Can PRP Therapy Help Me Avoid Knee Surgery?

Yes, PRP therapy may delay or even help you avoid knee surgery if your knee still has enough healthy tissue. It supports your body’s natural healing process, helps relieve symptoms, and may improve joint function. However, the results depend on your underlying condition and the extent of joint damage.

At Total Orthopedics & Sports Medicine, our knee specialist, Dr. Michael Shindle, approaches every knee condition with a long-term treatment strategy. Rather than focusing only on short-term symptom relief, he considers whether PRP can support your activity level and postpone surgery while preserving future treatment options if your condition worsens. By identifying the right treatment at the right stage, he helps you avoid unnecessary delays. Call 855-321-6784 to book your appointment.

Is PRP Therapy an Alternative to Knee Surgery?

Yes, PRP injections can be an alternative to knee surgery for some patients, but they are not a replacement for surgery in every case. They are commonly used for conditions that may still improve without surgery, including early knee arthritis and mild cartilage damage. However, advanced joint damage or significant structural problems may still require surgical intervention.

A 2025 meta-analysis of 15 randomized controlled trials involving 1,632 patients found that PRP provided greater pain relief and functional improvement at 12 months. Another 2025 meta-analysis reported that PRP was significantly more effective than placebo for improving pain and function in knee osteoarthritis. Similarly, a separate 2025 systematic review concluded that PRP offers clinically meaningful benefits, especially when prepared with an optimal platelet concentration.

While these studies show favorable results, success is not defined by pain relief alone. Treatment should also help you move more comfortably, complete everyday activities more easily, and return to the lifestyle you enjoy. Those improvements may help postpone surgery while maintaining your quality of life.

How Do Doctors Decide if PRP Is Right for You?

Our sports medicine specialist, Dr. Michael Shindle, identifies the exact source of your knee pain before recommending PRP treatment. He evaluates how closely your symptoms match the findings on your examination and imaging before deciding whether PRP is the right treatment for your specific condition.

In some cases, your symptoms and imaging may not clearly identify the primary source of pain. A diagnostic injection can help determine whether the discomfort is coming from inside the knee joint or from surrounding structures. This additional information helps guide treatment recommendations and improves the accuracy of the diagnosis.

In addition, even when two patients have the same diagnosis, they may not receive the same treatment recommendation. Therefore, before recommending PRP, our doctor carefully evaluates the following factors:

• The severity of joint or cartilage damage
• Your age and activity level
• The location and type of the knee injury
• Your response to previous non-surgical treatments
• Your overall health and healing potential
• How long have your symptoms been present

During your consultation, Dr. Michael Shindle also explains the expected benefits of PRP, its limitations, and the factors that may affect your recovery. Moreover, he explains where PRP fits within your overall treatment strategy and how it works alongside other treatments. This ensures you understand the full treatment process before deciding to proceed. His goal is to ensure you choose a treatment based on clear expectations rather than assumptions. If you’re unsure whether PRP is the right treatment for your knee, schedule a consultation with Dr. Michael Shindle.

Which Knee Conditions Respond Best to Regenerative Therapy?

PRP is commonly recommended for early to moderate knee osteoarthritis, certain tendon injuries, degenerative meniscus tears, and mild cartilage damage. However, treatment success also depends on the severity of the condition and careful patient selection. Here’s how these common knee conditions may respond to PRP treatment:

• Early to Moderate Knee Osteoarthritis: PRP may help reduce inflammation, improve knee function, and relieve pain before osteoarthritis progresses to more advanced joint damage.
• Degenerative Meniscus Tears: Patients with degenerative meniscus tears from gradual age-related wear may experience symptom relief without immediate surgical treatment.
• Chronic Tendon Injuries: PRP may support the natural healing response in chronically irritated tendons, which often have a limited blood supply and heal more slowly.
• Mild Cartilage Damage: When cartilage damage is still mild, regenerative therapy may help improve the joint environment and manage symptoms before the condition progresses.
• Patellar Tendinopathy (Jumper’s Knee): PRP may help reduce persistent tendon pain and improve function when symptoms continue despite appropriate rehabilitation.

Can PRP Delay Knee Replacement Surgery?

Yes, PRP may delay knee replacement for patients whose symptoms can still be managed without surgery. Reducing pain and improving joint function may help extend the effectiveness of conservative care. In a large retrospective study involving 667 patients, 74.1% delayed total knee replacement by more than 1.5 years, with a median delay of 5.3 years. In the same study, 85.7% of patients who received PRP had not undergone knee replacement at five-year follow-up.

However, delaying a knee replacement does not necessarily mean avoiding surgery permanently. Instead, it means there is still an opportunity to manage your symptoms effectively without proceeding to surgery. But the time PRP may delay knee replacement surgery varies among patients.

It depends on factors such as the severity of osteoarthritis, the rate at which the condition progresses, your activity level, overall health, and your individual response to treatment. Regular follow-ups help determine whether PRP is still controlling your symptoms or whether a different treatment approach should be considered.

How Does PRP Compare With Other Knee Treatments?

