Background:Knee osteoarthritis is more common in patients with type-2 diabetes mellitus, however it is not known whether this effect is caused by diabetes itself or concominant abdominal obesity. Objectives:The aim of this study is to determine whether type-2 diabetes itself, independent of abdominal obesity, is a risk factor for femoral cartilage, knee osteoarthritis and poor quality of life. Design:A cross-sectional design. Settings:Training and research hospital in Turkey. Patients and Methods:Female patients was enrolled in this study and divided into two groups: according to presence or absence of diabetes. Later, both the patients with and without abdominal obesity was divided into two groups according the presence of diabetes. Main Outcome measures:Clinical parameters were visual analog-scale, gait speed and short form-36. Knee radiographs were evaluated according to Kellgren Lawrance-Scale. And ultrasonography parameters were the measurements of distal femoral cartilage thickness. Sample size:126
The goal of this study is to evaluate a telehealth Stepped Exercise Program for Knee OsteoArthritis (STEP-KOA) among rural veterans. Methods: This is a single arm, pre-post pilot trial of the 6-month STEP-KOA program among rural Veterans with a physician diagnosis of knee OA who self-report knee pain ≥3 on a 0-10 scale and self-reported difficulty with either walking or stair climbing. We aim to enroll 20 Veterans in this project but may enroll up to 30 in order to obtain sufficient information to evaluate the program, particularly among Veterans who live in very rural areas. Assessments will be conducted via a combination of telephone and video at baseline and 2-, 4-, and 6-month follow-up. Assessments will include questionnaires related to pain, function and physical activity, as well as several physical performance tests. STEP-KOA begins with a low cost, primarily self-directed exercise program (supported by an internet-based tool; Step 1). Patients are then assessed for degree of improvement in symptoms, and then can step up sequentially to telephone or video-based physical activity coaching (Step 2) and physical therapy (Step 3) if they do not make clinically relevant improvements in prior steps. For this project, patients will be assessed approximately every 2 months to determine step progression. Participants will advance to the next step if they do not meet response criteria for pain and function established by the Outcome Measures in Rheumatology group and the Osteoarthritis Research Society International (OMERACT-OARSI). The Step 2 intervention involves bi-weekly telephone or video calls. Step 3 involves 3 telehealth PT visits, based on standard care for knee OA.
Higher aerobic capacity before surgery, as indicated during submaximal exercise testing by the oxygen uptake (VO2) at the ventilatory anaerobic threshold (VAT), is assumed to be prognostic for a better and faster postoperative recovery in patients with knee osteoarthritis (OA) undergoing total knee arthroplasty (TKA). Cardiopulmonary exercise testing (CPET) is the gold standard to measure aerobic capacity; however, it is unclear whether it is feasible to perform CPET using cycle ergometry in patients with knee OA prior to TKA surgery. The hypothesis is that performing CPET is feasible and participants will meet the feasibility criteria for success. The primary objective of this cross-sectional feasibility study is to investigate the feasibility of CPET in patients with knee OA three to six weeks prior to TKA surgery in three domains: a) recruitment rate of participants who are representative of the target study population; b) reaching the VAT during CPET; and c) acceptability and suitability. The secondary objective is to investigate aerobic capacity of the study population and to compare values with normative values. The study population consists of patients with knee OA scheduled for primary unilateral TKA surgery. Feasibility of CPET will be assessed against five criteria: 1) recruitment rate ≥20%; 2) CPET performance rate ≥90%; 3) ≥90% of participants reached the VAT; 4) no serious adverse events; and 5) ≥80% of participants had a positive attitude towards CPET. Aerobic capacity is determined by the VO2 at the VAT and the oxygen uptake efficiency slope (OUES). CPET is considered a safe procedure. Participants perform the CPET instead of a walking test following the standard preoperative screening and complete a questionnaire to examine their experiences. The investigator will contact the participants one week after the CPET to inquire whether they have developed any complaints afterwards. Benefit from participation is that all patients objectively get insight in their preoperative aerobic capacity.
This study will evaluate safety, tolerability, pharmacokinetics and immunogenicity of MEDI7352 in healthy participants.
Symptomatic knee osteoarthritis (OA) is the most common joint disorder in the U.S. and a leading cause of disability. Increasing age, obesity, and previous injury increase the lifetime risk of knee OA, but these factors are also independently associated with increased cellular senescence. Senescent cells accumulate in many tissues and contribute to chronic pathologies, linked to the secretion of pro-inflammatory factors collectively known as the senescence-associated secretory phenotype. In OA, senescent cells promote production of cytokines, chemokines, and matrix-degrading enzymes involved in progressive cartilage breakdown. The senolytic supplement fisetin alters the inflammatory and catabolic cartilage responses, which may clinically lessen OA pain while also slowing progressive cartilage breakdown. The purpose of this double-blind, randomized clinical trial is to compare 2 fisetin dosing regimens versus placebo. Sixty patients with mild to moderate knee OA will be assessed at baseline and 3 months in an effort to: determine if 2 different fisetin dosing regimens lessen pain and functional impairment compared to placebo, compare progressive changes in senescent cell activity and biomarkers of cartilage degradation between different fisetin dosing regimens and placebo, and assess acceptability and feasibility of 2 fisetin dosing regimens.
