Anterior cruciate ligament (ACL) kuputika kukuvara kunowanzoitika kunoonekwa kunyanya mumitambo nevakadzi, uye kazhinji kunoguma nekusagadzikana kwekushanda kunotevera.Kuvhiya kwekuvakazve kwe ACL kunoda kuderedza kurwara kunoenderana nekukuvara uku.
Siruuru inoitirwa kuti ishandiswe semudziyo wekugadzirisa bhonzo-tendon uye matishu akapfava panguva yeACL nePCL maitirwo ekuvakazve. Siruuru imwe neimwe ine dhizaini yakanyanyiswa inoita kuti torque iwedzere, sezvo sikururu yakagara zvakazara.Iyo tambo fomu yakagadziridzwa kuregedzera kupinza uye kuwedzera nyoro matishu uye bhonzo kugadzirisa mune cortical uye kanzura bhonzo.
Iyo cannulated hexalobe drive system inosimudzira mhuri yescrew nekupa imwe universal drive system yeese screws uye zvakanyanya kunatsiridza torsional nekupinza simba.Siruu imwe neimwe inogara zvizere pairi uye inotsigirwa zvizere pamwe nehurefu hwese hwetipi yemutyairi.
Kwemakore, masiruuru, imwe yeanowanzo shandiswa mishini michina, yakafambira mberi kubva kusimbi (titanium, simbi isina tsvina) kuenda kune biodegradable formulations yegraft fixation muanterior cruciate ligament (ACL) reconstruction sezvo simba rekugadzirisa re bioabsorbable screws rakaratidzwa kufananidzwa nesimbi screws.Yakawedzerwa mabhenefiti ezvitsva zvekupindira screws anosanganisira yakaderera artefact kugadzirwa panguva yekuongororwa kwemagnetic resonance imaging (MRI), njodzi dzakadzika dzegraft laceration panguva yekuisa screw, uye zvingangoita nyore kudzokorora kana munhu achinge achidikanwa.
