Functional results of surgical reconstruction of the anterior cruciate ligament of the knee joint in combination with lateral stabilization

The objective was to compare the effectiveness of isolated anatomical antegrade reconstruction of the anterior cruciate ligament (ACL) with bonetendon-bone autograft (BTB autograft) and in combination with lateral extra-articular tenodesis (LEAT) graft from the iliotibial tract (ITT).Material and methods. We analyzed 187 arthroscopic ACL reconstructions in patients with a Pivot shift test – 3+ degree. We performed an isolated ACL-R in 118 (63.1 %) patients in group 1 and added the LEAT from ITB to it in group 2.Results. According to IKDC-2000: 176 (94.1 %) patients were included in categories A and B, 11 (5.9 %) – in C. Significant differences in these groups appeared 15 months after the operation. According to KOSS: in group 2, the anterior and rotational knee stability, as well as the level of sports activity were higher, and pathological symptoms were less common.Conclusion. LEAT from ITB increases stability and functionality of the knee joint in patients with anatomical antegrade ACL reconstructions with BTB-autograft for terms over 15 months after the operation, and is an economically procedure

The total hip arthroplasty in the elderly with coxarthrosis

From 2001 to 2015 yrs 179 patients with hip joint pathology aged 65 years and older were treated in the Scientific Clinical Center of Gerontology, in the departments of orthopedics and traumatology of Moscow clinical hospitals № 12 and 31. Clinical data show that total hip arthroplasty can be successfully used in the treatment of degenerative and dystrophic diseases of the hip in the elderly. Objective assessments of somatic status, correction of comorbidities, preoperative planning, precise surgery technique, as well as early activation of the patient minimize the risks of surgery. The results of this treatment in a period of 6 months up to 3 years were excellent in 58.6% of cases, good - in 34.6%, satisfactory - in 3.9%, unsatisfactory - in 2.9%

Interaction of physical fields with nanostructured materials

Research results of several important material systems presented in this collective monograph demonstrate a number of characteristic features and unique effects. The main findings are listed below. 1. The interaction between molecules and semiconductor structures allows a new amplification effect to be registered and studied by utilizing a new parameter – characteristic time constant, which is extremely sensitive for the characterization of biomolecular quantity. 2. The effects of the interaction of magnetic, optical and electromagnetic fields with nanostructured composites, semiconductor structures, anisotropic media, magnetic fluid systems, layered structures, phonons of molecular nanocomplexes and nanoinhomogeneities of rough surfaces were established. 3. The fundamental nature of the interaction effects was found as a result of a careful comparison of modeling results with experimental data. The importance of the studies is underlined by the wide range of potential applications. For the reader’s convenience, the presentation of the material is structured as follows. The general content includes only the names of sections. The full content of each section is listed in the text. For the same reason, the list of references is given at the end of each section. The authors present the material in such a way that the reader can easily view the current state of research in these areas and be able to navigate freely in the text. Section 1 presents a number of effects registered in semiconductor structures with dielectric coatings as surface potential sensors. In particular, the effects of internal amplification in semiconductor (bio)sensors using single trap phenomena are revealed. The noise characteristics of semiconductor nanoscale sensor structures, the effect of γ-radiation on the noise and transport characteristics of the sensors mentioned above were analyzed. It is demonstrated that effects related to single traps can be used for the detection of troponin biomolecules as indicators of [...
