Moro T1,2, Takatori Y1,2, Kyomoto M1,3,4, Ishihara K3, Kawaguchi H5, Hashimoto M6, Tanaka T2, Oshima H2, Tanaka S2.
Journal of orthopaedic research : official publication of the Orthopaedic Research Society.J Orthop Res.2015 Jul;33(7):1103-10. doi: 10.1002/jor.22868. Epub 2015 Apr 6.
The use of larger femoral heads to prevent the dislocation of artificial hip joints has recently become more common. However, concerns about the subsequent use of thinner polyethylene liners and their effects on wear rate have arisen. Previously, we prepared and evaluated the biological and mechanic
