Knee Osteoarthritis Knee Oa

Knee osteoarthritis (KOA) is a common joint disease that causes chronic pain and limits daily activities. Current treatments, such as painkillers or surgery, have limitations like side effects or high costs. This study will test whether a safe, non-drug intervention-inspiratory muscle training (breathing exercises against resistance)-can reduce knee pain in people with KOA. The training may work by lowering inflammation and improving the body's nervous system control of pain. We plan to enroll 80 patients aged ≥55 years with confirmed KOA and frequent knee pain. Participants will be randomly assigned to either an 8-week inspiratory muscle training program (5 sessions per week, with gradually increasing resistance) or a sham (very low resistance) training program. Neither the patients nor the researchers assessing the outcomes will know who is in which group. The main outcome is change in knee pain measured by a visual analog scale (VAS). Secondary outcomes include blood markers of inflammation (TNF-α, IL-6, IL1β), physical function, WOMAC score (a KOA-specific questionnaire), activity level, sleep quality, and quality of life. To explore underlying mechanisms, we will also measure heart rate variability (HRV) as an indicator of autonomic nervous system function, and brain functional connectivity in the prefrontal cortex using functional near-infrared spectroscopy (fNIRS). These mechanistic assessments will be performed at baseline and at the end of 8-week intervention. Additional follow-up assessments for clinical outcomes will be done at 3 and 6 months after the training ends. We will also record any side effects or adverse events. This study will provide high-quality evidence on whether inspiratory muscle training is an effective and safe complementary treatment for knee pain in people with knee OA, and will offer new insights into the mechanisms underlying its analgesic effects.

This randomized placebo-controlled trial aims to evaluate the effectiveness of High-Intensity Laser Therapy (HILT) as an adjunct to standard outpatient physiotherapy in patients with knee osteoarthritis. Seventy-two participants will be randomly assigned to receive either conventional physiotherapy combined with active HILT or conventional physiotherapy combined with sham HILT. Outcomes related to pain, knee function, physical performance, muscle strength, range of motion, psychosocial factors, quality of life and body composition will be assessed at baseline, after the intervention, and at 8-week follow-up.

The goal of this study is to create a prospective registry (\<100 patients) to show the effectiveness of the genicular artery embolization procedure overtime in reducing bilateral or unilateral osteoarthritic knee pain as measured by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score.

This study is a randomized, double-blind, multicenter Phase II/III clinical trial designed to evaluate the effectiveness and safety of umbilical cord-derived mesenchymal stem cell (UC-MSC) secretome compared with sodium hyaluronate in patients with knee osteoarthritis. Knee osteoarthritis is a common degenerative joint disease that causes chronic pain and functional limitation. Participants will be randomly assigned to receive intra-articular injections of either UC-MSC-derived secretome or sodium hyaluronate. The study aims to assess improvements in knee pain, physical function, and overall clinical outcomes, as well as to evaluate the safety of the interventions over the study period.

This study aims to examine the effects of moderate-intensity strength training, performed with or without an unloading knee orthosis (valgus-corrective or sham mode), on muscle function, motor unit behavior, and force modulation in patients with moderate knee osteoarthritis

Osteoarthritis (OA) is a non-inflammatory degenerative disease characterized by progressive deterioration of cartilage tissue, synovial membrane, and joint capsule, primarily affecting weight-bearing joints. Individuals with knee osteoarthritis exhibit weakness in the trunk and periarticular muscles. This loss of strength in the trunk and periarticular muscles increases the load on the joint, contributing to the development and progression of the disease. This study aimed to investigate the effects of core stabilization, applied in addition to knee muscle exercise programs, on clinical symptoms and functional capacity in individuals with knee osteoarthritis.

Knee osteoarthritis (KOA) is a leading cause of chronic pain and disability among Veterans, which contributes significantly to reduced mobility, impaired quality of life, and increased health care utilization. First-line therapies, including non-steroidal anti-inflammatory drugs, physical therapy, and intra-articular corticosteroids, provide modest and short-term relief, while being associated with other side effects (i.e., potential for hastened cartilage loss) and no disease-modifying potential. Total knee arthroplasty, although effective, is not suitable for all patients and carries surgical risks. There is an unmet need for effective, durable, and locally-targeted therapies that can alleviate pain and improve function. The development of new therapies for this condition is thus a priority for the VA. While the therapy has been used in humans in other contexts, to date there are no data on the safety, feasibility, and potential efficacy of intra-articular IC14 administration in patients with KOA. A small-scale, Phase I "first-in-joint" pilot and feasibility trial is therefore critical to inform the design and implementation of larger, definitive studies. Specifically, preliminary data are needed to (1) determine the appropriate inclusion/exclusion criteria, (2) solidify the study design and study processes,(3) assess patient tolerance and acceptability of i.a. mAb injection, (4) evaluate safety profiles of the localized biologic intervention. Participants will be randomized into one of three arms, (a placebo arm, a low-dose arm, and a high-dose arm) and will be followed to evaluate the safety and feasibility of this treatment.

