Platelet-rich plasma (PRP)
Platelet-rich plasma injections promote and accelerate the healing process providing significant improvement in the treatment of musculoskeletal injuries.
Platelets are small, colourless, disk-shaped cell fragments lacking a nucleus that is found in blood and play an imperative role in clot formation. They also have antimicrobial properties that support healing, infection control and the release of growth factors. These growth factors orchestrate the vital biological processes required for healing. Most importantly, as it relates to healing, platelets also release numerous growth factors, including PDGF, TGF-β, VEGF, and SDF-1α, that have been shown to orchestrate the key biological processes, including angiogenesis, inflammation resolution and tissue regeneration.
Growth factors are necessary to initiate tissue repair at a wound site. Growth factors derived from platelets are responsible for soft tissue repair, bone regeneration, development of new blood vessels and stimulation of the wound healing process. The concentrated platelets we use may help optimise the conditions for healing.
Plasma is the fluid component of blood that contains water, vital proteins, salts, minerals, sugars, fats, hormones and vitamins. Recently, plasma has been found to carry beneficial anti-inflammatory proteins such as Interleukin-1 Receptor Antagonist and Alpha-2-Macroglobulin. These proteins are known to “shut off” mechanisms that lead to degeneration and catabolic inflammation in the body.
The concept behind the clinical use of these blood components is to harness the natural biological ability of a patient’s blood―primarily platelets―which may help optimise the conditions for healing, improve inflammatory response, control infection and promote angiogenesis.
Platelets facilitate healing through the release of many growth factors actively involved in this process. Thus, PRP offers the physician an alternative to popular treatments, such as steroid injections. Such treatments provide short-term relief by masking symptoms such as pain and inflammation that are the result of an injury, rather than addressing the cause of the injury directly through the repair of damaged tissue.
Stem cells are at the core of the tissue regeneration process. They are required to rebuild and repair damaged tissue at an injury site. Platelets release several growth factors, such as SDF-1α, that function to induce migration of stem cells to the damaged tissue during the healing process. PRP provides these growth factors in high concentrations.
The PRP procedure is considered a safe treatment.
A small amount of the patient’s blood is taken, just as a blood test would be performed. The blood is then spun in a centrifuge to separate and concentrate the platelets. We then analyse the PRP solution to make sure our patients are receiving the appropriate cellular concentration and cellular counts for their condition. This plasma highly concentrated with platelets, and other cells are then injected into the site of injury or tissue degeneration under ultrasound guidance with precise, advanced, minimally invasive techniques.
Dr. Matti believes each patient and injury is different. We do not support the use of PRP as a “one size fits all” treatment. This is because PRP utilises your own blood, and this means there are variations between patients. We can individualise PRP treatments depending on the patient and the conditions we are treating. We incorporate ultrasound guidance to inject PRP to the affected areas accurately.
Indications for PRP Injections
Osteoarthritis, usually mild to moderate forms.
Refractory tendinosis, Examples:
– tennis elbow (lateral epicondylitis)
– golfers elbow (medial epicondylitis)
– patellar tendinosis
– Achilles tendinitis
-Shoulder pain due and Rotator cuff tears
PRP injections are designed to use platelets to trick your body into thinking that the affected area is injured, therefore triggering a regenerative response from your body. NSAID are hence stopped for 48 hours after the procedure.
Can be painful for up to 1 week, therefore often need regular pain relief.
Rest, ice and elevate limb for 48 hours.
Initially cease all activities for the first week but can resume normal day to day activities.
In the second week, can resume light exercises and progressively build back to normal exercise after 4 weeks.
Most patients see the most benefit, approximately 4-6 weeks post-injection.

I'm working on a travel story for Stuff about the things that have surprised returning Kiwis about New Zealand. If you have recently returned from overseas or know someone who has, it would be great to hear about the things that have stood out for you, for better or for worse. Whether it's to do with the weather, the cost of things, the public transport, the food, the housing, the people or something else entirely, we'd be keen to hear about it. Please remember that your comment may be included in the article, unless you say you don't want it to be. Thank you.
Its all set up. Come join us
