Filter by:Patients referred to Calgary's Alberta Hip & Knee Clinic, while awaiting consultation with an orthopedic surgeon for hip or knee osteoarthritis, will be offered the opportunity to participate in a dietary counseling program with the goal of attaining weight loss prior to surgery. Those patients interested in participating in the program will be offered the opportunity to participate in the research trial.
Due to enforced social distancing as a direct consequence of the COVID-19 pandemic, many on-site health care services are unavailable. This study seeks to investigate the relative effectiveness of an alternative on-line delivery model of exercise and education compared to on-site delivery in patients with knee osteoarthritis.
A promising new approach in total knee arthroplasty (TKA) for severe osteoarthritis of the knee joint is the the kinematic aligned procedure (KA). This technique provides prosthesis-positioning based on natural and individual axes of movement. Although first series have shown satisfying results, further verification by prospective studies and final meta-analyses will be required. Thus, the kinematic alignment represents one of the few new developments in TKA. Provided that patients are willing to participate in the study, patients data are collected preoperatively and during routine follow-up examinations and evaluated prospectively. Patients will receive either a conventionally mechanical aligned arthroplasty or a kinematical aligned TKA, according to a randomized procedure. The kinematic alignment will be achieved by the use of custom-made cutting-blocks. Therefore, the patients will undergo a computed tomography of the whole leg on the affected side. This is mandatory in order to provide the individually produced cutting blocks. In order to ensure comparability, patients are stratified regarding their age and gender before inclusion. Outcome will be measured by the use of standard scoring systems regarding function, pain and ROM (range of motion) three, six and 12 months after surgery. This study is a monocentric, prospective, randomized and controlled open study.
The goal of this study is to validate the pharmacodynamic model for pain relief from oxytocin at a peripheral site by intravenous infusion targeted at different levels of the drug. In this study healthy volunteers and people with knee arthritis so severe that they may need joint replacement are recruited for a one day study. Each study participant will have an intravenous(IV) catheter placed. After placement of the IV catheter oxytocin will be given by IV infusion in varying amounts. The study team will perform some tests to evaluate how oxytocin changes perceptions on the skin. The study team will study a painful perception by placing a probe on the skin and heating it to 113 degrees Fahrenheit for 5 minutes. Each study participant will score any pain that is experienced on a 0 to 10 scale.
Many surgeons and patients prefer bilateral total knee arthroplasty (TKA) under one anesthesia as single-stage administration. A single-stage bilateral TKA can be performed in two different ways: single-stage, two-team simultaneous bilateral TKA (two surgeons bilateral TKA), and single-stage, a sequential bilateral TKA (single surgeon bilateral TKA). The purpose of this study is to evaluate the radiological results in the single-stage bilateral TKA in terms of two surgeons bilateral TKA and single surgeon bilateral TKA.
In Hong Kong, joint diseases are common health problems as identified by the Elderly Health Service under the Department of Health. It accounts for most of the disability of the elderly in Hong Kong. In particular, osteoarthritis (OA) is on the rise and the prevalence of OA increases with age. Women are more likely to have OA in knee and hip joints after menopause. A study in 2000 reported that among Hong Kong people aged 50 and above, 7 percent of men and 13 percent of women suffered from OA. With an ageing population, it is expected that OA will become a major public health problem in Hong Kong and worldwide and the socio-economic cost of supportive care to these patients can become a major burden to Hong Kong society and many regions in the world. Early diagnosis and prevention of OA and effective technology for treatment monitoring are very important. At present, the management of OA is not optimal and standard quality indicators suggest that the majority of persons with the disease do not receive appropriate care. Over half of the population affected with OA are unaware of the diagnosis. The research team have developed a quantitative and fully automated non-contrast MRI application for early detection and monitoring of joint diseases. The whole project was funded by the Innovation and Technology Fund (ITF) (MRP/001/18X ) started in January 2019. This clinical trial is part of the quantitative assessment of this developed technology. The team anticipate this innovation will address both OA diagnosis, surveillance and management. This can potentially increase diagnostic capabilities with minimum efforts, improving patient awareness, and improved treatment monitoring of the disease state after the interventions. Thus, the proposed technology is expected to provide betterment in the quality of life for the elderly population.
