PRP for Tennis Elbow (Lateral Epicondylitis): What the Evidence Shows

For tennis elbow, also called lateral epicondylitis, recent meta-analyses show a time-dependent difference between injection types: corticosteroid injections provide faster relief in the first month or two, while PRP (platelet-rich plasma) shows stronger pain and function results from about three to six months onward. Neither injection is uniformly better, and the right choice depends on your timeline, your tendon, and your goals. At Zest Regen Health in Columbia, Maryland, PRP is considered only after a medical evaluation confirms the diagnosis and determines it may be appropriate for you.

What tennis elbow is

Lateral epicondylitis is irritation of the tendons on the outside of the elbow, usually from repetitive gripping, lifting, or wrist extension. It is common in people who do repetitive work or play racquet sports, which is where the name comes from, but it can affect anyone. Pain typically worsens with gripping or lifting, and the condition can persist for months without treatment.

What the recent evidence shows

• A 2023 systematic review and meta-analysis in the Journal of Shoulder and Elbow Surgery found corticosteroids superior for pain and function at 1 month, but PRP superior for pain at 3 months and 6 months.
• A 2025 meta-analysis of 26 randomized trials including 1,877 patients found corticosteroids favored for pain at under 2 months, no significant difference between 2 and 6 months, and PRP favored beyond 6 months.
• A 2024 systematic review of randomized trials concluded both injections are effective, with corticosteroids better for short-term function and PRP better for long-term pain and function at 6 months and beyond.

What this means for your decision

If you need quick relief for an acute flare, a corticosteroid injection may act faster. If you want a longer-term approach after conservative care has stalled, PRP is the option the evidence increasingly favors. The decision also depends on your injection history, since repeated corticosteroids are limited, and on the specific state of your tendon after evaluation.

Who may be a candidate for PRP

• Adults with persistent elbow pain that has not improved with physical therapy or activity modification
• A diagnosis of lateral epicondylitis confirmed by examination
• Appropriate bloodwork and no reasons to avoid the procedure identified during evaluation
• Realistic expectations, since meaningful results typically take weeks to months rather than days

What a PRP session for tennis elbow involves

1. A small sample of your blood is drawn, similar to a routine blood test.
2. The sample is processed to concentrate the platelets.
3. The prepared PRP is injected into the affected tendon area under physician guidance.
4. Activity and recovery guidance is provided, with follow-up to review progress.

What to keep in mind

PRP is not a guaranteed cure, and individual results vary. Some patients improve meaningfully, others see modest change, and a share of elbows do best with continued physical therapy. Multiple sessions are sometimes recommended, and rehabilitation is part of the plan. No reputable clinic promises a specific result.
