However, whether the geometry of prosthesis stem has an effect on patient prognosis is unclear.

However, intraoperative fractures occurred significantly less in the tapered group (4.5%) than in the cylindrical group (14.8%), and stem subsidence was significantly less in the tapered group (2.17\u2009mm) than in the cylindrical group (4.17\u2009mm). A higher ratio of bone repair and lower bone loss were observed in the tapered group compared with the cylindrical group.
