Aim. To reveal the influence of patient’s connective tissue state and body mass on the development of damage of the cartilaginous tissue of femoral bone medial condyle in case of medial meniscus rupture. Materials and methods. The study included 85 patients, undergoing arthroscopic treatment of the knee joint in connection with damaged medial meniscus. The damage degree of femoral medial condyle cartilaginous tissue was estimated using Outerbridge classification (1961). The body mass was calculated by the body mass index kg/m2. To assess the connective tissue elasticity, “the method of express diagnosis of dysplastic state of connective-tissue structures in conditions of ambulatory traumatologo-orthopedic service” was used. Results. The present paper is devoted to a widespread problem – the damage of femoral medial condyle cartilaginous tissue in case of medial meniscus rupture. The aim of the study was to find out the influence of connective tissue state and body mass on the damage of the femoral medial condyle cartilaginous tissue. Seventy patients were examined. As a result of analysis, it was established that an excess body mass as well as low connective tissue elasticity provoke destruction of the cartilaginous tissue of femoral bone medial condyle. Patients with connective tissue dysplasia are more tolerant to cartilaginous tissue degradation. The risk group for cartilaginous tissue damage includes persons with low connective tissue elasticity and obesity. Conclusions. When medial meniscus is ruptured, most patients during the first 6 months after trauma experience damage of femoral medial condyle cartilaginous tissue. The most favorable for the outcome is the state when patients have a normal body mass. Dysplastic state of connective tissue somehow eliminates the damaging factor at the expense of elevated elasticity of cartilaginous tissue. The most unfavorable is the situation, when patients have excess body mass and low connective tissue elasticity. For this group of patients the most optimal variant is hospitalization and arthroscopic treatment taking into account urgent indications.

Objective. To reveal the influence of functional mobility of connective-tissue structures on the development and course of intra-articular pathology of the knee joint. Materials and methods. Patients (n = 279) with intra-articular pathology of the knee joint after the arthroscopic treatment were examined. The state of functional mobility of connective-tissue structures was diagnosed using the express method for dysplastic state of connective tissues in conditions of ambulatory-polyclinic service. Statistical analysis was carried out with Pirson correlation criteria. Results. The paper is devoted to analysis of the influence of functional connective-tissue structure mobility on the development and course of intra-articular pathology of the knee joint. Subjects with low functional mobility of the connective-tissue structures were established to be more often subjected to chondromalacia of cartilaginous tissue of the femoral medial condyle and injury of the medial meniscus. Such pathology as slipping patella, Goff body hypertrophy and knee joint chondromatosis are typical for subjects with hypermobility of the connective-tissue structures. Conclusions. High degree of functional mobility of connective-tissue structures significantly contributes to preservation of cartilaginous cover of the femoral medial condyle, even with concomitant pathology of the knee joint available. For men with high functional mobility of connective-tissue structures, the most common diseases are knee joint chondromatosis and Goff body hypertrophy, and for women slipping patella. For women with low functional mobility of connective-tissue structures, the most typical is pathology of the medial meniscus.

Abstract Introduction. The aim of the study was to analyze effusion, bone edema, joint/articular cartilage, menisci and ligaments in correlation with pain intensity, sport activity and BMI. Methods. In our prospective study, 261 knee MRIs of patients with acute knee trauma were analyzed, who had a negative x-ray of the knee for fracture, and pain lasting for 1 month despite conservative therapy. Results. Gender distribution: 65.1% male and 34.87% female patients. Majority of subjects had body mass index from 18.5-24.9 (41.76%) The presence of an edema in the medial condyle of the femur was detected in 12.64% of patients. The most common lesion was lesion on the cartilage of the medial condyle on the femur (33.72%). We found lesions of the ACL in 40% of the cases. All patients with a combined trauma to the anterior cruciate ligament and the posterior horn of the medial meniscus had also a bone edema type 1 and type 2. Conclusion. Age and body weight do not have an impact on the cause of trauma and the type and grade of the knee lesions. Athletes and not athletes have signifycantly different causes of trauma to the knee. Patients with lesions in the posterior horn of the medial meniscus grade 3 had significantly more bone edemas (p=0.013). Localization of the pain is not linked to the cause of injury, but it depends on the developed lesions on the knee.

