Ungakhetha kanjani i-prosthesis yamadolo?

Ijoyinti ledolo lokwenziwaYakhiwe yingxenye ye-femur, ingxenye ye-tibia kanye ne-patella, engalingisa ukusebenza kwejoyinti ledolo lomuntu futhi ithathe indawo yamalunga agulayo noma alimele.

Indlela yokukhetha i-i-prosthesis yamadolo?
Njengamanje, i-knee arthroplasty ingahlukaniswa ibe yi-partial knee arthroplasty (i-unicompartmental knee arthroplasty) kanye ne-total knee arthroplasty (TKA)

I-Partial knee arthroplasty (i-unicompartmental arthroplasty)
Ukufakelwa Kwamadolo Okuyingxenyeiwukushintshwa kwangempela kwendawo ngaphandle kokulimala okuncane kokuhlinzwa, ukulondolozwa kwemisipha ye-cruciate yangaphambili nengemuva, ukululama okusheshayo kokusebenza kwamalunga ngemva kokuhlinzwa, ukusondela ekunyakazeni kwedolo okuvamile, kanye nokuhamba kahle kwamalunga nokuhamba kungatholakala. Ngezinzuzo nezinkomba ezihlukile, isebenza njengenye yezindlela zokwelapha ezikhethwayo zezilonda ezivalelwe engxenyeni eyodwa ye-tibiofemoral yedolo. Kodwa-ke, i-UKA inezinkomba ezimbalwa kanye nesilinganiso esiphakeme sokuxega kwe-tibial ngemuva kokuhlinzwa, okunciphisa ukusetshenziswa kwe-UKA ezimweni zemitholampilo.

Ukufakelwa Okuphelele Kwesinqe
Ukufakelwa Kwamadolo Okuphelelezisetshenziswa kakhulu ekuhlikihleni kwamadolo. Izinhlobo eziyinhloko ezisetshenziswa emtholampilo yilezi ezilandelayo:
I-prosthesis egcina i-Posterior Cruciate Lligament: Lokhuijoyinti ledolo lokufakelwaIncike kakhulu ku-posterior cruciate ligament yejoyinti, ukuze kuqinisekiswe ukuqina kwangemuva kwe-tibia. Inezinga eliphansi lokulingana kanye nokuvinjelwa okuncane. Ukucindezeleka okubangelwa ukunyakaza kwamalunga abantu kumuncwa yi-ligament, futhi ingcindezi ye-prosthesis incishiswa kakhulu. Ekuhlinzeni kwamalunga ngokulondolozwa kwe-posterior ligament, umthwalo engxenyeni yangemuva yejoyinti mkhulu kakhulu, okungase kwandise ukuguguleka kwe-polyethylene insert ye-prosthesis. Ngakho-ke, kusadingeka kufundwe kabanzi futhi kuthuthukiswe emtholampilo.

I-prosthesis engena-Ligament engemuva kwe-Cruciate: Umklamo walokhuidolo elihlangenei-prosthesisIgxile ekwandiseni izinga lokuzinza nokunciphisa ukucindezeleka lapho ithintana ne-prosthesis. Inezinga eliphezulu le-anastomosis futhi imvamisa inomklamo we-CAM. Izinzuzo zayo zifaka phakathi ukususwa kwe-posterior cruciate ligament, ihlinzeka ngokulinganisela nokuzinza kwemisebenzi yokugoba kanye nokwandisa; Ukwandisa ukugoba kwamalunga ngokwandisa isikhala sokugoba; I-prosthesis inokuqina okuphezulu futhi ifaneleka neziguli ezine-knee valgus kanye ne-flexion deformity. Ukungalungi kwayo kungokulandelayo: izinga eliphezulu le-gap anastomosis lenza ukucindezeleka kugxile nge-prosthesis, kwandisa umthwalo wesigaba se-femoral, futhi kunezinga eliphezulu lokuxega sekwephuzile kune-posterior cruciate ligament-preserving prosthesis. Inani lethambo elisusiwe ngokufakwa kwe-prosthesis likhulu kakhulu, okwenza ukuhlinzwa kokubuyekezwa kube nzima kakhulu. I-posterior cruciate ligament-free prosthesis inezinkomba eziningi, futhi inqubo ethile yokuhlinzwa ilula kakhulu. Luhlobo lwe-prosthesis olusetshenziswa kabanzi ekwelashweni kwezokwelapha njengamanje.

Uma ufuna ukufunda kabanzi mayelana ne-ki-neeai-rthroplastyiisitshaloulwazi, sicela ukhululekeXhumana nathi; ithimba lethu lizokunikeza ukwesekwa kochwepheshe kanye nezimpendulo.
