Thirteen-year results of cementless total hip arthroplasty with zirconia heads on highly cross-linked polyethylene

Zirconia ceramic was introduced for femoral heads because of its mechanical strength and fracture toughness. Highly cross-linked polyethylene has been shown to achieve wear reduction compared to conventional polyethylene. The purpose of this study was to investigate the long-term results of cementless total hip arthroplasty with zirconia femoral heads on highly cross-linked polyethylene.Radiographic measurements of two-dimensional femoral head...
