Platelet-Rich Plasma (PRP) Injections in Ottawa

Platelet-rich plasma (PRP) is a biologic injection therapy derived from a patient’s own blood and used in select musculoskeletal conditions. PRP is designed to deliver a concentrated source of platelets and growth factors to targeted tissues to support tissue healing and symptom improvement.

PRP injections are available following consultation with Dr. Sonam Maghera. Procedures are performed in a licensed medical facility in Ottawa. Treatment decisions are made on an individual basis after clinical assessment and imaging review.

What is Platelet-Rich Plasma (PRP)?

Platelet-rich plasma (PRP) is an autologous biologic treatment created by centrifuging a sample of the patient’s own blood to concentrate platelets above baseline levels.

Platelets contain bioactive growth factors and signaling proteins that play a role in tissue repair, inflammation modulation, and cellular communication. When injected into a targeted area, PRP is intended to support the body’s natural healing processes.

PRP may be used in joints, tendons, ligaments, or soft tissue structures depending on the clinical indication.

How does PRP work?

PRP works by delivering a concentrated source of your own platelets to a specific area of injury or degeneration.

After injection into the target tissue:

  • Platelets become activated and release growth factors and signaling proteins

  • These signals may help modulate local inflammation and support tissue repair

  • The goal is to create a biologic environment that encourages healing, rather than temporarily masking pain

Unlike cortisone, PRP does not act as a pain-numbing medication. Instead, it works by influencing the body’s natural healing processes.

Because of this mechanism, symptom improvement—when it occurs—is typically gradual and may develop over weeks to months, rather than immediately after the injection.

How long does PRP last?

For tendon-related conditions, PRP may help stimulate a healing response within the tendon, with the goal of supporting longer-term tissue improvement rather than short-term symptom relief alone. When effective, benefits may persist beyond the initial recovery phase, depending on tendon health, chronicity, and rehabilitation.

For joint conditions, including osteoarthritis, PRP is primarily used for symptom modulation. Clinical studies suggest that symptom improvement, when it occurs, may last approximately 6–12 months, and repeat injections may be considered thereafter.

PRP does not reverse arthritis or regenerate joint cartilage, and outcomes vary between individuals. As with all biologic treatments, response depends on the underlying pathology, disease severity, and patient-specific factors.

Who may be a candidate for PRP?

PRP may be considered for adults with select musculoskeletal conditions, including:

  • Tendinopathy (acute or chronic), such as Achilles, patellar, gluteal, rotator cuff, or elbow tendinopathy

  • Partial tendon tears, where surgery is not indicated

  • Ligament injuries, including partial tears or chronic ligament pain

  • Bursitis that has not responded to conservative treatment

  • Mild to moderate osteoarthritis, particularly of the knee or hip

  • Cartilage injury or chondropathy, including focal cartilage defects

  • Meniscal pathology, such as degenerative or stable meniscal tears

  • Muscle injuries, including partial muscle tears or chronic myofascial pain

  • Persistent joint or soft-tissue pain despite appropriate rehabilitation and conservative management

PRP is not appropriate for every condition or every patient, and outcomes vary depending on tissue type, chronicity, severity of pathology, and overall clinical context. A medical assessment is required to determine whether PRP is a suitable option.

How is the injection performed?

Arthrosamid® is administered as a single intra-articular knee injection, typically using image guidance to ensure accurate placement within the joint.

The procedure is performed under sterile conditions in a licensed medical facility. If a joint effusion is present, it may be aspirated prior to injection. The total injected volume is 6 mL, delivered during one treatment session.

PRP compared with other knee injections

  • Corticosteroid injections – short-term symptom relief, anti-inflammatory

  • Hyaluronic acid injections – temporary lubrication and shock absorption (used in joints

  • PRP – biologic treatment using autologous blood products

  • Arthrosamid® – non-biologic injectable implant designed for long-term symptom relief for joints

Treatment selection depends on diagnosis, goals, prior treatments, and clinical findings.

Safety and evidence

PRP is derived from the patient’s own blood, minimizing the risk of allergic reaction. Reported side effects are typically mild and may include temporary pain, swelling, or stiffness.

PRP has been studied across a range of musculoskeletal conditions, with variable results depending on indication and preparation method. Ongoing research continues to refine patient selection and treatment protocols.

Important note: Procedural options are discussed on an individual basis. Not all treatments are appropriate for every patient, and recommendations are based on clinical assessment, imaging findings, and available evidence.

Interested in learning more?

Patients interested in PRP injections require an in-person medical assessment to determine suitability. This allows for appropriate review of symptoms, imaging findings, medical history, and overall clinical context.
