Filter by:Platelet-rich Plasma (PRP) is the most exploited biologic agents currently used for the treatment of osteoarthritis (OA) of different joints, in particular knee OA. In previous studies, it has been showed its potential to reduce pain and improve functional status in patients treated by simple intra-articular injections. However, there are several PRP formulation currently available in clinical use, and therefore it is very difficult to compare data coming from trials using different products. The most debated aspect concerning PRP formulation is the role of leukocytes, which might stimulate an early inflammatory response in the joint due to the release of metalloproteases and other pro-inflammatory cytokines. The investigators hypothesized that the presence of leukocytes in PRP could be clinically relevant in terms of outcome, so the present double blind randomized controlled trial was designed to compare leukocyte-rich and leukocyte-poor PRP injections for the treatment of knee OA. A power analysis has been performed for the primary endpoint of IKDC (International Knee Documentation Committee) subjective score improvement at the 12-month follow-up for PRP. From a pilot study, a standard deviation of 15.2 points was found. With an alpha error of 0.05, a beta error of 0.2 and a minimal clinically significant difference of 6.7 points corresponding at 1/3 of the documented mean improvement, the minimum sample size was 83 for each group. Considering a possible drop out of 15%, 96 patients per group are required for total 192 patients, selected according to well-defined inclusion criteria (see 'Eligibility criteria' section). Patients are then assigned to two different treatment groups, according to a randomization list. The first group of treatment consists of three weekly intra-articular injections of autologous leukocyte-rich PRP, whereas the second group of patients will be treated by three intra-articular injections of leukocyte-poor PRP. PRP will be obtained with the following procedure: a 300-ml autologous venous blood sample will undergo 2 centrifugations (the first at 1480 rpm for 6 minutes to separate erythrocytes, and a second at 3400 rpm for 15 minutes to concentrate platelets) to produced 20 ml of leukocyte-rich PRP. In case of patients allocated to receive leukocyte-poor PRP, a special filter will be then used to separate leukocytes and obtain leukocyte-poor PRP. The total amount of PRP will be divided into 4 small units of 5 ml each. One unit is sent to the laboratory for analysis of platelet concentration and for a quality test, 3 units are stored at -30° C. One week after the PRP production, the injective treatment starts, with 3 weekly injections. At the moment of the injection the syringe is properly covered to prevent the patient from discovering the substance he was receiving. After the injection, patients are sent home with instructions to limit the use of the leg for at least 24 h and to use cold therapy/ice on the affected area to relieve pain. During this period, the use of non-steroidal medication is forbidden. Patients are prospectively evaluated basally and at 2, 6, and 12 months of follow-up using clinical subjective scores and objective parameters to determine clinical outcome (see 'Outcome measure' section). Patient satisfaction and adverse events will be also reported. All the clinical evaluations are performed by a medical staff not involved in the injective procedure, in order to keep the study double blinded. At the end of the study, the nature of the injected substance is revealed to the patients.
Study is conducted to evaluate safety and efficacy in patients with osteoarthritis
This study plans to learn more about the effects of physical therapy (PT) following a total hip arthroplasty (THA). The purpose of this study is to compare standard of care PT after THA with a physical therapy program specifically designed to integrate targeted core and hip muscle strength and functional training.
A Double-Blind, Randomized, Placebo-Controlled, Parallel Group, Three-Arm, Multi-Site Study to Evaluate the Therapeutic Equivalence of Diclofenac Sodium Topical Gel 1% (Hi-Tech Pharmacal Co., Inc.) With Voltaren® Gel (Diclofenac Sodium Topical Gel) 1% (Novartis) in Patients With Osteoarthritis of the Knee
This is a retrospective, single-site observational study, designed to assess the clinical outcomes and collect safety data of GMK Revision knee system used for primary or revision total knee arthroplasty at minimum two years post-treatment.
The role of tobacco in osteoarthritis remains controversial. The Khoala cohort is the first multicenter French cohort of subjects with knee and / or hip osteoarthritis prevalent . It guarantees its methodology great representativeness and therefore an interesting material for the study of risk factors in the population. In addition, it should have little here Radiographs of hands for all its patients. It therefore has the opportunity to study a possible relationship between tobacco and hip osteoarthritis , knee and hand but also to study the relationship between tobacco and structural evolution of hip osteoarthritis and / or symptomatic knee.
This is sub-study to a randomised, double blind, placebo-controlled, parallel group, and single-centre trial investigating the effect of liraglutide on body weight and pain in overweight or obese patients with knee osteoarthritis (NCT02905864). In the parent trial patients will be subjected to a run-in diet intervention phase (week -8 to 0) including a low-calorie diet and dietetic counselling. At week 0 patients will be randomised to receive either liraglutide 3 mg or liraglutide 3 mg placebo as an add-on to dietetic guidance on re-introducing regular foods and a focus on continued motivation to engage in a healthy lifestyle. This sub-study of the parent trial only involves an additional assessment of skin auto fluorescence (AGE concentration) in the preallocation phase and in the main trial phase, i.e. from enrollment (defined as signature of informed consent) to treatment allocation (visits -Tx and T0 in the parent trial visit schedule) and from allocation to end of trial (visits T0 and T15 in the parent trial visit schedule).
This is a substudy to a randomised trial investigating the effect of liraglutide on body weight and pain in overweight or obese patients with knee osteoarthritis (NCT02905864). In the parent trial, patients will be subjected to an 8-week diet intervention phase including a low-calorie diet and dietetic counselling, after which.they will be randomised to receive either liraglutide 3 mg or liraglutide 3 mg placebo as an add-on to dietetic guidance on re-introducing regular foods and a focus on continued motivation to engage in a healthy lifestyle. This substudy aims to investigate any changes in physical activity associated with the initial 8-week weight loss intervention.
This study is a prospective, randomized, double-blind, placebo-controlled with 3 parallel-groups and multicenter trial in patients suffering from knee OA (osteoarthrosis). A first exploratory non comparative study (TILFLEXY002, NCT01909037, Henrotin et al., 2014 BMC Complementary and Alternative Medicine) evaluated the efficacy of FLEXOFYTOL® at the dose of 2x3 caps/day, during a 3-month period, in 22 patients suffering from knee OA, on the serum levels of cartilage-specific and inflammatory biomarkers, on the evaluation of pain and on the global patient assessment of disease activity. This study demonstrated a statistically significant decrease of sColl2-1 cartilage specific biomarker, an early decrease of the ultrasensitive C-reactive protein (CRP), an improvement of the global assessment of the disease by the patient as well as a good tolerance and compliance for the treatment. Results of this exploratory study are encouraging and justify the setup of a randomized, placebo-controlled double blind and dose-ranging trial.
The purpose of this study is to correlate functional outcomes and perioperative complications with tourniquet use during total knee arthroplasty.
