Introduction: Osteoarthritis is a progressive joint disease characterized by loss of articular cartilage, joint bone hypertrophy, subchondral sclerosis, and chemical and morphological alterations in the synovial membrane and joint capsule. Stiffness, soreness, and focused dislocation of the articular cartilage are changes in the disease seen at the last level of OA, as well as synovial inflammation. Pain is a common clinical symptom, especially after prolonged exercise and weight bearing, and stiffness occurs after inactivity. Biologic markers will also play an important role in the production and monitoring of new structure-modifying therapies for osteoarthritis due to their rapid changes in response to treatment. Aim: We conducted an observational study to estimate biochemical markers in the knee osteoarthritis patients who came to SMHRC Nagpur for a routine visit. Material and Methods: The study included 60 people who visited Shalinitai Meghe hospital in Nagpur for a health check-up. We were able to keep the two groups apart here. The control group is comprises of Healthy Volunteer, while the study group is made up Knee osteoarthritis patients. Each community consists of 30 patients. COMP, Endoglin, Osteopontin, Hs-CRP: all of these parameters were estimated by commercially available ELISA kit. Results: The levels of COMP, Endoglin, Osteopontin, and Hs-CRP in the study group were significantly higher than in the control group. In synovial fluid detection, endoglin levels in the sample group are not significantly higher than in the control group. Endoglin levels in the blood increase, as do other parameters. Conclusion: These findings show a significant increase in the systematic and local development of these biomarkers in the main OA of the knee, as well as the link between disease severity and its production, meaning that they may be involved in OA pathogenesis. Longitudinal studies with repetitive measurements of these biomarkers in plasma and synovial fluid and their interactions with knee pain OA are necessary to track or predict the clinical course of OA and, ultimately, determine their potential role in determining the best time to participate.

Introduction: Knee osteoarthritis (OA) is a weight-bearing joint disease and is more common in overweight and obese persons. The objective of this study was to determine the role of rehabilitation exercises (REs) of lower limbs on weight, functional strength, and exercise adherence in overweight and obese knee OA patients. Materials And Method: The patients were recruited from the Urban community of Lahore, Pakistan. The patients were divided into the rehabilitation group (RG) and control group (CG). The patients in the RG performed the REs of lower limbs and followed the instructions of daily care (IDC), while the patients in the CG only followed the IDC for 12 weeks. Outcome measures were assessed at pre-test before grouping and post-test after 12-weeks of interventions. The measures included: weight, functional strength, and exercise adherence. The Paired Samples t-test (for the normally distributed data) and the Wilcoxon Signed Ranked Test (for the data that was not normally distributed) were used to analyze the differences within groups from pre to post-test measurements. The analysis of variance 2 × 2 factors and the Mann-Whitney U-test were used to analyze the difference of weight and functional strength respectively between the groups. Results: The patients in the RG reported a statistically significant weight reduction (p < 0.001) and improvement in the functional strength (p < 0.001) within the group. Similarly, the patients in the CG also reported a significant improvement in the scores of functional strength (p = 0.004) within the group. The improvement in the scores of functional strength was greater in the patients of RG than the CG (p < 0.001. Similarly, the patients in the RG reported a statistically significant reduction in weight than the CG (p < 0.001). Conclusion: The REs could improve weight, functional strength and exercise adherence.

Introduction: Knee osteoarthritis (OA) is a weight-bearing joint disease and more common in the overweight and obese persons. The objective of the study was to assess the feasibility and acceptability of instructions of daily care (IDC) on pain, mobility and body mass index (BMI) among knee OA participants who are overweight or obese. Material and Method: The study was an open-label randomized controlled trial of six-weeks. Forty overweight and obese participants with knee OA were randomly divided into two groups by a computer-generated number. The participants in the Instruction Group (IG) were provided with leaflets explaining IDC for the duration of six-weeks. Both groups were instructed to take low doses of the non-steroid anti-inflammatory drug (NSAIDs) on alternate days. The outcome measures were pain, mobility and BMI. The feasibility and acceptability of knee pain and mobility were assessed using a questionnaire designed by experts in rehabilitation. Results: Participants in the IG reported more statistically significant pain relief as assessed by the Western Ontario and McMaster Universities Osteoarthritis Index score (p=0.001) and improvement in mobility (p=0.000) assessed by the Timed Up and Go test score after six weeks compared to the Control Group (CG). Both groups did not demonstrate any significant change in BMI (p-value > 0.05), The results of descriptive statistics showed a significantly higher satisfaction score to participants who received a combination of IDC and NSAIDs, indicating an acceptable intervention. Conclusion: The IDC are effective and acceptable in terms of improving pain and mobility and should be recommended as the usual care of treatment.