The goal of this clinical trial is to see if people with knee osteoarthritis would be willing to comply and adhere to incorporating Recombinant Human Growth Hormone (rHGH), specifically Saizen Somatropin solution, into their treatment plan. Participants will be asked to: * Self-inject the treatment solution (placebo or somatropin) into the abdominal or gluteal area once per day for a total of 6 weeks. * Complete questionnaires related to their knee pain and activities of daily living. * Provide blood tests. * Complete various measurements including: circumference of thigh, calf, and abdomen; strength of thigh and knee; range of motion of both knees; and gait analysis.

Knee replacement surgery is a common and effective treatment for pain and mobility loss, yet up to 1 in 5 patients remain dissatisfied after surgery due to ongoing pain or difficulty with daily activities. Currently, clinicians cannot reliably predict which patients will experience these challenges. This study uses MRI scan of the brain to investigate whether specific patterns of brain activity can predict patient satisfaction after total knee arthroplasty (TKA). By comparing brain networks before surgery and afterward, and linking these changes to patient-reported pain and function, we aim to identify brain-based markers that can help predict outcomes, to improve satisfaction after knee replacement surgery.

This study will assess the efficacy of pulsed electromagnetic field therapy in patients with inflammatory knee osteoarthritis confirmed by MRI-detected effusion-synovitis. Fifty participants will be randomly allocated into two groups. One group will receive active PEMF therapy at a specific optimized parameter twice a week for 8 weeks, while the other group will receive sham treatment using the same device without PEMF signal. The primary outcome is the change in WOMAC pain score, and secondary outcomes include knee function, stiffness, quality of life, and MRI-quantified structural changes.

The twofold goal of this study is to understand the link between muscle power, muscle strength, and muscle control degradation with the risk of falling, and to develop a framework for the comprehensive and quantitative assessment of muscle power (and strength) in an elderly population of patients with knee osteoarthritis, who are at higher risk of falling. The main question it aims to answer is: ● Are muscle power and motor control degradation better predictors of falls than muscle strength in the aging population? Participants will undergo: * Muscle force assessment on a dynamometer * Muscle power assessment on a dynamometer and on isntrumented stairs * Home-based mobility monitoring * Full lower limb MRI acquisition * Gait assessment

This study aims to evaluate the implementation and effectiveness of a self-administered acupressure (SAA) program for knee osteoarthritis (OA) among older adults in Hong Kong community centers. Using a pragmatic cluster randomized controlled trial (RCT) and mixed-methods approach, the research will assess the reach, adoption, implementation, maintenance, and effectiveness of the SAA program in real-world settings, with the goal of informing scalable interventions for knee OA management.

