NCT00102544
This study will evaluate the accuracy and effectiveness of an experimental tracking device for locating abnormalities during invasive procedures, such as biopsy or ablation, that cannot easily be visualized by usual imaging techniques, such as computed tomography (CT) scans or ultrasound. Some lesions, such as certain liver or kidney tumors, small endocrine abnormalities, and others, may be hard to find or only visible for a few seconds. The new method uses a needle with a miniature tracking device buried inside the metal that tells where the tip of the needle is located, somewhat like a mini GPS, or global positioning system. It uses a very weak magnet to localize the device like a miniature satellite system. This study will explore whether this system can be used in the future to more accurately place the needle in or near the desired location or abnormality. Patients 18 years of age and older who have a lesion that needs to be biopsied or an ablation procedure that requires CT guidance may be eligible for this study. Candidates are screened with a medical history and review of medical records, including imaging studies. Participants undergo the biopsy or ablation procedure as they normally would, with the following exceptions: some stickers are placed on the skin before the procedure and a very weak magnet is placed nearby. The needles used are similar to the ones that would normally be used except that they contain a metal coil or spring buried deep within the needle metal. The procedure involves the following steps: 1. Small 1-cm plastic donuts are place on the skin with tape. 2. A planning CT scan is done. 3. The CT scan is sent to the computer and matched to the patient's body location with the help of a very weak magnet. 4. The needle used for the procedure is placed towards the target tissue or abnormality and the "smart needle" location lights up on the old CT scan. 5. A repeat CT is done as it normally is to look for the location of the needle. 6. After the procedure the CT scans are examined to determine how well the new tool located the needle in the old scan.

Background: \- To understand diseases of the retina and the eye, information is needed about people with and without such diseases. Researchers want to study these people and follow them over time. They also want to study body tissues and blood to understand the nature of eye disease. Studying genes, cells, and tissues may help them understand why some people get eye problems and others do not, or why some people respond to treatment while others do not. Researchers want to collect physical samples and personal data to develop a National Eye Institute database. Objectives: \- To collect health information and blood and tissue samples from people with and without eye diseases, to be used in research studies. Eligibility: * Individuals at least 2 years of age with different types of eye disease. * Healthy volunteers with no history of eye disease. Design: * Participants may be recruited from National Eye Institute studies or may be referred from other sources. * Participants will be screened with a physical exam and medical history. They will also have a full eye exam. Questions will be asked about family medical history, especially about eye disease. * Blood samples will be collected. Other samples, such as saliva, tears, hair, stool, and urine, may be collected as needed. Adult participants may also provide a skin sample. * Tissue or fluid from eye collected as part of eye care or treatment may also be added to the database. * No treatment will be provided as part of this study.

