Active clinical trials for "Osteoarthritis, Knee"

The purpose of this study is assess the severity of osteoarthritic knee between one-leg and both-leg standing radiograph in primary OA knee

The purpose of this study is to determine whether different kind of prostesis designs influences in the quality of life of patients

The USAGE study aims at assessing on a long-term period (two years in average) the outcome in clinical or economical term of patients with knee osteoarthritis (OA) treated or not with Synvisc®, in the 1139.4 clinical trial.

The development and implementation of "fast-track" principles in total knee and hip arthroplasty have resulted in early recovery and rehabilitation alongside a reduced length of hospital stay. This without a concomitant increase in morbidity or readmissions for medical or surgical complications and with reduced mortality. However, only little is known about function in the subacute period after arthroplasty, and there is a need for further data on physical and psychological functioning following discharge from hospital.This to ensure, that the positive results from the perioperative setting are carried forward in the subacute phase.

The purpose of this study is to investigate the utility of fentanyl matrix for the treatment of pain due to osteoarthritis (OA) of knee or hip, which was not adequately controlled by non-opioid analgesic (e.g. NSAIDs or COX-II inhibitors) or weak opioids [tramadol HClacetaminophen, tramadol or codeine (or combinations with acetaminophen/ibuprofen)].

The objectives of this study are: to identify and develop techniques to minimize precision errors in magnetic resonance imaging (MRI) evaluation of knee cartilage, and to determine if results from newly-identified MRI techniques in measuring cartilage changes and structure can be reproduced.

Osteoarthritis is the result of the degeneration of the cartilage to articulate, being currently considered as having an multifactorial cause.The knees are one of the affected joints more due to overload that constitutes the main activator or determinative mechanism for the development of the illness. Beyond pain it has important reduction of the amplitude of movement and the muscular force that causes functional limitation and posture's alterations intervening with the activities of daily life. Therefore, the main objective of this study will be to characterize the posture's alterations and the electromiographic activity in patients with osteoarthritis of knees. For this study 30 citizens will be evaluated, 15 with diagnosis of OA of knees unilaterally and 15 healthful citizens, both the groups will be of the feminine sex with age between 60 to 80 years. The selected patients will answer a questionnaire of personal dates and will have an evaluation fiche, in which will be written down: age, index of corporal mass (IMC), index of Lesquene, index WOMAC (Western Ontario and Mac Master), personal and familiar date of the diagnosis, antecedents, instituted treatments, date of the last x-ray, radiological classification of the osteoarthritis according to Scale of Kellgren, electromiographics date and seeming of the postural evaluation. For the electromiographic evaluation the activity of the muscles vastus lateralis and medial oblique in the isometric contraction maximum volunteer (ICMV) and in the march will be analyzed. And for the postural evaluation will be made three photographs in the sights previous frontal and sagittal right and left, being that, for the analysis of the posturais alterations the program will be used SAPO.

Specific Aims: 1) To examine differences between AA and white patients with knee OA in willingness to consider knee joint replacement. 2) To examine the relationship between socio-cultural factors and patient willingness to consider joint replacement. 3) To examine how demographic, socio-cultural, and clinical factors mediate the relationship between race and patient willingness. 4) To examine the relationship between patient willingness and referral to orthopedic care for knee OA (secondary aim). Experimental design/Methodology: A cross-sectional survey study design will be used to examine socio-cultural and clinical factors that may vary by race/ethnicity and may be determinants of willingness to consider joint replacement as a treatment option. Patients with symptomatic and radiographic knee OA from the primary care clinics will be surveyed. Only individuals with knee OA of sufficient severity that would be considered candidates for joint replacement will be included. Analytic strategies include ordinal logistic regression, path analysis, and regression trees. Subject population: The study sample will consist of approximately 133 African American and 419 white patients with OA of the knee in a primary care setting.

The purpose of this study is to use better magnetic resonance imaging (MRI) techniques to examine the knee and the bony and soft tissue changes so as to better predict the progression of osteoarthritis and acute knee injuries.

PhotoBioModulation (PBM) is a mature science with therapeutic efficacy in humans and animals, and with excellent results in different medical specialties without side effects. However there are gaps that prevent adoption on a large scale. Recent research developed by our group and partners allowed us to understand the mechanisms of action of PBM, from Molecular Physics through Biochemistry and with consequent clinical validation, with precise, replicable and personalized therapeutic results. These findings have led to treatments for many kinds of pains with industrial predictability and accuracy, phenotypic adequacy technologies that are encapsulated, prescribed, and applied. Photobiomodulation applications cover treatments for pain, inflammation, tissue regeneration, healing, immune system activation, all of which are essential characteristics for osteoarthritis therapy. Our idea is to formulate great challenges of Photobiomodulation as a solution to osteoarthritis as follows: 1) Make PBM-based therapies as predictable as drug-based therapies; this is possible with precise dose calculation performed by our team; 2) Map the biochemical and molecular effects of PBM, including those related to gene expression; 3) Unify PBM theory by synthesizing and giving meaning to the millions of PBM data associated with osteoarthritis and correlating with clinical study to be performed under this thematic project. Overcoming these challenges, PBM will become a complementary (or supplementary) alternative to medications, physiotherapy and surgical procedures for the treatment of osteoarthritis.
