Ancak kullanım şartlarına bağlı olarak protez bileşenlerindeoluşabilecek hataların belirlenebilmesi gerekmektedir. Bu çalışmada kullanımesnasında diz eklem protez bileşenlerinden biri olan yüksek moleküleryoğunluklu ultra hafif polietilen (UHMWPE) insert bileşeninde meydana gelenhata durumlarının gözlemlenebilmesi amaçlandı. Bu nedenle diz simülatörü ileaşınma testi 1x106, 2x106 ve 3x106 olmak üzereüç farklı çevrim sayısında gerçekleştirildi. Testlerin sonunda UHMWPE insert medialve lateral kondillerden mikroskop görüntüleri ve kütle kaybı ölçümleri alındı.Elde edilen bulgularda çevrim sayısının artışına bağlı olarak UHMWPE insert bileşeniüzerinde farklı eksenlerdeki tekrarlı kuvvetler sonucunda çukurcuk aşınmalarının,kılcal çatlakların, çiziklerin, yığılmış partiküllerin ve kütle kayıplarının belirginbir şekilde oluştuğu görüldü.

However, depending on the conditions of use, it is necessary todetermine the defects that may occur in the prosthetic components. In thisstudy, it is aimed to observe the error mechanisms of ultra high molecularweight polyethylene (UHMWPE) insert component which is one of the knee jointprosthesis components during use. Therefore, the wear test with knee simulatorwas carried out in three different cycles; 1x106, 2x106and 3x106. At the end of the tests, microscop images and mass lossmeasurements were taken from the medial and lateral condyles of the UHMWPEinsert. According to the results, it is seen that due to the increase in thenumber of cycles, it is seen that pitting wear, capillary cracks, scratches,agglomerated particles and mass losses occur as a result of repetitive forceson different axes on UHMWPE insert component.
