Filter by:This is a prospective, observational study, aimed to establish the relationship between an inefficient endogenous pain modulation before surgery (total knee arthroplasty; TKA) and the probability to develop chronic pain after surgery (persistent post surgical pain). Endogenous analgesia efficiency will be measured during the month previous to surgery using quantitative sensory testing (QST). Persistent post surgical pain will be defined as presence of pain in movement greater than 3 points in a 0-10 numerical scale in the operated knee, 6 months after surgery.
Post-operative pain following total knee replacement can be disabling and sometimes lead to the need for prolonged hospital stay. Therefore development of improved post-operative modalities for total knee replacement surgery pain control is important. High-resolution ultrasound (US) allows accurate visualization of nerves and surrounding structures and can lead to higher success rates of nerve block. The investigators aim at comparing the analgesic efficacy of ultrasound-guided nerve block catheter compared with epidural analgesia for patients with knee OA who underwent unilateral total knee replacement.
postoperative pain and analgesic consumption between the first and the second surgery would be compared in patients undergoing staged bilateral total knee arthroplasty (BTKA).
The purpose of this study is to compare the efficiency of neuromuscular electrical stimulation and of resisted exercises on increasing quadriceps strength, decreasing pain and on recovering motor function of patients with knee osteoarthritis.
Treatment for early osteoarthritis (OA) of the knee is an increasing problem yet much of the research into OA, to date, concentrates on predisposition, genetic and cellular aspects and the treatment of late stage disease (arthroplasty). Clinicians reviewing patients with early OA have great difficulty in recommending an appropriate and efficacious intervention. The first line of treatment for patients with early OA is exercise, self-management and weight loss. These tools are suggested to minimize the need for higher risk treatments such as non-steroidal antiinflammatory drugs (NSAIDs) and surgery. Viscosupplementation using intra-articular injections of hyaluronan (Synvisc One) is a relatively new treatment. To date, the ideal patient for viscosupplementation has yet to be defined. It is not known whether incorporation of viscosupplementation into the overall clinical management will have beneficial influence for patients with early OA of the knee. This study will generate rigorous pilot data to assess the need and inform a larger randomized controlled trial (RCT) assessing the efficacy of viscosupplementation. The study will be a single blind randomised RCT. 60 patients with documented early OA will be randomised into one of two groupsÍž Group V will undergo "one shot" viscosupplementation using Synvisc One in addition to routine physiotherapy management for knee OA. Group No V (control) will have no viscosupplementation but will undergo similar routine management including physiotherapy management for knee OA. Outcome measures will include walking pain (The Western Ontario and McMaster Universities Arthritis Index-WOMAC), the overall WOMAC score, Oxford Knee Score (OKS), American Knee Society score (AKS), complications, activity level and patient satisfaction. Health economics will also be evaluated. Measurements will be recorded pre-intervention and at six months following treatment. The risks associated with viscosupplementation are minimal. Considering the limited resources currently available in health care, if the latter is shown to have higher effectiveness than physiotherapy alone, in addition to patient benefit, there will be important health economic implications.
The purpose of this pilot study is to investigate the efficacy and safety of autologous transplantation, under arthroscopy, of Bone Marrow Mesenchymal stem cells, using, with a cell separator, a fresh non-culture expanded Autologous Bone Marrow derived Mesenchymal Stem, mixed and activated with proteins scaffold in patient with Knee cartilage defects and osteoarthritis. Based on extensive preclinical investigations, the technology of using freshly isolated bone marrow mononuclear cells mixed with proteins seems safe and most effective for a one-step correction of cartilage defect and restoration of the osteochondral complex, because the same mixture can generate cartilage in the vasculature-free knee joint, and bone in the environment of bone defects.
The purpose of this study is to determine if the use of osteopathic manual therapy can influence the vascular supply to the knee, knee range of motion, balance and knee pain, in a group of subjects with knee osteoarthritis. It is also the objective of this study to determine if there is a difference between the osteopathic evaluation and the combination of an osteopathic evaluation and treatment.
The purpose of this study is to determine whether Minimal Invasive Surgery results in less postoperative pain and better mobilization than conventional technique in Unicompartmental Knee Arthroplasty, provided that both groups receive Local Infiltration Analgesia.
The aim of this study is to evaluate the outcome of specific repetitive biomechanical perturbation training on motor patterns. The first hypothesis of this project is that footwear derived biomechanical challenges will convey active and passive matching biomechanical responses (i.e. kinetic, kinematic and electromyographic) trough out the musculoskeletal kinematic chain. The second hypothesis of the project is that repetitive exposure to in-situ (trough out the gait sickle) introduction to a biomechanical stimulus would generate a process of motor learning thus conveying plasticity of existing locomotor patterns and gait strategies.
The purpose of the study is to evaluate the gait spatio-temporal parameters of patients with degenerative changes in the knee joint and to relate them with 2 questionares (WOMAC and SF-36).
