Tennis elbow — known medically as lateral epicondylitis — is one of the most common and most under-treated causes of elbow pain in adults. Despite the name, fewer than 1 in 20 cases occur in tennis players. The vast majority happen in office workers, tradespeople, weekend athletes, and pickleball players — anyone whose forearm tendons take repeated load from gripping, lifting, or wrist extension.
At Modal Pain Management in Midtown Manhattan, Dr. Alex Movshis combines a focused clinical exam, bedside ultrasound, and an evidence-based treatment ladder that leads with PRP (platelet-rich plasma) and percutaneous tenotomy — interventions that address the underlying tendinopathy rather than just suppressing inflammation. Most patients are evaluated, diagnosed, and (when appropriate) treated in a single office visit.
This page covers what tennis elbow actually is, how it is diagnosed, why PRP is the preferred first-line injection for most patients, and the full evidence-based treatment ladder we use to get patients back to gripping, lifting, working, and playing without pain.
What Is Tennis Elbow?
Tennis elbow is a tendinopathy — a chronic, degenerative injury — of the common extensor tendon at the lateral epicondyle of the humerus (the bony bump on the outside of the elbow). The most commonly involved tendon is the extensor carpi radialis brevis (ECRB), with frequent involvement of the extensor digitorum communis. Despite the historical name “epicondylitis” (which implies inflammation), modern histological studies show that established tennis elbow is primarily a tendinosis — disorganized collagen fibers, microtears, and abnormal blood vessel ingrowth — rather than active inflammation. This is why pure anti-inflammatory treatment (rest, NSAIDs, cortisone) often provides incomplete or short-lived relief, and why treatments that stimulate tendon healing (PRP, eccentric loading, percutaneous tenotomy) increasingly dominate the evidence base.
The classic patient profile is age 35–55 with repetitive forearm load — but tennis elbow is increasingly common in younger office workers due to mouse use, in pickleball and padel players (the fastest-growing racquet sport demographics), and in CrossFit and weight training enthusiasts who load the forearm in pronation.
Tennis Elbow vs. Other Causes of Elbow Pain
Lateral elbow pain has several possible causes that look similar on the surface but require different treatment. At Modal Pain Management we systematically rule out each one:
- Tennis elbow (lateral epicondylitis) — pain on the outer elbow, reproduced by Cozen’s, Mill’s, and Maudsley’s tests; tenderness directly over the lateral epicondyle.
- Golfer’s elbow (medial epicondylitis) — pain on the inner elbow involving the wrist flexor tendons. Same treatment principles, opposite location.
- Posterior interosseous nerve syndrome / radial tunnel syndrome — pain about 3–4 cm distal to the lateral epicondyle (rather than directly over it), with deep aching that worsens at night; reproduced by resisted middle-finger extension and resisted forearm supination.
- Cervical radiculopathy (C6/C7 nerve root) — referred pain from the neck into the lateral elbow and forearm; often misdiagnosed as tennis elbow when the pain pattern is atypical or persistent.
- Lateral collateral ligament injury — instability with lateral pivot stress, usually after trauma.
- Posterolateral elbow plica — inflamed synovial fold catching during elbow flexion-extension; less common but a real entity.
- Synovitis or early osteoarthritis of the radiocapitellar joint — joint-line pain rather than tendon-attachment pain.
A focused exam plus bedside ultrasound resolves most of these on the first visit. MRI is reserved for atypical or refractory cases.
Diagnosis at Modal Pain Management
A first-visit tennis elbow evaluation at Modal Pain Management includes:
- Focused history — onset (acute vs. insidious), occupational and athletic exposures (mouse use, racquet sport, gripping demands), prior treatments and their effect, and any neck or hand symptoms that might suggest a different diagnosis.
- Physical examination — inspection, palpation of the lateral epicondyle and surrounding structures, range of motion, grip strength testing, and the three classic provocative tests (Cozen’s, Mill’s, Maudsley’s).
- Bedside ultrasound — visualization of the common extensor tendon to grade severity (mild tendinosis, moderate tendinosis with partial tear, full-thickness tear), identify calcifications, and assess for neovascularization. This determines both prognosis and the optimal treatment.
- Targeted imaging — X-ray if there is concern for a calcification or arthritis; MRI for atypical presentations or before considering surgery.
The single-visit diagnostic workflow is one of the main reasons patients with chronic, undifferentiated lateral elbow pain often achieve faster definitive answers at Modal Pain Management than through serial referral.
Image-Guided Treatment Ladder
The evidence-based treatment for tennis elbow follows a structured ladder. Most patients move through it from top to bottom; some can start at a higher rung based on chronicity and ultrasound findings.
Step 1: Conservative Treatment (Weeks 0–6)
For most patients with acute or mild symptoms, the first 4–6 weeks emphasize load reduction and the start of structured eccentric exercise:
- Activity modification — temporary reduction in gripping, lifting palm-down, racquet sport, and aggravating workplace tasks.
- Counterforce brace placed approximately 1 inch (one finger-breadth) below the elbow during unavoidable load — this redistributes force away from the inflamed tendon insertion.
- NSAIDs for short-term symptom control if you tolerate them (naproxen 500 mg twice daily for 7–10 days, with food).
- Eccentric strengthening — slow, lengthening contractions of the wrist extensors using a 1–3 lb dumbbell (3 sets of 15, daily) or the Tyler Twist exercise with a FlexBar — has the strongest single-intervention evidence base for tennis elbow.
- Workplace and equipment ergonomics — vertical mouse, ergonomic keyboard, racquet weight and string tension review, grip technique coaching.
