Filter by:Osteoarthritis (OA) is one of the most common joint diseases that is considered a chronic degenerative disorder. There is no effective therapy available today. This prospective clinical trial is designed in an attempt to study the efficacy of mesenchymal stem cells with platelet rich plasma in knee osteoarthritis.
This study will examine the safety and efficacy of autologous adipose-derived stromal vascular fraction (SVF) cells for treatment of hip, knee and thumb osteoarthritis (OA); monitoring adverse events and measuring pain, function and stiffness in the joints of osteoarthritic subjects.
Ankle osteoarthritis is a progressive degenerative joint disease that is characterized by severe pain, loss of autonomy, diminished health-related quality of life, functional disability and diminished physical ability to fulfill occupational duties of life in its end-stage. Current surgical treatments for ankle osteoarthritis are ankle arthrodesis and total ankle replacement. Despite the good pain relief provided by these procedures, patients are still experiencing post-operatively important functional limitations in their activities of the daily living which affect their independency and quality of life. In order to remain capable of performing primary activities of the daily living, those patients have to make functional compensatory adaptations in the ipsilateral adjacent joints that will cause additional degenerative joint disease in those joints. Currently, the outcome of foot and ankle surgery is primarily based on clinical, radiographic and questionnaire outcomes. However, these outcome measures have been criticized for not being sensitive enough to detect clinically meaningful change in foot function. To tackle these shortcomings, an advanced clinical examination platform integrating pressure-force-kinematic measurement devices was developed and showed its clinical value for the detection of intrinsic foot mobility impairments. Surprisingly, up-to-now, no study has included this integrated use of three-dimensional multi-segment foot models, plantar pressure platform and a force platform to report on the functional outcome of an ankle arthrodesis or a total ankle replacement. Therefore, a multi-centre study will be conducted with two foot & ankle surgery centres. Both centres are equipped with the same advanced clinical examination platform. It is believed that proposed approach has the potential to provide further insight in the true functional changes related to ankle arthrodesis and total ankle replacement. This may in turn result in improved rehabilitation, less risk for post-operative complications, earlier discharge and quicker resumption of normal activities of the daily living, which would make ankle arthrodesis and total ankle replacement more cost-efficient and could potentially affect thousands of patients each year. Therefore, the hypotheses of the present study are: - Hypothesis (H1): Subjects with an ankle arthrodesis require a greater reorganization of foot and lower limb kinematic and kinetic patterns to respond to mechanical requirements of level walking compared to subjects with a total ankle replacement. - Null hypothesis (H0): Subjects with an ankle arthrodesis do not require a greater reorganization of foot and lower limb kinematic and kinetic patterns to respond to mechanical requirements of level walking compared to subjects with a total ankle replacement.
Study was designed to evaluate efficacy of autologous platelet rich plasma (PRP) injections guided by ultrasound for treatment of knee osteoarthritis.
Painful osteoarthritis (OA) is the 4th largest cause of disability in the UK. Preoperative temporal summation, a measure of central pain facilitation, has been shown to predict postoperative pain after total knee replacement surgery (TKR). The assessment of the brain's response to noxious stimuli using non-invasive functional MRI (fMRI) may be key in identifying imaging biomarkers within the brain that map central sensitization changes seen in OA. fMRI may help explain why up to 20% of patients undergoing TKR surgery develop persistent post-operative pain. To test these concepts the study aims to functionally characterise the brain activity related to temporal summation of pain in healthy individuals and OA patients using a novel fMRI cuff algometer. Assessment of outcomes in terms of pain and function will be performed 6 months post TKR surgery
The study proposes to compare performances and safety of intra-articular injections of aMAT with those of a control group (PRP injections) for the treatment of symptomatic OA of the knee. The end-points will be determined evaluating the performances of the treatment group in terms of improvement of the symptomatology, functional recovery and radiological appearance.
The usefulness of tranexamic acid(TXA) to reduce blood loss and transfusion in total knee replacement arthroplasty(TKRA) has been demonstrated. However, the optimal does, duration of treatment and route of administration of TXA to reduce blood loss while minimizing adverse effects remain uncertain. Recently, the serial use of perioperative IV and post-operative oral TXA has been shown to significantly reduce transfusion rate without increasing thromboembolic complications compared to placebo. The aim of this study is to 1) determine the beneficial effect and safety of the serial treatment of IV and oral TXA over IV use alone and 2) assess the sufficient length of postoperative use of oral TXA in TKRA patients.
A comparison of intraarticular administration of Hylan GF20, Triamcinolone and both associated in patients with severe osteoarthritis of the knee with follow up of one, three and six months.
Musculoskeletal disorders and degeneration represent injuries or pain in the body's joint ligaments, tendons, muscles, nerves, and skeletal elements that support extremities, spine and related tissues. Direct injuries and aging contribute to breakdown and inflammation of these tissues, leading to debilitation and loss of function in these areas. This has major impact on quality of life, occupational/recreation limitations, and psychosocial implications. Many therapies have been employed including medications, physical therapy, occupational therapy, and a variety of surgical interventions each of which have distinct limitations, often covering the issues versus providing actual healing and return to function. Many reports are now available utilizing self-healing options which include use of stem/stromal cellular therapy or biocellular treatments (either from adipose or marrow) using targeted placement of cells, matrix and platelet concentrates. Termed cellular or Biocellular therapy (typically optimized using ultrasound guidance). It is proposed that use of cellular isolates or cell-stroma derived from the largest deposit of these cells (adipose greater than marrow), may use in conjunction with targeted placement or as a stand alone methodology intravascular use. This study is designed as a interventional means to examine the safety and efficacy of the use of cellular and tissue stromal vascular fraction in musculoskeletal pain, dysfunction degeneration or inflammatory disorders.
The purpose of this observational study is to investigate the prevalence and risk factors of bone degenerative diseases
