What Is Foot Drop?
Foot drop — the inability to raise the front part of the foot during walking — is a disabling condition resulting from weakness or paralysis of the muscles that dorsiflex (lift) the ankle. The characteristic “steppage gait” — lifting the knee high to clear the foot from the ground — is the hallmark of foot drop and places significant energy demands on the entire lower extremity.
While AFOs (ankle-foot orthoses) provide mechanical assistance, tendon transfer surgery offers the possibility of active, muscle-powered correction without relying on an external brace. At Balance Foot & Ankle in Howell and Bloomfield Township, Michigan, we evaluate foot drop patients to determine appropriate candidacy for surgical correction.
Causes of Foot Drop
Foot drop results from dysfunction anywhere along the neural pathway controlling the tibialis anterior and extensor muscles. Common causes include peroneal nerve palsy from knee or hip surgery, trauma, or prolonged compression; lumbar disc herniation compressing L4-L5 nerve roots; central nervous system conditions (stroke, multiple sclerosis, ALS); Charcot-Marie-Tooth disease; and compartment syndrome aftermath. The prognosis for recovery depends greatly on the cause — some causes are reversible while others result in permanent muscle loss.
When Tendon Transfer Is Considered
Tendon transfer for foot drop is considered when: the neurological injury is permanent or plateau has been reached without recovery, voluntary motor function exists in suitable donor muscles, the ankle joint is flexible (no fixed equinus contracture), and the patient understands the rehabilitation requirements. Surgery is not appropriate when recovery is still possible (premature transfer would eliminate potential for return of natural function) or when severe, fixed deformities require bony correction first.
The Tibialis Posterior Tendon Transfer
The most established tendon transfer for foot drop uses the tibialis posterior tendon — which normally plantarflexes and inverts the foot — rerouted through the interosseous membrane to the dorsal foot, where it can power dorsiflexion. This transforms a deforming force into a corrective one. The procedure requires meticulous surgical technique to route the tendon with appropriate tension and direction to achieve balanced dorsiflexion without excessive inversion or eversion.
Alternative transfers using the peroneus longus or flexor digitorum longus may be employed depending on which muscles are available and the specific pattern of weakness present.
Recovery and Rehabilitation
Recovery from tendon transfer surgery requires extensive rehabilitation that is more demanding than most orthopedic procedures because the brain must learn to use the transferred tendon for a completely new function. Immobilization in a cast for 6-8 weeks allows tendon healing. Subsequent physical therapy involves motor re-education — systematically training the patient to activate the transferred tendon in its new role. This neurological reprogramming process takes 6-18 months and requires dedicated patient effort. Most patients achieve significant functional improvement, with many able to discard or significantly reduce AFO usage.
Realistic Expectations
Tendon transfer for foot drop is not a procedure that restores normal gait overnight — it is a functional reconstruction that requires patient commitment to rehabilitation. The best outcomes occur in motivated patients with appropriate expectations, flexible joints, available donor muscles, and access to experienced physical therapy. A thorough consultation with your podiatric surgeon will clarify whether you are an appropriate candidate and what functional improvement you can realistically anticipate.
