Filter by:A total knee replacement is the removal of parts of the knee joint, that have become damaged due to osteoarthritis, and replacing these with artificial implants. The placement of these artificial implants and how they are aligned with each other is important because they can impact overall knee function and the long-term survival of the implant. It is reported that up to 34% of all patients following total knee replacement (TKR) have poor outcomes functionally. There have been significant developments in knee replacement surgery over recent years. In particular, the introduction of robotic surgical systems, such as the NAVIO and CORI systems (Smith+Nephew Plc). The NAVIO and CORI Surgical Systems are hand-held devices which can support the surgeon with the knee replacement procedure, the systems are image-free and do not require the patient to undergo any scans (such as CT scans). During the surgery, the surgeon uses the NAVIO/CORI hand-held device to map specific landmarks within the knee joint and determines the desired alignment using associated computer software. The tools to remove the bone and place the implants are controlled by the surgeon with the guidance of the NAVIO/CORI software. Comparisons of robotic systems to conventional instruments have demonstrated that robotic platforms produce fewer positioning errors in total knee replacement. This can result in more precise knee alignment and better outcomes following surgery. With both the NAVIO and CORI Surgical Systems there is a reduction in radiation exposure due to them being image-free. At present, there is some evidence available for the long-term outcomes of total knee replacement implanted using robotic assistance (i.e. 2-10 years) however this study is designed to look at the early outcomes following TKR. There is no literature to date to show that robotic-assisted TKR is superior to conventional methods, within the early post-operative period (up to 12 months). This study is designed to show that the NAVIO/CORI surgical systems are better than conventional methods for TKR. The hypothesis is that they will be cost-effective, will reduce the time a patient spends in hospital following their surgery, will improve patient satisfaction during the early recovery period and will improve the patient's early post-operative mobility and function.
Preliminary safety and efficacy of XT-150 in the synovial capsule of osteoarthritic facet joints in the vertebra of the spine.
A randomized, double-blind, placebo-controlled trial comparing a single intra-articular injection of 2.0 mL AlloGen vs 2.0 mL sterile saline. Patients will be evaluated at baseline, 1 week, 6 weeks, 12 weeks, and 26 weeks.
Symptomatic knee osteoarthritis (OA) is the most common joint disorder in the U.S. and a leading cause of disability. Increasing age, obesity, and previous injury increase the lifetime risk of knee OA, but these factors are also independently associated with increased cellular senescence. Senescent cells accumulate in many tissues and contribute to chronic pathologies, linked to the secretion of pro-inflammatory factors collectively known as the senescence-associated secretory phenotype. In OA, senescent cells promote production of cytokines, chemokines, and matrix-degrading enzymes involved in progressive cartilage breakdown. The senolytic supplement fisetin alters the inflammatory and catabolic cartilage responses, which may clinically lessen OA pain while also slowing progressive cartilage breakdown. The purpose of this double-blind, randomized clinical trial is to compare 2 fisetin dosing regimens versus placebo. Sixty patients with mild to moderate knee OA will be assessed at baseline and 3 months in an effort to: determine if 2 different fisetin dosing regimens lessen pain and functional impairment compared to placebo, compare progressive changes in senescent cell activity and biomarkers of cartilage degradation between different fisetin dosing regimens and placebo, and assess acceptability and feasibility of 2 fisetin dosing regimens.
This is a three-arm prospective double-blinded randomized comparative trial aimed at comparing results regarding knee pain improvement in patients with osteoarthritis (OA) of the knee awaiting total knee arthroplasty (TKA) by either a sham procedure, a geniculate artery embolization procedure or a geniculate nerve ablation procedure. Experienced interventional radiologists and anesthetists at the McGill University Health Centre (MUHC) and study affiliated centers will carry out all interventions. 72 consecutive subjects meeting the eligibility criteria, considered for knee replacement in the future. Patients will be randomized to receive either the embolization procedure, the nerve ablation procedure or a sham procedure. Monitoring of pain will be recorded using visual analog scales, pain medication use, and Western Ontario and McMaster Universities Arthritis Index (WOMAC) and osteoarthritis knee and hip quality of life questionnaire (OAKHQOL) questionnaires over a period of 1 year post-treatment or up to the time of surgery. Pain and recovery post surgery will be monitored as well in patients who do get the Total Knee Arthroplasty (TKA) before the 1 year mark.
Knee osteoarthritis (OA) is an incurable disease that involves breakdown of the knee joint. This breakdown is often accompanied by knee pain and stiffness, which can limit a person's daily physical activity. Fortunately, there are treatments that may stop or slow the progression of knee OA. Bone marrow aspirate can be extracted and processed into autologous, nucleated cells, then injected back into the knee affected by OA. These cells provide important nutrients that can improve the health of the knee joint and alleviate the symptoms of knee OA. Therefore, the investigators are interested in determining whether an injection of autologous, nucleated cells can improve physical activity, pain and function in people who are diagnosed with knee OA. The investigators will recruit a total of 100 subjects for this study and examine changes in physical activity using a research-grade Actigraph Monitor.
Calypso Knee System Clinical Study, OUS for subjects with symptomatic osteoarthritis of the medial compartment of the knee. The sub-study will achieve continued evaluation of the safety and clinical effectiveness of the Calypso Knee System.
This randomized, double-blind 2-arm parallel group study to determine the efficacy of a cannabinoid (CBD) patch on reducing pain in patients with knee osteoarthritis.
Efficacy and safety study of resiniferatoxin versus placebo to manage pain in patients with knee osteoarthritis whose TKR surgery is delayed
The purpose of this study is to determine if there is a difference in clinical outcomes after total knee replacement (TKR) performed with traditional ligament balancing compared to use of intraoperative sensing technology (IOS) to balance ligaments. IOS is used to send real time information to a monitor within the operating room that assists your surgeon in making decisions about the balance of the ligaments in your knee and the proper insertion of implants. A total of 150 subjects will participate in this study at Hospital for Special Surgery. The hypotheses are that the use of IOS technology will be associated with: 1. Better soft tissue balance during TKR than by manual balancing alone. 2. Higher patient reported clinical outcome measures (PROMs) following surgery.
