Filter by:Questionnaires are often irreplaceable tools of collection of information in research and in the clinical practice. Coupled with other measures, they can be simple complementary tools, but questionnaires are sometimes the only way to collect data, such as self-service efficacy. The objective of this study is a validation of the French translation of the ASES. To guarantee the comparability between the original version and the translated version, the translation of a questionnaire supposes two essential stages: a literal translation and an adaptation to the cultural context, to the habits of life and to the idioms of the target population. This new version will afterward be validated with patient's troop.
Total joint replacement is an efficacious treatment for osteoarthritis of hips and knees. Both total knee replacement (TKR) and total hip replacements (THR) have excellent implant survivorship. However, patient satisfaction is lower in TKR than THR. A possible cause of the discrepancy is the unnatural knee kinematics after TKR. Various implant designs have been developed to solve the problem. However, most of the designs are based on experimental data and not on in vivo kinematics. In this study, we will analyze the in vivo kinematics of the Global Medacta Knee Sphere (GMK Sphere) implant and compare it with a well documented design and implant (NexGen Cruciate Retaining (CR), Zimmer Biomet). We assume our study will contribute to the development of more satisfying knee implants.
Platelet-rich plasma (PRP) is an autologous product prepared from the patient's own blood, representing a powerful source of platelet-derived growth factors, particularly useful in the field of regenerative medicine. The active and sequential secretion of these growth factors induces different cell signaling cascades that activate angiogenesis, cell proliferation, cell differentiation, eventually leading to new matrix synthesis and tissue regeneration. The potential benefits from the use of PRP for the treatment of cartilage defects rely on a number of studies conducted in validated animal models or in vitro, demonstrating the ability of PRP to stimulate collagen production and proteoglycans synthesis, as well as the proliferation and differentiation of mesenchymal stem cells into chondrocytes. Additionally, an increasing number of clinical studies shows an improvement of symptoms, most especially pain, without any occurrence of serious adverse events. Hyaluronic acid (HA), as one of the major components of the synovial fluid surrounding the cartilage, assumes an important role in the viscoelastic properties of the articular cartilage, conferring its shock absorbing and lubricating functions. It was demonstrated that rheological properties of synovial fluid decrease with aging and in patients suffering from osteoarthritis. Nowadays, intra-articular injections of hyaluronic acid represent a well recommended therapeutic option to relieve osteoarthritic symptoms, conferring a mechanical action on joints structures, thus leading to reduced pain and improved joint function Based on these data, it seems reasonable to hypothesize that a combination of both PRP and hyaluronic acid could provide greater benefits compared to the administration of each product alone, as their effects on osteoarthritis improvement are based on different mechanisms of action. In fact, on one side PRP promotes cartilage regeneration, while on the other side the HA acts as 3-dimensional support mesh for PRP, providing optimal release of platelets growth factors, strengthening and extending in time the activity of PRP. Cellular MatrixTM is a CE-marked class III medical device manufactured by the Swiss company RegenLab SA. Cellular MatrixTM allows to prepare autologous PRP combined with a non-crosslinked hyaluronic acid in a safe, rapid manner and in a single step. The PRP/HA combination is intended to be injected intra-articularly, in order to relieve osteoarthritic symptoms and to improve joint mobility and function. Therefore, the PRP/HA combination might represent a novel therapeutic option for patient suffering from knee osteoarthritis. This study will evaluate whether the effects of a PRP/HA combination prepared with Cellular Matrix™, when injected intra-articularly for the treatment of mild to moderate knee osteoarthritis, are superior to those of a well-recognized hyaluronic acid treatment (Ostenil® Plus), on one hand, and to those of PRP alone, on the other hand.
The purpose of this study is to determine the clinical response to autologous bone marrow aspirate concentrate (BMAC) and platelet-rich plasma (PRP) injections for knee osteoarthritis with respect to pain, function, and quality of life at up to 1 year following the intervention. Specifically, the clinical response will be compared to baseline and a control group treated with a Gel-One® hyaluronate injection to the target knee.
