I-TKA Prosthesis- LDK X5 Primary Total Knee Arthroplasty
1.
Ibhokisi ye-intercondylar evulekileyo evulekileyo iqinisekisa ukufakwa kwe-prosthesis ezinzileyo kunye ne-osteotomy encinci.
2.
Iingqungquthela ze-condylar zangasemva ezineemitha eziphuculweyo ezigqityiweyo zikhokelela kwii-angles ezikhuselekileyo eziphakamileyo ukuya kwii-150 degrees.
3.
Umphezulu we-patellar articular olungiselelweyo, ubunzulu be-patellar groove kunye nobubanzi be-engile ye-Q ebanzi iqinisekisa ukuba i-patella inomzila ongcono wokunyakaza ukunqanda ngokufanelekileyo ukukhutshwa kwepatellar.
4.
I-condylar curvature yangasemva iyanda.I-tibiofemoral articular surface ihlala idibene nomphezulu kunokuba i-point contact xa i-flexion ifikelela kwi-135 degrees.
5.
I-curvature yecandelo eguqukayo kunye nenkcazo kunye nomgama ophakathi kwe-arc yecandelo kukhokelela ekufaniseni okuzinzileyo kwi-condyle ye-femal kunye nomgangatho ophantsi wokugqoka.
