Development of subject specific finite element models of the mouse knee joint for preclinical applications

Finite Element Models of the Knee Joint with increasing complexity
Osteoarthritis affects the properties of the joints, changing its shape and mechanical response, and inducing pain to the patient. Mouse models are commonly used to identify the effect of mechanical instability of the joint on its structure and to optimise treatments for reducing the joint degeneration. Computational models can be used to better understand the effect of the de...

PTH(1–34) treatment and/or mechanical loading have different osteogenic effects on the trabecular and cortical bone in the ovariectomized C57BL/6 mouse

Figure showing increased apposition of bone (in red) when combining treatment (ML+PTH and ML+PTHalt), particularly in the midshaft (top row) and posterior and laterally where strains are highest under compressive load This study quantified the individual and combined longitudinal effects of PTH(1–34) and loading on the bone morphometric and densitometric properties in ovari...

The longitudinal effects of ovariectomy on the morphometric, densitometric and mechanical properties in the murine tibia: A comparison between two mouse strains

A thorough assessment of any prospective animal model of human disease is necessary before the substantial investment of resources into a preclinical study of potential therapies. Oestrogen-deficiency and related bone loss following ovariectomy is a common animal model of osteoporosis. In this study we quantified the effects of ovariectomy on the tibia bone morphometric, densi...

Prenatal growth map of the mouse knee joint by means of deformable registration technique

Methodological Pipeline Joint morphogenesis is the process of development of the joint that starts before the birth. It is important to study joint morphogenesis in order to understand how it is related to musculoskeletal diseases and to optimise related interventions. In several cases the interventions are tested on animal models and the mouse pre-natal model is typic...

Collaboration with NC3Rs to reduce animal testing

University of Sheffield's researchers are trying to find ways to reduce animal testing in preclinical trials by using computer models and medical imaging. One application of this technology, also known as in silico methods, is to study the effect of skeletal diseases such as osteoporosis and its treatments.Using in silico methods, researchers conducted a longitudinal study o...
