PRP and Regenerative Medicine for Foot and Ankle Injuries

Tendon pain that lingers for months, a ligament that never quite feels right after a sprain, or heel pain that does not respond to stretching and orthotics can be frustrating. For some of these conditions, regenerative medicine offers non-surgical options designed to support the body's natural healing process. Platelet-rich plasma, better known as PRP, is the most widely recognized of these treatments. This guide explains how regenerative therapies work, which foot and ankle conditions they are used for, and what to expect if you are considering them.

What is regenerative medicine?

Regenerative medicine refers to treatments that aim to stimulate or support the repair of damaged tissue rather than simply masking symptoms. In foot and ankle care, these treatments are often called orthobiologics because they use biological materials, frequently derived from the patient's own body, to help tendons, ligaments, cartilage and other soft tissues heal. They are typically considered for chronic or slow-healing problems, often after standard conservative treatment has been tried.

How PRP works

Platelets are blood cells best known for helping blood clot, but they also contain proteins called growth factors that play a role in tissue repair. To prepare PRP:

1. A small amount of blood is drawn from your arm, similar to a routine blood test.
2. The blood is placed in a centrifuge, which spins it to separate the platelets from other components.
3. The concentrated platelet-rich plasma is collected and injected into the injured area, sometimes using ultrasound guidance for accuracy.

Because PRP comes from your own blood, the risk of allergic reaction is low. The goal is to deliver a high concentration of healing factors directly where they are needed, stimulating and supporting repair in chronic injuries.

Foot and ankle conditions treated with PRP

PRP and related therapies may be considered for:

• Plantar fasciitis: especially long-standing heel pain that has not improved with conservative care. See our plantar fasciitis guide.
• Achilles tendinopathy: chronic pain and thickening of the Achilles tendon.
• Other tendon problems: such as posterior tibial or peroneal tendinitis.
• Ligament injuries: including slow-healing ankle sprains and chronic instability. Read about ankle sprain recovery.
• Arthritis: to help manage pain and function in arthritic joints.
• Surgical healing: in some cases, as part of surgery to support tissue repair.

Research on PRP continues, and results vary depending on the condition, the preparation and the individual patient. A good candidate is usually someone with a clear diagnosis whose symptoms have persisted despite a reasonable course of standard treatment.

Other regenerative options

Foot & Ankle Specialists of South Jersey offers several orthobiologic therapies through its Regenerative Health & Wellness Center, described in detail on our regenerative therapies page:

• MLS laser therapy: a non-invasive, multi-wave robotic laser used to reduce pain and inflammation and to promote soft tissue repair. It does not involve injections.
• Bone marrow aspirate therapy (BMAC): uses cells collected from a patient's own bone marrow, injected into damaged areas to stimulate healing. It is commonly used for arthritis in larger joints as well as the ankle.
• Wharton's Jelly umbilical product: a connective tissue from the umbilical cord that provides growth factors and proteins involved in healing.
• Adipose-derived cell therapy: uses cells derived from the patient's own fat tissue, processed and injected into the area of injury or pain.

Our practice's experience with regenerative medicine is long-standing: Dr. Frank J. Tursi has nearly 20 years of experience in the field and developed protocols for using PRP, amniotic membrane and umbilical cord product injections to treat common foot and ankle injuries non-surgically.

What to expect during a PRP treatment

PRP is performed in the office and usually takes about an hour, including blood draw, preparation and injection. The area may be numbed for comfort. Afterward, it is common to feel soreness for a few days as the healing response begins. Your provider may recommend a protective boot or modified activity for a period, and may ask you to avoid anti-inflammatory medications that could interfere with the healing process.

Recovery and results

Regenerative treatments work gradually. Rather than providing immediate relief, they aim to support tissue repair over the following weeks and months. Some patients need more than one treatment. Results are best when regenerative therapy is combined with the right supporting care, such as stretching and strengthening exercises, supportive footwear and custom orthotics, so that the forces that caused the injury are also addressed.

PRP compared with cortisone injections

Cortisone (corticosteroid) injections and PRP are sometimes discussed together, but they work differently. Cortisone is a powerful anti-inflammatory medication that can provide relatively fast pain relief, which is helpful for some conditions. However, repeated steroid injections into or near tendons are generally used cautiously. PRP, by contrast, is intended to support the healing process itself, so relief usually builds more gradually. Your podiatrist will explain which approach, or which combination of treatments, makes the most sense for your diagnosis.

Realistic expectations

Regenerative medicine is an evolving field. It is not a cure-all, and no treatment can guarantee a specific result. Honest conversations about the evidence for your condition, the likely timeline and alternative options are part of a good consultation.

Is regenerative medicine right for you?

These treatments are not a first step for every injury, and they are not appropriate for everyone. Factors your podiatrist will consider include your diagnosis, how long you have had symptoms, what treatments you have already tried, your overall health and your activity goals. Some regenerative therapies may not be covered by insurance, so it is worth discussing cost and coverage during your consultation.

Questions to ask your provider

• What is my exact diagnosis, and why is a regenerative treatment being recommended?
• What results can I realistically expect, and over what time frame?
• How many treatments might I need?
• What activity restrictions will I have afterward?
• What other treatment options do I have?
• Is the treatment covered by my insurance plan?

If chronic foot or ankle pain has not improved with standard care, a consultation can help determine whether PRP or another regenerative therapy could be part of your plan. Contact any of our South Jersey offices to schedule an evaluation.
