Revision rates after primary hip and knee replacement in England between 2003 and 2006 [PDF]
, 2008 <b>Background</b>: Hip and knee replacement are some of the most frequently performed surgical procedures in the world. Resurfacing of the hip and unicondylar knee replacement are increasingly being used.

Two-dimensional finite element simulation of fracture and fatigue behaviours of alumina microstructures for hip prosthesis [PDF]
Proceedings of the Institution of Mechanical Engineers, Part H:
Journal of Engineering in Medicine 225, 12 (2011) 1158-1168, 2012 This paper describes a two-dimensional (2D) finite element simulation for fracture and fatigue behaviours of pure alumina microstructures such as those found at hip prostheses. Finite element models are developed using actual Al2O3 microstructures and a bilinear cohesive zone law. Simulation conditions are similar to those found at a slip zone in a dry

Finite element modelling of shock-induced damages on ceramic hip prostheses [PDF]
ISRN Materials Science (2011) ID 121486, 2012 The aim of this work was to simulate the behaviour of hip prostheses under mechanical shocks. When hip joint is replaced by prosthesis, during the swing phase of the leg, a microseparation between the prosthetic head and the cup could occur. Two different sizes of femoral heads were studied: 28 and 32 mm diameter, made, respectively, in alumina and ...

Patient-individual hip cups: simulation-based design and sheet metal forming manufacturing [PDF]
, 2013 The revision of an hip prosthesis can have different reasons. One frequent cause, especialley after implantation of a conventional cup, is the so called stress-shielding effect which can lead to a migration or loosening.

Loosened hip joint prosthesis-decision options
Journal of the Bulgarian Orthopaedics and Trauma AssociationFor the period 2013-2015, 36 patients underwent revision surgery because of secondary developed complications after primary hip joint replacement surgery. 14 of them were male and 23 – female, with average age 73 years.

Prospective five-year subsidence analysis of a cementless fully hydroxyapatite-coated femoral hip arthroplasty component [PDF]
, 2014 Early subsidence >1.5 mm is considered to be a predictive factor for later aseptic loosening of the femoral component following total hip arthroplasty (THA).

Enzymes and cytokines disease in total hip arthroplasty: promoters of immune loosening
Revista de la Facultad de Medicina, 2018 Introduction: An important cause of hip prosthesis failure is loosening related to cytokine-mediated release of enzymes that produces lysis of the bone that supports the implant.
