The tibialis anterior is the main muscle that lifts the foot and ankle upward. Its tendon crosses the front of the ankle to the inside of the midfoot. A rupture is uncommon,1 and it is often missed because the pain can be mild: the main sign is often a sudden foot drop, with the foot slapping or the toes catching while walking.6,7 Younger people usually tear it in an injury, while older adults more often rupture a worn tendon with little or no trauma.4

At a glance

  • A sudden ‘foot drop’, foot slap or toe catching when walking
  • A lump at the front of the ankle where the torn tendon has pulled back
  • Often mistaken for a nerve problem or ankle sprain7,9
  • Surgery generally restores better function than a brace11
  • Early repair tends to give better results than late reconstruction12

Causes

  • Traumatic ruptures: a forceful pull or a cut, usually in younger patients (average age 39 in one series).4
  • Atraumatic (spontaneous) ruptures: degeneration of the tendon in older adults (average age 73),4 usually where the tendon glides under a band of tissue at the front of the ankle.5
  • Risk factors include diabetes, inflammatory arthritis, steroid use and previous injections near the tendon.

Symptoms

  • Weakness lifting the foot, a foot that slaps down or toes that catch when walking
  • A high-stepping (steppage) gait to clear the foot8
  • A tender lump in front of the ankle (the retracted tendon end)
  • Mild pain or swelling over the front of the ankle or inner midfoot

Because pain may be mild, many ruptures are diagnosed weeks or months later.6,7

Diagnosis

Dr. Dold checks ankle dorsiflexion strength, feels for the tendon and the gap, and watches you walk. Other toe-lifting tendons can partly compensate, which is why the diagnosis is easy to miss. A sudden foot drop can also come from a nerve problem, so the exam distinguishes the two.9 MRI or ultrasound confirms the rupture and shows how far the tendon has retracted.10

Non-surgical treatment

For less active patients or those with health risks for surgery, an ankle-foot orthosis (AFO) can control the foot drop, and some patients function well this way.14 Tendinopathy (degeneration without a full tear) is treated first with activity and shoe changes.3,21

Surgery

For most active patients, surgery gives better function than non-surgical care, with good results at any age.11 Mild residual weakness is common but rarely limits function.11

  • Direct repair: reattaching or sewing the tendon ends, ideally soon after injury. Ruptures repaired in the acute phase had better outcomes than late repairs,12 although one series found similar results with delayed repair.13
  • Reconstruction: for chronic ruptures with a gap, the tendon is bridged with a graft. Allograft and autograft reconstructions had similar outcomes,17 and hamstring autograft reconstruction allowed all patients to walk without a brace.18 A neighboring tendon (extensor hallucis longus) can also be transferred.19

After repair, function scores improved substantially in published series (for example, from 55.5 to 93.6),15,16 and patients were generally satisfied.15,20

Tendinopathy

Degeneration of the distal tendon without a complete tear can cause pain over the inner midfoot, often at night and in active walkers. Conservative care comes first;21 for those who don’t improve, decompression or debridement of the tendon reduced pain substantially.21,22

Recovery

  • After repair or reconstruction: a splint or cast, then a boot, with protected weight-bearing for several weeks, followed by physical therapy to restore strength and gait.
  • Most people walk without a brace afterward, though full strength can take many months.

Frequently asked questions

How do I know if I’ve ruptured my tibialis anterior tendon?

A sudden foot slap or toes catching when you walk, weakness lifting your foot and a lump at the front of the ankle are typical. Pain is often mild, so it’s easy to miss.

Is it a nerve problem or a tendon rupture?

Both can cause foot drop. An exam (and sometimes MRI or nerve studies) tells them apart; a palpable gap or lump at the front of the ankle points to the tendon.

Do I need surgery?

For active people, surgery generally gives better function. Some less active patients do well with an ankle-foot brace.

What if it’s been months?

Chronic ruptures can still be reconstructed with a tendon graft or transfer, though earlier repair tends to give better results.

How long is recovery?

Expect several weeks in a cast or boot, then months of therapy to rebuild strength.