NCT06903936
Knee arthritis is a chronic joint disease that causes pain, disability and impaired quality of life, leading to significant social and health problems worldwide. Moreover, these public and economic impacts related to osteoarthritis of the knee are expected to increase in the future. With the global increase in the proportion of the elderly population, overall obesity rates and the associated incidence of osteoarthritis of the knee, clinicians are now focusing on new treatment strategies. The diagnosis is usually made by history, physical examination and radiography (X-ray) and there is no need for additional examination. Today, both non-surgical and surgical interventions are used in the treatment of knee arthritis. Non-surgical options include patient education, weight loss, physical therapy (PT), support or foot orthosis, oral painkillers, non-cortisol anti-inflammatory drugs, cortisols, hyaluronic acid, plasma injections rich in platelets, prolotherapy, stem cell therapy and genicular nerve blocks. The aim of the study was to compare the benefits of genicular nerve block and physical therapy in volunteers with knee pain for more than 3 months like you and to determine the most appropriate method. In this study, Genicular nerve block and Physical therapy in patients with knee arthritis; * Effects on knee pain, mobility and functional ability * It is aimed to examine the effects on equilibrium parameters. A total of 66 participants will be included in the study. Participants will be randomly assigned to three groups by envelope selection method. Your treatment method will be determined according to the treatment method in the envelope you choose.
NCT07020312
After orthopedic surgeries like knee or hip replacement, some patients struggle to fully activate their muscles due to a condition called Arthrogenic Muscle Inhibition (AMI). AMI can slow recovery and make physical therapy less effective. This clinical trial is testing whether a special type of brain training-called neurofeedback visualization training-can help improve muscle activation and speed up recovery. In this study, patients will receive standard physical therapy after surgery. Half of them will also use a device that helps them "visualize" exercises while wearing a cap that reads brain signals (EEG). The cap tracks brain activity when patients imagine doing specific movements. A computer then shows a virtual avatar performing the movements, giving feedback in real time-like a video game controlled by the brain. The study includes patients recovering from one of four surgeries: 1. Anterior cruciate ligament reconstruction (ACLR) 2. Total knee arthroplasty (TKA) 3. Total hip arthroplasty (THA) 4. Hip arthroscopy (HA) for femoroacetabular impingement (FAI) The goal is to see if this training improves muscle strength, movement, and daily function more than standard therapy alone. The study will take place at Rush University Medical Center in Chicago and enroll 240 adults, with 60 patients per type of surgery. Each participant will be followed for up to 6 months after surgery and complete strength tests, movement assessments, and questionnaires about their recovery. The hope is that combining brain training with physical therapy will lead to faster, more complete recoveries and improve how patients move after surgery.
NCT07655388
Surgical wound complications following primary total hip arthroplasty remain a significant clinical challenge despite advances in wound care technologies. The optimal choice of dressing and frequency of dressing changes remain insufficiently investigated, particularly regarding their influence on wound healing and the wound microenvironment. This prospective, randomized, controlled clinical trial aims to evaluate the impact of dressing type and dressing change frequency on surgical wound healing in patients undergoing primary total hip arthroplasty. Ninety patients will be allocated into three treatment groups receiving either a capillary-action dressing system (VACUTEX™) or standard dressings with different dressing change intervals. The study will assess time to complete wound epithelialization, postoperative wound complications, pain intensity, wound temperature, exudate pH, length of hospital stay, and time to suture removal. In addition, the study will investigate the potential role of wound temperature and exudate pH as early indicators of impaired healing and postoperative complications.
NCT06893250
The goal of this randomized clinical trial is to compare treatment for osteoarthritis in the knee using platelet rich plasma (PRP) or adipose stem cells (ADS). The main questions it aims to answer are: * Will the patients clinically benefit from the treatment, and if so, which treatment is better? * Will there be radiological findings to support this? Participants will be randomized into one of four groups: PRP, ADS, PRP + ADS or placebo treatment (saline) and will be examined and get an X-ray and MRI of the knee taken at inclusion and after 1 and 2 years.
NCT02838069
ASCs will be administered via intra-articular use into the knee joint affected by OA where they are expected to exert their therapeutic effects. The objective of this clinical trial is to generate efficacy and tolerability profiles of single injections of 2 dosages of autologous ASCs versus standard of care (placebo), when administered locally into a knee joint affected by OA after in vitro cell expansion. The potential of ASC to lead to a disease-modifying therapeutic option for the treatment of this chronic and debilitating disease will be assessed by MRI after 1 and 2 years. This will be a phase IIb, multi-centre, prospective, randomized, double-blind study, comparing culture-expanded autologous ASC with placebo.
NCT07642258
Osteoarthritis (OA) of the knee, also referred to as degenerative joint disease, is normally due to wear and tear and progressive cartilage loss in the articular cartilage. Osteoarthritis is most prevalent condition among older adults. The objective of the study will be to compare the effects of Sahrmann's approach versus conventional treatment on pain, valgus angle and functional disability in patients with knee osteoarthritis.
NCT07643662
Knee osteoarthritis is a common condition that causes knee pain, stiffness, reduced mobility, and difficulty performing daily activities. Many patients seek non-surgical treatment options to help manage their symptoms and improve their quality of life. This study aims to evaluate the effectiveness and safety of Mobithron® Xtra, an oral health supplement containing hyaluronic acid, undenatured type II collagen, and Boswellia serrata extract, in adults with primary knee osteoarthritis. Participants will take Mobithron® Xtra once daily for 3 months as part of their routine care. The study will observe changes in knee pain, stiffness, physical function, treatment satisfaction, and overall perception of improvement using validated patient-reported outcome measures, including the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Visual Analogue Scale (VAS), Treatment Satisfaction Questionnaire for Medication (TSQM), and Patient Global Impression of Change (PGIC). This is a prospective, multicentre observational study involving patients receiving treatment in participating general practitioner clinics throughout Malaysia. No experimental procedures will be performed, and participants will continue to receive standard clinical care. Safety will be monitored throughout the study by documenting any adverse events reported by participants. The findings from this study may provide valuable real-world evidence regarding the role of Mobithron® Xtra in improving symptoms and quality of life among patients with primary knee osteoarthritis.

