PRP Therapy Explained: How Platelet-Rich Plasma Heals Joints, Muscles & More
Platelet-rich plasma, also known as PRP, is a modern form of regenerative therapy that utilizes your body’s own healing abilities after an injury. To understand how PRP works, think about the last time you cut your finger. When this happens, the body’s defense cells release healing proteins to the cut area to initiate healing, initiating the healing process. These proteins initiate the process of new, healthy skin tissue formation at the injury site, and over time, they repair your cut by closing the wound with new skin. It’s quite amazing that your body does this on its own!
PRP is a tissue-healing blood product containing a high concentration of platelets and proteins prepared from your own blood to create new tissue in your muscles, ligaments, tendons, and even bones. Platelet-rich plasma has become one of the best methods for supporting the healing process of various tissues.
What is platelet-rich plasma?
Platelet-rich plasma consists of two elements: plasma, or the liquid portion of blood, and platelets, a type of blood cell that plays an important role in healing throughout the body. Platelets are well-known for their clotting abilities, but they also contain growth factors that can trigger cell reproduction and stimulate tissue regeneration or healing in the treated area. Platelet-rich plasma is simply blood that contains more platelets than normal.
To create platelet-rich plasma, clinicians take a blood sample from the patient and place it into a device called a centrifuge that rapidly spins the sample, separating out the other components of the blood from the platelets and concentrating them within the plasma.
In Which Diseases Is Platelet-rich Plasma Used?
In musculoskeletal disorders; it is used in diseases such as:
- ☑️ Osteoarthritis (knee, hip, shoulder, ankle);
- ☑️ Tendonitis and tendinopathy (Achilles, patellar, rotator cuff);
- ☑️ Tennis elbow (lateral epicondylitis);
- ☑️ Golfer’s elbow (medial epicondylitis);
- ☑️ Plantar fasciitis;
- ☑️ Ligament sprains and partial tears;
- ☑️ Muscle strains and chronic muscle injuries;
- ☑️ Sacroiliac (SI) joint dysfunction;
- ☑️ Degenerative disc disease;
- ☑️ Facet joint arthritis.
How is PRP Prepared and Applied?
In PRP treatment, clinicians collect blood from the patient and place it in special tubes, and place the tubes in a high-speed centrifuge. They rotate the centrifuge at a specific speed and duration to obtain platelet-rich plasma. The separation process takes approximately 15 minutes. Centrifugation separates the platelet- and growth factor-rich plasma from the blood.
The doctors inject the final mixture into the targeted area. They often use imaging methods such as ultrasound to identify the affected areas in tendon applications. They can administer the PRP at different intervals and frequencies. After the PRP course is completed, they can repeat the injections once or twice a year.
What is a PRP injection?
After creating platelet-rich plasma from a patient’s blood sample, doctors inject that solution into the target area, such as an injured knee or a tendon. In some cases, the clinician may use ultrasound to guide the injection. The idea is to increase the concentration of specific bioproteins or hormones, called growth factors, in a specific area to accelerate the healing process.
The mechanism behind PRP injections is not completely understood. Studies show that the increased concentration of growth factors in platelet-rich plasma may stimulate or speed up the healing process, shortening healing time for injuries, decreasing pain and even encouraging hair growth.
What are the benefits of Platelet-rich Plasma?
Platelet-rich plasma fluid contains high amounts of blood cells called platelets. These cells contain a number of growth factors that help strengthen cartilage, tendons, ligaments, and bones, and promote tissue healing. The benefits of platelet-rich plasma include:
- ☑️ Stimulates natural healing by releasing growth factors;
- ☑️ Reduces inflammation in injured or affected tissues;
- ☑️ Accelerates recovery of muscles, tendons, and ligaments;
- ☑️ Improves joint function and mobility;
- ☑️ Enhances regeneration of cartilage and connective tissues;
- ☑️ Minimally invasive and uses the patient’s own blood;
- ☑️ Low risk of allergic reaction or rejection;
- ☑️ Reduces the need for surgery or long-term medication.

In which diseases is PRP effective?
