PURPOSE: To analyze the early outcomes of viscosupplementation in patients with severe knee osteoarthritis. METHOD: A randomized, double-blind clinical trial of 143 knees divided into three groups: Group 1 - intra-articular injection of triamcinolone; Group 2 - hylan GF20; and Group 3 - triamcinolone + hylan GF20. Outcomes were evaluated using Lysholm and KSS scores before treatment and after one, three and six months. RESULTS: Within-group comparisons revealed improvements in Lysholm scores in all groups in the one month evaluation relative to pre-treatment levels (p < 0...

Hyaluronic acid (HA) has been a treatment modality for patients with knee osteoarthritis (OA) for many years now. Since HA was first introduced for the treatment of painful knee OA, much has been elucidated regarding both the etiology of this disease and the mechanisms by which HA may mitigate joint pain and tissue destruction. The objectives of this article are to (1) describe the etiology and pathophysiology of OA including both what is known about the genetics and biochemistry, (2) describe the role of HA on disease progression, (3) detail the antinociceptive and anti-inflammatory actions of HA in OA, and (4) present evidence of disease-modifying effects of HA in the preservation and restoration of the extracellular matrix...

A microporous hydrogel was developed using sodium alginate (alg) and 4-aminosalicylic acid (4-ASA). The synthesized hydrogel was characterized using various analytical techniques such as Fourier transform infrared spectroscopy (FTIR), Carbon-13 nuclear magnetic resonance ((13)C-NMR), X-ray powder diffraction (XRD), scanning electron microscopy (SEM), and differential scanning calorimetry (DSC). Additonal carboxyl and hydroxyl functional groups of 4-ASA provided significant lubrication and stress-triggered sol-gel transition to the conjugated hydrogel...

BACKGROUND: To investigate the effect of intra-articular injection of Chitosan (Cs) added to hyaluronic acid (HA) on subchondral bone during osteoarthritis (OA), microarchitectural parameters and mineral density were measured in a rabbit model of early OA. A novel hybrid hydrogel adding reacetylated Cs of fungal origin to HA was compared to high molecular weight HA commercial formulation. METHOD: Eighteen rabbits underwent unilateral anterior cruciate ligament transection (ACLT) and were divided into three groups (Saline-group, HA-group and Hybrid-group) depending on the intra-articular injection compound...

Background In the management of knee osteoarthritis (OA), patient-reported-outcomes (PROs) are being developed for relevant assessment of pain. The patient acceptable symptom state (PASS) is a relevant cutoff, which allows classifying patients as being in "an acceptable state" or not. Viscosupplementation is a therapeutic modality widely used in patients with knee OA that many patients are satisfied with despite meta-analyses give conflicting results. Objectives To compare, 6 months after knee viscosupplementation, the percentage of patients who reached the PASS threshold (PASS +) with that obtained from other PROs...

Hylan G-F 20 (Synvisc-One) is a hyaluronic acid derivative used for viscosupplementation of synovial fluid in osteoarthritic joints. Injection of hylan G-F 20 is Federal Drug Administration approved for use in knee osteoarthritis and is generally well tolerated with few reported adverse effects, the most common being local pain or swelling. We present the case of a 72-year-old man with bilateral, diffuse, joint pain and swelling with elevated inflammatory markers suggestive of a systemic inflammatory polyarthropathy that developed acutely 2 days after lumbar zygapophyseal joint injection with hylan G-F 20...

Viscosupplementation with intra-articular injections of hyaluronic acid is recommended as a second line treatment for knee OA, after failure of non-pharmacological modalities and usual pain killers. Nevertheless there is still controversies regarding clinical relevance of its effects. Research is looking at the best means to improve the performance of viscosupplementation in order to obtain a faster, more sustainable and more marked effect. Antioxidants have been assessed in combination with hyaluronic acid because the injected hyaluronate is rapidly degraded by the reactive oxygen species present in large amounts in the OA synovial fluid, limiting its residence time into the joint...

