1. Ukurikije niba ligamenti yimbere yabitswe
Ukurikije niba ligamenti yimbere yabitswe, prothèse yibanze yo gusimbuza ivi irashobora kugabanywa mugusimbuza ligamenti yimbere (Posterior Stabilized, PS) hamwe no kugumana ligamenti inyuma (Cruiate Retention, CR).Mu myaka yashize, ikibaya cya tibial yubwoko bubiri bwa prostate cyarakozwe muburyo butandukanye bwo guhuza nubugari bwinkingi yo hagati ukurikije ituze ryingingo, imikorere ya ligament hamwe nigitekerezo cyo kubaga, kugirango kunoza ituze ryihuriro no kunoza imikorere ya kinematike.
(1) Ibiranga prostate ya CR na PS:
Prothèse CR ibika inyuma yimbere yaivikandi igabanya umubare wintambwe zo kubaga;irinda gukomeza kwanga condyle femorale kandi ikabika amagufwa;mubyukuri, irashobora kongera ihindagurika ryimiterere, kugabanya paradoxical yimbere yimbere, kandi ikagera kumurongo.Ifasha kubungabunga proprioception.
Prothèse ya PS ikoresha kamera-inkingi kugirango isimbuze imikorere yumusaraba winyuma mugushushanya, kugirango prothèse femorale ishobora gusubira inyuma mugihe cyibikorwa bya flexion.Mugihe cyo gukora ,.femoral intercondylarosteotomy irakenewe.Bitewe no gukuraho ligamenti yimbere, icyuho cya flexion nini, manuveri yinyuma iroroshye, kandi uburinganire bwururimi buroroshye kandi bworoshye.
(2) Ibimenyetso bifitanye isano na prostate ya CR na PS:
Abenshi mu barwayi bafite ibibyimba byose byo mu ivi barashobora gukoresha prothèse CR cyangwa prothèse ya PS, kandi guhitamo prothèse biterwa ahanini nuburwayi nuburambe bwa muganga.Nyamara, CR prothèse CR irakwiriye cyane kubarwayi bafite imikorere isanzwe ya ligamente yimbere isanzwe, hyperplasia yoroheje yoroheje, hamwe no kutagira ubumuga bukabije.Prothèse ya PS irashobora gukoreshwa cyane mubice byinshi byibanze bisimbuza ivi, harimo abarwayi bafite hyperplasia ikabije nubumuga.Ku barwayi bafite osteoporose cyangwa inenge zifite amagufwa, hashobora gukenerwa inkoni ndende ndende, kandi hashobora gukenerwa imikorere mibi ya ligamente.Koresha icyogajuru kibuza.
2. Umwanya uhamye hamwe na prothèse yimukanwa
Ibihimbanoprothèse ifatanyeIrashobora kugabanywa muburyo butajegajega hamwe na platifike yimuka ukurikije uburyo bwo guhuza gasike ya polyethylene hamwe nicyuma cya tibial tray.Prothèse ihamye ni polyethylene igizwe na tibial plateau hakoreshejwe uburyo bwo gufunga.Igice cya polyethylene ya prothèse yimukanwa irashobora kwimuka kuri tibial plateau.Usibye gukora ingingo yimukanwa hamwe na prothèse femorale, space polyethylene inemerera urwego runaka rwo kugenda hagati yibibaya bya tibial na tibial plateau.
Igikoresho gihamye cya prothèse gasegereti gifunzwe kumurongo wicyuma, gikomeye kandi cyizewe, kandi kirakoreshwa cyane.Uburinganire bwa geometrike yimyanya ndangagitsina irashobora gutandukana cyane kubakora nuwabikoze kugirango bahuze prothèse idasanzwe yumugore no kunoza kinematiki bifuza.Irashobora kandi guhinduka byoroshye kuri shim igabanya niba bikenewe.
