In the operation of partial knee replacement, the diseased bone and tissue are removed and the remaining bone is shaped with the operating instruments to allow the components to fit exactly. Operating on the joint comprises the following four steps: Step 1 The surgeon makes an appropriate length incision down the front of the knee and flexes the joint. The surgeon removes the meniscus and any other structures that are impairing the normal movement of the joint and any possible osteophytes. Using the implant specific instruments supplied by the manufacturer of the prosthesis, the surgeon cuts and shapes the bone to the correct shape to match the internal geometry of the components to be implanted. The knee joint is prepared for the prosthesis; the defect can be seen clearly. After the final cut has been made and all the holes drilled, a trial prosthesis is inserted. This allows the exact size and optimal position of the implant to be determined. This step is decisive for subsequent mobility and stability. The femur and tibia are trimmed in such a way that the implant will fit exactly. Step 3 The surgeon implants the components and fixes them with bone cement. It is a stable connection between the surface of the im- plant and the bone. The bone cement is very compatible and hardens fully in a few minutes. The two individual components of the partial knee replacement are put into place; the knee is once again fully functional. Step 4 The surgeon sutures the joint layer by layer before applying a compression dressing. X-ray check of the implant following a successful operation: the fit is optimal.

I oibriú athsholáthair glúine páirteach, an cnámh agus fíochán ghalraithe a bhaint agus is é an cnámh fágtha múnlaithe leis na hionstraimí ag feidhmiú chun go bhféadfaidh an comhpháirteanna a d'oirfeadh go díreach. Oibriúcháin ar an comhpháirteach comhdhéanta de na ceithre céimeanna seo a leanas: Céim 1 Déanann an máinlia incision fhad iomchuí síos ar an os comhair an ghlúin agus flexes an comhpháirteach. Cuireann an máinlia an mheiniscis agus aon struchtúr eile a chuireann isteach go gluaiseacht gnáth ar an comhpháirteach agus aon osteophytes is féidir. Ag baint úsáide as na huirlisí implant sonrach ag an monaróir an próistéise, na laghduithe Máinlia agus cruthanna an cnámh leis an cruth ceart a mheaitseáil leis an geoiméadracht inmheánach de na comhpháirteanna a bheidh le ionchlannú. Is é an comh-glúine ullmhaíodh do próistéise; Is féidir an locht a bheith le feiceáil go soiléir. Tar éis an gearrtha deiridh déanta agus na poill druileáilte, Tá triail próistéise isteach. Ligeann sé seo an méid cruinn agus seasamh is fearr is féidir ar an implant a chinneadh. Is é an chéim cinntitheach do shoghluaisteacht ina dhiaidh sin agus cobhsaíocht. Tá an femur agus tibia a bearrtha ar bhealach go mbeidh an implant oiriúnach go díreach. Céim 3 Implants na Máinlia na comhpháirteanna agus Ceartúcháin iad le stroighin cnámh. Is nasc cobhsaí idir an dromchla an im- gléasra agus an cnámh. Is é an stroighin cnámh an-comhoiriúnach lena chéile agus hardens go hiomlán i gceann cúpla bomaite. Tá an dá comhábhair aonair an athsholáthair glúine páirteach a chur i bhfeidhm; Is é an ghlúin arís ag feidhmiú go hiomlán. Céim 4 An comhuaimeacha máinlia an ciseal comhpháirteach ón ciseal roimh iarratas a chóiriú comhbhrú. X-ghathaithe a sheiceáil ar an implant tar éis oibriú go rathúil: Is é an oiriúnach is fearr is féidir.
