Tennis Elbow Treatment in Raleigh, NC

What Is Tennis Elbow?

Tennis elbow — formally lateral epicondylitis or lateral epicondylar tendinopathy — is degeneration of the extensor carpi radialis brevis (ECRB) tendon at its attachment on the lateral epicondyle (the bony bump on the outside of the elbow). Despite the name, less than 5% of cases are actually caused by tennis. The majority occur in manual workers, computer users, and — increasingly — pickleball players in Raleigh and the surrounding Wake County communities.

The underlying pathology is tendinosis — degenerative changes in the tendon collagen — rather than acute inflammation. This distinction matters enormously for treatment: cortisone suppresses inflammation but doesn't address the underlying degeneration, which is why it produces worse outcomes than PRP at 12 months.

Symptoms

• Pain and tenderness at the outer elbow — directly over the lateral epicondyle
• Pain radiating down the outer forearm toward the wrist
• Weak grip and pain with shaking hands
• Pain when lifting objects, turning a door handle, or gripping a pickleball paddle
• Pain with wrist extension against resistance
• Morning stiffness in the elbow and forearm

Common Causes in Raleigh-Area Patients

• Pickleball: The dinking motion, backhand drive, and repetitive gripping are the leading cause of new tennis elbow cases in our Wake County practice. See our Pickleball Elbow Guide.
• Computer use: Sustained wrist extension while using a mouse loads the ECRB continuously
• Manual work: Carpentry, plumbing, painting — any repetitive gripping and forearm rotation
• Tennis: The backhand with poor technique — especially a one-handed backhand with a leading elbow
• Golf: Impact and divot shots, especially with poor swing mechanics

Diagnosis

Tennis elbow is a clinical diagnosis. Dr. Chambers will perform a focused physical examination including:

• Lateral epicondyle palpation — reproduces the characteristic tenderness
• Cozen's test — resisted wrist extension with the elbow extended
• Mill's test — passive wrist flexion with the elbow extended
• Grip strength testing — typically reduced 10–40% on the affected side

Ultrasound or MRI can confirm ECRB tendinosis and guide PRP injection placement when indicated. Imaging is not required for the initial diagnosis but is helpful for surgical planning or when the presentation is atypical.

Treatment

1. Physical Therapy with Eccentric Exercises

The most evidence-based first-line treatment. Eccentric wrist extension exercises — where the muscle contracts while lengthening — progressively remodel the degenerated collagen. The Tyler Twist (FlexBar exercise) is a well-studied eccentric program shown to reduce pain by 81% versus conventional PT. Combined with activity modification and a counterforce brace, PT resolves most cases.

2. Counterforce Brace

A narrow strap worn 2–3 cm below the lateral epicondyle (not on the elbow) during activity. By distributing load across the forearm muscles, it reduces the stress on the degenerated ECRB tendon attachment. Inexpensive and effective — every pickleball player with tennis elbow should wear one.

3. PRP Injection (For Chronic or Resistant Cases)

PRP is indicated when PT has not produced adequate improvement after 6–8 weeks. Ultrasound-guided injection delivers concentrated growth factors (PDGF, TGF-β, VEGF) directly to the area of tendinosis. Multiple RCTs show PRP is superior to cortisone at 6 and 12 months. Plan for a 48–72 hour post-injection flare and 6–12 weeks to full benefit.

4. Cortisone Injection

Appropriate for severe acute pain flares that prevent PT from beginning. Provides faster short-term relief than PRP but produces worse outcomes at 12 months. Multiple cortisone injections in the same tendon are associated with tendon weakening and should be avoided.

5. Surgery (ECRB Debridement)

Reserved for the 10–15% who fail 6+ months of genuine conservative treatment including PT and PRP. The degenerated ECRB tendon tissue is removed arthroscopically or through a small open incision. Success rate approximately 85%. Return to full activity in 12–16 weeks.