Unlike medications or corticosteroid injections that primarily relieve symptoms, PRP stimulates the body’s natural repair mechanisms using your own platelets. Because it targets the underlying healing response rather than simply masking pain, symptom relief may continue to improve over the weeks after treatment.

However, PRP is not usually the first treatment recommended for every patient with knee pain. Many people improve with activity modification, weight management, or short-term medication. PRP is generally considered when symptoms continue despite these measures or when the condition has not progressed to the stage where surgery is the preferred option.

Here are some clinical studies comparing PRP with other commonly used knee treatments:

• A 2024 network meta-analysis of 48 studies found that PRP injections can reduce inflammation and improve mobility better than cortisone or hyaluronic acid.
• A systematic review of randomized controlled trials concluded that PRP yielded better pain relief and functional outcomes than hyaluronic acid injections, particularly at longer follow-up periods.
• According to PubMed, PRP provided greater improvements in joint pain and function than corticosteroid injections at mid- and long-term follow-up.
• A 2025 meta-analysis of 11 randomized controlled trials found that PRP significantly improved pain and knee function compared with placebo in patients with knee osteoarthritis.

When Do Orthopedic Surgeons Recommend Surgery?

Surgery is generally recommended when non-surgical knee treatments no longer provide enough relief, and your knee condition continues to interfere with everyday activities. Before recommending a surgery, your orthopedic surgeon confirms that the source of your symptoms can be corrected surgically. They recommend surgery only when it is expected to provide a better outcome than continued conservative treatment.

Depending on your diagnosis, your orthopedic surgeon may recommend surgery for the following conditions:

• Advanced Knee Osteoarthritis: Severe cartilage loss causing persistent pain, stiffness, and reduced mobility despite appropriate non-surgical treatment.
• Complex or Displaced Meniscus Tears: Tears that do not heal on their own or continue to cause locking, catching, or instability.
• Complete ACL or PCL Tears: Ligament injuries that result in significant knee instability, particularly in active individuals.
• Symptomatic Cartilage Defects: Large areas of cartilage damage that continue to cause pain and mechanical symptoms despite conservative care.
• Unstable Osteochondral Lesions: Damage involving both cartilage and underlying bone that may require surgical repair or restoration.
• Loose Bodies Within the Knee Joint: Fragments of cartilage or bone that cause locking, catching, or restricted movement.
• Patellar Instability: Recurrent kneecap dislocations or persistent instability that does not improve with rehabilitation.
• Severe Tendon Ruptures: Complete quadriceps or patellar tendon tears that impair the ability to straighten the knee.
• Fractures Around the Knee Joint: Broken bones affecting the joint surface or stability that require surgical fixation.
• Advanced Knee Arthritis Requiring Joint Replacement: Extensive cartilage loss causing persistent pain, stiffness, and reduced mobility despite appropriate non-surgical treatment.

Why Doesn’t PRP Work for Everyone?

Not every patient responds to PRP in the same way because the body’s healing response varies from one person to another. Factors such as platelet quality, tissue health, blood supply, and the severity of the injury can all affect the response to treatment. As a result, patients with the same diagnosis may experience different clinical outcomes after PRP therapy.

How Do You Know if Knee Damage Is Getting Worse?

A gradual increase in pain, stiffness, and functional limitations is often a sign that knee damage is worsening. You may also notice increasing stiffness, reduced range of motion, or difficulty walking, climbing stairs, or standing for extended periods. In addition, the following symptoms may also need prompt medical evaluation:

• Sudden Knee Locking: The knee becomes stuck and cannot fully bend or straighten.
• Repeated Giving Way: The knee unexpectedly buckles or feels unstable during walking.
• Persistent Swelling: Swelling that does not improve with rest or continues to recur.
• Noticeable Joint Deformity: A change in the shape or alignment of the knee.
• Inability to Bear Weight: Difficulty or inability to stand or walk on the affected leg.
• Pain at Rest or During the Night: Pain that continues even when you are not active.
• Redness and Warmth Around the Joint: These changes may indicate an infection or significant inflammation and require prompt evaluation.
• Fever with Knee Pain and Swelling: A combination of fever and joint symptoms requires urgent medical assessment to rule out infection.

One pattern we commonly see is that patients often adapt to worsening knee damage without realizing it. Instead of recognizing new symptoms, they gradually change how they move by avoiding stairs, taking shorter walks, or relying more on the opposite leg. These gradual adjustments can mask worsening knee damage, making it difficult to notice that the condition is getting worse.

Therefore, if you notice new limitations developing over time, do not assume they are simply part of getting older. Schedule an appointment with Dr. Michael Shindle for a thorough evaluation. Early diagnosis helps determine whether your symptoms represent ongoing recovery or worsening knee damage.

How Is PRP Therapy Actually Performed?

During PRP therapy, doctors collect a small blood sample, prepare a concentrated platelet solution, and inject it into the affected area of your knee. It is a minimally invasive procedure performed during the same appointment. You can usually return home shortly after the procedure. Here’s the step-by-step process doctors follow to perform PRP therapy safely:

Blood Sample Collection

Your doctor begins by drawing a small sample of blood from a vein in your arm. The process is similar to a routine blood test and usually takes only a few minutes. Because PRP is prepared from your own blood, the risk of rejection or an allergic reaction is minimal. The blood is collected in a sterile tube and prepared for processing. However, the volume of blood collected depends on the PRP preparation system your doctor uses.

