Abstract Background The knee joint is one of the most commonly injured joints in the body. Because of its complex structure, the joint is subjected to numerous pathologies and due to the recent increase in various sport activities; there has been a parallel increase in sport-induced internal derangements of the knee. Ultrasound is emerging as a viable imaging modality in the assessment of the musculoskeletal system lesions especially in experienced hands Objective To evaluate the role of high resolution dynamic ultrasonography as a diagnostic tool in the assessment of different causes of knee joint pain compared to MR imaging. Patients and Methods This study included 50 patients with painful knee joints as 32 females and 18 males, 16 patients had bilateral knee examination. Their ages ranged between 5-66 years. The cases was referred to a private radiological center, some of them referred to assess the knee joint pain by ultrasound as a fast and cheapest modality, yet most of the cases referred to evaluate the knee joint by MRI and the ultrasound was done as complementary study. Results Comparing between ultrasound and MRI in evaluation of painful knee joints, although the ultrasound has role in evaluation of bursal, synovial and peri-articular soft tissue lesions, the MRI is advised as a primary imaging tool for cruciates, meniscal and ligamentous lesions when clinically suspected. Conclusion Ultrasonography is a safe, cheap and efficient tool in the evaluation of the peri articular soft tissues with limited screening role at the internal knee joint cruciate / meniscal derangements as well as some bony lesions involving the bony cortex. It has no role in the intramedullary bony lesions. At this point, we concluded that ultrasonography has an important complementary role with MRI examination in the evaluation of the knee pain of different causes yet it is operator dependent and needs experience.

Hyaluronic acid (HA) has been a treatment modality for patients with knee osteoarthritis (OA) for many years now. Since HA was first introduced for the treatment of painful knee OA, much has been elucidated regarding both the etiology of this disease and the mechanisms by which HA may mitigate joint pain and tissue destruction. The objectives of this article are to (1) describe the etiology and pathophysiology of OA including both what is known about the genetics and biochemistry, (2) describe the role of HA on disease progression, (3) detail the antinociceptive and anti-inflammatory actions of HA in OA, and (4) present evidence of disease-modifying effects of HA in the preservation and restoration of the extracellular matrix. These data support that HA is not only just a simple device used for viscosupplementation but also a biologically active molecule that can affect the physiology of articular cartilage.

Objective The goal is to optimize the diagnosis of complications after thread implantation using high-resolution ultrasound (US).Material and Methods The study design included the formation of twelve sample comparison groups. Inclusion criteria for the group: women without evident somatic pathology after cosmetic implantation in various periods after the procedure. The difference between the groups was in the chemical composition of the material (L-lactic acid, polydiaxanone, copolymer of L-actide with ԑ-caprolactone, polypropylene, polyester fiber in a silicone sheath, metal), complaints (the presence of amyctic, the presence of overcorrection, the absence of complaints), the period of time after implantation (up to 6 months, from 6 to 12 months, more than a year). Then ultrasound was performed, 33 qualitative and 7 quantitative indicators were analyzed. The study involved 93 women aged 29 to 65 years after the thread implantation. The circulation period varied from 3 days to 20 years.Results An analysis of the relationship between quantitative and qualitative features revealed statistically significant connections between the presence of an acoustic shadow and threads of polylactic acid and polypropylene, the presence of reverberation, and the metal – gold (p < 0.0001). Relationships were established between polyester fibers in a silicone sheath with complaints of inflammation, the presence of edema during examination, perifocal edema around the thread during ultrasound (p < 0.0001). The difference was also found between the diameter of the thread in the group of patients examined up to 6 months and the group in the period 6–12 months after implantation (p < 0.0001), as well as the group up to 6 months and more than a year (p = 0.0033).Conclusion The presence of an acoustic shadow, a thread diameter of more than 1 mm are ultrasound signs of fibrotic changes around the thread. The characteristic echographic signs of inflammation around the thread will be a zone of reduced echoicity, corresponding to perifocal edema. Hypercorrection is a consequence of fibrotic changes development around the thread.