Annotation. Among the large joints, the knee joint is most often injured, which is due to the peculiarities of its structure and functional loads in the process of human life. The most common injuries are meniscus damages of the knee joint, that is the evidence of steady increase in the number of partial arthroscopic meniscectomies, which have become the most common orthopedic procedure. Diagnosis of meniscus damage is based on the results of clinical examination, sonography and MRI. Increasing the resolution of MRI machines, improving the technique of their implementation allows to improve the quality of diagnosis of meniscus ruptures and improve the results of surgical arthroscopic interventions on the knee joint. The aim of the study – to demonstrate the capabilities of high-intensity 1.5 Tesla MRI and to study the reliability of MRI signs of meniscus damage in comparison with the results of arthroscopic interventions in acute and chronic knee joint injury. The work is based on the results of MRI examinations and arthroscopic interventions of 247 patients with acute and chronic knee joint injuries aged 14 to 59 years. Medial meniscus damage was diagnosed in 206 (83.41%) patients. Lateral meniscus ruptures were diagnosed in 34 patients (13.76%). Simultaneous damage of both menisci was found in 7 (2.83%) patients. It was found that ruptures of the medial meniscus by location were: the root of the posterior horn of the medial meniscus in 4 (1.94%) patients, ruptures of the posterior horn in 82 (39.81%) patients. Injury of the posterior horn with the transition to the body of the meniscus was diagnosed in 117 (56.79%) patients. Anterior horn ruptures were detected in 3 (1.46%) patients. With ruptures of the lateral meniscus: damage of the root of the posterior horn of the lateral meniscus was found in 2 (5.88%) patients, damage of the posterior horn in 9 (26.47%) patients. Posterior horn rupture with transition to the body of the meniscus was diagnosed in 19 (55.89%) patients. Isolated ruptures of the anterior horn were found in 4 (11.76%) patients. Simultaneous damage to both menisci was found in 7 (2.83%) patients. 206 (83.40%) partial meniscectomies were performed during arthroscopic interventions and meniscus suturings were performed over 41 (16.60%) patients. In order to identify meniscus damage and their location during MRI knee joint investigations 21 pseudo-positive and 18 pseudo-negative cases of diagnosis were revealed. The sensitivity of MRI for defining damage and localization of meniscus rupture was 91,7%, specificity 92,6%, diagnostic accuracy 94,8%. Discrepancies in the evaluation of meniscal damage most often occurred in cases of their combined ruptures and degenerative changes in the menisci.

The results of morphological studies of auxiliary elements (patella, meniscus, cruciate ligament, synovial bags) of 60 knee joints of adult corpses, 30 of which were intact (without signs of deforming arthrosis) and 30 with signs of deforming arthrosis of stages III-IV are presented. It is established that the auxiliary apparatus undergoes significant changes in the progression of deforming arthrosis. In a greater degree degenerative changes prone articular cartilage of the patella and medial condyles of the knee joint. The affected areas were characterized by thinning of the articular cartilage or its complete absence, as well as the presence of osteophytes along the edges of the articular surfaces. The measurements of the relative length, width, and thickness of the meniscus also confirmed the fact of their substantial deformation and degeneration, mainly of the medial meniscus. The posterior part of the body and the horn of the medial meniscus were most susceptible to the destruction of the cartilaginous tissue and were accompanied by the erasure and disintegration of the inner margin. Synovial membranes with deforming arthrosis were thickened, compacted and locally hyperemic, had papillary growths, which indicates the presence of synovitis and fluid accumulation not only in the joint cavity but also in synovial bags, the sizes of which were significantly increased. Intra-articular ligaments are hyperemic, and fragments are noted. Pterygoid folds are enlarged, locally hyperemic, with a vascular pattern, elongated processes are visualized along the edges. Identified morphological changes in the progression of deforming arthrosis lead to trophic and metabolic disturbances of all structures of the knee joint. The results of the study of the auxiliary elements of the knee joint can be used as a control in the diagnosis of deforming arthrosis.