Background: Retinal hemangioblastoma (RH) is a tumor. It grows from the retina in the eye. It can threaten a person s vision. Trans-scleral cryotherapy is used to destroy the tumors and minimize the long-term risks of vision loss. RH is a rare condition, often occurring in people with von Hippel-Lindau disease. There are no clinical trials to study how well the treatment works. Researchers want to study the medical records of people with RH who were treated at the NIH eye clinic to learn more. Objective: To analyze clinical data collected over a 20-year span to study consecutive cases of RH managed with trans-scleral cryotherapy at the NIH. Eligibility: People who took part in NIH natural history protocols for which cryotherapy of RH was performed as a standard care measure. Design: Researchers will collect and study data from participants medical charts. Participants will not be contacted because no new data is needed. Researchers were granted a waiver of informed consent for use of these medical records. To protect patient privacy, participants will be assigned an ID number. Their data will be entered into a spreadsheet in a coded fashion. The key to this code will be kept in a secure file. No patient identifying information will be used in the analysis or the publication....
NCT07634302
Obesity is a major modifiable risk factor for knee osteoarthritis and is associated with chronic low-grade inflammation, pain, functional impairment, and cartilage degradation. Weight reduction is recommended as a core component of osteoarthritis management, while resveratrol has demonstrated anti-inflammatory and chondroprotective properties in experimental and clinical studies. However, the potential additional benefit of resveratrol supplementation when combined with dietary intervention remains uncertain. This randomized controlled trial evaluated the effects of 150 mg/day trans-resveratrol supplementation as an adjunct to a low-calorie diet in postmenopausal women with obesity and knee osteoarthritis. Ninety-seven participants were randomized to receive either a low-calorie diet alone or the same diet combined with resveratrol for 10 days. Outcomes included pain intensity, functional status, urinary C-terminal telopeptide of type II collagen (CTX-II), anthropometric parameters, body composition, metabolic markers, lipid profile, and inflammatory biomarkers.

This post market clinical follow-up study is designed to confirm safety and performance of the Sidus Stem-Free Shoulder when used in hemi or total shoulder arthroplasty. The safety of the implant will be evaluated by monitoring the frequency and incidence of all kinds of adverse events. The performance will be determined by analyzing the implant survival, overall pain and functional performances (based on Constant \& Murley score and ASES score), subject quality of life (EuroQol EQ5D) and radiographic parameters (e.g. radiolucencies, osteolysis, component migration) of study subjects who received the Sidus Stem-Free Shoulder. The Sidus Stem-Free Shoulder is not approved for use in the US.
NCT07625150
This project aims to develop an \[18F\] fluorodeoxyglucose (FDG) positron emission tomography (PET) / magnetic resonance imaging (MRI) method to locate the painful inflammation in PFJ OA associated with joint loading. \[18F\] FDG PET/MRI is an emerging pain imaging approach with enhanced sensitivity to painful hypermetabolic inflammation through evaluation of intracellular glucose utilization rate via (\[18F\]FDG PET) and fine anatomy details (MRI). The investigative group has shown its promise in revealing previously unidentified or unspecified pain generators in various musculoskeletal pain conditions. The investigators have also demonstrated the feasibility of visualizing the structural changes between unloaded and loaded knee joints with MRI, which can be easily adopted in the current PET/MRI setting. The main challenge in the proposed \[18F\]FDG PET/MRI approach is to differentiate the normal uptake of FDG for metabolic changes by weight-bearing from abnormal changes indicating eventual pain aggravation by weight-bearing and knee-flexion. The investigators have garnered the following two aims to validate the proposed method by comparing unloaded and loaded knee imaging results between PFJ OA pain patients and asymptomatic, matched controls.

NCT04456569
The need for exploration of more definitive and cost effective non-arthroplasty treatments of osteoarthritis (OA) has been demonstrated by the orthopedic and health economic research. Embolotherapy of neovessels associated with OA joints has been shown to be promising in patients with knee OA. There is a need for level one evidence drawn from randomized clinical trials to prove the safety, feasibility and efficacy of knee embolotherapy compared to standard of care. This randomized pilot study will assign 10 patients with mild-moderate OA to undergo geniculate artery embolization plus standard of care (defined in this study as: physical therapy and oral anti-inflammatory medications, with a maximum of 1 joint injection at the time of enrollment) and 10 patients to receive only medical standard of care (also having had a maximum of 1 joint injection prior to enrollment). The goal of this pilot study is to obtain preliminary estimates of safety and efficacy of embolotherapy to provide sustained symptom control and modify disease progression in patients with mild to moderate knee OA.