The purpose of this study is to determine whether use of a pressure-detecting shoe improve can enhance favorable loading conditions at the knee.
Intra-articular hyaluronic acid injections, also known as viscosupplementation, are a treatment option for knee osteoarthritis that serves to restore the decreasing rheological properties of synovial fluid. KARTILAGE® CROSS is a visco-elastic gel of highly purified reticulated hyaluronic acid. It contains mannitol to provide an anti-oxidative action and to avoid hyaluronic acid depolymerization. Reticulation and mannitol increase the residency time of the product in the joint cavity then allowing a single injection in painful knee osteoarthritis patients. The US food and drugs administration (FDA) and European medicine agency (EMA), have recently published guidelines recommending a higher level of integration of biomarkers in the development and testing of new drugs to advance decision-making on dosing, time and treatment effect, trial design, and risk/benefit analysis. Biomarkers can be used not only in the process of drug development, but also in the future in assessment of individual patient's response to treatment. Several soluble biomarkers have been identified as potential candidates to predict or monitor the efficacy of intervention. Coll2-1, a degradation product of type II collagen, and Coll2-1NO2, a nitrated form of the Coll2-1 peptide have been studied in human osteoarthritis and entered the qualification process. Evidences demonstrated them to be pertinent and to be foresee as markers used for the diagnosis, the prognosis, the burden of disease and the monitoring of a treatment efficacy. The aim of this study was to provide with the first kinetic data regarding biomarkers in painful knee osteoarthritis patients treated with a new reticulated hyaluronic acid. The effects of the treatment were compared to those of saline solution. The primary endpoint was a specific osteoarthritis biomarker, Coll2-1. The secondary endpoints were the effects of the treatment or placebo on other biomarkers of osteoarthritis, its clinical efficacy and tolerance
Knee osteoarthritis (KOA) is a major public health problem among the elderly and is associated with considerable disability. A recent analysis of data indicated that about 35% of women and men aged 60 years and above had radiographic knee OA.Despite the high prevalence rate of OA, the treatment of OA is far from satisfactory. Acupuncture may be a promising treatment option for knee OA due to the effectiveness of the pain relief and the rarity of adverse effects. In order to get some more reliable data to confirm acupuncture effectiveness on KOA, a long-term follow up interventional study will be started to confirm the effects of long term for acupuncture treatment.
Patients with knee Osteoarthritis have high prevalence of pain , requiring ever more precise interventions in their management. This study aims to investigate the immediate effects of manual therapy and TENS on pain in patients with knee Osteoarthritis. Knowledge of best interventions favors reducing spending on health and safety for the patient.
Rehabilitation after total knee arthroplasty (TKA) should consider control of postoperative pain and swelling, protection of the healing graft, restoration of full range of motion symmetric to the contralateral knee, strengthening of the muscles that stabilize the knee, hip, and trunk, enhancing neuromuscular control, and a gradual progression to functional activities that are required for return to the normal daily life. The effects of concomitant injuries and surgical procedures must also be considered in planning an individualized rehabilitation program. However, it is still unclear regarding the optimal exercise prescription after TKA. In the current study, the investigators plan to develop an exercise protocol and evaluate the result in a multidisciplinary approach, i.e. bone mineral density assessment. The exercise prescription consisted of cyclic exercise, aerobic exercise and resistant training exercise for first, second and third year, respectively. Cyclic exercise is advantaged safety and effectiveness of hydraulic resistance equipment, as well as the exercise can be quantitatively determined. Aerobic exercise is privileged by the cardiopulmonary endurance improvement, along with muscle strengthening in the associated muscle groups. Resistance exercise is specified for the indicated muscle groups, especially knee extensors, flexors, ankle plantar flexor and dorsi flexor in TKA reconstructed patients. The investigators hypothesis that using this cyclic exercise process can improve the body composition, muscle strength, bone mass density, level of oxidative damage indicators, gait performance, quality of life, knee joint range of motion, function of cardiopulmonary and fitness. This project will establish the scientific basis for rehabilitation protocol involving knee surgery.
