Knee osteoarthritis is a common condition that affects millions of people worldwide, causing pain, stiffness, and reduced mobility. While there is no actual cure for osteoarthritis, various treatment options aim to manage symptoms and improve quality of life.
Among those treatments are joint injections. In this blog, we will delve into four different injection therapies that are effective in managing knee osteoarthritis: cortisone, Platelet-Rich Plasma (PRP), hyaluronic acid, and Arthrosamid.
1. Cortisone Injections
Cortisone injections, also referred to as corticosteroid injections, play a crucial role in managing knee osteoarthritis. The primary mechanism of cortisone is its potent anti-inflammatory properties, which target the inflammation and swelling within the knee joint, thereby alleviating pain and improving mobility for individuals suffering from osteoarthritis. By directly delivering the medication into the affected joint, cortisone injections offer a more targeted and efficient approach compared to oral medications.
While cortisone injections can provide rapid and significant relief for acute flare-ups of osteoarthritis symptoms, it's essential to understand their limitations. These injections are typically recommended for short-term pain management, as their effects may diminish over time. Long-term use of cortisone injections may be associated with potential side effects, such as joint damage and weakening of surrounding tissues. Therefore, healthcare providers often advise using cortisone injections judiciously in pain flare-ups and in conjunction with other treatment modalities, such as physical therapy and lifestyle modifications, to optimise outcomes and minimise risks.
Patients considering cortisone injections for knee osteoarthritis should engage in a thorough discussion with their healthcare provider to weigh the benefits and risks based on their individual circumstances. Monitoring for any adverse reactions or changes in symptoms following the injection is crucial to ensure appropriate management and adjustment of treatment plans. While cortisone injections can be a valuable tool in the management of knee osteoarthritis, a comprehensive and personalised approach to care is essential for long-term joint health and overall well-being.
2. Platelet-Rich Plasma (PRP) Therapy
Platelet-Rich Plasma (PRP) therapy is a regenerative treatment that has garnered significant attention and popularity in knee osteoarthritis pain management. It involves harnessing the healing potential of the patient's own blood by isolating and concentrating platelets rich in growth factors essential for tissue repair and regeneration. The process of preparing PRP involves spinning the blood sample in a centrifuge to separate the platelets in z special tube, which are then carefully extracted and injected into the affected knee joint.
By delivering a concentrated dose of growth factors directly to the site of pathology, PRP therapy aims to kickstart the body's natural healing mechanisms, accelerate tissue repair, and mitigate inflammation within the knee joint. The growth factors present in PRP play a pivotal role in promoting the proliferation and differentiation of cells involved in cartilage regeneration, ultimately fostering the growth of healthy cartilage tissue.
While the scientific community continues to investigate and evaluate the efficacy of PRP therapy for knee osteoarthritis through clinical trials and research studies, the evidence is for efficacy in managing knee osteoarthritis is still limited and there is no consensus on the actual dose and optimum platelet count required to produce effective pain relief. However, anecdotal evidence and patient testimonials have highlighted promising outcomes. Many individuals with early mild osteoarthritis who have undergone PRP therapy have reported a noticeable reduction in pain levels, enhanced joint function, and an overall improvement in their quality of life. These positive results underscore the potential of PRP therapy as a non-invasive and holistic approach to managing knee osteoarthritis, offering hope to those seeking alternatives to traditional treatments.
3. Hyaluronic Acid Injections
Hyaluronic acid injections, also known as viscosupplementation, are an effective treatment approach for individuals suffering from knee osteoarthritis. This minimally invasive procedure involves the injection of a gel-like fluid directly into the knee joint, where hyaluronic acid acts as a natural lubricant and shock absorber. The synovial fluid in the knee joint naturally contains hyaluronic acid, which plays a crucial role in maintaining joint health by lubricating the joint surfaces and reducing friction during movement. In cases of knee osteoarthritis, the viscosity of the synovial fluid decreases, leading to increased joint pain, stiffness, and reduced mobility. By supplementing the joint with additional hyaluronic acid through injections, patients may experience improvements in joint function, reduced pain levels, and enhanced overall quality of life.
The goal of viscosupplementation is to restore the lubricating properties of the synovial fluid, thereby reducing friction within the joint and promoting smoother movement. It is important to note that the effectiveness of hyaluronic acid injections can vary from person to person. While some individuals may experience significant relief from pain and improved joint function after a single injection, others may require multiple injections over a period of time to achieve optimal results. The decision to pursue hyaluronic acid injections as a treatment option should be made in consultation with an experienced doctor provider, who can assess the individual's specific condition, especially the stage of osteoarthritis and recommend the most appropriate course of action.

4. Arthrosamid Treatment
Arthrosamid, a cutting-edge injection therapy, represents a significant advancement in the treatment of knee osteoarthritis. This innovative approach involves the precise delivery of a biocompatible hydrogel into the knee joint, with the primary objective of rejuvenating the viscoelastic properties of the synovial fluid. By doing so, Arthrosamid enhances cushioning and lubrication within the affected joint, thereby alleviating pain and improving overall joint function for a long period when compared to Hyaluronic acid, current studies shows over 3 years of sustained pain relief from a single injection.
Patients undergoing Arthrosamid treatment can expect not only symptomatic relief but also potential benefits in terms of disease progression. The hydrogel utilised in this therapy is carefully formulated to mimic the natural properties of healthy synovial fluid, creating an environment conducive to joint health and mobility. Through this mechanism, Arthrosamid not only targets the symptoms of osteoarthritis but also aims to slow down the degenerative processes that contribute to joint damage over time.
Although the efficacy of Arthrosamid in the long term requires further investigation, clinical studies have demonstrated promising outcomes. Patients receiving Arthrosamid injections have reported significant reductions in pain levels, accompanied by improvements in joint functionality and mobility. These positive results suggest that Arthrosamid has the potential to revolutionise the management of knee osteoarthritis, offering patients a novel and effective alternative treatment option to knee joint replacement.