PRP has been applied in various areas of general surgery, plastic surgery, and orthopedics. Commonly used areas in orthopedics include:
🦴 1. Chronic Tendinopathies
PRP is effective in the treatment of chronic tendon injuries, especially tennis elbow, which is a very common injury to the tendons in the elbow. The use of PRP is also promising in diseases such as chronic Achilles tendonitis, inflammation of the patellar tendon in the knee, and plantar fasciitis.
🦵 2. Knee Osteoarthritis
Patients with early-stage osteoarthritis of the knee joint have reported pain reduction and improved function with PRP injections. However, it’s important to remember that PRP treatment does not alter the natural course of the disease and cannot reverse existing wear and tear.
💪 3. Muscle and Ligament Injuries
PRP is also widely used for sports injuries such as ligament and muscle injuries. It can be used to treat athletes with knee sprains and muscle strains, which are common sports injuries.
🧬 4. Cartilage Damage
Cartilage is a slow-healing part of the body. This is because cartilage lacks adequate blood supply and doesn’t receive any growth factors. As a result, the healing process is often slow and unsatisfactory. PRP can help improve cartilage by increasing blood flow, allowing more growth factors to reach the cartilage in need of repair.
🧑🦲 5. Hair Loss
PRP injections can be effective in treating male pattern baldness, both in preventing hair loss and promoting new hair growth. Platelet-rich plasma can also aid in the stimulation of hair growth after hair transplants.
💆♀️ 6. Skin Rejuvenation
Doctors sometimes use PRP injections as an anti-aging treatment, but there is little evidence to show that PRP reduces wrinkles and other signs of aging.
PRP Therapy Risks and Side Effects
A PRP injection is a low-risk procedure and does not usually cause major side effects. The procedure involves a blood draw, so you should make sure you are hydrated and have eaten beforehand to prevent feeling lightheaded. After the procedure, you may experience some soreness and bruising at the injection site.
Because PRP injections are made up of your own cells and plasma, the risk of an allergic reaction is much lower than with other injectable medications like corticosteroids. Less common risks of PRP injections include:
- ⚠️ Infection at the injection site;
- ⚠️ Nerve or tissue damage;
- ⚠️ Increased pain or inflammation temporarily after injection;
- ⚠️ Mild bleeding or bruising at the injection area;
- ⚠️ No improvement in symptoms (in rare cases).
If you are considering PRP injections, be sure to talk with your health care provider about all the benefits and risks.
In which cases and to whom should PRP treatment not be applied?
PRP (Platelet-Rich Plasma) therapy is generally safe, but it may not be suitable for everyone. It should be avoided in individuals with certain health conditions or risk factors.
- ❌ People with blood or platelet disorders;
- ❌ Patients with active infections or sepsis;
- ❌ Individuals undergoing chemotherapy or radiation therapy;
- ❌ People with severe anemia or low platelet count;
- ❌ Those taking anticoagulant (blood-thinning) medications;
- ❌ Patients with uncontrolled diabetes or autoimmune diseases;
- ❌ Pregnant or breastfeeding women (as a precaution).
When Should PRP Injections Begin?
If the patient is an athlete, it is appropriate to perform the procedure one week following the sports injury. In the chronic phase, it can be performed at any time if the patient has not responded to other treatments, such as physical therapy, medication for 3-6 months.
When Should You Start Exercises After PRP?
After PRP, you can start a range of motion exercises after two days of rest. You should resume light aerobic exercise such as walking and swimming within 3-7 days. You can also incorporate eccentric strengthening exercises into the program within 2-3 weeks. You can also initiate athletic exercises approximately 3-4 weeks later. You may administer additional injections if necessary during a follow-up examination following the 4-6 week exercise program.
What should you do after PRP is applied?
After the procedure, you may experience mild pain and swelling in the treated area, which is temporary and usually subsides within 2-3 days. In such cases, you can use acetaminophen-type painkillers as recommended by your doctor. However, some painkillers are known to counteract the positive effects of PRP, so it’s important not to use any painkillers unless directed by your doctor.
You can return to your daily routine immediately after the procedure, but it’s recommended to avoid excessive strain and intense physical activity for the first three days. Rest is an important part of recovery, but simply, you cannot perform non-weightbearing exercises and stretching.
