The aim of this study was to identify the effect of the manufacturing characteristics of polyethylene acetabular liners on the survival of cementless and hybrid total hip arthroplasty (THA). Prospective cohort study using linked National Joint Registry (NJR) and manufacturer data. The primary endpoint was revision for aseptic loosening. Cox proportional hazard regression was the primary analytical approach. Manufacturing variables included resin type, crosslinking radiation dose, terminal sterilization method, terminal sterilization radiation dose, stabilization treatment, total radiation dose, packaging, and face asymmetry. Total radiation dose was further divided into G1 (no radiation), G2 (> 0 Mrad to < 5 Mrad), G3 (≥ 5 Mrad to < 10 Mrad), and G4 (≥ 10 Mrad).Aims
Methods
The purpose of this retrospective study was to evaluate the minimum
five-year outcome of revision total hip arthroplasty (THA) using
the Kerboull acetabular reinforcement device (KARD) in patients
with Paprosky type III acetabular defects and destruction of the
inferior margin of the acetabulum. We identified 36 patients (37 hips) who underwent revision THA
under these circumstances using the KARD, fresh frozen allograft
femoral heads, and reconstruction of the inferior margin of the
acetabulum. The Merle d’Aubigné system was used for clinical assessment.
Serial anteroposterior pelvic radiographs were used to assess migration
of the acetabular component.Aims
