What is Platelet Rich Plasma (PRP) Therapy?

Platelet Rich Plasma therapy is a regenerative medicine treatment that uses a concentrated solution of your own platelets to promote healing in injured or damaged tissues. Platelets are blood cells that play a crucial role in your body’s natural healing process, containing growth factors and proteins essential for tissue repair.

During PRP therapy, a small amount of your blood is drawn and processed using a centrifuge to separate and concentrate the platelets. This creates a solution with a higher platelet concentration than normal blood. When injected into injured areas, these concentrated platelets release growth factors that stimulate and enhance your body’s natural healing processes.

The treatment works by accelerating tissue regeneration, reducing inflammation, and promoting the formation of new healthy cells. PRP injections have been studied for a range of musculoskeletal conditions, including certain acute muscle, ligament, and tendon injuries. As with any regenerative treatment, evidence continues to develop, and suitability is assessed on a case-by-case basis by your orthopaedic surgeon.

Because PRP uses your own blood, the risk of allergic reactions or disease transmission is very low, making it suitable for many patients.

Ideal Candidates

Patients with acute muscle or ligament injuries who are being treated non-surgically
Athletes with acute ligament or muscle injuries who are being managed non-surgically, including select cases of partial ACL injury.
Patients who have not achieved sufficient improvement with conventional treatments
Those seeking to avoid or delay surgical intervention
Individuals with certain acute soft tissue injuries, as assessed by your orthopaedic surgeon
Generally healthy individuals with good overall healing capacity
Non-smokers or those willing to quit during treatment

Contraindications

Active infections or fever
Blood disorders or platelet dysfunction syndromes
Patients on anticoagulation therapy
Active cancer or history of certain cancers
Severe anaemia or low platelet counts
Pregnancy or breastfeeding
Immunosuppression or autoimmune disorders
Certain skin diseases at the injection site

A thorough medical evaluation is essential to determine whether PRP therapy is suitable. The patient’s medical history, current medications, and treatment goals should be reviewed to confirm that PRP injections are appropriate.

Treatment Techniques & Approaches

Standard PRP Preparation

PRP treatment begins with a blood sample taken from the patient. The sample is processed in a centrifuge to separate red blood cells, platelet-poor plasma, and the platelet-rich layer. The resulting concentrated PRP is then prepared for injection into the target tissue to support healing and regeneration.

LR-PRP vs LP-PRP

PRP preparations can vary based on their white blood cell content. LR-PRP includes white blood cells along with platelets, which may influence the body’s inflammatory response. LP-PRP primarily contains platelets and is sometimes chosen for conditions where limiting inflammation is preferred.

Injection Techniques

PRP can be administered through various injection techniques depending on the treatment area. Ultrasound guidance is often used for precise delivery to tendons, ligaments, or joints.

Technology & Equipment Used

PRP treatment uses specialised centrifuges and collection kits designed to optimise platelet concentration and viability. Some systems include proprietary separation gels or filters to improve the purity of the final preparation. Ultrasounds are frequently used to guide injections and ensure accurate placement of the PRP solution.

The Treatment Process

Pre-Treatment Preparation

Before your PRP injection appointment, you’ll need to stop taking anti-inflammatory medications (NSAIDs) for 5-7 days, as these can interfere with platelet function. Maintaining good hydration in the days leading up to the treatment is recommended, and alcohol should be avoided for a few days prior. If sedation is planned, arrange suitable transport.

On the day of treatment, eat a normal meal to reduce the risk of lightheadedness during blood draw. Wear comfortable clothing that allows easy access to the treatment area. Inform your doctor of any recent illnesses or changes in medications.

During the Procedure

The PRP injection process begins with blood sample, usually taken from the arm. The blood sample is then placed in a centrifuge to separate the components. While this occurs, the injection site is disinfected and made ready for the procedure.

Ultrasound guidance may be used to ensure precise placement of the PRP. Local anaesthetic can be applied to minimise discomfort. The concentrated PRP is then injected into the targeted area using a fine needle.

Most patients experience only mild discomfort during the injection, similar to any other injection. Some areas may be more sensitive than others.

Immediate Post-Treatment

After the injection, patients are observed briefly for any immediate reactions. Ice may be applied to manage swelling, but only as recommended to avoid affecting the healing response. Most patients can leave the clinic shortly afterwards.

Initial soreness and swelling at the injection site are normal and expected. Your doctor will provide specific instructions based on your treatment area and condition. Most patients can return home immediately with minimal restrictions.

Recovery & Aftercare

First 24-48 Hours

Expect mild to moderate pain and swelling at the injection site, which is a normal part of the healing. This inflammatory response is beneficial as it indicates the healing has begun. Apply ice for 10-15 minutes several times daily to manage discomfort. Avoid NSAIDs and use paracetamol for pain relief if needed.

Rest the treated area and avoid strenuous activities. For joint injections, follow guidance on limiting weight-bearing. Keep the injection site clean and dry, and monitor for signs of infection such as increasing redness, warmth, or fever.
First Week

Continue protecting the treated area from excessive stress. Gentle range-of-motion exercises may be started as advised. Gradually resume daily activities but avoid high-impact exercise or heavy lifting.

