Effects and Safety of Intra-Articular Sodium Hyaluronate Injection for the Treatment of Ankle Osteoarthritis: A Prospective Clinical Trial

Effect of sodium hyaluronate combined with rehabilitation training on knee joint injury caused by golf

BACKGROUND

In high-intensity sports like golf, knee joints are prone to injury, leading to pain, limited mobility, and decreased quality of life. Traditional treatment methods typically involve rehabilitation exercises, but their effectiveness may be limited. In recent years, sodium hyaluronate has emerged as a widely used biomedical material in the treatment of joint diseases.

AIM

To explore the effect of sodium hyaluronate combined with rehabilitation training on pain degree, flexion range of motion and motor function of knee joint injured by golf.

METHODS

Eighty patients with knee joint injury caused by golf were randomly divided into control (group B) and observation group (group A). The group B was treated with rehabilitation training, and the group A was treated with sodium hyaluronate combined with rehabilitation training. The clinical efficacy, range of motion and function of knee joint, quality of life and inflammatory factors were compared.

RESULTS

The excellent and good rate of rehabilitation in the group A was raised than group B. At 6 weeks and 3 months after treatment, the range of motion of the two groups was raised than that before treatment, and that of the group A was raised than group B. After treatment, the scores of Lysholm and International Knee Documentation Committee (IKDC) in the group A were raised, and those in the group A were raised than group B. The VAS score of the two groups was reduced than that of the group B, and the SF-36 score of the group A was reduced than group B. The interleukin (IL)-1 β, IL-8 and tumor necrosis factor-α in the two groups were reduced, and those in the group A were reduced than group B.

CONCLUSION

Sodium hyaluronate combined with rehabilitation training has a good clinical effect in the treatment of patients with knee joint injury caused by golf, which relieve pain, maintain knee joint function and improve patients' life quality.

Hyaluronic Acid Viscosupplement Modulates Inflammatory Mediators in Chondrocyte and Macrophage Coculture via MAPK and NF-κB Signaling Pathways

Osteoarthritis (OA) is a chronic musculoskeletal disorder characterized by cartilage degeneration and synovial inflammation. Paracrine interactions between chondrocytes and macrophages play an essential role in the onset and progression of OA. In this study, in replicating the inflammatory response during OA pathogenesis, chondrocytes were treated with interleukin-1β (IL-1β), and macrophages were treated with lipopolysaccharide and interferon-γ. In addition, a coculture system was developed to simulate the biological situation in the joint. In this study, we examined the impact of hyaluronic acid (HA) viscosupplement, particularly Hyruan Plus, on chondrocytes and macrophages. Notably, this viscosupplement has demonstrated promising outcomes in reducing inflammation; however, the underlying mechanism of action remains elusive. The viscosupplement attenuated inflammation, showing an inhibitory effect on nitric oxide production, downregulating proinflammatory cytokines such as matrix metalloproteinases (MMP13 and MMP3), and upregulating the expression levels of type II collagen and aggrecan in chondrocytes. HA also reduced the expression level of inflammatory cytokines such as IL-1β, TNF-α, and IL-6 in macrophages, and HA exerted an overall protective effect by partially suppressing the MAPK pathway in chondrocytes and p65/NF-κB signaling in macrophages. Therefore, HA shows potential as a viscosupplement for treating arthritic joints.

Regulation of pain neurotransmitters and chondrocytes metabolism mediated by voltage-gated ion channels: A narrative review

Osteoarthritis (OA) is one of the leading causes of chronic pain and dysfunction. It is essential to comprehend the nature of pain and cartilage degeneration and its influencing factors on OA treatment. Voltage-gated ion channels (VGICs) are essential in chondrocytes and extracellular matrix (ECM) metabolism and regulate the pain neurotransmitters between the cartilage and the central nervous system. This narrative review focused primarily on the effects of VGICs regulating pain neurotransmitters and chondrocytes metabolism, and most studies have focused on voltage-sensitive calcium channels (VSCCs), voltage-gated sodium channels (VGSCs), acid-sensing ion channels (ASICs), voltage-gated potassium channels (VGKCs), voltage-gated chloride channels (VGCCs). Various ion channels coordinate to maintain the intracellular environment's homeostasis and jointly regulate metabolic and pain under normal circumstances. In the OA model, the ion channel transport of chondrocytes is abnormal, and calcium influx is increased, which leads to increased neuronal excitability. The changes in ion channels are strongly associated with the OA disease process and individual OA risk factors. Future studies should explore how VGICs affect the metabolism of chondrocytes and their surrounding tissues, which will help clinicians and pharmacists to develop more effective targeted drugs to alleviate the progression of OA disease.

Effects of Hyaluronic Acid With Intra-articular Corticosteroid Injections in the Management of Subtalar Post-traumatic Osteoarthritis - Randomized Comparative Trial

We investigated the potential of exogenous hyaluronic acid (HA) associated with corticosteroid injections to improve pain and function for the treatment of post-traumatic subtalar osteoarthritis, in comparison with isolated intra-articular corticosteroid. Twenty-five symptomatic participants (50 ± 8 years) with a minimum follow-up of 1 year after surgery for calcaneus fractures were enrolled. Participants were randomly assigned into a therapeutic group that underwent isolated corticosteroid intra-articular subtalar injection (Corticosteroid Group, n = 12) or a combination of HA plus corticosteroid (HA+C Group, n = 13). All participants underwent three repeated injections with intervals of 1 week. We assessed the visual analog scale of pain (VAS) and the AOFAS scores at 4 moments: before treatment (pre), 4-, 12-, and 24-weeks following the last injection. HA+C Group showed lower VAS at the 12th (p = .003) and 24th weeks (p = .003) and greater AOFAS at the 4th (p = 0.040), 12th (p = .014), and 24th weeks (p = .021), in comparison to Corticosteroid Group. We observed a reduction in VAS in the Corticosteroid Group only at the 4th week (p = .007), compared with pretreatment values. In the HA+C Group, VAS presented lower levels at the 4- (p < .001), 12- (p < .001), and 24 weeks (p < .001). In the Corticosteroid Group, participants presented higher AOFAS score only at the 4th week (p < .001), while in the HA+C Group, the AOFAS scores were greater at the 4th, 12th, and 24th weeks compared to baseline (p < .001). The combination of exogenous HA and corticosteroid showed greater and longer analgesic effects and function improvement in comparison with isolated intra-articular corticosteroids.
