It was previously proved an association of TGF-β1 and PDGF-BB with the pathogenesis of osteoarthritis (OA) by experiments of OA animal models. In this study, we aimed to determine whether serum concentrations of TGF-β1, PDGF-BB and CTX-1 were related to the knee OA. knee OA cases were collected from the first affiliated hospital of Shihezi university and healthy controls were recruited from the community. The severity of knee OA was defined as kellgren-lawrence (K-L) classification criteria.Serum levels of chemical biomarkers were compared between knee OA cases and controls or among K-L grade 2 to grade 4 groups. The serum concentrations of the TGF-β1, PDGF-BB and CTX-1 were determined by ELISA .
The purpose of this study is to compare the clinical and functional outcomes of patients with mild to moderate arthroscopically confirmed osteoarthritis between the following two groups: 1. Partial fat pad harvest with Adipose-Derived Stem Cell (ADSC) transplantation with standard arthroscopic treatment consisting of: partial meniscectomy, cartilage stabilization, loose body removal and selective synovectomy. 2. Standard arthroscopic treatment (above) with out cell transplant.
The investigators plan to undertake a rigorous multicentre randomised controlled trial, comparing acupuncture on sensitized acupoints versus non-sensitized acupoints, to test if acupuncture on sensitized acupoints may result in improved treatment outcomes in patients with Knee osteoarthritis (KOA).
The purpose of this study is to evaluate the efficacy and safety of intra-articular injection of autologous adipose tissue derived mesenchymal stem cells compared after high tibial osteotomy to negative control in the osteoarthritis patients
Knee osteoarthritis is one of the most common pathologies in old people, and the leading cause of pain and disability. Symptoms include joint pain, stiffness, limited mobility, functional impairment and proprioceptive deficit. When conservative treatments fail to control these symptoms, a total knee replacement (TKR) is the chosen treatment, mainly because of its efficacy on pain relief. In recent decades, this surgical procedure has been soared, and it has also aroused the interest of researches about the patients' outcomes after surgery. Despite the TKR results in good reported outcomes, after surgery patients may manifest persistent pain and problems affecting to their functionality, stability, walking speed, proprioception, motor control, risk of falling and therefore to their quality of life. In more than a third of the cases, those deficiencies may be extended after surgery from six months to one year, when subjects use to achieve the plateau functional values. Traditional rehabilitation programs have been usually focused on improving muscle strength of the lower limbs as well as the functionality with specific exercises to achieve this purpose, and to a lesser extent on balance and proprioception exercises. Evidence supports this approach. Yet, task-oriented rehabilitation focusing on balance enhancement may be one of the most important factors for a complete rehabilitation, since benefits of proprioceptive and balance trainings may range from better stability and motor control, improvements in both static and dynamic balance and enhanced functionality. Indeed, recent studies have shown that the combination of traditional functional rehabilitation together with balance training may help to restore functional deficits to a larger extent than usual therapy, and based on a systematic review published (Moutzori, 2015) and in our previous works (Roig, 2016), sensori-motor training is an acceptable adjust to usual physiotherapy care . Looking into the effect of preoperative trainings or education before TKR surgery, it is aimed at improving the physical function, but also managing the expectations of the surgery for a better recovery. There is from low to moderate evidence about the effects of TKR pre-interventional training programs, and some authors have argued that the effects are too small to be consider clinically relevant. In general, the preoperative program is usually focused on functional and strengthening exercises. Despite of proprioception is used in the clinical practice for the prevention and recovery of many orthopedics injuries, the amount of evidence about the effects of proprioceptive training programs for knee and hip replacement is not large, few works compares pre-habilitation and post-rehabilitation programs, and there is not systematically reviewed evidence reporting the efficacy of balance and proprioceptive pre-interventional training programs. In this framework, this aimed at evaluating the effects of specific-task oriented proprioceptive and balance training programs when conducted by patients undergoing TKR before and after surgery, and will compare these effects to the outcomes achieved with traditional strength-functional programs, as well as to no specific prehabilitation training.
BACKGROUND: Despite the prevalence of patellofemoral ostearthritis (OA), this joint has received relatively little attention in the OA literature and there are few treatment options for individuals with patellofemoral OA. Patellar misalignment is associated with radiographic progression patellofemoral OA and symptoms and in magnetic resonance imaging (MRI), to cartilage loss measurements and bone marrow lesions. The hypothesis is that the correction of the patella disorder using strategies such as bracing or adhesive bandages can handle the symptoms and progression of OA. OBJECTIVE: To compare the effect of a brace designed to stabilize the patellofemoral joint compared with a neoprene sleeve with kneecap opening in patients with patellofemoral OA. METHODS: Fifty-two patients with patellofemoral OA and co-morbidities (Two or more of: overweight or obesity, hyperglycemia, dyslipidemia, hyperuricemia, high blood pressure) will be divided into two groups according to the knee brace that will receive: Functional Bracing patellofemoral (group 1) and neoprene knee sleeve with patella opening (group 2). Both groups will be oriented on the clinical treatment of osteoarthritis and metabolic syndrome and asked to do daily exercises in addition to reporting the daily consumption of drugs a month before placing the orthotics up to three months after placing it. They will be evaluated with the questionnaires WOMAC and Lequesne, and asked to perform the five-times-sit-to-stand-test, Timed-up-and-go (TUG) and the six-minute walk test in the moments immediately prior to placement of the brace, with one, three and after 12 months bracing.
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, patients' satisfaction is lower in TKR than THR. A possible cause of the discrepancy is the unnatural knee kinematics after TKR. Various implants designs have been developed to solve the problem. However, most of their designs are based on experimental data and little has been studied about their kinematics in vivo. 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 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 MatrixTM when injected intra-articularly for the treatment of mild to moderate knee osteoarthritis, are superior in terms of mechanism of action, when compared to a well-recognized hyaluronic acid treatment (Ostenil® Plus).
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.