INTRODUCTION: Most clinical studies and basic research document viscosupplementation (VS) in terms of effectiveness and safety, but only a few highlight its molecular mechanisms of action. Besides, there is generally focus on hyaluronic acid (HA) as being the most relevant polysaccharide to reach the clinical endpoints, attributing its effect mainly to its unique viscoelastic properties, related to a high-molecular weight and gel formulation. Usually, studies do not approach the possible biological pathways where HA may interfere, and there is a lack of reports on other biocompatible polysaccharides that could be of use in VS...

REVIEW
Sourav K Poddar, Luke Widstrom
Nonoperative options for articular cartilage injury are pervasive but have not shown to be curative. Recommendations for low-impact exercise and weight loss provide benefit and are a foundation for the treatment of osteoarthritis. Judicious use of NSAIDs and acetaminophen can be appropriate for pain management. Topical NSAIDs may be a treatment option with fewer side effects than its oral counterpart. Additionally, viscosupplementation injections are useful for mild to moderate knee osteoarthritis, whereas short-term pain relief is provided by intra-articular corticosteroid injections...

The aim of this study was to evaluate the morphological, microstructural, and mechanical effects of a viscosupplementation therapy on rabbit menisci at an early stage of osteoarthritis (OA). Anterior cruciate ligament transection (ACLT) was performed in twelve male New-Zealand White rabbits on the right knee joint. Six of these twelve rabbits received a mono intra-articular injection of high molecular weight hyaluronic acid (HA) two weeks after ACLT. Six additional healthy rabbits served as controls. Medial menisci were removed from all right knees (n=18) six weeks after ACLT and were graded macroscopically...

BACKGROUND: Viscosupplementation is a symptomatic treatment of the knee osteoarthritis based on the intra-articular injection of hyaluronic acid (IAHA). Although many studies have investigated its effect on symptoms, few clinical studies have focused on its effects on biologicals markers of cartilage metabolism. In this study, we assessed the effect of an intra-articular injection of a reticulated hyaluronic acid compound on the level of a specific biomarker of type II collagen degradation...

Purpose: Controversies remain surrounding the choice of hyaluronic acid products and patient selection. A study was conducted to report the long-term survivorship of intra-articular injection effect of high molecular weight hyaluronic preparation hylan GF-20 (Synvisc-One) for patients with symptomatic knee osteoarthritis. Materials and Methods: A retrospective observational analysis of a single therapeutic series was carried out. The analysis was conducted to determine therapeutic effect survivorship taking arthroplasty and any other surgical interventions as endpoint results...

Viscosupplementation is a therapeutic approach for osteoarthritis treatment, where the synovial fluid, the natural lubricant of the joints, is replaced by viscoelastic solutions with rheological properties comparable or better than the starting material. This study presents the development of an innovative platform for viscosupplementation, based on the optimization of polysaccharide-based colloidal hydrogel, aiming to reduce on-site enzyme degradation and enhance the possibility of hyaluronic acid substitution with alternative biomaterials...

Hip arthropathy in haemophilic patients is disabling for hip and other common target joints. Even if bleedings in the hip are not frequent, femoroacetabular alterations may affect the functional ability of patients at a very young age. A haematologic prophylaxis combined with an adequate lifestyle and regular and low-traumatic physical activity are the keys to preventing such arthropathy. In the early stages of arthropathy, anti-inflammatory drugs and physical therapy may be sufficient to limit its progression...

INTRODUCTION: Osteoarthritis of the trapeziometacarpal (TMC) joint of the thumb - also known as rhizarthrosis - is painful and has a significant impact on quality of life. Intra-articular injection of hyaluronic acid may potentially meet the need for effective, minimally invasive intervention in patients not responding adequately to initial treatment. We aimed to confirm the safety and effectiveness of viscosupplementation with Durolane (NASHA nonanimal hyaluronic acid) in rhizarthrosis...
