Filter by:Cooled radiofrequency ablation (cRFA) of the knee geniculate nerves is a promising treatment option for knee osteoarthritis, but has variable efficacy. Fluoroscopy is the typical guidance of choice, but uses bony landmarks to target these nerves which have variable positions around the knee. Alternatively, ultrasound allows for targeting based on visualization of bony landmarks, the nerves, and their accompanying vascular structures, and thus may offer greater accuracy. However, there are few studies which directly compare the clinical efficacy of these two guidance options. This study will compare these two options.
The objective of this investigation is to evaluate the safety of the geniculate artery embolization (GAE) procedure with HydroPearl® Microspheres in 30 patients with knee pain caused by osteoarthritis with 24 months follow-up. The GAE procedure is an arterial embolization procedure that blocks abnormal blood vessels caused be knee arthritis in order to evaluate the effect on knee pain.
Does the presence of gene polymorphisms -1575G / A in the MMP-2 gene, 836A / G in the MMP-9 gene and -77A / G in the MMP-13 gene, affect the risk of developing idiopathic knee osteoarthritis in the Greek population?
The current common clinical methods cannot truly reflect the biomechanical status of the knee joint. Based on the foot-knee coupling mechanism, the simple and practical dynamic gait touch information provided by the 3D force platform are closely related to the knee biomechanics. The purpose of this study is to investigate the disease feature recognition, computer-aided diagnosis and rehabilitation assessment based on the gait touch information related to lower limb injuries.
The need for exploration of more definitive and cost effective non-arthroplasty treatments of osteoarthritis (OA) has been demonstrated by the orthopedic and health economic research. Embolotherapy of neovessels associated with OA joints has been shown to be promising in patients with knee OA. There is a need for level one evidence drawn from randomized clinical trials to prove the safety, feasibility and efficacy of knee embolotherapy compared to standard of care. This randomized pilot study will assign 10 patients with mild-moderate OA to undergo geniculate artery embolization plus standard of care (defined in this study as: physical therapy and oral anti-inflammatory medications, with a maximum of 1 joint injection at the time of enrollment) and 10 patients to receive only medical standard of care (also having had a maximum of 1 joint injection prior to enrollment). The goal of this pilot study is to obtain preliminary estimates of safety and efficacy of embolotherapy to provide sustained symptom control and modify disease progression in patients with mild to moderate knee OA.
To define the clinical effects of intra-articular transplantation of bone-marrow-derived (BM-MMSCs) and placenta-derived multipotent mesenchymal stem / stromal cells (P-MMSCs) for knee osteoarthritis.
Non-surgical treatment options, like exercise therapy, show excellent short-term effects regarding pain reduction and improvement of knee function. However, mid- and long-term effects are missing so far. This might indicate that long-lasting changes in motor-skill performance (Motor Learning) have not occurred. Motor learning is associated with permanent changes in the capability for skilled movement behavior avoiding unfavorable joint loads and inappropriate muscle activation patterns, leading to compensatory movement strategies. One-sided and high repetitive loads in the knee joint could be one reason for the progression of knee osteoarthritis. Physiotherapeutic strategies should therefore be able to stimulate motor learning processes. In physiotherapy, motor learning can be optimized by using instructions and feedback, targeting an external focus of attention, when learning specific movement patterns. This study investigates the effects of a 12 week exercise therapy program, using an external focus of attention, on functional and biomechanical parameters in patients with knee osteoarthritis. To measure possible changes, functional measurements are taking place at baseline, after 6, 12 and 24 weeks. The biomechanical measurements (3D gait analysis) are taking place at baseline, after 12 and 24 weeks.
This study is a pivotal study to evaluate the efficacy and safety of a single injection of autologous adipose-derived SVF produced using the GID SVF-2 device system for treatment of pain with concomitant improvement in function associated with osteoarthritis of the knee joint.
A promising new approach in total knee arthroplasty (TKA) for severe osteoarthritis of the knee joint is the the kinematic aligned procedure (KA). This technique provides prosthesis-positioning based on natural and individual axes of movement. Although first series have shown satisfying results, further verification by prospective studies and final meta-analyses will be required. Thus, the kinematic alignment represents one of the few new developments in TKA. Provided that patients are willing to participate in the study, patients data are collected preoperatively and during routine follow-up examinations and evaluated prospectively. Patients will receive either a conventionally mechanical aligned arthroplasty or a kinematical aligned TKA, according to a randomized procedure. The kinematic alignment will be achieved by the use of custom-made cutting-blocks. Therefore, the patients will undergo a computed tomography of the whole leg on the affected side. This is mandatory in order to provide the individually produced cutting blocks. In order to ensure comparability, patients are stratified regarding their age and gender before inclusion. Outcome will be measured by the use of standard scoring systems regarding function, pain and ROM (range of motion) three, six and 12 months after surgery. This study is a monocentric, prospective, randomized and controlled open study.
Many surgeons and patients prefer bilateral total knee arthroplasty (TKA) under one anesthesia as single-stage administration. A single-stage bilateral TKA can be performed in two different ways: single-stage, two-team simultaneous bilateral TKA (two surgeons bilateral TKA), and single-stage, a sequential bilateral TKA (single surgeon bilateral TKA). The purpose of this study is to evaluate the radiological results in the single-stage bilateral TKA in terms of two surgeons bilateral TKA and single surgeon bilateral TKA.
