo mautu le patella ma i totonu o le tootoo e oʻo lava i le maualuga o le flexion e aunoa ma se faʻalavelave, ma le faʻafesoʻotaʻi tumau i le va o le patella ma le femoral prosthesis e tausia i taimi uma.
2.
O le femoral prosthesis ua mamanuina i se va'alele fa'alu'u teisi e fa'atele le vaega fa'afeso'ota'i ina ia fa'aitiitia ai le maualuga o le mamafa i luga o le polyethylene fa'aofi.O le faʻamaufaʻailoga mataʻitusi e faʻaumatia i le taimi o le varus-valgus rotation o le tulivae, ina ia tumau pea le faʻafesoʻotaʻi o le tibiofemoral i taimi uma faʻafeiloaʻi faʻasaga.
3.
O le pito i luma o le patellar notch o le polyethylene insert e faʻaitiitia ai le faʻaopoopoga o le mamafa ma le vevesi i luga o le quadriceps femoris i le taimi maualuga.
4.
Ua faateleina le pupuni o le condylar i tua.O le tibiofemoral articular surface e tumau pea le faʻafesoʻotaʻi i luga ae le o le faʻafesoʻotaʻi pe a oʻo i le 135 tikeri.
5.
Open intercondylar fossa design: O le intercondylar osteotomy ua faʻaitiitia, ma o le ponaivi e faʻasaoina i le tulaga sili mo le maʻi.
6.
Faʻatonuina le faʻaogaina o le cam-post: O loʻo tumau pea le cam i le pito i lalo o le koluma aʻo maualuga le tulivae, e puipuia ai le tupu mai o le faʻamaʻi o le tino i le taimi o le faʻafefe maualuga i se tulaga faʻatapulaʻa.
7.
O lo'o tu'uina atu se masini fa'apipi'i fa'apipi'i tulaga ese.O le fa'apipi'i lona lua ma taula u'amea e mafai ona fa'aumatia ai le fa'alavelave fa'alavelave i le va o le lua.
8.
O le fausaga o le tolu-apa'au e taofia ai le feliuliua'i ma aloese mai le fa'alavelave mamafa.