You may notice initial improvement in symptoms, though the full effects typically develop over time. Attend your follow-up appointment to evaluate the response and adjust your recovery plan. Some patients may experience a temporary increase in symptoms around days 3-7 before improvement begins.
Long-term Recovery

Full benefits from PRP injections typically develop over 3-6 months as tissue regeneration occurs. Physiotherapy often begins 2-4 weeks post-injection to optimise outcomes. Most patients can return to normal activities within 4-6 weeks, with athletic activities resumed gradually.

Some conditions may require multiple PRP sessions spaced a few weeks apart. Following recommended recovery protocols and addressing any underlying issues can help support the healing process.

Benefits of PRP Injections

Platelet Rich Plasma (PRP) therapy leverages your body’s natural healing processes to support tissue repair and regeneration. For appropriate candidates, PRP injections may help support recovery in the non-surgical treatment of acute muscle and ligament injuries. It can also aid in the biological augmentation of acute Achilles tendon repairs, promoting the body’s natural tissue healing.

PRP uses your own blood, which minimises the risk of allergic reactions or rejection. The procedure is minimally invasive with little downtime, allowing most patients to resume daily activities quickly. Your orthopaedic surgeon will discuss whether PRP is an appropriate option for your specific condition, based on current clinical guidelines and regulatory requirements.

Common Side Effects

Most patients experience temporary pain and swelling at the injection site lasting 3-7 days. This is a normal part of the healing response. Bruising may occur, and some stiffness in the treated area is common during the first week.

Mild headaches or fatigue can also occur on the day of treatment, usually resolving within 24 hours with rest and hydration.

Rare Complications

Infection at the injection site is rare but possible. Signs include increasing pain, redness, warmth, or fever developing days after the injection. Nerve irritation or injury is rare when performed by experienced physicians using proper technique.

Allergic reactions are highly unlikely, as PRP uses your own blood. Reactions to local anaesthetic or cleaning solutions are possible. In some cases, patients may not notice improvement, particularly in severe or long-standing conditions.

Proper sterile technique, accurate injection placement, and appropriate patient selection minimise these risks. PRP injections should be administered by clinicians trained in the procedure to ensure correct technique and safety.

Cost Considerations

The cost of PRP injections depends on factors such as the treatment area, number of injections needed, and whether imaging guidance is required. Larger joints or multiple areas treated simultaneously typically cost more than single, small area treatments.

Fees typically cover the blood draw, processing, and injection procedure. Additional charges may apply for the initial consultation, imaging studies, or follow-up visits. The use of ultrasound guidance, while improving accuracy, may add to the overall cost.

PRP injections are generally self-funded and are typically not covered by MediSave or MediShield Life. Your clinic staff can advise on payment options during your consultation.

During your consultation, you will receive a detailed breakdown of all associated costs specific to your treatment plan.

Frequently Asked Questions

How long does a PRP injection procedure take to perform?

The entire PRP injection process typically takes 30-60 minutes from start to finish. This includes blood collection, centrifuge processing, and the injection itself. Additional time may be needed if ultrasound guidance is used or multiple areas are being treated.

When will I start seeing results from PRP therapy?

Results from PRP injections develop gradually as your body undergoes the healing process. Some patients notice initial improvement in pain and function within 2-4 weeks, while more noticeable effects often develop over 3-6 months. The exact timeline depends on the condition being treated and individual healing response.

How many PRP injection sessions will I need?

The number of PRP sessions varies depending on your condition and response to treatment. Many patients achieve good results with 1-3 injections spaced 4-6 weeks apart. Acute injuries may respond to a single injection or a series depending on the severity. Follow-up assessments after each session help determine whether additional treatments are appropriate. Some patients may choose maintenance injections every 6–12 months.

Is PRP therapy painful?

Most patients experience only mild to moderate discomfort during PRP injections, similar to any other routine injections. The blood draw feels like standard lab work, and the injection site may experience brief pressure or stinging. Local anaesthetic can be applied to reduce discomfort. Post-injection soreness is common and expected for 3-7 days as part of the healing response. This is typically well-managed with ice, rest, and paracetamol if needed.

Can I exercise after PRP injections?

Exercise restrictions after PRP injections depend on the treatment area and your specific condition. Generally, you should avoid strenuous activities for the first 48-72 hours to allow the initial healing response to begin. Light activities and gentle range-of-motion exercises may be encouraged after the first few days. Most patients can gradually return to exercise over 2-4 weeks, with full activities resumed by 4-6 weeks. Our doctor will provide specific guidelines based on your treatment.

How is PRP different from cortisone injections?

PRP and cortisone injections work differently. Cortisone provides rapid pain relief by reducing inflammation but does not stimulate tissue repair and may impair healing if used repeatedly. PRP encourages the body’s natural healing processes to repair damaged tissue, although improvements take longer to appear. Cortisone effects typically last 3–6 months, whereas PRP addresses tissue repair rather than just alleviating symptoms.

Are there any age restrictions for PRP therapy?

There are no strict age limits, but suitability depends on overall health and healing capacity. Younger patients often have stronger healing responses, but many older adults also benefit. The key factors are having adequate platelet counts and good general health. PRP use in children is less common and requires special consideration. Individual assessment ensures the treatment is appropriate.

Conclusion

Platelet Rich Plasma (PRP) injections offer a minimally invasive regenerative treatment that supports the body’s natural healing processes. By delivering concentrated growth factors directly to injured or damaged tissues, PRP therapy provides a treatment option for select musculoskeletal conditions, within the scope permitted under current healthcare regulations. Suitability is determined individually, based on your specific condition and clinical assessment.
