Comparative assessment of arthroscopic and ultrasound examination data were performed in 393 patients (400 knee joints). For the perfection of diagnosis quality a principle of “feedback” (cooperation) between examiners was used. Basing on the analysis of the achieved results the reasons for sonographic and ultrasound results (objective and subjective) incompatibility were determined and real diagnostic value of ultrasound examination was estimated for every intraarticular knee structure separately.

Goal. Consider the management of patients with effort thrombosis (Paget-Schretter syndrome).The article presents the modern vision of the problem of effort thrombosis. This review is aimed at describing the epidemiology, pathophysiology, diagnosis and treatment of patients with Paget-Schretter syndrome. SPS occurs spontaneously, as a rule, in young, healthy and active patients aged 20-30 years after strenuous physical activity. The ratio of men and women is 2:1, recently there has been a growing trend among women. The main complaints of patients with SPS include swelling of the affected limb, discomfort when moving the affected arm, pain and heaviness when trying to raise the arm up. When examining these patients, attention is paid to hyperemia of the skin or their cyanotic nature, pasty limbs, as well as an enhanced venous pattern on the shoulder, the so-called Arshel sign. The diagnosis is based on the data of anamnesis, physical examination, the “gold standard of diagnostics” – ultrasound examination of veins, the sensitivity and specificity of which is 70-100%. The first step in the diagnosis can be the evaluation of the D-dimer, with its negative values, the SPSH is rejected. With an obvious clinic and controversial results of serial ultrasound examinations, other imaging methods are used, such as computed contrast tomography, magnetic resonance imaging, the diagnostic value of which is especially significant in occlusive venous thrombosis.SPS differs not only from DVT of the lower extremities, but also from secondary DVT of the upper extremities, which determines the peculiarities of management of this category of patients, including surgical treatment aimed at preventing subclavian vein compression in the future. The article summarizes the experience in the management of patients with blood thrombosis.

The risk of knee injuries in freestyle skiing athletes that perform aerials is high. The internal stresses in the knee joints of these athletes cannot easily be directly measured. In order to ascertain the mechanical response of knee joints during the landing phase, and to explore the mechanism of damage to the cartilage and ligaments, a finite element model of the knee joint was established. Three successful landing conditions (neutral, backward, or forward landing) from a triple kicker were analyzed. The results demonstrate that the risk of cruciate ligament damage during a neutral landing was lowest. A forward landing carried medium risk, while backward landing was of highest risk. Backward and forward landing carried risk of injury to the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL), respectively. The magnitude of stress on the meniscus and cartilage varied for all three landing scenarios. Stress was largest during neutral landing and least in backward landing, while forward landing resulted in a medium level of stress. The results also provide the basis for training that is scientifically robust so as to reduce the risk of injury and assist in the development of a professional knee joint protector.

Background. The aim of the study was to assess the outcomes of surgical treatment of complex knee injuries with a posterior inverted-L approach to the knee joint. Material and methods. The study retrospectively enrolled 13 patients who underwent surgical treatment due to knee injuries with posterior tibial plateau fractures in 2015-2017. Pre-operative planning was based on antero­po­sterior and lateral X-rays and CT images. The fracture was assessed according to Luo’s three-column classification. Radiographic postoperative assessment was based on lower limb (standing) X-rays and measurements of the MPTA, aPPTA, JLCA, and aFaT angles in the operated and healthy limbs. Clinical assessment was based on the IKDC, KOOS, and Tegner-Lysholm Knee Scoring Scale. Results. Mean follow-up duration was 11.5 months (4-25 months). Anatomical joint surface reduction was achiev­ed in 12 patients and bone union was present in all patients. A posterior inverted-L approach was used in 9 pa­tients and combined approaches in 8 patients. According to the three-column classification, single-column fractures were found in 3 patients, two-column fractures in 4, and three-column fractures in 6 patients. The KOOS was 82%, the IKDC score was 80%, and the Tegner-Lysholm score was 82 points. Radiographic assessments of the operated knee joints showed an MPTA of 88.64 degrees, aPPTA of 79.78 degrees, JLCA of 0.8 degrees, and aFaT of 7.9 degrees. Conclusions. 1. Anatomical reduction and stable fixation of posterior plateau fractures of the proximal tibia are crucial in fracture management. 2. A posterior inverted-L approach is very useful when treating posterior tibial plateau fractures.