Platelet Separation and Concentration

The blood sample is then placed in a centrifuge, where it spins at high speed to separate the different blood components. Your doctor isolates the platelet-rich layer from the remaining blood cells. Once isolated, the platelet-rich layer is transferred into a sterile syringe for injection. This high-concentration platelet layer contains growth factors that help support the body’s natural healing process.

Injection Site Preparation

Before the injection, your doctor cleans the skin around your knee. They identify the precise area that needs treatment using your examination findings and imaging. In most cases, they also use ultrasound guidance. This helps them place the injection more accurately. Additionally, precise injection placement ensures the PRP reaches the targeted tissue rather than the surrounding healthy structures.

PRP Injection

After identifying the treatment area, your doctor inserts a sterile needle into the affected tissue. Then, the prepared PRP is injected directly into the target area with careful precision. Mild pressure or temporary soreness is common during this step. The injection is typically completed within a few minutes. Because the procedure is minimally invasive, no stitches are needed.

Immediate Aftercare

After the injection, your doctor places a small bandage over the injection site. You will usually rest for a few minutes before leaving the clinic. Although you can return home the same day, mild soreness, swelling, or stiffness during the first few days is common. Before you leave, your doctor will also explain your activity restrictions and aftercare instructions. Following these guidelines helps protect the treated area and supports the early healing process.

What Should You Avoid After Treatment?

Avoid high-impact activities, anti-inflammatory medications, and excessive strain on your treated knee after PRP therapy to support the healing process. Instead, follow your doctor’s activity restrictions during the first few days to give the treated tissue time to recover. As your knee heals, gradually resume your normal activities only as recommended by your doctor.

Here are some additional precautions your doctor may recommend after PRP therapy:

• Smoking: Avoid smoking because it can reduce blood flow and interfere with the body’s natural healing response.
• Alcohol Consumption: Limit alcohol intake during the early recovery period, as excessive alcohol may impair tissue healing.
• Heat: Avoid hot tubs, saunas, heating pads, and prolonged hot showers over the treated knee for the first 48 hours unless your doctor advises.
• Massage Over the Injection Site: Do not massage or apply deep pressure directly over the treated area during the early healing phase.
• Monitoring New Symptoms: Contact your doctor promptly if you develop worsening redness, warmth, fever, severe swelling, or worsening pain, rather than assuming these symptoms are part of normal recovery.

How Soon Can You Expect Knee Pain Relief?

Most patients begin to notice relief from knee pain within two to six weeks after PRP therapy, although the exact timeline varies depending on your condition and your body’s healing response. Because PRP works by stimulating tissue repair rather than providing immediate pain relief, improvement is usually gradual. Many patients continue to experience additional improvement over the following weeks.

A 2022 randomized controlled trial published in Cureus found that patients treated with PRP showed measurable improvements at six weeks, with continued progress at three months and six months after treatment. Another 2025 meta-analysis of 15 randomized controlled trials involving 1,632 patients found that patients continued to experience improvement throughout the 12-month follow-up period.

Can Lifestyle Changes Improve Treatment Results?

Yes, healthy lifestyle changes can improve the results of PRP therapy by supporting your body’s natural healing process. For example, maintaining a healthy weight, following your rehabilitation plan, and eating a balanced diet can support your body’s healing process. Besides that, staying physically active within your doctor’s recommendations helps improve knee function while protecting the treated joint during recovery.

What Are the Risks and Side Effects of PRP?

PRP therapy carries a low risk of complications because it uses your own blood, but mild side effects can occur after the injection. For example, you may experience temporary soreness, swelling, stiffness, or bruising around the injection site for a few days. Serious side effects, such as nerve injury or infection, are also possible but uncommon with PRP injections.

The following health conditions and lifestyle factors may increase the risk of PRP side effects or delay recovery:

• Diabetes: May slow the body’s natural healing response and prolong recovery.
• Smoking: Reduces blood flow and can interfere with tissue healing after the injection.
• Blood Thinners: May increase the risk of bruising or bleeding at the injection site. But never stop these medications unless your prescribing physician instructs you.
• Active Infection: Doctors generally postpone PRP injections until the infection has completely resolved.
• Immune Disorders: Certain immune system conditions or medications that suppress the immune system may affect the body’s healing response.
• Poor Overall Health: Chronic medical conditions or poor general health may affect how your body responds to PRP therapy and its recovery process.

How Much Does PRP Cost and Is It Covered by Insurance?

PRP injection costs range from $500 to $2,000 per injection, depending on your condition and the treatment protocol. In some cases, PRP injections can be more cost-effective than surgery, particularly for patients with higher surgical risks.

However, most commercial insurance plans and Medicare do not cover PRP for orthopedic conditions because many insurers still classify it as an investigational treatment. Our medical team can verify your insurance coverage and explain any available benefits. For patients without coverage, we provide clear self-pay pricing along with flexible payment options.
