BACKGROUND: Anterior cruciate ligaments (ACL) injuries represent a major risk factor for early osteoarthritis (OA). PURPOSE: To evaluate the prevalence and 4-year progression of knee OA measured with 3T MR-imaging in individuals with ruptured, reconstructed or normal ACL and to assess the impact of thigh muscle characteristics. METHODS: A total of 54 knees (23/54 male, 31/54 female) were recruited from the Osteoarthritis Initiative (OAI). At baseline, 15/54 subjects had prevalent ACL ruptures and 15/54 subjects had prevalent ACL reconstruction (24/54 normal ACL)...

We describe the case of a young man with repeated hospital presentations for a variety of symptoms related to excessive bodybuilding and associated behaviours. He presented to our department (radiology) with right arm pain and loss of function. Ultrasound showed complete triceps rupture, rare in young patients and multiple cystic areas within the muscles of the arm. MRI revealed these to be multiple proteinaceous lesions within the muscle bellies and the possibility of self-innoculation was raised by the reporting radiologist...

BACKGROUND: High-voltage electric injury may induce lesion in different organs. In addition to the local tissue damage, electrical injuries may lead to neurological deficits, musculoskeletal damage, and cardiovascular injury. Severe vascular damage may occur making the blood vessels involved prone to thrombosis and spontaneous rupture. CASE DESCRIPTION: Here, we present the case of a 39-year-old male who suffered an electrical burn with high tension wire causing intracranial bleeding...

A 29-year-old man experienced right shoulder pain and weakness following a forced abduction and external rotation motion performed during an Australian football game. The following morning, the sports medicine physician referred the player for magnetic resonance imaging to exclude infraspinatus rupture, given the external rotation strength deficit. Magnetic resonance imaging revealed a low-grade partial tear of the medial infraspinatus muscle. J Orthop Sports Phys Ther 2016;46(12):1087. doi:10.2519/jospt.2016...

Rupture of the proximal tendon enthesis of the hamstring muscle (ICM) accounts for approximately 10% of all injuries of the ICM. It occurs most commonly in athletes and active middle-aged individuals. The complete rupture of all three tendons in active patients is generally seen as an indication for surgical repair of the tendon enthesis; however, the correct diagnosis is often not reached in a timely manner. This can lead to prolonged symptoms with pain, weakness and neuralgia. Operative treatment consists of anchor repair of the tendons resulting in good clinical outcome in several case series...

Profunda femoris artery aneurysms (PFAA) are very rare and easily overlooked because located deeply within thigh muscle. PFAAs have a high rate of rupture in comparison with other peripheral arterial aneurysms, resulting in emergency surgical procedures with significant morbidity. PFAAs is diagnosed with color arterial Doppler ultrasound, although computed tomography angiography (CTA) remains the best imaging method to precisely define the exact site and length of arterial involvement. PFAAs should be treated surgically once diagnosed, even if they are asymptomatic due to the high incidence of complications...

OBJECTIVES: The aim of this study was to identify histological features that correlate with terms commonly used to describe optical coherence tomographic (OCT) and optical frequency-domain imaging (OFDI) images of stented vessels, by means of a histopathological validation study using stented human coronary arteries. BACKGROUND: OCT imaging and OFDI are used to evaluate vascular responses to stent implantation. Descriptive terms such as "peristrut low attenuation" and "heterogeneous" have been used to describe neointimal characteristics that may have clinical relevance...

OBJECTIVE/BACKGROUND: Abdominal aortic aneurysm (AAA) is characterised by the infiltration of smooth muscle cell (SMC) apoptosis, inflammatory cells, neovascularisation, and degradation of the extracellular matrix. Previous work has shown that endoplasmic reticulum (ER) stress and SMC apoptosis were increased both in a mouse model and human thoracic aortic aneurysm. However, whether the ER stress is activated in AAA formation and whether suppressing ER stress attenuates AAA is unknown...

: Arresting or regressing growth of abdominal aortic aneurysms (AAAs), localized expansions of the abdominal aorta are contingent on inhibiting chronically overexpressed matrix metalloproteases (MMPs)-2 and -9 that disrupt elastic matrix within the aortic wall, concurrent with providing a stimulus to augmenting inherently poor auto-regeneration of these matrix structures. In a recent study we demonstrated that localized, controlled and sustained delivery of doxycycline (DOX; a tetracycline-based antibiotic) from poly(lactic-co-glycolic acid) nanoparticles (PLGA NPs), enhances elastic matrix deposition and MMP-inhibition at a fraction of the therapeutically effective oral dose...

Tendon rupture in dogs is generally the result of a direct trauma. This report described the use of adjacent muscle autogenic fascial graft for reconstruction of distal rupture of long digital extensor tendon in a dog. A two-year-old male mix breed dog, was presented with a non-weight bearing lameness of the right hind limb and a deep rupture of lateral side of right tarsus. History taking revealed that this rupture appeared without any apparent cause, when walking around the farm, three days before. Radiography was done and no fracture was observed...

Injury of the medial head of the gastrocnemius, also called "tennis leg," is known to heal uneventfully in most cases with compression and immobilization therapy. Failure to heal or long-term complications, including ongoing pain and pes equinus, have been documented in only a limited number of case reports. To the best of our knowledge, a severe concomitant contracture of the knee and ankle joint as a consequence of a maltreated gastrocnemius muscle rupture has not been previously reported in English-language reports...

AIMS: Processes in the development of atherosclerotic lesions can lead to plaque rupture or erosion, which can in turn elicit myocardial infarction or ischaemic stroke. The aims of this study were to determine whether Toll-like receptor 7 (TLR7) gene expression levels influence patient outcome and to explore the mechanisms linked to TLR7 expression in atherosclerosis. METHODS AND RESULTS: Atherosclerotic plaques were removed by carotid endarterectomy (CEA) and subjected to gene array expression analysis (n=123)...

Chronic proteolytic disruption of elastic fibers within the abdominal aortic wall results in wall vessel expansion to form rupture-prone abdominal aortic aneurysms (AAA). Arresting AAA growth is not possible since adult vascular smooth muscle cells (SMCs) poorly auto-regenerate and repair elastic fibers. Thus, there is a need to identify alternate cell sources capable of robust elastic matrix assembly to overcome elastolysis in the AAA wall. Previously, we demonstrated the superior elastogenic properties of rat bone marrow mesenchymal stem cell (BM-MSC)-derived SMCs (BM-SMCs) relative to aneurysmal and healthy rat aortic SMCs...

Second anterior cruciate ligament rupture is a common and devastating injury among young women who return to sport after ACL reconstruction, but it is inadequately understood. The purpose of this study was to compare gait biomechanics and return-to-sport time frames in a matched cohort of young female athletes who, after primary ACLR, returned to sport without re-injury or sustained a second ACL injury. Approximately 6 months after primary reconstruction, 14 young women (age 16 ± 2 years) involved in jumping, cutting, and pivoting sports underwent motion analysis testing after physical therapy and impairment resolution...