Background: Of the synovial joints in the body knee joint is the largest. Each meniscus is a piece of fibrocartilage with a thickened outside edge and a thin inner edge so that it is wedge-shaped in cross section. The purpose of the present study was to establish database on standard dimensions in knee menisci of adults of north Indian population.Methods: The sample for this study was collected from April, 2012 to June, 2013. For this study, 200 menisci (100 right and left each) of 50 adult humans were taken for analysis. Measurements were done with the help of non-elastic thread and digital vernier calipers. All dissections were performed in a systematic fashion.Results: The width of the lateral meniscus was significantly different form medial meniscus with lateral and medial menisci widest in middle and posterior third respectively. The middle one third of both lateral and middle menisci was the thickest.Conclusions: It is always good to have a set of anatomical morphometric parameters of the menisci like the width and thickness. The measurements of suitable grafts may provide a more acceptable meniscal replacement in the future.

Objectives: Proprioceptive sense plays important role of the protective reflex response against the harmful forces on the joint takes part in protection against the injuries. The load on the musculoskeletal system increases with higher body weights and joints become prone to injuries due to this increased load. The goal of this study was to investigate the relationship between the proprioceptive sense of the knee joint, mostly affected by loading, and the body weight, body mass index, and body fat ratio. Methods: 25 healthy people aged between 21 and 36 years included in the study. Body weights, body mass indexes (BMI), and body fat ratios of the individuals were measured. Proprioceptive sense in the knee joint is evaluated through the active joint position sense (A-JPS) assessments. The A-JPS of 50 knees of 25 individuals are evaluated at supine and load bea squat with 30° and 90° of knee flexion. To measure A-JPS, targeted angle were shown using goniometer and digital photography has been taken. Then they return to the initial position and repeat the angle and the second image was captured. After three times repetitions, deviations from 30° and 90° were called mean angle errors. The angle error measurements were performed with specifically written programme MATLAB (Computer Aided Design software). Pearson and Spearman Correlation Analyses were used for statistics. Results: There was no correlation between the body weight and the proprioceptive error at supine and squat for 30° and 90° flexion angles (p>0.05). When the individuals has been grouped according to their BMI values thinnesses for (BMI = 15-20 kg/m²), normals for (BMI = 20-25 kg/m²), and overweights for (BMI = 25-30 kg/m²) and the correlation between the BMI and proprioceptive error has been evaluated, there was no correlation for thinnesses and normals, for overweights at 90° squat position a medium strength positive correlation is observed (r=0.644, p=0.01). For thinnesses and normals there is no correlation between the body fat ratio and the proprioceptive error. For the overweights for 30° and 90° flexions at squat there is medium strength, strong positive correlations (r1=0.540, p=0.04; r2=0.709, p=0.005). Conclusion: Consequently, especially for individuals with high BMI, at load bearing squat position for 90° flexion, the proprioceptive sense decreases. Increased body fat ratio negatively affects the proprioception at load bearing squat position for 30° and 90° flexion angles. According to these results being overweight can be considered as an disadvantage in terms of proprioceptive sense.

Obesity has become one of the major health issues in India. WHO defines obesity as “A condition with excessive fat accumulation in the body to the extent that the health and wellbeing are adversely affected”. Obesity results from a complex interaction of genetic, behavioral, environmental and socioeconomic factors causing an imbalance in energy production and expenditure. Peak expiratory flow rate is the maximum rate of airflow that can be generated during forced expiratory manoeuvre starting from total lung capacity. The simplicity of the method is its main advantage. It is measured by using a standard Wright Peak Flow Meter or mini Wright Meter. The aim of the study is to see the effect of body mass index on Peak Expiratory Flow Rate values in young adults. The place of a study was done tertiary health care centre, in India for the period of 6 months. Study was performed on 80 subjects age group 20 -30 years, categorised as normal weight BMI =18.5 -24.99 kg/m2 and overweight BMI =25-29.99 kg/m2. There were 40 normal weight BMI (Group A) and 40 over weight BMI (Group B). BMI affects PEFR. Increase in BMI decreases PEFR. Early identification of risk individuals prior to the onset of disease is imperative in our developing country. Keywords: BMI, PEFR.
