Filter by:This study is designed to observe the long term clinical outcomes of patient-specific knee arthroplasty in patients with osteoarthritis.
Osteoarthritis of the knee is a degenerative joint disease that involves degradation of the joint. Symptoms include joint tenderness, pain, stiffness, locking, and occasionally an effusion. Over 40 million Americans also have cardiovascular disease in addition to their OA. Initiation and maintenance of even low-levels of physical activity is critical for management of cardiac risk. Patients with osteoarthritis have been shown to have poorer aerobic conditioning, lower daily physical activity levels and lower self-efficacy for exercise than non-OA cohorts. It has been established that there exists a consistent gradient across activity groups indicating greater longevity and reduced risk of CHD, CVD, and stroke, in more active individuals. Available research suggests the greatest gains in cardiovascular fitness occur in moving a sedentary individual to even low levels of physical activity, and 12 weeks is enough to demonstrate change in the risk profile of at-risk individuals. Finally, appropriate levels of aerobic and strength training have been shown to be beneficial in treatment of osteoarthritis of the knee. This study will evaluate the effectiveness of hylan G-F 20 (single injection preparation) in promoting greater levels of physical activity and fitness as measured by MET level compared to an exercise-only cohort; evaluating both the change in physical function as well as the cardiovascular risk profile. This is a randomized, single-blinded clinical trial comparing injection of the knee joint with Hylan GF-20 to sham procedure. Subjects will undergo a regular exercise program for 6 months following randomization.
This study will compare alignment criteria in the Oxford Partial Knee using conventional instrumentation and Signature Custom Guides in order to determine if the use of the Signature Custom Guides results in a higher percentage of knees achieving optimal alignment. The study will also examine outcomes with high volume surgeons (>30 cases/year) and low volume surgeons (<10 cases/year).
The purpose of the study is to determine whether a single intra-articular injection of Durolane 4.5 mL is superior to a single injection of PBS 4.5 mL for the relief of joint pain in patients with osteoarthritis of the knee.
This is a randomized, double-blind, placebo-controlled, multi-center study to evaluate the safety, tolerability, and efficacy of Intra-Articular (IA) verapamil in the treatment of joint pain in patients with knee osteoarthritis (OA). Subjects will discontinue all analgesic medications for the entire duration of the study, except for acetaminophen (taken on an as needed basis at no more than 2 g/day). At visit 2, subjects who meet all entry criteria will be randomized to receive a single injection of IA verapamil or IA placebo at a ratio of 1:1. Treatments will be given with fluoroscopy or ultrasound to confirm needle placement. Subjects will be monitored for blood pressure and heart rate (sitting and standing) for at least 1 hour post-injection. Subjects will be evaluated at weeks 1, 2, 3, 4, 6, 8, and 12 after treatment.
The purpose of this pilot study is to determine the feasibility of conducting a high quality clinical trial to investigate the effects of low intensity, pulsed ultrasound on knee osteoarthritis pain and physical function.
This study is designed to assess: Hypothesis #1: That there is a significant central pain component in a distinct subset of patients diagnosed with knee osteoarthritis(KOA), Chronic low back pain(CLBP), painful diabetic neuropathy(PDN.) Hypothesis # 2: To establish a reliable strategy for differentiation of central pain predominant from peripheral pain predominant knee osteoarthritis(KOA), chronic low back pain(CLBP)and peripheral diabetic neuropathy(PDN) patients using clinical features, experimental pain testing and magnetic resonance(MR) Spectroscopy.
OPEN (Osteoarthritis Physical Activity and Exercise Net) is a website created based on a well developed behavioural theory. This intervention is developed for people with early knee osteoarthritis (OA) who have been sedentary. The investigators aim to engage these individuals to become physically active at a time when their joint symptoms tend to be mild. The primary goal of this proof-of-concept randomized controlled trial is to determine if the OPEN website plus an information pamphlet about OA will improve participation in physical activity in persons with early knee OA, compared to those who receive only the pamphlet.
The purpose of this study is to assess whether a single injection hyaluronic acid (HA) product is not inferior to a 3 injection HA product at 24 weeks (6 months), in terms of effectiveness in reducing pain when walking in patients suffering from symptomatic tibiofemoral osteoarthritis of the knee.
Hypothesis: Viscosupplementation when combined with an off-loading knee brace is more effective in treating the symptoms of knee OA then treating with viscosupplementation alone
