Foot Drop / Peroneal Nerve Surgery
Foot drop — difficulty lifting the front of the foot — often results from injury or compression of the peroneal nerve. When it does not recover on its own, surgery to decompress, repair, or transfer the nerve can restore function.
Peripheral nerve pathway
From injury assessment to reconstruction
Diagnosis
Define the injured nerve, severity, timing, and pattern of weakness or pain.
Timing
Determine whether observation, urgent repair, or reconstruction is most appropriate.
Reconstruction plan
Choose repair, grafting, decompression, tumor surgery, or nerve transfer.
Recovery
Track regeneration, therapy progress, pain control, and functional return.
Time-sensitive repair
Early specialist review can preserve options for nerve repair, grafting, or transfer.
Anatomic diagnosis
Exam, imaging, EMG, and surgical history help define the level and severity of injury.
Function-first planning
Treatment is chosen around realistic goals for movement, sensation, pain, and independence.
Overview
Foot drop is difficulty lifting the front of the foot, which causes the toes to drag and can lead to tripping and falls. It most often results from injury or compression of the peroneal nerve, which controls the muscles that raise the foot. When foot drop does not recover on its own, surgery can restore function.
When to see a peripheral nerve surgeon
Persistent foot drop should not simply be waited out. Because nerve recovery is time-sensitive, an evaluation should be sought when foot drop does not improve, follows an injury or surgery, or is associated with a nerve lump or worsening weakness.
Symptoms
- Difficulty lifting the front of the foot
- Toes dragging when walking; tripping or falls
- A high-stepping gait to clear the foot
- Numbness over the top of the foot
- Weakness that follows injury, surgery, or pressure at the knee
Causes
- Compression or entrapment of the peroneal nerve at the knee
- Trauma or stretch injury
- Nerve tumor
- Prolonged pressure (for example, from positioning or crossing the legs)
- Injury during a surgical procedure
Treatment
- Decompression of an entrapped peroneal nerve
- Nerve repair or grafting after injury
- Nerve transfer to restore foot lift
- Tendon transfer in selected cases
- Coordination with bracing and physical therapy
Dr. Barone’s approach
Dr. Barone evaluates foot drop with examination, imaging, and nerve studies to identify the cause and location, then tailors treatment — preserving the limited window for nerve recovery.
Frequently asked questions
What causes foot drop? +
Foot drop usually results from a problem with the peroneal nerve, which lifts the foot and toes. Common causes include compression at the knee, trauma, stretch injury, a nerve tumor, prolonged pressure, or injury during surgery. Identifying the cause and location guides treatment.
Will foot drop go away on its own? +
Some cases — especially mild compression — recover with time, bracing, and therapy. Others do not, particularly after significant nerve injury. Because the window for nerve recovery is limited, persistent foot drop should be evaluated by a peripheral nerve surgeon rather than simply waited out.
What surgery treats foot drop? +
Options include decompressing an entrapped peroneal nerve, repairing or grafting a damaged nerve, and nerve transfer to restore the ability to lift the foot. The right procedure depends on the cause, location, and time since onset. Tendon transfer is another option in selected cases.
How long do I have before surgery may not help? +
Like other nerve injuries, peroneal nerve problems are time-sensitive — muscles lose the ability to recover over months. Early evaluation gives the best chance of restoring function, so persistent foot drop should be assessed promptly.