Background: The aging process results in changes in the musculoskeletal system causing a decrease in function of joints, loss of elasticity and limited mobility. This condition also causes joint pain, especially in the joints supporting the body weight, namely the knee. The previous studies discussed the method of reducing pain using a contras bath which was implemented by soaking parts of the body that experience pain alternately with hot and cold water, this was difficult to apply if the pain occurs in the upper body. Modifications in contrast baths using compresses to the knee joint have never been implemented before.Objective: This study aimed to figure out the effect of the contras bath method using compresses to reduce knee joint pain in the elderly.Method: The design of this study was pre-experimental with one group of pretest-posttest. The sample used was 16 elderly who were selected by random sampling at Posyandu (a center for pre- and postnatal health care and information for elderly) in village of Sawit Gantiwarno, Klaten. Contrast bath is applied by giving compresses of warm and cold water alternately with a ratio of three minutes: one minute per-day during 20 minutes, for a week. Pain measurement is performed using the Visual Analog Scale (VAS) instrument.Result: The mean of knee pain before giving a contrast bath was 5.44, whereas after a contrast bath was 3.50. Bivariate analysis used Wilcoxon, it showed p value <0.05 which means there was a significant difference in knee joint pain before and after contrast baths were applied.Conclusion: Administration of contrast bath can reduce knee joint pain in the elderly.

Background: It is well understood that distal femoral and proximal tibia scale is lower in case of the Asian than that of their western counterparts. Because of the Asian population's comparatively smaller structure and stature, many surgeons claim that imported implants may not be well fitted for Asian origin patients, mainly based on Western morphometry. It is very likely that an overweight section will be used in many Asian centres in most operations, resulting in low results of the procedure of the implant. For joint substitution of distal femur, careful positioning of fitted implants as well as balancing of underlying soft tissues is important. It is also important to use incredibly complex surgical procedures. To retain its usual functional motion spectrum, use of a suitable femoral part dimension is necessary. Furthermore, owing to a discrepancy between the size of the prosthesis and the bone, there could be a host of serious issues. Objectives: To calculate the anthropometric distal femur parameter and determine the distal femur variations on the right and left side of the morph metric measurement and to evaluate dimension of current TKA as related to Indian population. Methodology: This study included visiting the out patients Department of Orthopedics, at AVBRH in the age group 30-50 year during the period of June-2020 to April-2023 with sample size of 50 patients. Detailed history and clinical review will be taken, including age, sex, socio-economic background, type of employment. In all patients involved in the study in Orthopedic OPD, thorough radiological assessment of all the knee joints will be performed. The radiological test and various anthropometrics will include knee joint Simple X-ray and CT-Scan. Expected Results: We expect that from our results, anthropometric measurements of Indian population may differ from other literatures.

The knee joint is a complex structure that plays a significant role in the human lower limb for locomotion activities in daily living. However, we are still not quite there yet where we can replicate the functions of the knee bones and the attached ligaments to a significant degree of success. This paper presents the current trend in the development of knee joints based on bio-inspiration concepts and modern bio-inspired knee joints in the research field of prostheses, power-assist suits and mobile robots. The paper also reviews the existing literature to describe major turning points during the development of hardware and control systems associated with bio-inspired knee joints. The anatomy and biomechanics of the knee joint are initially presented. Then the latest bio-inspired knee joints developed within the last 10 years are briefly reviewed based on bone structure, muscle and ligament structure and control strategies. A leg exoskeleton is then introduced for enhancing the functionality of the human lower limb that lacks muscle power. The design consideration, novelty of the design and the working principle of the proposed knee joint are summarized. Furthermore, the simulation results and experimental results are also presented and analyzed. Finally, the paper concludes with design difficulties, design considerations and future directions on bio-inspired knee joint design. The aim of this paper is to be a starting point for researchers keen on understanding the developments throughout the years in the field of bio-inspired knee joints.

Aging is a process that will be experienced by humans according to the cycle of growth and development. Changes both physically and psychologically often cause disorders and health problems that must be resolved. Problems with the physical aspect of the elderly, one of which is a decrease in musculoskeletal function, especially in the joints, often manifest the appearance of joint pain. The presence of joint cartilage damage due to inflammation, as well as an increase in the load on the joints due to excess body weight (obesity) is other factors that often arise. The hip, lumbal, cervical and knee joints are the parts that support the body's weight, so they experience the most problems. The purpose of this study was to determine the correlation between obesity and the incidence of knee joint pain in the elderly. The design of the study was correlational analytic with a cross sectional approach. The sampling was purposive sampling with 50 respondents as the sample. The instrument used was an observation sheet to measure the respondent's obesity variable and to determine the presence of joint pain using an interview form. The measurement results were then processed and bivariate analysis was carried out using the chi square test. The results of the research analysis Showed the value of p = 0.004 and α = 0.05, this meant that p < 0.05, so there was a correlation between the level of obesity and the occurrence of joint pain. This was because not only age but also  increasing body weight cause joint paint.  The ability of the knee joint to support the body as a whole was getting heavier due to friction of the joint cartilage. From these studies, it can be concluded that in the elderly, excess body weight can affect to the ability of bones and joints and result in joint pain. The health workers should support the elderly so that the elderly avoid the stress.

