BACKGROUND: Hyaluronic acid injection has been reported to decrease pain compared with baseline levels in knee joint osteoarthritis. Hylan G-F 20 is distinguished from the other products by its chemical structure and relatively higher molecular weight. Many trials have compared hylan G-F 20 and low molecular weight hyaluronic acids (LMWHAs); however, their relative efficacy and safety are still debated. OBJECTIVE: The aim was to compare the effectiveness and safety of intra-articular injection of hylan G-F 20 and LMWHA in the treatment of knee joint osteoarthritis...

BACKGROUND: Intra-articular injection of hyaluronic acid (HA) for knee osteoarthritis (OA) effectively reduces pain and delays total knee replacement (TKR) surgery; however, little is known about relative differences in clinical and cost outcomes among different HA products. OBJECTIVE: To compare disease-specific costs and risk of TKR among patients receiving different HA treatments in a commercially insured cohort of patients with knee OA in the USA. METHOD: Retrospective analyses using IMS Health's PharMetrics Plus Health Plan Claims Database were conducted by identifying knee OA patients with claims indicating initiation of HA treatment at an 'index date' during the selection period (2007-2010)...

INTRODUCTION: Osteoarthritis (OA), as one of the leading causes of disability, decreases the quality of life for those suffering from the disease and creates a substantial financial burden. Intra-articular hyaluronic acid (HA) can provide relief from the symptoms of OA and multiple HA products are prescribed. The purpose of this study is to examine the single payer cost-effectiveness of various HA products in the treatment of knee OA. METHODS: A single payer economic evaluation was conducted comparing Synvisc(®) (Sanofi, USA), Durolane(®) (Bioventus, USA), Hyalgan(®) (Fidia Pharma Inc...

BACKGROUND: Osteoarthritis (OA) is characterized by progressive loss of cartilage in joints, and is a major cause of pain and disability, and imposes significant health care expense. New therapies are being developed to treat the symptomatic effect of OA, one of which is intra-articular injection of viscosupplementations of different forms of hyaluronic acid (HA). The current study evaluates the chemical exchange saturation transfer (CEST) effect from two popular viscosupplementations [Hylan gf-20 (Synvisc) and hyaluronan (Orthovisc)] by targeting the exchangeable hydroxyl protons present on these molecules (ViscoCEST)...

Osteoarthritis (OA) can be a debilitating degenerative disease and is the most common form of arthritic disease. There is a general consensus that current nonsurgical therapies are insufficient for younger OA sufferers who are not candidates for knee arthroplasties. Adipose-derived mesenchymal stem cells (MSCs) therapy for the treatment of OA can slow disease progression and lead to neocartilage formation. The mechanism of action is secretion driven. Current clinical preparations from adipose tissue for the treatment of OA include autologous stromal vascular fraction (SVF), SVF plus mature adipocytes, and culture-purified MSCs...

Local tissue reactivity to intra-articular injections of hyaluronic acid hylan G-F 20 (Synvisc) has been described. We used a murine biocompatibility model to study the inflammatory response to Synvisc after a single bolus injection versus the traditional three shot series of injections. Air pouches were established subcutaneously in BALB/c mice, which were injected with phosphate-buffered saline (PBS), 5 mg ultra-high molecular weight polyethylene particles (to simulate synthetic joint wear debris, positive control), 0...

Knee pain is commonly seen in orthopedic and rehabilitation outpatient clinical settings, and in the aging population. Bursitis of the knee joint, especially when the volume of the synovial fluid is large enough, can compress and distend the nearby soft tissues, causing pain in the knee joint. Out of all the bursae surrounding the knee joint, supra-patellar bursitis is most often associated with knee pain. Treatment strategies in managing supra-patellar bursitis include the aspiration of joint synovial fluid and then followed by steroid injection into the bursa...

Osteoarthritic (OA) knee pain can be successfully treated with hylan G-F 20 (Synvisc, Sanofi Biosurgery, Cambridge, MA) with few local adverse events. However, a few studies have identified hyaluronate positive (HA+) granulomas in the synovial tissue of patients treated with hylan G-F 20 raising the question of their relationship and clinical significance. To understand the potential relationship of HA+ granulomas with the occurrence of acute local reactions (ALRs), we evaluated the synovial tissue of OA patients undergoing total knee replacement that had previously been treated with hylan G-F 20 (n = 101) or had not been treated (n = 20)...

Hyaluronic acid (HA) is a glycosaminoglycan with diverse biomedical applications including viscosupplementation of synovial fluid for the treatment osteoarthritis. Current HA viscosupplements such as Synvisc, Orthovisc, and Hyalgan have shown positive effects of reducing pain and improving joint function. The therapeutic efficacy, however, is highly transient, and these viscous fluids suffer from poor injectability. HA nanoparticles were found to modify the rheological properties of a model of the HA viscosupplement Orthovisc...

A large-molecular-weight polyanion is found to possess lubricating properties for cartilage. The polyanion, sodium poly(7-oxanorbornene-2-carboxylate), is synthesized by ring-opening metathesis polymerization of methyl 5-oxanorbornene-2-carboxylate. When dissolved in aqueous solution and applied to the surface of human cartilage it reduces the friction at the interface and acts as a lubricant. Its performance is similar to that of synovial fluid and superior to those of saline and Synvisc in an ex vivo human cartilage plug-on-plug model...

Osteoarthritis is characterized by progressive articular cartilage degeneration, changes in subchondral bone and synovial inflammation, leading to pain and disability. Viscosupplementation with hyaluronic acid has been widely investigated due to the viscoelastic properties of this compound to manage pain improving the ability to perform daily activities in patients affected by osteoarthritis. In the present study we investigated the clinical effectiveness of viscosupplementation with a new highly cross-linked hyaluronic acid, Variofill, in patients affected by bilateral knee osteoarthritis in comparison with the widely used Synvisc...