The goal of this clinical trial is to verify whether the "dynamic dual-mode alignment optimization + intelligent precision knee-preserving system" (integrating static/kinematic target alignment, CT-based preoperative three-dimensional \[3D\] planning, 3D-printed guide plates, and intraoperative augmented reality \[AR\] real-time feedback) achieves a greater relative reduction in peak knee adduction moment (KAM) at 12 months postoperatively, while maintaining or improving knee clinical function and without increasing perioperative or long-term complication rates, compared with traditional knee-preserving strategies. The target population is patients aged 40-70 years with knee osteoarthritis (KOA; Kellgren-Lawrence grade II-III) who require high tibial osteotomy (HTO) for unilateral medial-compartment disease with mild-to-moderate varus deformity and who meet the inclusion and exclusion criteria. The main questions are: * Can the dynamic dual-mode alignment + intelligent precision system achieve a greater relative reduction in peak KAM at 12 months postoperatively than traditional knee-preserving strategies? * Can this system improve static alignment accuracy, dynamic load parameters (e.g., KAM impulse and varus thrust), and patient-reported outcome (PRO) scores without increasing complication rates? * Can 3D-printed patient-specific instrumentation (PSI) guide plates and real-time AR feedback reduce intraoperative radiation exposure and shorten operative time compared with traditional methods? Researchers will compare: Kinematic alignment (KA), traditional mechanical alignment (MA), and dynamic dual-mode alignment (DA) to evaluate the relative performance of alignment strategies; 3D-printed PSI-guided HTO versus traditional fluoroscopy-guided HTO to assess the efficacy of PSI; and AR-assisted intraoperative adjustment versus traditional fluoroscopy-based adjustment to evaluate the precision of AR navigation. Participants will: * Complete preoperative assessments, including laboratory tests (complete blood count, biochemistry, coagulation), imaging (full-length, weight-bearing lower-limb radiographs; knee CT and/or MRI as indicated), 3D gait analysis (to measure KAM, KAM impulse, and varus thrust), and PRO assessments (KOOS, WOMAC, and Lysholm scores) * Receive assigned surgical interventions: the DA group will undergo HTO guided by dual-mode alignment plus 3D-printed PSI and intraoperative AR feedback; the MA and KA groups will undergo HTO based on traditional or kinematic alignment, respectively; the traditional HTO group will undergo surgery relying on intraoperative fluoroscopy and surgeon experience. * Attend follow-up visits at 6 weeks, 3 months, 6 months, and 12 months postoperatively, including imaging to assess alignment accuracy and bone healing, gait analysis, PRO assessments, and complication monitoring. * Record medication use and rehabilitation compliance throughout the study period.

Multi-center, prospective, randomized trial of GAE using Nexsphere-F against steroid injection

Study in patients with knee osteoarthritis treated by embolization using NBGM200

This study aims to evaluate the reliability and convergent validity of the Vietnamese version of the Pain Self-Efficacy Questionnaire (VIET-PSEQ) in patients with knee osteoarthritis (KOA). Pain self-efficacy refers to a person's confidence in managing their pain and maintaining daily activities despite it. A total of 173 patients with KOA will be recruited at Gia Dinh People's Hospital using a convenient sampling method. Eligible participants are 50 years or older, diagnosed with KOA, and experiencing chronic knee pain. They will complete the VIET-PSEQ and other health-related questionnaires during an in-person interview. The study will assess internal consistency (using Cronbach's alpha), test-retest reliability (by re-assessing a subgroup after 72 hours), and convergent validity by correlating VIET-PSEQ scores with EQ-5D-5L utility index. Additionally, linear regression analysis will examine how age, sex, pain severity, and education level influence pain self-efficacy. The goal is to determine whether VIET-PSEQ is a reliable and valid tool for measuring pain self-efficacy in Vietnamese patients with KOA.

The primary objective of the study is to determine the effects of Feldenkrais Exercises on Pain, Range of Motion, and Disability in Patients with Knee osteoarthritis. Knee osteoarthritis poses significant challenges in pain management, mobility improvement, and disability reduction among middle-aged to older adults. Feldenkrais Method offers benefits comparable to back school lessons or core stability exercises. This study, conducted as a Randomized Controlled Trial at RIPHAH Rehabilitation Clinic, aims to assess the efficacy of Feldenkrais exercises compared to conventional physical therapy in addressing pain, range of motion, and disability in knee osteoarthritis patients aged 40-60 years. A non-probability convenience sampling method will recruit 32 participants meeting specific criteria for osteoarthritis severity and functional ability. Participants will be randomly assigned to Group A (Feldenkrais exercises) or Group B (conventional therapy), with interventions delivered over four weeks. Group A will engage in Feldenkrais exercises targeting pelvic and lower limb mobility, while Group B will receive standard treatments including knee isometrics, mobilization, transcutaneous electric nerve stimulation, and heating pad applications. Pain severity will be measured using the Numeric Pain Rating Scale, Range of Motion assessed via goniometry, and disability evaluated using the Western Ontario McMaster Universities Osteoarthritis Index. Statistical analysis using SPSS will compare outcomes between groups at baseline, post-treatment, and follow-up assessments.

This study compares the effects of three different intensities of Muscle Isometric Contraction (MIC) on balance ability, proprioception, muscle strength, KOA symptoms, and inflammatory factors in synovial fluid among elderly individuals with Knee Osteoarthritis (KOA).
