Disease Description (Causes and Symptoms)
- Definition: Lateral epicondylitis (tennis elbow) is an overuse condition that causes pain due to repetitive microinjury and degenerative changes (tendinopathy) in the tendons of the wrist extensor muscle group attached to the outer elbow (lateral epicondyle).
- Causes/Pathophysiology: Repetitive wrist extension (bending backward) and forearm rotation cause microtears and degenerative changes (tendon fibrosis, neovascularization, etc.) in the tendon, triggering pain. Chronic tendon changes (tendinosis) are more common than acute inflammation.
- Main symptoms: Pain on the outer side of the elbow (especially worsening when lifting objects, bending the wrist backward, shaking hands, or twisting), localized tenderness, and reduced grip strength. Pain may be provoked on examination by the Cozen test (pain when making a fist and extending the wrist), the Mill test, and others.
Treatment Methods
- Conservative treatment (first-line choice for most patients)
- Rest and activity modification: Avoid repetitive movements and overuse that trigger pain.
- Use of braces: Symptoms may be relieved with an external epicondyle compression band (forearm strap), wrist brace, or similar device.
- Medication: Short-term pain control with oral/topical nonsteroidal anti-inflammatory drugs (NSAIDs).
- Physical therapy/exercise therapy: A rehabilitation program including stretching (of the wrist extensor muscles) and progressive strengthening, particularly eccentric exercise, is effective.
- Injection treatment: Local steroid injections may be effective for short-term pain relief but may have a high recurrence rate. PRP (platelet-rich plasma), autologous blood injections, extracorporeal shock wave therapy (ESWT), and other treatments may be considered in some patients, but the evidence and effectiveness vary.
- Invasive treatment
- Surgical treatment: Considered when conservative treatment (generally for 6–12 months or longer) does not lead to improvement. Removal of degenerated tissue from the lateral epicondyle tendon and reconstruction of the tendon attachment site (open or arthroscopic decompression/excision) may be performed. Only a small proportion of all patients require surgery.
- Lifestyle management and precautions
- Excessive immobilization (long-term casting) is not recommended — early activity and muscle-strength retraining are important for long-term recovery.
- Prevent recurrence by correcting work/exercise techniques (posture, equipment, racket grip/weight, etc.).
Checklist Before an Outpatient Visit (Including Items to Bring and Example Questions)
- Items to bring to the appointment
- A list of currently used medications and supplements
- A record of when the pain began (initial onset date and duration) and factors that worsen or relieve it
- Examples of pain intensity (pain scale, e.g., 0–10) and functional limitations (lifting objects, turning a doorknob, etc.)
- Results of previous tests (X-ray, ultrasound, MRI) or treatment records (medications, injections, physical therapy, surgery)
- Information about your occupation and exercise (frequency of at least once a week, equipment used, posture)
- Examples of useful questions to ask during the appointment (writing these down in advance can help with diagnosis and treatment planning)
- Was there a specific situation (movement or event) when the pain first started?
- Which movements cause the most pain? Which activities in your daily life feel uncomfortable?
- What treatments (physical therapy, injections, etc.) have you received before, and what were the results?
Examples of General Questions to Ask the Doctor
- What are the expected effects and side effects of this medication (or injection)?
- In my condition, how likely is improvement with conservative treatment (prognosis)? How long is the expected treatment period?
- I need to continue working or exercising. What restrictions or changes to my work environment are necessary?
- If surgery is necessary, at what point would you recommend it, and what are the recovery period and expected outcome after surgery?
Examples of Condition-Specific Questions
- If a steroid injection is recommended: "Can a steroid injection provide short-term relief? What is the risk of recurrence, and what effect could it have on long-term tendon changes?"
- Regarding rehabilitation/exercise: "Which specific stretches and strengthening exercises (for example, eccentric exercises) should I start, when should I start them, and at what intensity? What steps are needed to return fully to my daily work?"
Additional Information
- Diagnosis is mainly based on clinical findings. X-rays are used to rule out other lesions, while ultrasound and MRI are used to identify tendon changes and assess severity.
- Most cases improve with conservative treatment, but if symptoms persist for a long time, consult a specialist and review the treatment plan.
