Kazhinjiibvijoinikugadzira nhengoine zvikamu zvakakosha zvakati wandei: chikamu chefemoral, chikamu chetibial, chikamu chepatella nezvimwewo. Nhasi tinoda kusuma zvikamu zvitatu izvi.
Chikamu cheFemoral: Ichi chikamu cheprosthesis chinoshandiswa kutsiva femur (pfupa rechidya). Chinowanzogadzirwa nesimbi, senge cobalt-chromium alloy kana titanium alloy, uye chakagadzirwa kuti chifanane nechimiro chechisikigo chefemur. Chikamu chefemoral chakakosha pakupa kugadzikana uye rutsigiro panguva yekufamba.
Kugadzirwa kweTibial Prosthesis: Kunoshandiswa kutsiva tibia (musana). Kazhinji kunoitwa nesimbi uye polyethylene liner, iyo inotsigira huremu. Kugadzirwa uku kwakakosha pakugovera huremu uye kunyudza kuvhunduka panguva yemabasa akadai sekufamba kana kumhanya.
Patella Prosthesis: Inoshandiswa kutsiva patella uye inowanzogadzirwa ne polyethylene. Magadzirirwo ayo anoibvumira kutsvedza zvakanaka pamwe chete ne femoral prosthesis, zvichiita kuti ikwanise kufamba-famba nemabvi. Kurongeka kwakakodzera kwepatellar prosthesis kwakakosha kudzivirira matambudziko uye kuona kuti inoshanda zvakanaka.
