Purpose: To compare clinical and radiographic outcomes of propensity-matched patients undergoing THA using standard versus high offset stems at five years.
Methods: The authors retrospectively reviewed a consecutive series of primary THAs performed between 01/09/2015-31/12/2017 using a fully-hydroxyapatite coated collared stem, with either a standard (n = 365) or high (n = 110) offset. Outcomes collected included: modified Harris Hip Score (mHHS), Oxford Hip Score (OHS), Forgotten Joint Score (FJS), and radiographic measurements including limb length discrepancy (LLD), stem subsidence, and stem radiolucencies.
Background: The purpose of the present study was to update and report clinical outcomes and survival of primary total hip arthroplasty using a cementless double-tapered titanium fully hydroxyapatite-coated stem at a follow-up > 30 years.
Methods: The outcomes of this series of 347 primary total hip arthroplasties were already published at a follow-up > 25 years, during which only 12 stems were revised. Since then, there were two additional stem revisions, bringing the total to 14 stem revisions (all of which also required cup revision).
Background: The risk factors for and clinical impact of radiolucent lines (RLLs) in cementless total hip arthroplasty remain contentious. The aim of this work was to describe a method of classification that has clinical significance and to identify risk factors.
Methods: A cohort of 288 subjects with unrevised Corail stems (DePuy Synthes, Warsaw, IN) were reviewed with radiographs and Oxford Hip Scores at 10 years.
Background: To report clinical outcomes and survival at a minimum of 10 years of a consecutive series of uncemented total hip arthroplasty (THA) with fourth-generation ceramic-on-ceramic (CoC) bearings and determine the incidence of articular noises, their risk factors, and impact on quality of life (QoL).
Methods: From a series of 456 CoC THAs, there were 25 revisions, 38 deceased, and 36 lost to follow-up. The remaining 357 hips were assessed at 11.
Background: For the past 2 decades, the authors have been using a long tapered cementless stem made of titanium and fully coated with hydroxyapatite for revision total hip arthroplasty. The purpose of this multicentric study is to assess clinical outcomes, radiographic outcomes, re-revision rates, and survival rates of this revision stem at a minimum 5-year follow-up.
Methods: The records of a multicentric continuous series of 335 adults undergoing revision total hip arthroplasty using the Corail revision stem (DePuy, Leeds, UK) between 2000 and 2012 were retrospectively reviewed.