Background: Drug abuse is a social burden and a public health disorder. Previous evidence suggested numerous illicit substances (e.g., opioids, amphetamines, cocaine, & cannabis) affect immune system functions, oxidative stress mechanisms, inflammatory cytokines, and reactive oxygen species production. This study aimed to determine the extent of these metabolic parameters in opioid-dependent patients. We also compared these patients with a healthy control group. Methods: This study was conducted in Amirie Clinic, Kashan, Iran. Plasma and serum samples from 50 illicit opioid users (study group) and 50 non-opioid users (control group) were studied. Metabolic levels for MDA, NO, TAC, GSH, Insulin, HOMA-IR, and hs-CRP were assessed in both research groups (N=100). Results: There was a significant difference in the status of MDA (P=0.003), NO (P=0.01), TAC (P=0.003), GSH (P=0.001), insulin (P=0.04), HOMA-IR (P=0.02), and hs-CRP (P=0.001) between the study and control groups. Furthermore, there was a significant correlation among the duration of illicit opioid use and MDA concentrations (r=-0.424, P=0.002), as well as TAC levels (r=0.314, P=0.02). Conclusion: The study results suggested metabolic profiles were impaired in the study group, compared to the controls.

Background: Knee osteoarthritis (OA) has been linked to a chronic low-grade inflammatory response and altered metabolic activity of articular cartilage. Objective: The purpose of this investigation was to evaluate the effectiveness of a 12-week (3 times/week) lower body positive pressure (LBPP) treadmill walking regime on knee pain and systemic biomarkers of inflammation and cartilage degradation. Methods: Sixteen overweight (BMI > 25 kg/m2) knee OA patients were randomized to a LBPP treadmill walking exercise group (N = 7) or non-exercise control group (N = 9). Baseline and 12-week follow-up assessments evaluated the following dependent variables: acute knee pain during full weight bearing treadmill walking; inflammatory biomarkers (C-reactive protein, interleukin-1β, interleukin-6, s100A8/A9, and tumor necrosis factor-α), and catabolic metabolism of articular cartilage (sCOMP). Results: Knee pain at baseline and follow-up remained unchanged for the non-exercise control group (P > 0.05). However, knee pain for the LBPP exercise group was significantly decreased at follow-up (P ≤ 0.05). No differences in the biomarkers of inflammation and cartilage degradation were observed for between and within group comparisons (all P > 0.05). Conclusions: Data suggested that the LBPP supported walking regime could be effectively used to promote regular weight bearing exercise without exacerbation of knee joint pain and did not increase levels of systemic inflammation or catabolic activity of articular cartilage in overweight knee OA patients. This pilot investigation offers important insight regarding the potential role that the LBPP technology could play in facilitating investigations examining the disease modifying effect of exercise on knee OA pathogenesis.

Abstract Osteoarthritis (OA) is currently the most generic form of joint disease. It is a complex process in which degenerative changes occur in the articular cartilage [AC], subchondral bone, and synovial membrane and can lead to permanent joint failure. The primary and most commonly used method of diagnosing degenerative changes is classic radiography. Magnetic resonance imaging (MRI) may be used to assess the extent of damage to joint surfaces, but this method is limited by the availability of specialised equipment and the excessive cost of the examination. Arthroscopy, an invasive procedure, is considered the “gold standard” in joint diagnosis. The occurrence of degenerative changes is closely related to the friction and lubrication processes within the joint. The main causes of osteoarthritis are a change or lack of synovial fluid, deformation of the joint bones, local damage to the articular cartilage, and a change in the mechanical properties of the articular cartilage due to water loss from the damaged superficial layer. An alternative, non-invasive method that allows for a delicate assessment of the condition of moving joints is vibroarthrography (VAG). The analysis of vibroacoustic signals generated by moving joint surfaces has an immense potential in the non-invasive assessment of the degree of damage to articular cartilage, meniscus and ligaments and the general diagnosis of degenerative diseases. The purpose of this study is to analyse and statistically compare the basic characteristics of vibroacoustic signals recorded with a CM-01B contact microphone placed on the patella for motion in the 90°–0°–90° range in a closed kinetic chain (CKC) in a control group (HC) and a group of patients diagnosed with osteoarthritis (OA), qualified for the knee alloplasty.

