Active clinical trials for "Osteoarthritis"

Patients undergoing total knee arthroplasty will follow two different rehabilitation protocols. In one of them, they will start walking the day of surgery and discharged on a 48 hours basis. On the other one, start walking 3 days after surgery and discharged on a 96 hours basis. Outcomes will be satisfaction, pain, range of movement, incidence of DVT and overall complications.

This is a multi-center, single-arm, open-label study of FX006 in patients with hip OA. A maximum number of approximately 30 patients may be enrolled in this protocol. All enrolled patients will receive a single intra-articular (IA) injection of FX006.

High Tibial Osteotomy (HTO) is an alternative to knee replacement in suitable patients with early knee osteoarthritis (OA), it is particularly suited to patients with single compart disease who otherwise would be suitable for unicompartmental knee replacement (UKR). OA of the knee is very common and increasing driven by the ageing of the population. The current limitations of HTO are related to the difficulty of achieving the desired correction due to a challenging surgical technique and soft tissue irritation due to the use of generic stabilisation plates. This study will examine the safety equivalence of a new patient specific HTO process which has patient specific 3D printed plates, i.e. personalised HTO plates, with the existing most commonly used HTO procedure using the Tomofix generic HTO plate. Importantly this study will be undertaken as a Virtual Trial, existing anonymised 3D imaging data will be used to create the virtual patient cohort. This cohort will receive both procedures, which for this type of procedure is only possible in a virtual scenario. The main question to be addressed is: "Is the personalised HTO procedure as safe as the most commonly used existing generic HTO procedure?". In this context safety concerns the mechanical loads placed upon the tibia and the support plate. The interventions will all be made on computer models, the 3D imaging data will be used to create the intact (un-operated) models of the subject tibias. Each model will then be virtually operated upon, with both the personalised and generic HTO procedures. The models will then be loaded with physiological loads experienced during function and the mechanical states compared.

Prospective observational (non-interventional) cohort study, multi-centric in 5 study Centers in Japan to collect short term clinical and radiological results of the cementless Bicontact® E stem in a standard patient population used in routine clinical practice

Background: Symptoms, balance, mobility, activities of daily life (ADL) and quality of life (QoL) are to be considered in rehabilitation of the individuals with knee osteoarthritis (IKOA). There are several scales to evaluate subjective perceptions and individual components in patients with osteoarthritis (OA). Till date, no scale is available to measure the combined balance, mobility, ADL and QoL in PKOA. Objectives: The objectives of the study are to develop a combined measure of symptoms, balance, mobility, ADL and QoL in PKOA, as comprehensive knee osteoarthritis index (CKOAI) and to validate the scale for its content, reliability and minimum detectable change (MDC) Methods: The study consists of a three stages. First stage is the scale (CKOI) item development and validation. This includes domain and item generating through systematic literature search to extract items related symptoms, balance, mobility, ADL and QoL in IKOA based on the International Classification of Functioning, Disability and Health (ICF) and through structured interviews. During scale validation, an expert panel will review the generated domains and items by Delphi Method, which will undergo revision and pilot testing. Based on the responsiveness of pilot testing will be revised finally. Second stage is to test re-test reliability. The third stage is to report the standard error of measurement (SEM) and minimal detectable change (MDC). Data analysis: All the domains and items in CKOAI will undergo reliability and criterion-related validity. Minimum 50 IKOA will be evaluated with the scale on two occasions within two weeks to establish test retest reliability. Cronbach's alpha for internal consistency and Intra class correlation coefficient for test retest reliability will be used to determine the degree of consistency of items in the scale. MDC will be calculated using the formulae, SEM = SD x √ (1-reliability) and MDC95 = √2 x (1.9) x (SEM). Significant level will be set at p value less than 0.05 (p < 0.05) to minimize the type-I error.

This is a multi-center, prospective, non-controlled post market surveillance study. The objectives of this study are to obtain survival and outcome data on the Allofit IT Shell in combination with the BIOLOX® delta Taper Liner when used in primary total hip arthroplasty.

The arthritis of temporomandibular joint is the most frequent degenerative disease of the jaw joint. Several clinical studies recommend the recourse to the viscosupplement because of its efficiency in the long term. The present research has for objective to find clinical factors predictive of success or failure of viscosupplementation in ATM such as clinical severity before injection, the presence of a limited mouth opening or lenght of symptoms. It is an open observational monocentrical prospective study. The recruitment is competitive and the study will be ended when 44 patients will have been included by taking into account a risk of trial exits or of lost of sight of 10 %.The main criterion is the influence of the radiological stage on the answer to the treatment. Duration of inclusion 6 months. Duration of follow-up 6 months. Total duration of the study 12 months.

Prospective observational study of 6 months of follow-up, of national and multicenter scope with medical device with CE marking and according to the usual clinical practice. In addition, due to the observational design of the clinical investigation, no assignment of the patients will be made to any specific study group, but will be carried out in accordance with the usual clinical practice, not applying any intervention other than the usual one in this type of care practice and always in accordance with current clinical guidelines and recommendations and with the indications authorized in Spain. Patients will be recruited by specialists and will be followed for 6 months under the conditions of usual clinical practice.

Dietary antioxidants might protect from the development of chronic diseases by reducing levels of oxidative stress. The investigators therefore investigated the effect of dietary Non Enzymatic Antioxidant Capacity, which measures interactions between antioxidants in the whole diet, on the risk of 1) myocardial infarction and 2) osteoarthritis.

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.
