This review briefly summarises some of the definitive
studies of articular cartilage by microscopic MRI (µMRI) that were
conducted with the highest spatial resolutions. The article has
four major sections. The first section introduces the cartilage
tissue, MRI and µMRI, and the concept of image contrast in MRI.
The second section describes the characteristic profiles of three
relaxation times (T. 1. , T. 2. and T. 1ρ. )
and self-diffusion in healthy articular cartilage. The third section
discusses several factors that can influence the visualisation of
articular cartilage and the detection of cartilage lesion by MRI
and µMRI. These factors include image resolution, image analysis
strategies, visualisation of the total tissue, topographical variations
of the tissue properties, surface fibril ambiguity, deformation
of the articular cartilage, and cartilage lesion. The final section
justifies the values of
Degenerative disc disease (DDD) and osteoarthritis (OA) are relatively frequent causes of disability amongst the elderly; they constitute serious socioeconomic costs and significantly impair quality of life. Previous studies to date have found that aggrecan variable number of tandem repeats (VNTR) contributes both to DDD and OA. However, current data are not consistent across studies. The purpose of this study was to evaluate systematically the relationship between aggrecan VNTR, and DDD and/or OA. This study used a highly sensitive search strategy to identify all published studies related to the relationship between aggrecan VNTR and both DDD and OA in multiple databases from January 1996 to December 2016. All identified studies were systematically evaluated using specific inclusion and exclusion criteria. Cochrane methodology was also applied to the results of this study.Objectives

Trauma and orthopaedics is the largest of the
surgical specialties and yet attracts a disproportionately small
fraction of available national and international funding for health
research. With the burden of musculoskeletal disease increasing,
high-quality research is required to improve the evidence base for
orthopaedic practice. Using the current research landscape in the
United Kingdom as an example, but also addressing the international
perspective, we highlight the issues surrounding poor levels of
research funding in trauma and orthopaedics and indicate avenues
for improving the impact and success of surgical musculoskeletal
research. Cite this article:
We aimed to examine the characteristics of deep venous flow in
the leg in a cast and the effects of a wearable neuromuscular stimulator
(geko; FirstKind Ltd) and also to explore the participants’ tolerance
of the stimulator. This is an open-label physiological study on ten healthy volunteers.
Duplex ultrasonography of the superficial femoral vein measured
normal flow and cross-sectional area in the standing and supine
positions (with the lower limb initially horizontal and then elevated).
Flow measurements were repeated during activation of the geko stimulator
placed over the peroneal nerve. The process was repeated after the
application of a below-knee cast. Participants evaluated discomfort
using a questionnaire (verbal rating score) and a scoring index
(visual analogue scale).Objectives
