A tendon or ligament injury can linger long after the initial swelling has faded. You may be able to manage your commute or finish a workout, only to feel the pain return as soon as you pick up the pace. PRP injections offer a minimally invasive way to support the body’s healing process in certain foot and ankle injuries. At Gotham Footcare, we use platelet-rich plasma therapy as part of a personalized treatment plan built around your diagnosis, biomechanics, and the activities you want to return to.
Platelet-rich plasma, or PRP, is prepared from a small sample of your own blood. The platelets are concentrated and injected into an injured or slow-healing area, where they may support tissue regeneration and repair. Because the preparation comes from your own blood, no donor tissue is required, and the likelihood of an allergic reaction is low.
PRP therapy is generally considered when a tendon, ligament, muscle, or plantar fascia injury has not improved enough with conservative care. It is not the first or only answer to chronic foot and ankle pain. Before recommending a platelet-rich plasma injection, the Gotham Footcare team evaluates why the tissue remains irritated and whether foot structure, gait, footwear, or training habits continue to place stress on it.
Blood consists of a liquid portion called plasma and three main formed components: red blood cells, white blood cells, and platelets. Red blood cells carry oxygen, while white blood cells support immune function. Platelets play an essential role in forming blood clots, but they also carry special proteins called growth factors that participate in the body’s natural healing process.
To create platelet-rich plasma, a blood sample is placed in a centrifuge machine. The centrifuge separates the platelets and plasma from the remaining blood components. This produces a plasma preparation with a high concentration of platelets compared with a normal blood specimen.
The exact concentration varies according to the preparation method. Some PRP preparations contain several times the platelet concentration found in normal blood, providing a higher concentration of the growth factors found in platelets. These growth factors may help recruit reparative cells and support collagen production, cellular signaling, and new tissue formation.
PRP injections are most often considered for soft tissue injuries that have not responded adequately to rest, supportive footwear, physical therapy, orthotics, or activity changes.
The plantar fascia is a strong band of tissue that supports the arch and absorbs stress with each step. Repetitive strain can cause persistent heel pain, often felt during the first few steps in the morning or after sitting for an extended period. PRP treatment may be considered when plantar fasciitis continues to cause painful symptoms despite appropriate conservative care.
The Achilles tendon connects the calf muscles to the heel. It plays an essential role in walking, running, climbing stairs, and pushing off the ground. Repetitive loading can lead to chronic degeneration, stiffness, thickening, or small areas of tendon damage. PRP therapy may support healing in selected cases of chronic Achilles tendinopathy. A complete rupture or substantial structural injury may require orthopedic surgery or another treatment approach.
The tendons of the foot and ankle absorb significant force during normal activities. Small injuries can accumulate when training increases too quickly, footwear provides inadequate support, or faulty mechanics repeatedly overload the same tissue. Depending on the tendon and extent of the damage, platelet-rich plasma PRP injections may be used as part of a broader treatment plan. Physical therapy, strengthening, footwear changes, and custom orthotics may still be needed to address the forces that contributed to the injury.
Certain ligament sprains, muscle injuries, and partial soft tissue tears can be slow to heal. PRP shots may be considered when the tissue remains structurally capable of healing but has not recovered as expected.
For an appropriate patient and diagnosis, potential benefits include:
PRP treatment does not provide the same outcome for every patient. Some people experience meaningful pain relief, while others notice limited improvement.
You may be a candidate if you have chronic plantar fascia, tendon, ligament, or muscle pain that has not improved enough with conservative treatment. PRP may also appeal to patients who want to explore a non-surgical option before considering a more invasive procedure.
PRP therapy may not be recommended for people with an active infection, certain blood conditions, significant anemia, or health problems that interfere with healing. A complete tendon rupture, unstable injury, or severe structural damage may require surgery instead.
A successful PRP treatment begins with an accurate diagnosis. Your Gotham Footcare provider will ask when your pain started, which movements trigger it, and how it affects your work, commute, or exercise. We will also review previous injuries, treatment attempts, footwear, activity habits, medications, and medical conditions.
Your examination may include strength testing, range-of-motion assessment, and a review of how you stand and walk. X-rays, ultrasound imaging, or MRI may be recommended when we need a clearer view of the bones, joints, tendons, ligaments, or adjacent nerves.