The purpose of this study is to explore whether shear wave elastography has diagnostic value in distinguishing benign and malignant thyroid imaging report and data system (TI-RADS) nodules, so as to provide more accurate information for clinical diagnosis and treatment of thyroid nodules. In this study, 134 patients with thyroid nodules who underwent ultrasound examination from February 2018 to October 2018 are collected. Firstly, according to the diagnostic criteria proposed by Horvath, TI-RADS grading is performed on them, and 78 patients with TI-RADS4 single solid nodules are screened out. Secondly, conventional ultrasound examination is performed on all the researchers, and shear wave elastographies are obtained 1 week after the examination. Thirdly, parameters of each lesion are measured by ultrasound physicians, and the maximum, minimum and average values of Young's modulus of each lesion are recorded. The results show that the mean and maximum of Young's modulus of benign lesions are (26.31 ± 9.88) kPa and (51.36 ± 14.51) kPa, respectively, the mean and maximum of Young's modulus of malignant lesions are (48.36 ± 16.53) and (69.15 ± 19.98) kPa, respectively, and the area under the ROC curve of Emean and Emax is 0.852 and 0.748, respectively. Therefore, shear wave elastography is a new type of ultrasound elastography, which has the advantages of objectivity and little influence from operators without artificial pressure. It has high sensitivity, specificity and accuracy in diagnosing benign and malignant thyroid nodules. Among them, the average value of Young's modulus has the greatest diagnostic value.

Joint Biomechanics

The knee joint, as the main lower limb motor joint, is the most vulnerable and susceptible joint. The knee injuries considerably impact the normal living ability and mental health of patients. Understanding the biomechanics of a normal and diseased knee joint is in urgent need for designing knee assistive devices and optimizing a rehabilitation exercise program. In this paper, we systematically searched electronic databases (from 2000 to November 2019) including ScienceDirect, Web of Science, PubMed, Google Scholar, and IEEE/IET Electronic Library for potentially relevant articles. After duplicates were removed and inclusion criteria applied to the titles, abstracts, and full text, 138 articles remained for review. The selected articles were divided into two groups to be analyzed. Firstly, the real movement of a normal knee joint and the normal knee biomechanics of four kinds of daily motions in the sagittal and coronal planes, which include normal walking, running, stair climbing, and sit-to-stand, were discussed and analyzed. Secondly, an overview of the current knowledge on the movement biomechanical effects of common knee musculoskeletal disorders and knee neurological disorders were provided. Finally, a discussion of the existing problems in the current studies and some recommendation for future research were presented. In general, this review reveals that there is no clear assessment about the biomechanics of normal and diseased knee joints at the current state of the art. The biomechanics properties could be significantly affected by knee musculoskeletal or neurological disorders. Deeper understanding of the biomechanics of the normal and diseased knee joint will still be an urgent need in the future.

This review focused on ultrasound examination of lungs, a useful complement to transthoracic echocardiography (EchoCG), which is superior to chest X-ray in the diagnostic value. The lung acoustic window always remains open and allows obtaining high-quality images in most cases. For a cardiologist, the major points of the method application are determination of pleural effusion and lung congestion. This method has a number of advantages: it is time-saving; cost-effective; portable and accessible; can be used in a real-time mode; not associated with radiation; reproducible; and highly informative. The ultrasound finding of wet lungs would indicate threatening, acute cardiac decompensation long before appearance of clinical, auscultative, and radiological signs of lung congestion. Modern EchoCG should include examination of the heart and lungs as a part of a single, integrative ultrasound examination.
