Ngenhlanhla, ukuhlinzwa ngokuguqulwa kwamadolo, inqubo ethatha indawo ehlanganisiwe ne-metal kanye ne- plastic joint , iphumelela kakhulu ekunciphiseni ubuhlungu nokusebenza ngcono.
Kodwa-ke, abantu abaningi abane- arthritis kuphela emadolweni bakhathazekile ngokufaka endaweni yonke. Kukhona enye inketho kubantu abanesifo samathambo abalinganiselwe kuphela ingxenye yamadolo ahlangene , futhi lokho kubizwa ngokuthi ukuguqulwa kwamadolo okuyingxenye .
Ukuguqulwa Knee Okuyingxenye
Ukuguqulwa kwamadolo okhethekile, okubizwa nangokuthi ukuguqulwa kwamadolo okungabonakali, kusho ukuthi kuphela ingxenye engapheliyo yamadolo isuswa. Ngokuvamile, idolo lihlukaniswe ngamakamelo amathathu , ngakho-ke ukuguqulwa kwamadolo okungena emaceleni kubizwa ngokuthi yi-unicompartmental knee esikhundleni sokuthi esikhundleni sendawo eyodwa. Amakamelo amathathu ayingxenyeni yangaphakathi yamadolo, uhlangothi lwangaphandle lwamadolo, kanye nengxenye ngaphansi kwe-kneecap.

I-Patellofemoral Replacement Surgery & Recovery
Ngesikhathi sokuhlinzwa ukwenza indawo yokuguqula i-patellofemoral, udokotela ohlinzayo kufanele enze indawo engaphansi kwe-kneecap kanye ne-groove ekupheleni kwethanga lesenzeni ukuze abambe iqhaza lokufakelwa. Isihlanganisi esakhiwe ngokuvamile siba nesimo samathambo samathambo , afana nokushintshwa kwedolo elijwayelekile .

Imiphumela ye-Patellofemoral Replacement
Kunzima ukwazi ukuthi i-patellofemoral izothatha isikhathi eside kangakanani. Imiklamo yokufakelwa ishintshe kakhulu kule minyaka eyishumi edlule, enethemba lokuthi izimpande ezingcono zizoholela emiphumeleni engcono. Ngeshwa, akukho idatha eminingi yesikhathi eside, futhi sishiywe ngempela ngokulandela okufutshane.
Siyazi ukuthi eziningi zezifundo zenziwe, ukuthi iziguli ezingu-80-90% ziyoba nemiphumela emihle eminyakeni eyishumi emva kokushicilelwa kwe-patellofemoral, kodwa noma ngabe bazohlala isikhathi eside kunokungacaciswanga.
Siphinde sazi ukuthi isizathu esivame kakhulu sokuthi indawo ye-patellofemoral ngeke isetshenziswe kahle, akuyona ngenxa yenkinga ngokufakelwa, kodwa kunenkinga kuyo yonke into ehlangene negolo - ingxenye engashintshwa. Cishe iziguli ezingama-25% zizodinga ukuguqulwa kwe- patellofemoral yabo esikhundleni sendawo esikhundleni sokuguqulwa kwamadolo ngenxa yomuthi wesifo samathambo eminye emaceleni emadolweni.
Yingakho iziguli ezinemiphumela emihle kakhulu ezivela esikhundleni segama lika-patellofemoral yizo iziguli ezinezinkinga ezithile nge-kneecap yazo, njenge- patella ukuhlukana noma izinkinga zokulandelela i-patellar . Lezi zimo zingaholela ekugqokeni kokuqala kwe-cartilage ngaphansi kwe-kneecap.
