Physical examination in the presence of a multiligament knee injury can be complex and challenging. Hence, stress radiography is a useful and inexpensive tool that is widely used in the assessment of this type of injury. It guarantees an objective analysis of the magnitude of knee instability, which may reduce the observer's interpretation bias in relation to the physical examination. However, for the radiographic analysis to be reproducible, it is necessary to standardize the technique to evaluate each of the main knee ligaments. This article aims to describe in detail how to perform stress radiography to assess the sufficiency of the posterior cruciate ligament and collateral ligaments in the context of a multiligament injury.

Introduction: Ischaemic heart disease (IHD) and cerebrovascular disease are leading causes of morbidity and mortality worldwide. Cerebral small vessel disease (CSVD) is a leading cause of dementia and stroke. While coronary small vessel disease (coronary microvascular dysfunction) causes microvascular angina and is associated with increased morbidity and mortality.

Background: Rheumatoid arthritis (RA) is a chronic autoimmune disease which afflicts about nearly 1% of global population. RA results in synovitis and cartilage/bone damage, even disability which aggravates the health burden. Many drugs are used to relieve RA, such as glucocorticoids (GCs), non-steroidal anti-inflammatory drugs (NSAIDs), and disease-modifying anti-rheumatic drugs (DMARDs) in the clinical treatment.

Stress echocardiography has evolved from the sole assessment of regional wall motion abnormalities (RWMAs) to the ABCDE protocol, as recommended by the recent clinical consensus statement from the European Association of Cardiovascular Imaging, reflecting the need for a more systematic patient assessment. Steps A, B, C, D, and E assess RWMAs, lung B-lines, left ventricular contractile reserve, coronary flow velocity reserve (CFVR) in mid-distal left anterior descending artery, and heart rate reserve, respectively. Impairment of CFVR is considered as the earliest abnormality in the ischaemic cascade.

Background And Purpose:  Early migration of the uncemented cruciate-sacrificing rotating platform ATTUNE and Low Contact Stress (LCS) tibial components was classified as at-risk for aseptic loosening rates exceeding 6.5% at 15 years based on recent fixation-specific migration thresholds. In this secondary report of a randomized controlled trial (RCT) we aimed to evaluate whether the 5-year migration, inducible displacement, and the clinical outcome of the ATTUNE components were comparable to those of the LCS.
