1. E like me ka mālama ʻana i ka ligament cruciate hope
Ma muli o ka mālamaʻiaʻana o ka ligament hope, hiki ke hoʻokaʻawaleʻia ka prosthesis pani pani pani mua i ka hope (Posterior Stabilized, PS) a me ka paʻa hope (Cruiate Retention, CR). I kēia mau makahiki i hala iho nei, ua hoʻolālā ʻia ka pāpū tibial o kēia mau ʻano prostheses ʻelua me nā degere like ʻole a me ka laulā o ke kolamu waena e like me ke kūpaʻa o ka hui, ka hana o ka ligament a me ka manaʻo o ke kauā, i mea e hoʻomaikaʻi ai i ke kūpaʻa o ka hui a hoʻomaikaʻi i ka hana kinematic.
(1) Nā hiʻohiʻona o CR a me PS prostheses:
Mālama ka CR prosthesis i ka ligament cruciate hope o kaami kulia e hoemi ana i ka heluna o na anuu hana; pale ia i ka wehe hou ʻana o ka condyle femoral a mālama i ka nui o ka iwi; theoretically, hiki ke hoʻonui i ka flexion stability, ho'ēmi i ka paradoxical anterior displacement, a hoʻokō i ka holo hope. Kōkua i ka mālama ʻana i ka proprioception.
Hoʻohana ka prosthesis PS i kahi hoʻolālā cam-column e pani i ka hana o ke keʻa hope i ka hoʻolālā, i hiki ke ʻōwili ʻia ka prosthesis femoral i ka wā o nā hana flexion. I ka wā o ka hana, kafemoral intercondylarPono ka osteotomy. Ma muli o ka weheʻiaʻana o ka ligament cruciate hope,ʻoi aku ka nui o ka flexion gap, ka maʻalahi o ka hana hope, aʻoi aku ka maʻalahi o ke kaulike ligament a me ka pololei.
(2) Nā hōʻailona pili o CR a me PS prostheses:
ʻO ka hapa nui o nā maʻi e loaʻa ana i ka arthroplasty kuli holoʻokoʻa hiki ke hoʻohana i ka prosthesis CR a i ʻole ka prosthesis PS, a ʻo ke koho ʻana i ka prosthesis e hilinaʻi nui ʻia i ke kūlana o ka mea maʻi a me ka ʻike o ke kauka. Eia nō naʻe, ʻoi aku ka maikaʻi o ka prosthesis CR no nā poʻe maʻi me ka hana maʻamau maʻamau o hope cruciate ligament, hyperplasia hui haʻahaʻa, a me nā deformity hui liʻiliʻi. Hiki ke hoʻohana nui ʻia nā prostheses PS i ka hapa nui o nā kuli holoʻokoʻa mua, me ka poʻe maʻi me ka hyperplasia koʻikoʻi a me ka deformity. I nā poʻe maʻi me ka osteoporosis koʻikoʻi a i ʻole nā iwi kīnā, pono ke koi ʻia nā koʻokoʻo hoʻolōʻihi intramedullary, a pono paha ke koi ʻia ʻana o ka ligament collateral dysfunction. E hoʻohana i nā spacers paʻa.
2. Pa'a pa'a a me movable anuu prosthesis
ʻO ka mea hanaprosthesis ami kuliHiki ke hoʻokaʻawale ʻia i ke kahua paʻa a me ka paepae neʻe e like me ke ʻano pili o ka polyethylene gasket a me ka pahu tibial metala. ʻO ka prosthesis paʻa paʻa he mea polyethylene i hoʻopaʻa ʻia i ka pāpū tibial e kahi mīkini laka. Hiki ke neʻe ka ʻāpana polyethylene o ka prosthesis paepae hoʻoneʻe ma ka pāpū tibial. Ma waho aʻe o ka hoʻokumu ʻana i kahi hui hoʻoneʻe me ka prosthesis femoral, hiki i ka polyethylene spacer ke ʻae i kahi pae o ka neʻe ʻana ma waena o ka pāpū tibial a me ka pāpū tibial.
Hoʻopaʻa ʻia ka gasket prosthesis paepae paʻa ma ka bracket metala, ʻo ia ka paʻa a hilinaʻi, a ʻoi aku ka nui o ka hoʻohana ʻana. Hiki ke ʻokoʻa nā geometries o nā spacers fixation mai ka mea hana a i ka mea hana e hoʻohālikelike i kā lākou prosthesis femoral kū hoʻokahi a hoʻomaikaʻi i nā kinematics i makemake ʻia. Hiki ke hoʻololi maʻalahi i kahi shim palena inā makemake ʻia.
