TKA Prosthesis- LDK X4 Primary Total Knee Arthroplasty
1.
Iyo anterior condyle yefemoral prosthesis inopiwa nehupamhi hwakadzikiswa uye ukobvu kudzikisa anterior condyloid pressure uye quadriceps tension.Iyo yakafanana sagittal geometry uye yakatsetseka curvature inobvumira patella kuti isawedzere simba re quadriceps femoris apo ibvi rinotambanudza uye rinoputika.Mukubatana neyakadzama patellar trochlear groove, inogona kuve nechokwadi kuti patella yakagadzikana uye mu groove kunyange mukukwirira kwepamusoro pasina kuputika, uye kugadzikana kunobata pakati pepatella uye femoral prosthesis inochengetwa nguva dzose.
2.
Iyo femoral prosthesis yakagadzirwa neine zvishoma yakakombama coronal ndege kuti iwedzere nzvimbo yekubata kuti ideredze peak pressure pane polyethylene inopinza.Iko-ku-point-kumucheto kubereka kunobviswa panguva yevarus-valgus kutenderera kwemabvi, kuitira kuti tibiofemoral joint nguva dzose inochengetedza chiso nechiso.
3.
Iyo anterior patellar notch yepolyethylene inopinza inoderedza kuwedzera kudzvanywa uye tension pa quadriceps femoris panguva yekukwirira kwepamusoro.
4.
Iyo posterior condylar curvature inowedzera.Iyo tibiofemoral articular surface inoramba iri pamusoro pekubata panzvimbo yepoindi yekubata kana kuchinjika kwasvika 135 madhigirii.
5.
Vhura intercondylar fossa design: The intercondylar osteotomy yakaderedzwa, uye pfupa rinochengetwa kusvika pamwero mukuru kune murwere.
6.
Yakagadziridzwa cam-post chimiro: Iyo cam ichiri kuchengetwa pazasi pembiru apo ibvi riri muhupamhi hwepamusoro, kudzivirira kuitika kweiyo cervical dislocation panguva yekukwirira kwepamusoro kusvika padiki.
7.
Imwe yakasarudzika yekukiya yekukiya michina inopihwa.Kugadziriswa kwechipiri nesimbi anchors kunogona kubvisa kushungurudza kupfeka pakati pezviviri.
8.
Iyo yetatu-wing chimiro inodzivirira kutenderera uye inodzivirira kushushikana kushushikana.