Samples of articular cartilage of femur, tibia and patella of 15 dogs with experimentally induced degenerative joint disease (DJD) were microscopically analyzed. Animals were distributed into three groups (n=5): the control group received no medication; the second group was treated with chondroitin sulfate and the third received sodium hyaluronate. Samples were processed and stained with HE and toluidine blue for morphological evaluation. The metabolic and proliferative activity of the chondrocytes was evaluated by the measurement of nucleolar organizer regions (NORs) after impregnation by silver nitrate. Significant differences were not observed (P>0.05) in the morphology among the groups, however, the group treated with sodium hyaluronate had a higher score suggesting a trend to a greater severity of the lesions. Significant differences were not observed (P>0.05) in the measurement of NORs, cells and NORs/cells among the groups. Although differences were not significant, sodium hyaluronate group showed higher NOR and cell counts which suggested an increase of the proliferation rate of chondrocytes. In addition, a higher NOR/cell ratio in the group treated with chondroitin sulfate suggested that this drug may have stimulated the metabolic activity of the chondrocytes, minimizing the lesions resulting from DJD.

The aim of this study was to determine the anti-osteoarthritic effects of LI73014F2, which consists of Terminalia chebula fruit, Curcuma longa rhizome, and Boswellia serrata gum resin in a 2:1:2 ratio, in the monosodium iodoacetate (MIA)-induced osteoarthritis (OA) rat model. LI73014F2 was orally administered once per day for three weeks. Weight-bearing distribution and arthritis index (AI) were measured once per week to confirm the OA symptoms. Synovial membrane, proteoglycan layer, and cartilage damage were investigated by histological examination, while synovial fluid interleukin-1β level was analyzed using a commercial kit. Levels of pro-inflammatory mediators/cytokines and matrix metalloproteinases (MMPs) in the cartilage tissues were investigated to confirm the anti-osteoarthritic effects of LI73014F2. LI73014F2 significantly inhibited the MIA-induced increase in OA symptoms, synovial fluid cytokine, cartilage damage, and expression levels of pro-inflammatory mediators/cytokines and MMPs in the articular cartilage. These results suggest that LI73014F2 exerts anti-osteoarthritic effects by regulating inflammatory cytokines and MMPs in MIA-induced OA rats.

Endothelin-1, a potent vasoconstrictor regulator, contributes to articular cartilage destruction. Therefore, we aim to assess the correlation of endothelin-1 concentrations with the development and severity of knee osteoarthritis (OA). This study included a population of 209 patients with knee OA. Kellgren-Lawrence (KL) grading was utilized to score the severity of OA. The case group had higher serum endothelin-1 concentrations than controls. Patients with knee OA with a relatively higher grade showed significantly elevated serum and synovial fluid (SF) endothelin-1 concentrations compared with those with lower KL grades. A significant correlation was found between serum and SF endothelin-1 concentrations and KL grades. Serum and SF endothelin-1 concentrations are correlated with the development and progression of knee OA.

Introduction: The aim of this study was to assess effects of strength, stretching and balance home exercise program (moderate intensity, performed once a day, five times a week) on quality of life of people with knee osteoarthritis. Methods: Participants with knee osteoarthritis performed physical therapy for a period of two weeks at the Department for Physical Medicine and Rehabilitation. The study group (n=30) continued to perform exercise program at home while the control group (n=30) did not continue the exercise program. The participants in the study group performed strength, stretching and balance exercises of moderate intensity, once a day, five times a week, for a total of eight weeks. The Short Form-36 Health Questionnaire (SF-36) was used to examine the effects of exercise program. Results: There was no the difference between the average value of quality of life in all examined areas (physical functioning, role limitations due to physical problems, role limitations due to emotional problems, vitality/energy, mental health, social functioning, physical pain, perception of general health) at the beginning of the study between the study group and control group (p>0.05 in all eight areas). The difference between the average value of quality of life at the beginning and end of the study was statistically significantly higher in the study group compared to the control group (physical functioning p=0.0001; role limitations due to physical problems p=0.0001; role limitations due to emotional problems p=0.0001; vitality/energy p=0.0001; mental health p=0.0001; social functioning p=0.0001; bodily pain p=0.0001; perception of general health p=0.0001). Conclusion: Home exercise program consisting of strength, stretching and balance exercises, of moderate intensity, performed once a day, five times a week is effective in improving quality of life of people with knee osteoarthritis.
