Achilles Tendon Tear or Rupture

What Is an Achilles Tendon Tear?

Sudden Loss of Power in the Ankle Due to Tendon Rupture. The Achilles tendon is the largest and strongest tendon in the human body, connecting the calf muscles (gastrocnemius and soleus) to the heel bone (calcaneus). A tear or rupture of the Achilles tendon is a serious injury that often results in an immediate loss of strength and difficulty with walking or pushing off the foot. This injury typically occurs suddenly during sports or physical activity involving sudden acceleration or jumping.

Causes and Risk Factors

  • Sudden pivoting, jumping, or sprinting
  • Abrupt increase in physical activity
  • Direct trauma or a misstep from a height
  • Use of certain medications (e.g., fluoroquinolone antibiotics, corticosteroids)
  • Middle-aged males participating in recreational sports
  • Calf tightness or prior tendon degeneration

Symptoms

  • Sudden, sharp pain in the back of the ankle or calf
  • Sensation of being “kicked” or “struck” in the heel
  • Audible “pop” or snapping sound at the time of injury
  • Swelling and bruising near the heel
  • Inability to push off the foot or rise on toes
  • Visible gap in the tendon above the heel

Diagnosis

  • Physical exam:
    • Thompson test (squeezing the calf should cause foot movement—absent with rupture)
  • MRI or ultrasound to confirm tear and assess severity
  • X-rays may be used to rule out associated bone injury

Treatment

Non-Surgical Treatment

  • Best suited for partial tears or low-demand patients
  • Functional bracing in plantarflexion (toe-pointed position)
  • Progressive rehab protocol over several months
  • Risk of re-rupture may be slightly higher than with surgery

Surgical Treatment

  • Often recommended for active individuals and complete ruptures
  • Open or minimally invasive techniques to reattach tendon ends
  • May use sutures, anchors, or grafts if tendon quality is poor
  • Reduces risk of re-rupture and improves strength recovery in most cases

Recovery Timeline

Initial healing and immobilization: 2–4 weeks

Gradual weight-bearing and physical therapy: 6–12 weeks

Full activity return (including sports): 6–9 months

Early rehab protocols often lead to improved outcomes
