IdoloPi-rosthesiskuyindlela ebalulekile yokwelapha ukulimala okukhulu kwamadolo noma izifo eziwohlokayo njenge-osteoarthritis, okuhloswe ngazo ukubuyisela ukuhamba kweziguli nokuthuthukisa ikhwalithi yempilo yazo. Kubalulekile ukuqonda izingxenye ze-knee prosthesis.
Ngokuvamileidoloilungai-prosthesisinezingxenye eziningana ezibalulekile: ingxenye ye-femoral, ingxenye ye-tibial, ingxenye ye-patella njll. Namuhla sifuna ukwethula izingxenye ezintathu.
Ingxenye Yesitho Sabesifazane: Lena yingxenye yokufakelwa esetshenziselwa ukuthatha indawo ye-femur (ithambo lethanga). Ngokuvamile yenziwe ngensimbi, njenge-cobalt-chromium alloy noma i-titanium alloy, futhi yenzelwe ukufana nesimo semvelo se-femur. Ingxenye yesitho sabesifazane ibalulekile ekuhlinzekeni ukuzinza nokusekela ngesikhathi sokunyakaza.
I-Tibial Prosthesis: Isetshenziselwa ukuthatha indawo ye-tibia (ithambo lomzimba). Ngokuvamile yakhiwe ngepuleti lesisekelo lensimbi kanye ne-polyethylene liner, enikeza ukwesekwa okuthwala isisindo. Le prosthesis ibalulekile ekusatshalalisweni kwesisindo kanye nokumuncwa kokushaqeka ngesikhathi semisebenzi efana nokuhamba noma ukugijima.
I-Patella Prosthesis: Isetshenziselwa ukufaka esikhundleni se-patella futhi ngokuvamile yenziwe nge-polyethylene. Ukwakheka kwayo kuyivumela ukuthi ishelele kahle eduze kwe-femoral prosthesis, ngaleyo ndlela ifinyelele ukunyakaza kwemvelo kwamalunga edolo. Ukuqondanisa kahle i-patellar prosthesis kubalulekile ekuvimbeleni izinkinga nokuqinisekisa ukusebenza kahle.
Ngamafuphi, izingxenye ezahlukene ze- ti-itaniumki-neepi-rosthesissebenzisanani ukulingisa umsebenzi wemvelo weidolo elihlangeneIntuthuko eqhubekayo ezintweni zokwakha kanye nokuklama ithuthukise kakhulu ukusebenza kanye nokuqina kweki-neeji-ointpi-rosthetic, okuletha ithemba kanye nokuhamba okuthuthukisiwe ezigulini eziningi emhlabeni jikelele. Ukuqonda lezi zingxenye kusiza iziguli ukuthi zenze izinqumo ezinolwazi mayelana nezinketho zazo zokwelapha.