This is a study of participants that will receive an intravenous (IV) infusion of oxytocin (naturally occurring hormone that is made in the brain). In this study healthy volunteers and people with knee arthritis so severe that they may need joint replacement are recruited for a one day study. Each study participant will have an IV catheter placed. After placement of the IV catheter oxytocin will be given by IV infusion. Investigators will perform some tests to evaluate how oxytocin changes perceptions on the skin. Investigators will study a painful perception by placing a probe on the skin and heating it to 113 -117 degrees Fahrenheit (F) for 5 minutes. Each study participant will score any pain that is experienced on a 0 to 10 scale, and most people find that pain rises during the 5 minutes, but remains mild, usually around only 1 or 2 on the 0 to 10 scale. The 5 minute heating temperature will be determined according to the subjects pain rating during the screening visit. The main goal of the study is to determine the effect of oxytocin during and after a fixed rate intravenous infusion on reduction in pain to a sustained heat stimulus in order to generate a model for peripheral analgesia.
The main purpose of this study is to define the maximum effect oxytocin (naturally occurring hormone that is made in the brain) has on pain from a 5 minute heat probe applied to the skin and to get an estimate for the relationship between the amount of pain relief at different amounts of oxytocin in the blood. This is a study of participants that will receive an intravenous (IV) infusion of oxytocin (naturally occurring hormone that is made in the brain) with blood samples taken thereafter in order to create a formula to describe the concentrations of oxytocin in the blood over time (pharmacokinetics). In this study healthy volunteers and people with knee arthritis so severe that there is a need for a joint replacement are recruited for a one day study. Each study participant will have 2 IV catheters placed (one in each arm). After placement of the IV catheters, 4 different levels of oxytocin will be given by IV infusion. Blood samples will be taken before the infusion begins and after each different level of the infusion. The blood will be drawn through the second IV catheter. The study team will also do some tests to get a rough idea of how oxytocin changes perceptions on the skin and how this relates to the amount of oxytocin in the blood at the same time. The study team will study a painful perception by placing a probe on the skin and heating it to 113 degrees Fahrenheit for 5 minutes. Each study participant will score any pain that is experienced on a 0 to 10 scale.
The main purpose of this study is to sample the blood and calculate the pharmacokinetics (PK) of oxytocin. This is an unblinded, sequential study of subjects, all of whom will receive an intravenous (IV) infusion of oxytocin (naturally occurring hormone that is made in the brain) with blood samples taken thereafter in order to create a formula to describe the concentrations of oxytocin in the blood over time (pharmacokinetics). In this study healthy volunteers and people with knee arthritis so severe that they may need joint replacement are recruited for a one day study. Each study participant will have 2 IV catheters placed (one in each arm). After placement of the IV catheters and infusion of oxytocin will be given over a 10 minute period. Blood samples will be taken before the infusion begins and several times during and after the infusion. The blood will be drawn through the second IV catheter. The investigators will also do some tests to get a rough idea of how oxytocin changes perceptions on the skin and how this relates to the amount of oxytocin in the blood at the same time. Two kinds of perceptions will be studied. First, the investigators will study a painful perception by placing a probe on the skin and heating it to 113 degrees Fahrenheit for 5 minutes. Each study participant will score any pain that is experienced on a 0 to 10 scale, and most people find that pain rises during the 5 minutes, but remains mild, usually around only 1 or 2 on the 0 to 10 scale. Secondly, the investigators will study the perception of vibration, like one feels with a tuning fork on the skin. For this the investigators will put a controlled vibration device on the arm and start the vibration at such a high frequency (1000 times per second) that it cannot be felt as vibrating. The investigators will slow the frequency until the study participant first feels vibration, then turn off the machine and record this threshold frequency where it is first felt.
The purpose of this follow-up study is to investigate the efficacy and safety of autologous Adipose Tissue derived Mesenchymal stem cells (JOINTSTEM®) in patient with severe Knee Osteoarthritis.
