PRP injections may help treat your chronic knee pain.
If you’re living with chronic knee pain, osteoarthritis, rotator cuff injury, or tendon inflammation, you’re not alone – and you don’t have to accept chronic knee pain as part of daily life. At our Norwest Sydney clinic, we offer non-surgical PRP (Platelet-Rich Plasma) injections designed to help you move more freely and live with less pain.
PRP works with your body’s natural healing processes, using concentrated platelets from your own blood to regenerate and lubricate the joints from within. Unlike cortisone injections, which often offer short-term relief, PRP is based on regenerative science and can provide pain relief that lasts up to nine months. If surgery isn’t an option—or you’re simply looking for a more affordable alternative with less downtime —book a consultation with Dr John Thorsell Itriago to see if PRP is right for you. Let’s help you get back to doing what you love, pain-free.
