Joini yebvi rekugadzirainoumbwa nechikamu chefemur, chikamu chetibia uye patella, izvo zvinogona kutevedzera mashandiro egumbo remunhu uye kutsiva majoini ane chirwere kana akakuvara.
Maitiro ekusarudzachigadzirwa chebvi?
Parizvino, kupatsanurwa kwebvi kunogona kukamurwa kuita zvikamu zviviri: partial knee arthroplasty (unicompartmental knee arthroplasty) uye total knee arthroplasty (TKA).
Kuvhiyiwa kwebvi rakati sandara (unicompartmental arthroplasty)
Kudyara Mabvi Parutiviinotsiva nzvimbo chaiyo isina kukuvara kwakanyanya kwekuvhiyiwa, kuchengetedzwa kwemagomarara epamberi nepashure, kupora nekukurumidza kwekushanda kwemajoini mushure mekuvhiyiwa, kufamba kwebvi kwakajairika, uye kufamba zvakanaka kwemajoini kunogona kuwanikwa. Nezvakanakira nezviratidzo zvakasiyana, inoshanda seimwe yenzira dzinofarirwa dzekurapa maronda akavharirwa muchikamu chimwe chete chebvi chetibiofemoral. Zvisinei, UKA haina zviratidzo zvakawanda uye mwero wakakwira wekusunungura kwechikamu chetibial mushure mekuvhiyiwa, izvo zvinoderedza kushandiswa kweUKA muzviitiko zvekiriniki.
Kudyara Kwakakwana Kwehudyu
Kudyarwa Kwemabvi Kweseanoshandiswa zvakanyanya mukurapa mabvi. Mhando huru dzinoshandiswa mukurapa ndeidzi dzinotevera:
Posterior Cruciate Lligament-preserving prosthesis: Izvikubatanidzwa kwebviInonyanya kushandiswa pa posterior cruciate ligament yejointi, kuitira kuti posterior tibia igare zvakanaka. Haina kukwana zvakanyanya uye ine muganho mudiki. Kushushikana kunokonzerwa nekufamba kwemajointi emunhu kunotorwa ne ligament, uye kumanikidzwa kweprosthesis kunoderedzwa zvikuru. Mukuvhiyiwa kwemajointi nekuchengetedzwa kweposterior ligament, mutoro uri paposterior ligament yejointi wakakura, izvo zvinogona kuwedzera kupfeka kwe polyethylene insert yeprosthesis. Nokudaro, ichiri kuda kudzidzwa zvakanyanya uye kuvandudzwa mukurapa.
Posterior Cruciate Ligament-free prosthesis: Dhizaini yeiyimajoini ebvikugadzira nhengoYakatarisana nekuwedzera mwero wekugadzikana uye kuderedza kushushikana pakubata neprosthesis. Ine mwero wepamusoro we anastomosis uye inowanzo kuve neCAM design. Zvakanakira zvayo zvinosanganisira kubviswa kwe posterior cruciate ligament, kupa kuenzana uye kugadzikana kwekuita mabasa ekutenderera nekuwedzera; Kuwedzera kutenderera kwemajoini nekuwedzera mukaha wekutenderera; Prosthesis ine kugadzikana kwakanyanya uye yakakodzerawo varwere vane knee valgus uye flexion deformity. Zvakashata zvayo ndeizvi: mwero wepamusoro we gap anastomosis inoita kuti kushushikana kuwedzere kuburikidza neprosthesis, kunowedzera mutoro we femoral section, uye ine mwero wepamusoro wekusunungurwa kunonoka kupfuura posterior cruciate ligament-preserving prosthesis. Huwandu hwemapfupa anobviswa neprosthesis hwakakura, izvo zvinoita kuti kuvhiyiwa kwekudzokorora kuve kwakaoma. Prosthesis ye posterior cruciate ligament-free ine zviratidzo zvakasiyana-siyana, uye nzira chaiyo yekuvhiya iri nyore. Imhando yeprosthesis inoshandiswa zvakanyanya mukurapa pari zvino.
Kana uchida kudzidza zvakawanda nezvekneedarheumatoplastyichidyarwaruzivo, ndapota inzwa wakasununguka kutaura nesu; timu yedu ichakupa rutsigiro rwehunyanzvi nemhinduro.