The functional outcome and longevity of total knee arthroplasty (TKA) is still a concern. Despite various developments in TKA designs, including fixed or mobile bearing, cruciate retaining or posterior stabilized, multi or single radius, it remains unclear which design is superior for achieving a physiological kinematic. In normal healthy knees the medial and lateral tibial condyles are different: the medial is almost flat while the lateral is somewhat convex. Thus, the movement during flexion is asymmetric: during the flexion, the medial condyle is stable throughout the range of motion while the lateral condyle slides anteroposteriorly with respect to femur). Therefore, the native knee requires a specific degree of rollback of the lateral compartment coupled with a medial pivot, which leads to an external axial rotation of the femur. This rollback is thought to be even more pronounced with increasing knee flexion angles to enable deep flexion without excessive shear forces acting at the patella or overloading the extensor mechanism. In addition, stability throughout flexion is a crucial element to normal knee function. Most TKA designs removal of the ACL, and the PCL in posterior-stabilized design, but the TKA do not fully restore the function of those ligaments. Based on this philosophy, the medial pivot TKA was designed to provide better function, patient satisfaction and increased survival. The objective of this study is to analyze whether the medial pivot design provides better outcome and prosthesis survival than conventional total knee arthroplasty.
Knee osteoarthritis has been ranked 11th highest contributor to non-fatal burdens in the world. Many research studies have discussed the relationship of hip muscle with knee joint stating that impaired hip strength can be a reason for knee pain. Furthermore, mobilization has been shown to be helpful in reducing pain, increasing range of motion and physical function in Osteoarthritis. Despite the evidence, there are very few studies that actually conducted clinical trials to test the effectiveness of mobilizations and strengthening of hip muscles in knee Osteoarthritis. Therefore our aim is to evaluate the effectiveness of hip joint mobilizations and strength training in knee osteoarthritis. OBJECTIVE: To determine the effects of hip joint mobilizations and strengthening exercises, on pain, physical function and dynamic balance in patients with knee osteoarthritis (OA) using Visual analog scale, Knee injury and Osteoarthritis Outcome Score and four square step test. METHODOLOGY: A randomized control trial will be conducted on 66 subjects with knee osteoarthritis and age 50 years will be enrolled in this study after screening by referring consultants. This study will be carried out at Physiotherapy OPD of DUHS, Civil hospital Karachi and Rabia Moon Memorial Institute of Neurosciences Trust. Subjects will be assessed at baseline and after 18 sessions using Visual analog scale, Knee injury and Osteoarthritis Outcome Score and square step test for pain, physical functioning and dynamic balance respectively. The subjects will be allocated into three groups through simple random sampling. Group A (joint mobilization group) will receive hip mobilization techniques, hip strengthening exercises along with the best available knee exercises while group B (hip muscles strengthening group) will receive hip-strengthening exercises with the best available knee exercises. Group C (knee strengthening group) will be receiving the best available knee treatment including exercises only. Patients will receive a total of 18 sessions, 5 treatment sessions per week for four successive weeks. The data will be entered and analyzed using SPPS version 21. Repeated mean one way ANOVA will be applied to measure VAS and KOOS scores within the group, for pairwise comparison between groups, Tukey's test will be applied. Chi-square will be applied for FSST scoring. A P-Value less than 0.5 will be considered significant.
metformin alleviates drug-induced osteoarthritis (OA)-like change in mice knee joint through activating autophagy and downregulating apoptosis. Metformin exerts its protective effects against OA through the AMPKa2/ SIRT1 pathway. Metformin suppresses IL-1β-induced oxidative and osteoarthritis-like inflammatory changes by enhancing the SIRT3/PINK1/Parkin signaling pathway, thereby indicating metformin's potential in prevention and treatment of osteoarthritic joint disease.
The aim of the present investigation is to evaluate the efficacy of Mangoselect®, a mangosteen extract, and of a formulation containing Mangoselect®, in subjects suffering from activity/exercise-induced knee joint pain/discomfort, during a 12-week supplementation period. Subjective discomfort improvement will be assessed with both WOMAC questionnaire and pain Visual Analogic Scale (VAS); functional joints features, quality of life, and inflammatory markers, will also be assessed. Finally, long lasting benefits will additionally be evaluated 4 weeks after the end of the supplementation period. The design of the study is double-blind, randomized, multi-arm, parallel and placebo controlled.
