Active clinical trials for "Osteoarthritis, Knee"

The main aim and scope is making measurement and comparison about the femoral component posterior offset under different femoral component implanting flexion angle in cruciate retaining total knee arthroplasty. The results may identify the influence of the flexion component implanting flexion angle on the femoral component posterior offset.

Rehabilitative Sanomechanics Method (RSM) of exercise designed to restore normal subperiosteal transmission of in-joint pressures and normalizing contact pressures on cartilages, will reduce pain in the affected joints and improve locomotor function.

This is a randomized control trial where patients will be randomized to receive one of two types of total knee arthroplasty (TKA) all-polyethylene (AP) tibial components: cruciate retaining (CR) or posterior stabilized (PS). We will use radiostereometric analysis to assess the stability of the implants at 6 weeks, 3 months, 6 months, 1 year and 2 year post-operatively. The main objective of this project will be to determine which AP tibial component offers the greatest stability. Additionally, we will seek to determine whether patient BMI significantly impacts the stability of AP tibial components.

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.

The purpose of this study is to compare results obtained with gender-specific and traditional knee replacement systems design among women undergoing total knee replacement surgery. Women who qualify and agree to participate will be randomly assigned to receive either a traditional or gender-specific knee replacement. During surgery, measurements of bone resection and bone-to-implant relationships will be recorded. At selected time intervals, participants will be asked to fill out questionnaires regarding pain and function, will be examined by their surgeon and routinely obtained xrays will be evaluated. In addition, a subset of participants will be randomly selected to undergo gait analysis to evaluate knee motion and muscle function.

This is a randomized study investigating whether identification, ligation, and burial of superficial branches of the saphenous nerve crossing the surgical field during total knee arthroplasty reduces the rate of post-operative anterior knee pain and neuralgia compared to standard total knee arthroplasty.

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 study allows patients to take part of the decision making between a unicompartment knee (partial ) or a total Knee replacement . Using the measures of a decision aid questionnaire which explicitly details the risks and benefits of both procedures.The study will use subjective (reported by patient) and objective data (which will be measured) to allow the determination if one option is superior to the other. Information gathered from this study will be used to assist future patients in selecting the surgical option that best fits their life style. A feasibility pilot study of a randomized clinical trial will help to evaluate the outcomes of both procedures and help shape a multicentre Canadian study.

Participants will be randomized to undergo a High Tibial Osteotomy (HTO) with or without a knee scope. Patients will be tested in the Gait Lab, will fill out quality-of-life questionnaires, and have a clinical evaluation done preoperative and at each follow-up visit.

The aim of this study to evaluate whether the position of the sagittal patellar offset is a predictive factor for anterior knee pain in subjects having undergone bilateral multiradius total knee replacement.
