Tendonitis is the inflammation or irritation of a tendon, causing sharp pain, swelling, and joint stiffness. It commonly affects the shoulder, elbow, knee, and ankle due to repetitive strain or sudden injury. Physiotherapists treat tendonitis using a tailored, non-invasive approach. This includes targeted loading exercises, manual therapy, and lifestyle adjustments to restore strength, improve tissue flexibility, and prevent long-term recurrence.
What Is Tendonitis and What Causes It?
Tendonitis is the painful inflammation of a tendon, which is the thick cord connecting muscle to bone. It is primarily caused by repetitive movement, sudden increases in activity, or improper biomechanics during work and sports. This physical strain creates microscopic tears in the tendon fibers that trigger an inflammatory response.
While anyone can develop tendonitis, certain factors significantly increase your daily risk:
Repetitive strain: Doing the same movement for hours during sports or office work.
Sudden load changes: Rapidly increasing exercise intensity, weight, or duration.
Poor mechanics: Using incorrect form while lifting weights or performing tasks.
Ageing factors: Tendons naturally lose their elasticity and flexibility over time.
Unsupportive gear: Wearing worn-out shoes or using improperly fitted sports equipment.
What Are the Most Common Types of Tendonitis?
The most common types of tendonitis include Achilles, patellar, rotator cuff, and elbow tendonitis (tennis or golfer's elbow). Each type is named after the specific tendon affected and is usually tied to activities that repeatedly stress that unique area of the body.
The table below breaks down the most frequent forms of this condition:
| Type of Tendonitis | Affected Body Part | Common Triggers & Activities |
|---|---|---|
| Achilles Tendonitis | Back of the heel/ankle | Running, jumping, sudden sprinting |
| Patellar Tendonitis | Just below the kneecap | Basketball, volleyball ("jumper's knee") |
| Rotator Cuff Tendonitis | Shoulder joint | Swimming, painting, overhead lifting |
| Lateral Epicondylitis | Outer elbow | Tennis, typing, repetitive gripping |
| Medial Epicondylitis | Inner elbow | Golf, throwing sports, hammering |
What Are the Main Symptoms of Tendonitis?
The main symptoms of tendonitis are localized pain, mild swelling, tenderness, and a grating sensation during movement. The pain typically builds up gradually and feels like a dull ache. It is usually most severe first thing in the morning or immediately after physical activity.
Recognizing these symptoms early can prevent the condition from worsening into a chronic issue:
Dull ache: A persistent pain concentrated around the affected joint.
Tenderness: Sharp discomfort when you touch or press on the tendon.
Stiffness: Difficulty moving the joint, especially after periods of rest.
Mild swelling: Visible puffiness or redness around the injured area.
Crepitus: A crackling or grating feeling when moving the joint.
How Do Physiotherapists Diagnose Tendonitis?
Physiotherapists diagnose tendonitis through a comprehensive physical examination, a detailed medical history, and specific movement tests. They assess your range of motion, muscle strength, and localized tenderness. In most standard cases, expensive imaging like ultrasound or MRI scans is not required for a clear diagnosis.
How Do Physiotherapists Treat Tendonitis?
Physiotherapists treat tendonitis using a combination of progressive exercise therapy, manual therapy, and tailored patient education. They design a customized recovery plan that moves you away from absolute rest and toward progressive loading. This approach reduces pain while actively rebuilding the tendon's capacity to handle physical stress.
Physiotherapy treatment is multi-faceted and shifts as your healing progresses:
Progressive loading: Safely stressing the tendon to stimulate tissue repair and growth.
Manual therapy: Using hands-on massage and joint mobilization to relieve tight muscles.
Activity modification: Replacing painful movements with safe alternatives rather than stopping all activity.
Biomechanical correction: Retraining your posture, gait, or lifting form to remove uneven strain.
Pain management: Using ice, heat, or taping methods to control early-stage discomfort.
What Exercises Help Heal Tendonitis?
Isometric and eccentric exercises are the most effective movements used by physiotherapists to heal tendonitis. Isometrics involve holding a muscle contraction still to reduce pain, while eccentrics focus on slowly lengthening the muscle under tension. These specific movements trigger cellular repair within the damaged tendon fibres.
How Long Does Tendonitis Take to Heal With Physio?
Mild tendonitis typically takes 4 to 6 weeks to heal with consistent physiotherapy, while chronic cases can take 3 to 6 months. Healing times depend heavily on how long you have had the symptoms, your overall health, and how closely you follow your prescribed home exercise routine.
What Is the Difference Between Tendonitis and Tendinopathy?
Tendonitis is an acute, short-term inflammatory condition, whereas tendinopathy refers to the chronic degeneration of a tendon without active inflammation. Tendonitis happens suddenly after an injury, while tendinopathy develops over months from repetitive overloading, causing the structural collagen fibres within the tendon to break down.
Understanding this difference completely changes how the condition is managed:
Tendonitis features: Active inflammation, sudden onset, and responds well to short-term anti-inflammatories.
Tendinopathy features: No active inflammation, long-term wear and tear, and requires structural loading to heal.
Treatment shift: Tendonitis requires short-term calming strategies, whereas chronic tendinopathy requires heavy, slow resistance training.
Can You Prevent Tendonitis from re-occuring?
Yes, you can prevent tendonitis from returning by maintaining good muscle strength, warming up properly, and avoiding sudden spikes in your workout intensity. Ensuring your body has adequate recovery time between heavy sessions is the most effective way to keep your tendons healthy and resilient over time.
To keep your tendons safe during daily life and exercise, practice these habits:
Gradual progression: Follow the "10% rule" by never increasing your weekly training volume by more than 10%.
Regular strength training: Keep the muscles surrounding your joints strong to absorb impact.
Cross-training: Mix up your activities to avoid overworking the same muscle groups every day.
Ergonomic setups: Adjust your office chair, desk, and keyboard to reduce constant micro-strain.
Stay hydrated: Drink plenty of water to keep your tendon tissues elastic and well-lubricated.
