Conclusion Total hip arthroplasty in patients younger than 55 years provides reliable outcomes at up to 10 years .
Background Total hip arthroplasty ( THA ) is increasingly performed in younger patients despite the lack of comprehensive assessment of long-term outcomes .
We systematic ally review ed the contemporary literature to assess the 1 ) indications , 2 ) implant selection and long-term survivorship , 3 ) complication and reoperation rates and 4 ) radiographic and functional outcomes of primary THA in patients younger than 55 years .
Minimum five-year follow-up wear measurement of longevity highly cross-linked polyethylene cup against cobalt-chromium or zirconia heads.
We investigated the efficacy of combining highly cross-linked polyethylene with ceramic heads on further reduction in polyethylene wear compared with the combination with cobalt-chromium heads via PolyWare computer-assisted method . A prospect i ve cohort study was performed on 102 cementless total hip arthroplasties using Longevity ( Zimmer , Warsaw , Ind ) highly cross-linked polyethylene liners . Either  26-mm zirconia heads or 26-mm cobalt-chromium heads were r and omly used in 51 hips each . At a mean follow-up of 6.7 years , no significant differences were identified between the groups for total penetration rate and steady-state wear rate . Osteolysis was not observed in any hips in either group . In conclusion , no advantage was seen for the 26-mm zirconia head compared with the 26-mm cobalt-chromium head in this period
