Filter by:The purpose of this study is to determine whether habitual physical activity and sedentary behaviour improve six weeks and between three to six months after total knee replacement surgery in people with osteoarthritis.
Osteoarthritis (OA) is a degenerative joint disease in which there is an imbalance between the breakdown and repair of the joint tissue. Intraarticular hyaluronic acid (HA) injections are used for the management of knee OA. Currently, there is limited and inconclusive evidence supporting use of HA injections for management of knee OA. The primary objective of our study is to evaluate the effectiveness of HA injections in the management of knee OA. Investigators will evaluate if HA injections prevent or delay knee OA surgical interventions.
The purpose of this study is to investigate the efficacy and safety of autologous transplantation of Adipose Tissue derived Mesenchymal stem cells (MSCs) in patient with Knee Osteoarthritis.
The focus of this project is to use transcutaneous electrical nerve stimulation (TENS) for the novel indication of treating neuromuscular activation in individuals with knee osteoarthritis (OA) that exhibit neuromuscular activation deficits. The overall goal is to improve outcomes associated traditional therapeutic exercise (TE) by developing an enhanced rehabilitation strategy, which augments TE with TENS (TENS+TE), for the purpose of treating underlying neuromuscular activation deficits. The investigators seek to use TENS to excite neural pathways that immediately increase neuromuscular activation as well as cause sustained improvements in neuromuscular activation and greater strength gains in knee OA patients compared to traditional TE. The investigators will evaluate the effect of TENS+TE on muscle strength, neuromuscular activation, gait biomechanics, physical function, physical activity, self-efficacy of physical activity, self-reported quality of life, disability and pain. The central hypothesis is that an enhanced TENS+TE intervention will lead to better clinical outcomes, increased physical activity, and improved general health. The rationale for conducting a small clinical trial, which demonstrates the feasibility and establishes the preliminary effects of an enhanced rehabilitation strategy, is ultimately to inform the development of a future larger clinical trial to establish the efficacy of an enhanced rehabilitation strategy for knee OA. This hypothesis will be tested through two specific aims: 1) to collect and report data on the feasibility of conducting a clinical trial to evaluate the efficacy of using TENS+TE compared to sham TENS+TE and to TE only for treating patients with knee OA in a clinical setting, and 2) to determine preliminary effects of a 4-week TENS+TE intervention compared to sham TENS+TE, and TE only on muscle strength, neuromuscular activation, gait biomechanics, physical function, physical activity, self-efficacy of physical activity, self reported quality of life, disability, and pain in knee OA patients. Posttests will be at 4 and 8-weeks following baseline.
This pilot RCT study is to examine the comparative effectiveness of two decision aids for hip and knee osteoarthritis.
Our overall hypothesis is that a sudden ambulatory load reduction (caused by corrective osteotomy) leads to changes in cartilage biology that delay or reverse osteoarthritic processes determining the clinical outcome and representing an in vivo model for assessing cartilage mechanosensitivity.
Knee osteoarthritis (KOA) is one of the leading causes of lower limb disability among the elderly and can cause loss of knee joint proprioception that contributes towards deterioration of postural balance. Maintaining a good postural stability is essential while performing everyday functional activities and to avoid falls. Exercise training has been reported to reduce pain as well as improve performance of functional tasks in patients with KOA however compliance to exercise can be challenging due to pain, lack of motivation and traditional nature of exercise that can easily overtax patients. Furthermore, there are not exercise programs that are specifically designed for patients with KOA in order to address lost knee joint proprioception. Recent studies have also demonstrated that visual feedback during exercise can enhance the benefits of exercise training. Therefore, the aim of the proposed study is to implement an interactive sensor-based exercise training to improve postural balance, gait and activities of daily living in patients with KOA.
This study has been designed to conduct as Randomized comparative clinical study.
This study will compare the efficacy of intra-articular betamethasone injection to intra-articular ketorolac injection for symptomatic treatment of knee osteoarthritis in an equivalence study using a double-blinded, randomized, controlled design. Patients will be recruited from orthopaedic clinics at St. Luke's University Health Network. A total of 448 patients will be recruited (224 in each group) to receive an administration of an intra-articular betamethasone or ketorolac injection. The primary outcome is change in pain as assessed by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score. Secondary outcomes include Knee Injury and Osteoarthritis Outcome (KOOS) and Knee Outcome Survey - Activities of Daily Living (KOS-ADL) scores and physical exam findings. Statistical analyses include repeated measures analysis of variance (ANOVA) (primary outcome) and selected ANOVA and nonparametric tests as deemed appropriate (secondary outcomes), with p < .05 denoting significance for all comparisons, and no adjustment for multiple testing.
The purpose of this prospective study is to examine the effect of two local anesthetics used in adductor canal blocks, with relation to pain, analgesic consumption, mobility, and pain related interference with activities and hospital length of stay. The two agents are bupivacaine and ropivacaine. The purpose of this trial is to examine the effect of these drugs being used in adductor canal blocks for pain relief, analgesic consumption, mobility, and pain related interference with activities and hospital length of stay.
