1. Bisa ga ko an kiyaye ligament na baya
Dangane da ko an kiyaye ligament na baya-bayan nan, za a iya raba na farko na wucin gadi na wucin gadi na wucin gadi zuwa maye gurbin ligament na baya (Posterior Stabilized, PS) da kuma riƙewar haɗin gwiwa na baya (Cruiate Retention, CR).A cikin 'yan shekarun nan, Filin Tibal na waɗannan nau'ikan persthess guda biyu an tsara su da digiri daban-daban da nisa na Tsakiya bisa ga kwanciyar hankali, aikin jita da manufar likitan tiyata, don haka inganta kwanciyar hankali na haɗin gwiwa kuma inganta aikin kinematic.
(1) Siffofin CR da PS prostheses:
CR prosthesis yana kiyaye ligament na baya na cruciategwiwa gwiwakuma yana rage yawan matakan tiyata;yana guje wa ƙarin reshe na condyle na mata kuma yana kiyaye yawan kashi;A bisa ka'ida, yana iya ƙara kwanciyar hankali, rage matsuguni na gaba, da cimma juyawar baya.Taimakawa kiyaye sanin yakamata.
PS prosthesis yana amfani da tsarin cam-column don maye gurbin aikin giciye na baya a cikin zane, ta yadda za a iya jujjuya gashin mata a yayin ayyukan sassauƙa.A lokacin aikin, daintercondylar femoralana buƙatar osteotomy.Saboda cirewar ligament na baya, raguwar raguwa ya fi girma, motsi na baya yana da sauƙi, kuma ma'auni na ligament ya fi sauƙi kuma mafi sauƙi.
(2) Alamun dangi na CR da PS prostheses:
Yawancin marasa lafiya da ke jurewa jimillar jimillar ƙwanƙwasa gwiwa na iya amfani da ko dai CR prosthesis ko PS prosthesis, kuma zaɓin gyaran gyare-gyaren ya dogara ne akan yanayin mai haƙuri da ƙwarewar likita.Duk da haka, CR prosthesis ya fi dacewa da marasa lafiya tare da aikin ligament na baya na yau da kullum, ƙananan hyperplasia na haɗin gwiwa, da ƙananan nakasar haɗin gwiwa.PS prostheses za a iya amfani da ko'ina a mafi na farko jimlar maye gurbin gwiwa, ciki har da marasa lafiya da mai tsanani hyperplasia da nakasa.A cikin marasa lafiya masu fama da osteoporosis mai tsanani ko lahani na kashi, ana iya buƙatar sanduna masu tsayi na intramedullary, kuma ana iya buƙatar rashin aikin haɗin gwiwa.Yi amfani da tazara mai takurawa.
2. Kafaffen dandamali da prosthesis dandamali mai motsi
The wucin gadigwiwa hadin gwiwa prosthesisza a iya raba kafaffen dandali da kuma m dandamali bisa ga dangane Hanyar polyethylene gasket da karfe tibial tire.Kafaffen dandali prosthesis wani abu ne na polyethylene wanda aka gyara zuwa ga tudun tibial ta hanyar kullewa.Bangaren polyethylene na prosthesis dandamali mai motsi na iya motsawa akan tudun tibial.Bugu da ƙari don samar da haɗin gwiwa mai motsi tare da prosthesis na mata, polyethylene spacer kuma yana ba da damar wani mataki na motsi tsakanin tibial plateau da tibial plateau.
A kafaffen dandali prosthesis gasket an kulle a kan karfe sashi, wanda yake m da kuma abin dogara, kuma an fi amfani da ko'ina.Geometries na masu gyara sararin samaniya na iya bambanta ko'ina daga masana'anta zuwa masana'anta don dacewa da ƙayyadaddun prosthesis na mata da inganta kinematics da ake so.Hakanan ana iya canza shi cikin sauƙi zuwa shim mai ƙuntatawa idan an buƙata.
