ʻO TKA Prosthesis- LDK X4 Ka ʻAha Knee Arthroplasty

TKA Prosthesis- LDK X4 Kumu Nui Total Knee Arthroplasty Kiʻi ʻia

ʻO ka wehewehe pōkole:

Hoʻohana ʻia ka X4 Knee implants no ka hoʻopau ʻana i nā hoʻopiʻi o ka mea maʻi e pili ana i nā hui kuli i hoʻopōʻino ʻia a i ʻole ka nui, ʻokoʻa i nā maʻi me ka emi ʻana o ka maikaʻi o ke ola ma muli o ka ʻeha e pili ana i ka arthrosis. ʻO nā prostheses hui kuli nā ʻāpana aʻe; nā ʻāpana femoral, nā mea hoʻokomo, nā ʻāpana tibial, nā kumu, nā pegs, nā nati, nā ʻāpana patellar.

Hāʻawi ʻia ka condyle mua o ka prosthesis femoral me ka liʻiliʻi o ka laulā a me ka mānoanoa e hoʻemi ai i ke kaomi condyloid anterior a me ka ʻeha quadriceps. ʻO ka geometry sagittal like a me ka curvature maʻemaʻe e ʻae i ka patella ʻaʻole e hoʻonui i ka ikaika o ka quadriceps femoris i ka wā e kīloi ai ke kuli. I ka hui pū ʻana me ka hohonu patellar trochlear groove, hiki ke hōʻoia i ka paʻa ʻana o ka patella a i loko o ke kaʻe a hiki i ka flexion kiʻekiʻe me ka ʻole o ka dislocation, a mālama ʻia ka pilina paʻa ma waena o ka patella a me ka prosthesis femoral i nā manawa a pau.

Hoʻolālā ʻia ka prosthesis femoral me kahi mokulele coronal curved liʻiliʻi e hoʻonui i ka wahi hoʻopili i mea e hōʻemi ai i ke kaomi kiʻekiʻe ma ka hoʻokomo polyethylene. Hoʻopau ʻia ke kuʻekuʻe kikoʻī i ka wā o ka hoʻololi ʻana o ka varus-valgus o ke kuli, no laila e mālama mau ka hui tibiofemoral i ke alo a me ke alo.

ʻO ka notch patellar anterior o ka polyethylene insert e hoʻemi ana i ke kaomi hou a me ka haʻalulu ma luna o nā quadriceps femoris i ka wā kiʻekiʻe flexion.

Hoʻonui ʻia ka curvature condylar hope. ʻO ka ʻili o ka tibiofemoral articular e hoʻomau i ka hoʻopili ʻana i ka ʻili ma mua o ke kiko kikoʻī inā piʻi ka flexion i 135 degere.

Open intercondylar fossa design: Hoʻemi ʻia ka intercondylar osteotomy, a mālama ʻia ka iwi i ka nui loa no ka mea maʻi.

ʻO ka hoʻolālā cam-post maikaʻi loa: Ke mālama mau ʻia ke kāmela ma ke kumu o ke kolamu ʻoiai ke kuʻekuʻe kiʻekiʻe o ke kuli, e pale ana i ka hiki ʻana mai o ka dislocation cervical i ka wā o ka flexion kiʻekiʻe i kahi palena palena.

Hāʻawi ʻia kahi mīkini laka hoʻokomo ʻokoʻa. Hiki i ka hoʻopaʻa lua me nā heleuma metala ke hoʻopau i ka ʻaʻahu ʻeha ma waena o nā mea ʻelua.

ʻO ke ʻano ʻēheu ʻekolu e pale i ka hoʻololi ʻana a pale aku i ke koʻikoʻi koʻikoʻi.
