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
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.
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.
