Chronic tendon injuries can cause persistent pain, stiffness, weakness, and reduced mobility that interfere with work, exercise, and everyday activities. While many tendon problems improve with rest, physical therapy, and activity modification, some continue for months despite conservative treatment.
For selected patients, PRP therapy for chronic tendon injuries may be considered as part of a regenerative medicine treatment plan designed to support the body’s natural healing response.
Platelet-Rich Plasma (PRP) therapy uses a concentrated preparation derived from the patient’s own blood. Because platelets contain growth factors and other biologically active proteins involved in tissue repair, PRP may be used for certain chronic tendon and musculoskeletal conditions.
The goal is not simply to temporarily mask pain, but to support healing in damaged tissue when clinically appropriate.
What is a chronic tendon injury?
Tendons are strong bands of connective tissue that attach muscles to bones. They transfer force from the muscles and play an essential role in movement, stability, and joint function.
A tendon can become injured suddenly, but many tendon problems develop gradually from repetitive stress. When symptoms continue over an extended period, the condition may involve chronic tendon degeneration, sometimes referred to as tendinopathy.
Common chronic tendon conditions include:
- Rotator cuff tendinopathy affecting the shoulder.
- Tennis elbow or lateral epicondylitis.
- Golfer’s elbow or medial epicondylitis.
- Patellar tendinopathy affecting the knee.
- Achilles tendinopathy affecting the back of the ankle.
- Other repetitive-use tendon injuries involving the joints and extremities.
What causes chronic tendon pain?
Tendon injuries are often associated with repetitive loading or overuse. Athletes may develop symptoms from repeated training, but tendon problems can also affect people whose occupations or everyday activities involve repetitive movements.
Common contributing factors include:
- Repetitive physical activity that repeatedly loads the same tendon.
- Sudden increases in exercise or activity intensity.
- Improper movement mechanics placing excessive stress on a tendon.
- Previous injuries that have not fully recovered.
- Age-related changes in tendon structure and healing capacity.
- Occupational activities involving repetitive lifting, reaching, gripping, or movement.
Unlike an acute injury, chronic tendinopathy may involve gradual changes in tendon structure rather than a single episode of inflammation.
What are the symptoms of a chronic tendon injury?
Symptoms vary depending on the tendon involved, but patients commonly experience:
- Persistent pain around the affected tendon or joint.
- Pain that increases during physical activity.
- Stiffness, particularly after periods of inactivity.
- Tenderness when touching the affected area.
- Reduced strength or difficulty performing certain movements.
- Pain that improves temporarily with rest but returns when activity resumes.
When these symptoms continue despite conservative treatment, further medical evaluation may be appropriate.
What is PRP therapy?
Platelet-Rich Plasma therapy is a regenerative medicine procedure that uses components of the patient’s own blood. A small blood sample is collected and processed to create a preparation containing a higher concentration of platelets.
The PRP preparation is then injected into the targeted area based on the patient’s diagnosis and treatment plan.
Platelets are best known for their role in blood clotting, but they also contain growth factors and signaling proteins involved in the body’s natural tissue repair processes. PRP therapy aims to concentrate these components at the site of an injury.
How may PRP support tendon healing?
Chronic tendon injuries can be challenging because tendons generally have a more limited blood supply than many other tissues. This can contribute to slower healing and persistent symptoms.
PRP is intended to deliver a concentrated source of platelets and associated growth factors directly to the injured area. These biological components participate in processes related to tissue repair and healing.
For appropriate patients, PRP may be considered with the goals of:
- Supporting the body’s natural healing response.
- Promoting biological activity within damaged tendon tissue.
- Reducing persistent pain as the condition improves.
- Supporting improved movement and function.
- Providing a treatment option when conservative approaches have not produced adequate improvement.
Results vary between patients, and PRP is not appropriate for every type of tendon injury.
What tendon injuries may be treated with PRP?
PRP may be considered for selected chronic tendon and musculoskeletal conditions after a detailed medical evaluation.
Depending on the patient’s diagnosis, these may include:
- Chronic rotator cuff tendon injuries
- Elbow tendinopathy, including tennis elbow and golfer’s elbow
- Patellar tendon injuries
- Achilles tendon problems
- Other chronic tendon conditions that have not responded adequately to conservative treatment
The decision to use PRP should be based on the specific diagnosis, severity and duration of symptoms, previous treatment, and the patient’s overall medical condition.
When should PRP be considered for chronic tendon pain?
PRP is generally not the first treatment considered for every tendon problem. Many patients initially receive conservative care aimed at reducing symptoms and restoring normal function.
This may include:
- Activity modification
- Physical therapy and therapeutic exercise
- Appropriate medication management
- Changes in movement mechanics or ergonomics
- Gradual return to physical activity
If tendon pain remains persistent despite appropriate conservative treatment, regenerative medicine options such as PRP may be discussed following further evaluation.
How is a tendon injury evaluated before PRP?
A proper diagnosis is essential before performing any regenerative medicine procedure. Pain around a joint does not necessarily mean the tendon is the source of the problem.
Evaluation may include:
- A detailed review of symptoms and medical history.
- Physical and musculoskeletal examination.
- Assessment of strength and range of motion.
- Review of previous treatment and response to therapy.
- Diagnostic imaging when medically appropriate.
This evaluation helps determine whether symptoms are associated with tendon pathology or another condition involving the joint, nerves, muscles, or surrounding structures.
What happens during a PRP procedure?
PRP treatment begins by drawing a small amount of the patient’s blood. The blood is then processed to separate and concentrate platelets from other components.
The resulting Platelet-Rich Plasma preparation is administered to the targeted area. The specific technique depends on the location and type of injury.
Because PRP is prepared from the patient’s own blood, it is an autologous treatment. As with any injection procedure, however, potential risks and expected benefits should be discussed with a qualified physician before treatment.
How long does recovery take after PRP therapy?
PRP is intended to support a biological healing process rather than provide immediate pain relief. Some patients may experience temporary soreness around the injection area following treatment.
Improvement, when it occurs, may develop gradually as the treated tissue responds over the following weeks or months. The timeline varies according to the type and severity of the tendon injury, overall health, activity level, and rehabilitation program.
Patients should follow individualized post-procedure instructions and avoid returning too quickly to activities that place excessive stress on the treated tendon.
Is physical therapy still important after PRP?
Regenerative medicine is often most useful as one component of a broader treatment strategy rather than as an isolated procedure.
Depending on the condition, physical therapy and progressive rehabilitation may help restore strength, flexibility, movement mechanics, and the tendon’s ability to tolerate normal physical loads.
Combining appropriate rehabilitation with regenerative treatment may help address both the injured tissue and the factors that contributed to the condition.
PRP therapy vs. temporary pain relief
Different treatments serve different purposes. Some medications or injections are primarily intended to control pain or inflammation, while regenerative approaches such as PRP are designed around supporting biological repair processes.
This does not mean PRP is automatically preferable to other treatments. The most appropriate approach depends on the diagnosis and individual patient.
A comprehensive evaluation helps determine whether conservative care, interventional pain management, regenerative medicine, or a combination of treatments is appropriate.
Who may not be a candidate for PRP therapy?
PRP is not suitable for every patient or every painful condition. Certain medical conditions, medications, active infections, blood disorders, or other health factors may affect whether treatment is appropriate.
For this reason, patients should undergo a medical evaluation and discuss their medical history, medications, previous treatments, and expectations before undergoing PRP therapy.
