Ungakhetha njani i-prosthesis yedolo?

Idolo elidibeneyo elenziweyoyenziwe yinxalenye ye-femur, inxalenye ye-tibia kunye ne-patella, enokulinganisa umsebenzi welungu ledolo lomntu kwaye ithathe indawo yamalungu agulayo okanye onakeleyo.

Indlela yokukhethaidolo lokufakelwa?
Okwangoku, i-knee arthroplasty inokwahlulwahlulwa ibe yi-partial knee arthroplasty (i-unicompartmental knee arthroplasty) kunye ne-total knee arthroplasty (TKA).

I-Partial knee arthroplasty (i-unicompartmental arthroplasty)
Ukufakelwa Kwamadolo Okungaphelelangayindlela yokutshintsha umphezulu wokwenyani engenazintlungu zingako zotyando, ukugcinwa kwemisipha ebuhlungu yangaphambili nengasemva, ukubuyiselwa ngokukhawuleza kokusebenza kwamalungu emva kotyando, kufutshane nokuhamba kwedolo okuqhelekileyo, kunye nokuhamba kakuhle kwamalungu kunye nokuhamba kwawo kunokufumaneka. Ngeenzuzo kunye neempawu ezikhethekileyo, isebenza njengonyango olukhethwayo lwezilonda ezivaleleke kwigumbi elinye le-tibiofemoral edolweni. Nangona kunjalo, i-UKA ineempawu ezimbalwa kunye nesantya esiphezulu sokukhululeka kwe-tibial emva kotyando, okuthintela ukusetyenziswa kwe-UKA kwiimeko zonyango.

I-Implant Etshintshiweyo Yesinqe iyonke
Ukufakelwa Kwamadolo OkupheleleyoZisetyenziswa kakhulu kwi-knee arthroplasty. Iintlobo eziphambili ezisetyenziswayo kwezonyango zezi zilandelayo:
I-prosthesis egcina i-Posterior Cruciate Lligament: Leidolo lokufakelwaIxhomekeke kakhulu kwi-posterior cruciate ligament yelungu, ukuze kuqinisekiswe uzinzo lwangasemva lwe-tibia. Ingena kakuhle kwaye ayinayo imiqathango ingako. Uxinzelelo olubangelwa kukuhamba kwamalungu abantu lufunxwa yi-ligament, kwaye uxinzelelo lwe-prosthesis luyancipha kakhulu. Kutyando lwamalungu ngokugcinwa kwe-posterior ligament, umthwalo kwinxalenye yangasemva yelungu mkhulu kakhulu, nto leyo enokunyusa ukuguguleka kwe-polyethylene insert yelungu. Ke ngoko, kusafuneka ifundwe ngakumbi kwaye iphuculwe kwindlela yokusebenza kweklinikhi.

I-prosthesis engenalo i-Ligament emva kwe-Cruciate: Uyilo lwaleidoloi-prosthesisIgxile ekwandiseni izinga lokuzinza nokunciphisa uxinzelelo xa idibene ne-prosthesis. Inezinga eliphezulu le-anastomosis kwaye idla ngokuba noyilo lwe-CAM. Iingenelo zayo ziquka ukususwa kwe-posterior cruciate ligament, inika ulungelelwano kunye nokuzinza kwimisebenzi yokujika kunye nokwandisa; Ukwandisa ukujika kwamalungu ngokwandisa umsantsa wokujika; I-prosthesis inozinzo oluphezulu kwaye ikwafanelekile kwizigulana ezine-knee valgus kunye ne-flexion deformity. Iingxaki zayo zezi zilandelayo: izinga eliphezulu le-gap anastomosis lenza uxinzelelo lugxile kwi-prosthesis, lonyusa umthwalo wecandelo le-femoral, kwaye linezinga eliphezulu lokukhululeka kade kune-posterior cruciate ligament-preserving prosthesis. Ubungakanani bethambo elisuswe ngokufakelwa kwe-prosthesis likhulu kakhulu, nto leyo eyenza utyando lokuhlaziya lube nzima ngakumbi. I-posterior cruciate ligament-free prosthesis ineempawu ezininzi, kwaye inkqubo ethile yotyando ilula. Luhlobo lwe-prosthesis olusetyenziswa kakhulu kunyango lwezonyango okwangoku.
