Achilles tendinopathy is defined as inflammation and degeneration of the Achilles tendon. It is one of the most common conditions affecting this area, particularly among athletes especially runners (both amateur and professional), due to overuse of the tendon. The Achilles tendon is the largest and strongest tendon in the human body, connecting the calf muscles to the posterior aspect of the heel. Despite its strength, it is vulnerable to injury because it receives its blood supply from surrounding tissues rather than having its own dedicated vascular system.
Causes of Achilles Tendinopathy
Factors responsible for the development of Achilles tendinopathy include:
- Overuse of the tendon
- Increase in training intensity
- Improper technique
- Inappropriate athletic footwear
- Short Achilles tendon
- Tight gastrocnemius muscles
- Cavus foot (high arch)
- Psoriatic arthritis
- Heel spur or Haglund’s deformity
Symptoms Accompanying Achilles Tendinopathy
Symptoms accompanying Achilles tendinopathy include:
- Pain in the affected area
- Difficulty in movement (e.g., climbing stairs, running)
- Tightness in the tendon
- Crepitus or crackling sensation during movement
- Loss of tendon strength
- Lump on the tendon or behind the heel bone
- Tenderness in the area
- Redness
- Increased warmth
- Swelling
Diagnosis and Treatment of Achilles Tendinopathy
For the diagnosis of Achilles tendinopathy, obtaining a detailed medical history and performing a thorough clinical examination are essential. Imaging studies, such as radiographs, ultrasound, or magnetic resonance imaging (MRI), may also be requested to fully evaluate the condition of the tendon.
Treatment of Achilles tendinopathy can be either conservative or surgical. Conservative management includes:
- Rest and limitation of activities that exacerbate symptoms
- Stretching exercises
- Pharmacological therapy
- Use of an immobilization splint (typically at night)
- Orthotic heel supports
- Use of shoes with a 2–4 cm heel lift
- Cryotherapy
- Weight loss (for overweight patients)
- Shockwave therapy
- Corticosteroid injections
- PRP (Platelet-Rich Plasma) injections
In severe cases, or when conservative management fails to achieve satisfactory results, surgical intervention may be indicated. The choice of surgical procedure depends on the underlying cause of the tendinopathy and the severity of the condition.Preventive measures include the use of appropriate athletic equipment, proper training intensity, and awareness of the body’s limits, which can reduce the risk of developing Achilles tendinopathy and its associated symptoms.
