Active clinical trials for "Osteoarthritis, Knee"

This study is a phase I clinical trial aimed to determine the recommended dose of 99mTc-NTP 15-5 to obtain the best tracer joints contrast on images without any toxicity.

This is a single-site, three-arm, parallel-group randomized clinical trial (RCT). The clinical effects of a nurse-led, very brief, preoperative mindfulness-based intervention for hip and knee replacement patients will be investigated relative to an audio-recorded very brief, preoperative mindfulness-based intervention delivered during the standard nurse consult and a nurse-led preoperative pain psychoeducation intervention during the standard nurse consult.

Allogeneic mesenchymal trophic factors (MTF) from human umbilical cord tissue-derived mesenchymal stem cells (UC-MSC) injected into the knee joints of 20 patients (group 1) or injected subcutaneously into 20 patients (group 2) is a safe and useful procedure for inducing joint function improvements in osteoarthritis (OA) patients with grade 2, 3, or 4 radiographic OA severity.

Patients with wear and tear in their knees (osteoarthritis) are often referred to orthopaedic surgeons following a sudden worsening of pain and mechanical symptoms (grinding, locking, giving way) in their knee due to tears of their meniscal cartilages. These tears are described as degenerative as they are not usually caused by a single injury but rather accumulation of wear and tear. It is not clear from the current available evidence what the best treatment for these patients is. Their underlying arthritis is not bad enough to require joint replacement yet and they were usually managing well with minimal problems from their knee until experiencing the meniscal tear. However, some of their symptoms are likely to be due to the arthritis rather than just the tear. Current treatment for these patients is usually in the form of conservative treatment with physiotherapy and supervised exercise or using arthroscopy (key-hole surgery) to trim the damaged area of the meniscus. We know from previous research that most of these patients will improve over time to some extent but it is not clear whether a greater improvement can be expected following surgery and if so, whether this applies to all patients with this problem or not. Our study is intended to compare the outcome of patients with proven degenerative meniscal tears imaged on MRI scans, when they are assigned to arthroscopy followed by supervised exercise or supervised exercise alone. They will be randomly assigned and the outcome will be assessed using patient-completed questionnaires (Knee Outcome Osteoarthritis and injury Score [KOOS], SF12, visual analogue score for pain) and whether the patients go on to require further surgery during the period of the trial. The patients will be assessed at baseline, at 6 weeks, 6 months, 12 months and 24 months.

To compare relative efficacy of intraarticular steroid injection using anatomic landmarks vs. fluoroscopy guided technique in decreasing knee osteoarthritis pain 1 month after the procedure.

Osteoarthritic changes in the knee are a common cause of pain that restricts the subject's ability to move and may lead to surgical intervention with total knee replacement. Quadriceps muscle strengthening has been shown to improve the dynamic stability of the knee, decreasing pain during locomotion and increasing knee function. However, the gains associated with improved quadriceps strength have been difficult to achieve on a routine clinical basis because the currently available ways to increase muscle strength- through voluntary exercise or surface electrical stimulation- have significant practical problems that limit their use. The aim of this prospective study is to evaluate the safety and effectiveness of neuromuscular stimulation using implantable microstimulators called BIONs to improve the strength, range of motion, and health of the knee in patients with knee osteoarthritis. This investigation is expected to last 12 weeks for each study participant; the trial will be completed over a 3-year period. Patients recruited into the study will have advanced knee osteoarthritis for which total knee replacement surgery is being considered. The proposed study extends a feasibility study carried out in Milan, Italy on five patients with knee osteoarthritis, who were implanted with BIONs.

The aim of this study is to assess the safety of Stemedica's mesenchymal stem cells in patients with knee osteoarthritis. The route of administration is intraarticular. Safety will be evaluated by AE/SAE incidence and administration tolerance. The subjects will undergo follow-up for 52 weeks. The target population is subjects with knee osteoarthritis (grade II-III in Kellgren-Lawrence scale).

To investigate the clinical benefit of intra-articular injections of saline in patients with symptomatic osteoarthritis of the knee and compare the clinical response of saline to the current standard treatment with corticosteroids and an air injection placebo.

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 is a prospective, multi-center, two-arm, randomized, controlled post-market study to evaluate and compare the clinical accuracy of component placement in robotic-assisted UKA and that of traditional methods.
