Knee Osteoarthritis
Knee osteoarthritis is a degenerative joint disease where cartilage gradually wears away, causing pain, stiffness, inflammation and reduced mobility. As the condition progresses, bones may rub together, leading to increased inflammation and bone spur formation. PRP (Platelet-Rich Plasma) combined with Hyaluronic Acid (HA) offers a regenerative solution by addressing both tissue repair and joint lubrication.
PRP contains concentrated growth factors that stimulate cartilage nutrition and regeneration and reduce inflammation, while HA supplements the joint’s natural synovial fluid to improve cushioning and mobility. This dual approach is particularly effective for mild-to-moderate osteoarthritis (Grades 1-3), providing longer-lasting relief than cortisone or HA injections alone. Studies show PRP and Hyaluronic Acid injections can delay or even prevent the need for joint replacement surgery in some patients by preserving remaining cartilage and improving joint function.

Frequently Asked Questions
What is PRP and how does it help with knee osteoarthritis?
Platelet-Rich Plasma (PRP) is a concentrated solution derived from your own blood, rich in platelets and their associated growth factors. For knee osteoarthritis, a small blood sample is taken, processed to concentrate the platelets, and then injected into the affected knee joint. The goal of PRP is to leverage these natural growth factors to stimulate the body’s healing processes, reduce inflammation, alleviate pain, and potentially improve joint function by encouraging tissue repair within the knee. It’s considered a biological approach to managing osteoarthritis symptoms.
Am I a suitable candidate for PRP treatment for knee osteoarthritis in Australia?
PRP treatment for knee osteoarthritis is generally considered for individuals with mild to moderate osteoarthritis who are experiencing persistent pain and functional limitations, and who haven’t found sufficient relief from conventional treatments like pain medication, physical therapy, or hyaluronic acid injections. Your orthopaedic specialist will assess your specific condition, including the severity of your OA , your medical history, and discuss your goals to determine if PRP is a suitable option for you.
What can I expect during and after a PRP injection for knee osteoarthritis, and how long does it take to see results?
The procedure typically involves drawing blood, processing it using a centrifuge to separate the PRP, and then injecting the PRP into your knee joint, often with ultrasound guidance for precision. You might feel some mild discomfort during the injection. After the procedure, it’s common to experience some soreness, swelling, or stiffness in the knee for a few days. Your doctor will provide specific post-injection instructions, which usually include a period of reduced activity and avoiding anti-inflammatory medications (NSAIDs) for a certain time to allow the PRP to work effectively. While some patients may notice initial improvements in pain within a few weeks, the full benefits of PRP, as it works to regenerate and repair tissues, often become more apparent over 3 to 6 months. A structured rehabilitation program, including physical therapy, is often recommended to maximise outcomes.
How many PRP injections are typically required for knee osteoarthritis, and is it covered by Medicare or private health insurance in Australia?
The optimal number of PRP injections for knee osteoarthritis can vary. While some patients might experience significant relief from a single injection, many protocols involve a series of 2 to 4 injections, typically spaced a few weeks apart, to achieve optimal and sustained results. Your doctor will tailor the treatment plan to your individual needs and response. Regarding coverage in Australia, it’s important to note that PRP treatments for knee osteoarthritis are generally not covered by Medicare. This means the cost is usually an out-of-pocket expense.