This evaluation determines whether PRP is appropriate and what additional treatment may be needed to keep the tissue from being repeatedly overloaded.
PRP injections are performed during an office visit and generally take approximately 30 to 60 minutes.
First, a small blood draw is performed, usually from your arm. The blood sample is placed in a centrifuge machine, which separates the platelet-containing plasma from the red blood cells and other components.
The treatment area is then cleaned using proper sterile technique. The prepared PRP is injected into the affected tissue. Ultrasound guidance may be used to identify the injured structure and place the injection accurately.
You may feel pressure or discomfort during treatment. Because PRP is injected into tissue that is already irritated, increased pain or soreness at the injection site can occur afterward.
Your provider will give you preparation instructions based on your health history and the area being treated. You should provide a complete list of medications and supplements, including anti-inflammatory medications, aspirin, and blood thinners. Never stop a prescribed medication without speaking with the clinician who manages it and your Gotham Footcare provider.
PRP injections are low-risk procedures overall, but the treated tissue needs time and protection. Limited downtime does not mean you should immediately return to running, heavy exercise, or a full day on your feet.
Temporary swelling, stiffness, bruising, or discomfort at the injection site is normal for a few days. Your provider will explain how much weight you can place on the foot and whether you need a supportive shoe, brace, or walking boot. Follow Gotham Footcare’s specific post-procedure care instructions regarding medication, activity, and the use of cold compresses or heat.
Daily movement is generally increased gradually. Physical therapy may begin or resume as the early soreness improves. Your return to running, dancing, or other high-impact activity will depend on the injury, symptoms, strength, and ability of the tissue to tolerate progressive loading.
PRP does not provide immediate pain relief. Some patients begin to notice improvement within several weeks, while tissue remodeling may continue for several months. More than one treatment may be recommended depending on the condition and response to the first injection.
The treatment is not universally effective. Follow-up appointments allow Gotham Footcare to evaluate your progress, modify rehabilitation, and determine whether additional treatment is appropriate.
PRP may encourage the body’s healing process, but it does not change foot structure, correct gait, or strengthen weak muscles on its own. A complete plan may also include physical therapy, progressive tendon loading, custom orthotics, supportive footwear, temporary bracing, or changes to training habits.
This combination supports the injured tissue while helping your foot and ankle manage the demands of daily movement more effectively.
Potential risks and temporary side effects include:
Injection-site infection or tissue damage is uncommon when treatment is performed using proper sterile technique, but no injection is completely risk-free. PRP uses your own blood, making an allergic reaction less likely than with many other injectables.
PRP is only one part of treating a chronic foot or ankle injury. Its value depends on the diagnosis, placement of the injection, and treatment plan surrounding it.
Gotham Footcare brings a foot-and-ankle-specific approach to regenerative medicine. Our team evaluates the injured tissue along with your gait, foot structure, footwear, work demands, and activity goals. When PRP is appropriate, we integrate it with imaging, rehabilitation, orthotics, and other treatments that address the full mechanical problem.
With convenient locations in Midtown and Downtown Manhattan, we understand that recovery has to work in the real world. Our goal is to help you return to comfortable movement with a plan that respects both the biology of healing and the pace of New York City.
Persistent heel, tendon, or ankle pain deserves a clear diagnosis. Schedule an appointment with Gotham Footcare to learn what is causing your symptoms and whether PRP injections should be part of your treatment plan.
Many patients can walk after treatment, but weight-bearing instructions depend on the tissue and injury. Some patients may temporarily need supportive footwear, a brace, or a walking boot.
Yes. Injection-site pain, swelling, and soreness are common temporary effects. PRP encourages a healing response that may initially increase inflammation in the treatment area.
Some patients receive one injection, while others may need multiple sessions. The recommendation depends on the diagnosis, severity of the injury, and response to treatment.
Many insurance companies consider PRP investigational, so treatment may not be covered. Patients should verify their individual benefits before proceeding.
No. Platelet-rich plasma PRP is prepared from concentrated platelets and plasma in your blood. It does not contain therapeutic stem cells.
Yes. Physical therapy can restore strength, mobility, and tissue tolerance while PRP supports the biological healing process. This combination may be particularly useful when weakness or poor biomechanics contributed to the injury.
