The increased number of joint prostheses now being implanted into younger and active patients has made wear on polyethylene more apparent. This wear is the consequence of the bearing surface of polyethylene against metal. Research into the problem of wear is complex and other models such as metal-on-metal implants, ceramic-on-ceramic implants are tried to decrease the amount of particles accumulated after wear and avoid inflammatory reactions leading to bone lysis and implant loosening between 10 and 20 years.
现在植入年轻且活跃患者体内的关节假体数量不断增加，使得聚乙烯的磨损更加明显。这种磨损是聚乙烯与金属的承重表面相互作用的结果。对磨损问题的研究很复杂，人们尝试了其他模型，如金属对金属植入物、陶瓷对陶瓷植入物，以减少磨损后积累的颗粒数量，并避免在10至20年期间导致骨溶解和植入物松动的炎症反应。