Abstract Background The knee joint is one of the most commonly injured joints in the body. Because of its complex structure, this joint is subjected to numerous pathologies and due to the recent increase in various sport activities, there has been a parallel increase in sport-induced internal derangements of the knee. The main strength of knee MRI is the assessment of articular and Peri-articular diseases. The specific structures best suited for MRI assessment include tendons, muscles and ligaments, as well as peri-articular soft tissue masses. Objective The purpose of this study is to detect the accuracy of MR imaging as a diagnostic tool in the evaluation of different knee joint pathologies that cause anterior knee pain, with emphasis on some of their grades and types for better assessment. Methodology This study included 20 patients (6 female and 14 male). Their ages range between 10-60 years (average age 30 years). All presented by anterior knee pain and were referred to radiology department of Ain Shams University hospital or private centers for MRI examination after orthopedic consultation. Results 5% of the patients presented with anterior knee pain showed MRI evidence of patellar tendinopathy (66% below the age of 30 years and more in females). In all cases the hyperintense focal thickening was at the proximal third of the tendon, with the AP diameter of the patellar tendon greater than 8mm. In our results about 10% of the patients in the study sample, had MRI evidence of tear in the anterior horn of lateral knee meniscus with a female equal to male (50% females and 50% males). Cartilage injuries were detected in 5% of the study sample, showing male predominance (100% were male and 0% were female) with average age 32 years. All have a past history of trauma. Conclusion MRI is generally safe, accurate, and specific modality which has been proven to be the modality of choice in the diagnosis of different knee pathologies that cause anterior knee pain in different age groups. Also, it has a high specification in detecting the grades and types of some of these diseases.

The paper presents some important aspects related to the human liver, which is a real human body's plant, having essential roles in human life, especially in the preparation of the food necessary for the organism, in the production of the various essential substances necessary for the body and the basic chemical elements. At the same time, the human liver has the role of detoxifying the body, processing and eliminating toxic elements from ingested foods. The liver secretes various substances necessary for the human body. The more we keep this vital organ healthier, the more human body becomes free, healthier, younger and vigorous. The liver is probably the organ with the most diverse functions in the human body. After ingestion of food, they are processed along the digestive tract and degraded to nutrients that will reach all tissues and organs in the body. The liver is an annexe of the digestive tract with a very complex structure. The morphological unit of the liver is the liver lobe. It has a pyramid shape and a length of a few millimeters. The liver contains up to 100,000 lobules.

The knee joint is a complex biomechanical system, where the complexity of structure determines pathology variety, difficulties in treatment and rehabilitation. The conservative treatment possibilities of the ligamentous apparatus injuries of a knee are the subject of our discussion. Purpose of the study is to analyze the prevalence of knee traumatic injuries and modern ideas about the conservative treatment possibility of these injuries. Ligamentous apparatus injury of a knee joint is a common one, especially among athletes, with different mechanisms of knee injuries characteristic of different sports. Injuries of the lateral collateral ligament must be diagnosed in a timely manner in order to determine the possibilities of conservative and / or surgical treatment. Failure to recognize the injury details can lead instability and poor results to a knee after ligament reconstruction. Proponents of conservative treatment tactics provide evidence that non-operative treating of the ligaments also gives good results. The complex structure of a knee joint and a large number of variants of its damage impose a special responsibility on traumatologists-rehabilitologists, who are engaged in the restoration of its functions. The question of the choice between surgical restoration or conservative treatment of acute BCS injuries of knee joints remains open and depends on the specific situation, but in each case, rehabilitation measures are required, on the timeliness and adequacy of which the patient's quality of life will depend on.
