The aim of this project is to conduct an international multi-center joint research study to determine whether polyethylene wear debris production can be reduced in the future, using an in vivo polyethylene wear debris analysis method that the investigators developed as a method that can provide early feedback.",[95,96],"Wear of Articular Bearing Surface of Prosthetic Joint","Hip Arthropathy",[98,99],"Polyethylene wear particle","Total hip arthroplasty","2025-01-16",{"date":102,"type":103},"2025-01-20","ACTUAL",{"date":105,"type":103},"2024-06-01",{"date":107,"type":91},"2028-12-31",{"name":5,"class":6},2]
