Tennis Elbow (Lateral Epicondylitis)

Tennis elbow is a common overuse injury affecting the tendons on the outside of the elbow. Despite its name, it affects many people who don’t play tennis, often resulting from repetitive work or daily activities. Our evidence-based approach provides effective, lasting relief.

Understanding Tennis Elbow

What Happens

• Tendon Degeneration: More than just inflammation
• Microtears: Repetitive stress causes tissue damage
• Failed Healing: Poor blood supply impairs recovery
• Pain Sensitization: Nervous system becomes hypersensitive

Common Causes

• Repetitive wrist extension
• Heavy computer use
• Manual labor and tools
• Racquet sports technique issues
• Sudden activity increase
• Poor workplace ergonomics

Symptoms

Primary Complaints

• Pain on outside of elbow
• Weakness gripping objects
• Pain with wrist movements
• Difficulty holding coffee cup
• Pain shaking hands
• Night pain in severe cases

Functional Impact

• Difficulty with work tasks
• Problems lifting objects
• Pain turning doorknobs
• Reduced sports performance
• Daily activity limitations

Assessment

Clinical Tests

• Cozen’s Test: Resisted wrist extension
• Mill’s Test: Passive wrist flexion
• Maudsley’s Test: Resisted middle finger extension
• Grip Strength: Objective weakness measurement

Contributing Factors

• Neck and shoulder involvement
• Nerve irritation
• Muscle imbalances
• Technique errors
• Equipment issues

Evidence-Based Treatment

Exercise Therapy (Most Effective)

• Eccentric Strengthening: Gold standard treatment
• Isometric Loading: Early phase pain relief
• Progressive Resistance: Gradual tendon loading
• Grip Strengthening: Functional improvement

Manual Therapy

• Elbow joint mobilization
• Soft tissue release
• Neural mobilization
• Cervical spine treatment
• Myofascial release

Additional Treatments

• Dry Needling: Trigger point release
• Taping: Offloading techniques
• Ice Therapy: Pain management
• Activity Modification: Ergonomic changes

Treatment Phases

Phase 1: Pain Reduction (Weeks 1-2)

• Relative rest (not complete rest)
• Isometric exercises
• Ice for pain relief
• Gentle stretching
• Activity modification

Phase 2: Loading (Weeks 2-6)

• Eccentric exercise program
• Progressive strengthening
• Flexibility exercises
• Technique correction
• Gradual activity increase

Phase 3: Strengthening (Weeks 6-12)

• Advanced strengthening
• Sport/work-specific exercises
• Power development
• Endurance training
• Prevention strategies

Exercise Program

Key Exercises

• Tyler Twist: Eccentric wrist extensor strengthening
• Isometric Holds: Pain relief and early loading
• Grip Strengthening: Progressive resistance
• Shoulder Stability: Kinetic chain exercises
• Stretching: Wrist flexors and extensors

Exercise Prescription

• 3 sets of 15 repetitions
• Daily performance recommended
• Progressive load increase
• Pain monitoring (acceptable: 3-4/10)
• Consistency crucial for success

Work and Sport Modifications

Office Workers

• Ergonomic mouse and keyboard
• Regular stretch breaks
• Posture optimization
• Technique modification
• Workstation setup review

Manual Workers

• Tool grip modifications
• Vibration reduction
• Task rotation
• Proper lifting techniques
• Protective equipment

Tennis Players

• Racquet weight and grip size
• String tension adjustment
• Technique analysis and correction
• Gradual return to play
• Preventive strengthening

Common Treatment Mistakes

• Complete rest (delays healing)
• Cortisone injections as first line
• Ignoring contributing factors
• Aggressive stretching when acute
• Returning to activity too quickly
• Not completing full rehabilitation

Injection Therapy Considerations

When Considered

• Failed conservative management (3+ months)
• Severe pain limiting function
• As adjunct to exercise therapy
• Never as sole treatment

Types and Evidence

• Cortisone: Short-term relief, worse long-term outcomes
• PRP: Mixed evidence, expensive
• Autologous Blood: Some positive evidence

Prevention Strategies

• Regular strengthening exercises
• Proper warm-up before activities
• Technique optimization
• Equipment appropriate for level
• Gradual activity progression
• Early treatment of symptoms

Expected Outcomes

Recovery Timeline

• Weeks 1-2: Initial pain reduction
• Weeks 2-6: Functional improvement
• Weeks 6-12: Return to activities
• 3-6 months: Full recovery typical

Success Rates

• 80-90% respond to exercise therapy
• Better outcomes with early treatment
• Recurrence reduced with complete rehab
• Surgery rarely needed (<5%)

When to Seek Treatment

• Pain lasting more than 2 weeks
• Weakness affecting daily tasks
• Night pain or rest pain
• Failed self-management
• Recurring episodes
