PRP Therapy for Musculoskeletal Pain & Injuries

PRP stands for platelet-rich plasma. It is prepared from a small sample of your own blood, which is processed to separate and concentrate platelets and plasma. That concentrate is then injected into the targeted area.

Platelets contain a variety of growth factors and signaling molecules involved in the body's natural response to tissue injury. The goal of PRP is not simply to numb pain — it is intended to modify the local biological environment and potentially support the body's healing response.

PRP is an orthobiologic treatment, not a guaranteed regenerative one. Although laboratory and clinical research suggests PRP can influence inflammation and tissue biology, the extent to which it actually regenerates damaged cartilage, tendon, or ligament in humans remains an active area of research.

One of the most extensively studied applications of PRP is knee osteoarthritis. Studies suggest PRP may reduce pain and improve function in some patients with symptomatic knee osteoarthritis. The American Academy of Orthopaedic Surgeons has described the evidence as limited but supportive of potential pain and functional improvement, while emphasizing variability among studies and PRP preparations.

More recent guidance from the American Academy of Physical Medicine and Rehabilitation also recognizes PRP as a reasonable option for selected patients with knee osteoarthritis, while emphasizing individualized treatment and the need for additional high-quality research.

PRP may be particularly worth considering for patients who:

• ✦Have symptomatic mild-to-moderate knee osteoarthritis
• ✦Continue to experience pain despite conservative treatment
• ✦Want to explore non-surgical treatment options
• ✦Have not obtained adequate relief from other injections
• ✦Want to remain active and delay or avoid surgery when medically appropriate

PRP is not a replacement for knee replacement surgery when advanced osteoarthritis has progressed to the point that surgery is otherwise indicated.

PRP has also been studied extensively for chronic tendinopathies. Tendons often have relatively limited blood supply and may develop persistent pain and structural changes after repetitive stress or injury.

The evidence varies by tendon and condition — some tendinopathies have shown encouraging outcomes, while other studies have shown mixed or limited benefit. For this reason, accurate diagnosis is particularly important before proceeding with PRP.

PRP treatment typically begins with a small blood draw. The blood is processed using a specialized centrifugation system to separate and concentrate the platelet-rich portion.

Your physician then identifies the treatment area and injects the PRP into the targeted joint, tendon, ligament, or soft tissue. Depending on the anatomy, ultrasound guidance may be used to improve accuracy and allow visualization of the relevant structures.

The procedure commonly takes approximately 30 to 60 minutes, although the total appointment may be longer. Because PRP uses your own blood, there is no concern about an allergic reaction to the injected platelets themselves.

Some discomfort during and after the injection is possible. PRP injections can produce temporary soreness, aching, or increased pain at the treatment site — this is not necessarily a sign that something has gone wrong, and the tissue may remain sore for several days.

You may experience temporary soreness, mild swelling, aching, or increased sensitivity at the injection site. Many patients return home the same day.

Your physician may recommend a period of relative rest followed by a gradual return to activity and a structured rehabilitation program. For tendon and ligament conditions in particular, physical therapy and progressive loading are often an important part of the plan.

PRP is not intended to replace rehabilitation.

PRP is different from an anesthetic or steroid injection — it is not necessarily expected to provide immediate pain relief. Some patients notice improvement within several weeks, while others require longer to determine the full response.

The time course depends on the condition treated, the severity of the injury or arthritis, the tissue involved, the PRP preparation, individual healing characteristics, and rehabilitation following treatment.

We evaluate your response over time rather than judging success solely on the first few days after injection.

The duration of benefit varies significantly. Some patients experience improvement for several months or longer, while others experience limited or no benefit. For knee osteoarthritis, studies have reported improvements extending beyond the immediate post-injection period, but results are inconsistent across studies and preparations.

There is also no universal PRP treatment schedule. Some conditions may be treated with a single injection, while other protocols use a series. Research in knee osteoarthritis has evaluated both single- and multiple-injection protocols with inconsistent results, and current evidence does not establish one universally superior schedule.

We do not promise a specific duration of pain relief. Your physician will recommend a plan based on your individual condition rather than a one-size-fits-all protocol.

Because PRP is prepared from your own blood, it is generally well tolerated. The most common issues relate to the injection itself and may include:

• ✦Temporary pain
• ✦Soreness
• ✦Swelling
• ✦Bruising
• ✦Stiffness
• ✦Temporary worsening of symptoms

As with any injection, there is a small risk of infection, bleeding, nerve or blood-vessel injury, or other procedure-related complications.

Additional evaluation or precautions may be necessary in patients with:

• ✦Active infection
• ✦Significant blood disorders
• ✦Certain platelet disorders
• ✦Severe anemia
• ✦Certain bleeding disorders
• ✦Certain cancers or systemic illnesses
• ✦Inability to temporarily modify medications when medically necessary
• ✦Advanced joint degeneration where surgery may be more appropriate

Do not stop any prescribed medication on your own. Some medications, including certain anti-inflammatories and blood thinners, may affect the plan — your physician will provide individualized instructions before treatment.

An important consideration is that PRP is not a single standardized product. Different systems produce preparations with different platelet concentrations, leukocyte concentrations, red blood cell content, and plasma volumes.

Research suggests the characteristics of the preparation may influence outcomes, and there is currently no single preparation established as optimal for every musculoskeletal condition. At NuvMed, the approach is selected based on the condition being treated and the patient's individual needs.

PRP is different from corticosteroid injections and other injectable treatments. Corticosteroids primarily reduce inflammation and may provide relatively rapid symptom relief, while PRP is intended to influence the local biological environment and may have a slower onset of benefit.

Hyaluronic acid, corticosteroids, PRP, and other injections each have different potential benefits and limitations. The best treatment depends on your diagnosis, severity of disease, previous treatments, goals, and individual risk factors.
