Femoral revision component subsidence has been identified as predicting early failure in revision hip surgery. This comparative cohort study assessed the potential risk factors of subsidence in two commonly used femoral implant designs. A comparative cohort study was undertaken, analyzing a consecutive series of patients following revision total hip arthroplasties using either a tapered-modular (TM) fluted titanium or a porous-coated cylindrical modular (PCM) titanium femoral component, between April 2006 and May 2018. Clinical and radiological assessment was compared for both treatment cohorts. Risk factors for subsidence were assessed and compared.Aims
Methods
Loss or absence of proximal femoral bone in revision total hip
arthroplasty (THA) remains a significant challenge. While the main
indication for the use of proximal femoral replacements (PFRs) is
in the treatment of malignant disease, they have a valuable role
in revision THA for loosening, fracture and infection in patients
with bone loss. Our aim was to determine the clinical outcomes,
implant survivorship, and complications of PFRs used in revision
THA for indications other than malignancy. A retrospective review of 44 patients who underwent revision
THA using a PFR between 2000 and 2013 was undertaken. Their mean
age was 79 years (53 to 97); 31 (70%) were women. The bone loss
was classified as Paprosky IIIB or IV in all patients. The mean
follow-up was six years (2 to 12), at which time 22 patients had
died and five were lost to follow-up.Aims