About 60–70% of acute cases resolve with this approach within 6–12 weeks.
Step 2: PRP (Platelet-Rich Plasma) Injection — Preferred First Injection (Weeks 6–12+)
For patients whose pain persists beyond 4–6 weeks of conservative care, or for chronic tendinopathy on ultrasound, PRP injection is the preferred first injection in the modern evidence base. PRP uses a small sample of the patient’s own blood, processed in-office to concentrate the platelets, then injected directly into the damaged tendon under real-time ultrasound guidance. The growth factors released by the platelets stimulate genuine tendon healing rather than simply suppressing inflammation.
PRP takes longer to work than cortisone (full effect at 6–12 weeks, with a temporary increase in soreness in the first 1–2 weeks as the healing response begins), but multiple high-quality studies show 70–85% of patients with chronic tennis elbow achieve durable relief at 12+ months — substantially better long-term outcomes than cortisone. PRP is typically not covered by insurance and has an out-of-pocket cost, which we discuss transparently before scheduling.
Step 3: Percutaneous Tenotomy for Refractory Cases (Months 3–6+)
For chronic, refractory tennis elbow (>6 months) that has not adequately responded to conservative care and PRP, ultrasound-guided percutaneous tenotomy is the next step before surgical referral. This is a minimally invasive office procedure in which a small needle (or a dedicated tenotomy device) is used under ultrasound guidance to mechanically break up the disorganized scarred tendon tissue and stimulate a healing response. It is performed under local anesthesia in approximately 20 minutes and has a 70–80% durable success rate in chronic cases that have failed other treatments. Recovery typically takes 4–8 weeks.
When Cortisone Is Used
Corticosteroid injection is appropriate in selected cases — typically acute, severe pain where a patient absolutely must function in the next 2–4 weeks (a critical work or athletic event). Cortisone provides faster short-term relief but is associated with higher 6- and 12-month recurrence rates, and repeated cortisone injections can weaken the tendon. We use cortisone selectively rather than as a first-line treatment, and never repeat it in the same tendon within 3 months.
When Surgery Is Considered
Surgery (open or arthroscopic ECRB tendon release) is reserved for the small subset of patients (<5%) with chronic, severe tennis elbow that has not responded to 6–12 months of structured non-operative treatment including PRP and tenotomy. We coordinate referrals to NYC orthopedic upper-extremity specialists when surgery becomes appropriate — but the great majority of patients avoid this pathway.
Physical Therapy and Self-Care
Image-guided injection accelerates pain relief, but durable recovery requires addressing the underlying tendon and biomechanics. A targeted rehabilitation program for tennis elbow typically includes:
- Eccentric wrist extensor strengthening — the cornerstone of evidence-based tennis elbow rehab. The Tyler Twist (FlexBar) or dumbbell eccentrics, progressed gradually over 6–12 weeks.
- Forearm and grip strengthening progression — slow eccentric grip, then concentric grip, then dynamic grip as pain allows.
- Shoulder and scapular stabilization — weakness in the rotator cuff and scapular stabilizers shifts load distally onto the elbow tendons; addressing this prevents recurrence.
- Workplace ergonomic evaluation — mouse, keyboard, monitor height, chair position, vertical mouse trial.
- Equipment review for racquet sport athletes — racquet weight, string tension, grip size; for golfers, club fitting and grip technique.
- Self-care — counterforce brace during load, ice for 15 minutes after activity, gradual return-to-sport progression.
Most patients see meaningful improvement within 6–12 weeks of starting structured rehab combined with appropriate injection.
When to Seek Specialist Care
See a pain specialist for tennis elbow evaluation if any of the following apply:
- Lateral elbow pain that has not improved with 4–6 weeks of activity modification, NSAIDs, and a counterforce brace.
- Pain that is interfering with work, sleep, or daily activities (gripping a coffee cup, opening a jar, shaking hands).
- Symptoms that have been present for more than 3 months despite home treatment.
- A previous episode that resolved and has now recurred.
- Pain that is atypical (located more than 3 cm distal to the elbow, worse at night, associated with neck symptoms or hand numbness) — these patterns suggest a different diagnosis that needs to be ruled out.
Red-flag symptoms — sudden severe pain after a “pop,” visible deformity, bruising, complete loss of grip strength, or numbness in the hand — require prompt evaluation rather than an outpatient tennis elbow workup.
Why Modal Pain Management for Tennis Elbow in NYC
Modal Pain Management is a focused, physician-owned interventional pain practice in Midtown Manhattan. Dr. Alex Movshis is dual board-certified in Anesthesiology and Pain Medicine, completed pain medicine fellowship training at NYU Langone, and is on staff at NewYork-Presbyterian and Lenox Hill Hospital. NPI 1942741160 — see our evidence and credentials page and the physician bio for full verification.
Three things differentiate tennis elbow care at Modal Pain Management:
- Single-visit diagnosis with bedside ultrasound. A focused exam plus real-time ultrasound imaging of the common extensor tendon — at the consultation visit — eliminates the back-and-forth of separate imaging appointments and provides immediate clarity on the type and severity of injury.
- PRP-first treatment philosophy. The evidence base for chronic tennis elbow now favors PRP over cortisone for long-term outcomes. We use PRP as the first-line injection for most patients and reserve cortisone for selected acute scenarios — with transparent up-front discussion of cost, expected timeline, and realistic outcomes.
- Coordinated medical, interventional, and rehabilitation plan. We work directly with NYC physical therapists who specialize in upper-extremity tendinopathy and coordinate care so that injection benefits convert into durable recovery, not a temporary reprieve.
