Whether you’re a pro or just a very enthusiastic hobbyist, nothing can derail this year’s goal like a painful sports injury. After all, a big part of success is working through the pain – but ignoring our body’s alert signs can easily create bigger problems down the road.
Tendonitis (sometimes also known as tendinitis or tendinopathy) is a particularly common red flag. However, platelet-rich plasma for tendonitis may be considered for symptom improvement and functional recovery in selected tendon conditions, depending on the diagnosis, severity, and available evidence.
Dr. Nazarian’s Clinical Perspective on PRP for Tendon and Sports Injuries
Written and medically reviewed by David Nazarian, MD — Board Certified in Internal Medicine and Medical Director of PRP Treatment Beverly Hills.
I have had the opportunity to treat many patients with sports-related tendon injuries over the years. Two of the most common conditions I see are tennis elbow and golfer’s elbow.
PRP for Tendon Injuries: Treatment Selection Guide
| Condition | When PRP may be considered |
|---|
| Tennis elbow / lateral epicondylitis | Persistent symptoms despite appropriate conservative treatment. |
| Golfer’s elbow / medial epicondylitis | Selected chronic tendinopathy after diagnosis is confirmed. |
| Patellar or Achilles tendinopathy | Selected chronic cases where rehabilitation alone has not been sufficient. |
| Rotator cuff tendinopathy or partial injury | Selected cases depending on tear pattern, severity and function. |
| Complete tear or major retraction | PRP should not delay surgical or specialist evaluation when surgery is indicated. |
My clinical approach: I am most interested in PRP when the tendon diagnosis is clear, symptoms have persisted despite appropriate rehabilitation, and the tendon still has a realistic capacity to respond. — David Nazarian, MD
Physician Answers: PRP for Tendon Injuries
Which tendon problems are commonly treated with PRP?
PRP has been studied for conditions such as lateral epicondylitis, medial epicondylitis, patellar tendinopathy, Achilles tendinopathy, and selected rotator-cuff or other tendon disorders. The quality of evidence varies by tendon and protocol.
When do I consider PRP?
I am more likely to consider PRP when the diagnosis is clear, symptoms persist despite appropriate rehabilitation or other conservative care, and there is not a complete tear or another condition that would make a different treatment more appropriate.
Does PRP guarantee tendon healing?
No. PRP may improve symptoms in selected patients, but it should not be presented as guaranteed tendon regeneration or a replacement for surgery when surgery is clearly indicated.
I am most interested in PRP when the diagnosis is clear, symptoms have persisted despite appropriate conservative treatment, and the tendon still has a realistic capacity to respond; a complete tear, major retraction, or another diagnosis may require a different approach.
Tennis elbow, also called lateral epicondylitis or lateral elbow tendinopathy, usually causes pain on the outside of the elbow. The extensor carpi radialis brevis, or ECRB tendon, is commonly involved, and patients often have very localized tenderness near the lateral epicondyle with pain during gripping, lifting, racquet sports, or repetitive wrist extension. Although the condition is often called tendinitis, chronic cases commonly involve tendinopathy rather than only acute inflammation.
Golfer’s elbow, or medial epicondylitis, causes pain on the inside of the elbow where the wrist flexor and pronator tendons attach. Repetitive gripping, golf, tennis, weight training, and occupational activity can all contribute. In appropriately selected patients, I have used targeted PRP injections for persistent tendon problems and have seen meaningful improvement over time.
I have also treated Achilles tendinopathy with PRP. Achilles problems can range from chronic tendon degeneration to partial or complete tearing, so the diagnosis and severity matter. When the examination is not enough to define the injury, I have ordered ultrasound or MRI to evaluate the tendon and surrounding structures more clearly.
PRP is not an instant pain-relief injection. Platelets contain signaling proteins, growth factors, and cytokines that are being studied for their role in local tissue responses, so improvement, when it occurs, generally takes time. I also emphasize rehabilitation, activity modification, and appropriate tendon loading rather than relying on the injection alone.
