An open source software tool to assign the material properties of bone for ABAQUS finite element simulations
A new software tool to assign the material properties of bone to an ABAQUS finite element mesh was created and compared with Bonemat, a similar tool originally designed to work with Ansys finite element models. Our software tool...

Topographical and chemical effects of electrochemically assisted deposited hydroxyapatite coatings on osteoblast-like cells

A recently commercialised hydroxyapatite electrochemically assisted chemical deposition technique (BoneMaster) has been shown to induce increased bone apposition; whether this response is caused by the surface topography or...

Characterisation of the physical, chemical and mechanical properties of a radiopaque polyethylene
Ultra-high molecular weight polyethylene has a low X-ray attenuation, hence, the performance of the polyethylene implants used for joint replacements cannot be directly investigated using X-ray-based imaging techniques. In this...

The role of imaging in follow-up of newly introduced implants
A wide variety of orthopaedic implants is in clinical use and many new devices are brought to the market each year. The vast majority of these devices have no published clinical data. The concept of phased introduction has been...

Clinically useful finite element models of the natural ankle – a review
Background:
Biomechanical simulation of the foot and ankle complex is a growing research area but compared to simulation of joints such as hip and knee, it has been under investigated and lacks consistency in research...

Knee replacement for osteoarthritis

Knee replacement is one of the commonest surgical procedures performed in older adults, and its incidence is increasing rapidly. It is the only curative procedure for knee osteoarthritis, and it has excellent outcomes overall...

Mono-functional aminosilanes as primers for peptide functionalization

When covalently attaching biomolecules to surfaces such as titanium, trifunctional silanes are commonly used as primers to produce surface amine groups. However, these primed surfaces are rarely uniform in structure due to...

Minimising Tibial Fracture after Unicompartmental Knee Replacement

Background: Periprosthetic tibial fracture after unicompartmental knee replacement is a challenging post-operative complication. Patients have an increased risk of mortality after fracture, the majority undergo further...

A semi-automated measurement technique for the assessment of radiolucency
The assessment of radiolucency around an implant is qualitative, poorly defined and has low agreement between clinicians. Accurate and repeatable assessment of radiolucency is essential to prevent misdiagnosis, minimize cases of...

Are there clinically relevant anatomical differences of the proximal femur in patients with mild dysplastic and primary hip osteoarthritis? A CT-based matched-pairs cohort study

AIM: To investigate the three-dimensional anatomy and shape of the proximal femur, comparing patients with secondary osteoarthritis (OA) due to mild developmental dysplasia of the hip (DDH) and primary hip OA. MATERIALS AND...

Comparison of native anatomy with recommended safe component orientation in total hip arthroplasty for primary osteoarthritis
The adverse consequences of impingement, dislocation, and implant wear have stimulated increasing interest in accurate component orientation in total hip arthroplasty and hip resurfacing. The aims of the present study were to...

Posterior Bearing Overhang Following Medial and Lateral Mobile Bearing Unicompartmental Knee Replacements

This study explores the extent of bearing overhang following mobile bearing Oxford unicompartmental knee replacement (OUKR) (Oxford Phase 3, Zimmer Biomet). The Oxford components are designed to be fully congruent, however...

Prediction of three-dimensional femoral offset from AP pelvis radiographs in primary hip osteoarthritis
BACKGROUND: In pre-operative planning for total hip arthroplasty (THA), femoral offset (FO) is frequently underestimated on AP pelvis radiographs as a result of inaccurate patient positioning, imprecise magnification, and...
