| Indication | Primary Goal | Nerve Status Required | Ankle Status | Contraindication |
|---|---|---|---|---|
| Peroneal Nerve Palsy / Foot Drop | Restore active dorsiflexion; reduce AFO dependence | Intact motor unit in PTT (L4–S1); EMG confirmation | Supple ankle; no fixed equinus | Fixed equinus contracture >20° (requires prior Achilles lengthening) |
| Charcot-Marie-Tooth (CMT) | Restore dorsiflexion; stabilize cavovarus deformity | PTT must be innervated; split vs full transfer based on foot type | Flexible cavovarus; no fixed ankle equinus | Rigid fixed deformity (needs osteotomy first); absent PTT innervation |
| L4–L5 Radiculopathy (permanent) | Functional dorsiflexion after failed nerve recovery | PTT ≥4/5 strength; viable tendon | Passive ankle dorsiflexion ≥5° | Active nerve recovery in progress (<12–18 months post-injury) |
| Stroke / CVA (upper motor neuron) | Adjunct to spasticity management; selected cases | PTT innervated (lower motor neuron spared) | Fixed equinus must be addressed first | Spastic PTT (contributes to equinovarus) — split transfer preferred |
| Transfer Type | Technique | Indication | Outcome | Recovery |
|---|---|---|---|---|
| Full PTT Transfer (Bridle Procedure) | Reroute entire PTT through interosseous membrane to dorsal foot (EHL or 3rd cuneiform) | Peroneal nerve palsy; foot drop; no spasticity; balanced transfer desired | 85–90% achieve active dorsiflexion; 80% reduce/eliminate AFO dependence | 6–8 weeks NWB cast; 3–6 months PT; full function 6–9 months |
| Split PTT Transfer | Split tendon; medial half left at navicular, lateral half transferred anteriorly | CMT with mild equinovarus; spastic equinovarus (CVA); balanced foot desired | 75–85% correction; preserves medial column stability | Same as full transfer; slightly less PT for retraining |

Quick Answer:
Quick Answer: Tibialis posterior tendon transfer (TPTT) is a reconstructive procedure that redirects the tibialis posterior tendon — normally a powerful plantar flexor and invertor — to function as a dorsiflexor when the anterior muscles are paralyzed (foot drop). The classic indication: foot drop from peroneal nerve palsy, CMT (Charcot-Marie-Tooth), or other peripheral neuropathy causing inability to lift the forefoot. The tendon is rerouted through the interosseous membrane and attached to the dorsum of the foot (extensor tendon insertion or cuneiform). Result: active dorsiflexion replaces the paralyzed anterior tibialis. Requires intact tibialis posterior muscle strength (4+/5 minimum) and supple ankle and subtalar joints. Combined with procedures as needed for associated equinus or cavovarus deformity.
Tibialis posterior tendon transfer (TPTT) is one of the most significant procedures in foot and ankle surgery — converting a powerful plantar flexor muscle into an active dorsiflexor to restore foot clearance and functional gait in patients with foot drop. When peroneal nerve palsy, Charcot-Marie-Tooth disease, or other neurological conditions eliminate anterior tibialis function, the patient cannot lift the forefoot — creating a steppage gait, tripping risk, and the need for ankle-foot orthoses (AFO). At Balance Foot & Ankle PLLC, Dr. Tom Biernacki performs tibialis posterior tendon transfer as part of comprehensive neuromuscular foot reconstruction.
Indications for Tibialis Posterior Tendon Transfer
Foot drop from peroneal nerve palsy: The most common indication — peroneal nerve injury from fibula fracture, knee dislocation, prolonged compression, or idiopathic causes eliminates anterior tibialis, extensor hallucis longus, and extensor digitorum longus function. Foot drop that fails to recover at 12-18 months despite conservative management is appropriately treated with TPTT. Charcot-Marie-Tooth (CMT) disease: Progressive peroneal weakness produces foot drop and cavovarus deformity — TPTT combined with plantar fascia release and calcaneus osteotomy corrects the deformity. Stroke and upper motor neuron lesions: Select cases of spastic foot drop may benefit from surgical rebalancing. Prerequisites: Tibialis posterior muscle strength 4+/5 minimum (assessed pre-operatively), supple ankle dorsiflexion (if equinus present, Achilles lengthening is performed simultaneously), and supple subtalar joint. Fixed rigid deformity requires bony correction before or concurrent with tendon transfer.
Surgical Technique
TPTT via the interosseous membrane route (anterior transfer): medial incision harvests the tibialis posterior tendon from its insertion on the navicular; the tendon is then passed through a window created in the interosseous membrane between the tibia and fibula, emerging anteriorly. The tendon is routed subcutaneously and attached to the dorsum of the foot — typically the cuneiform or extensor tendon apparatus — with a tenodesis screw or bone anchor under appropriate tension. The foot is positioned at neutral or slight dorsiflexion during tensioning. Simultaneous procedures performed as needed: Achilles tendon lengthening for equinus contracture, plantar fascia release for cavus, calcaneus or first metatarsal osteotomy for cavovarus. Post-operative: non-weight-bearing 6 weeks in below-knee cast, progressive weight-bearing, intensive physical therapy for tendon re-education and transfer motor learning.
Rehabilitation and Outcomes
Tibialis posterior tendon transfer rehabilitation requires intensive physical therapy focused on transfer motor learning — the brain must learn to activate the tibialis posterior (previously an invertor and plantarflexor) to produce dorsiflexion. Biofeedback and EMG-guided therapy accelerates this re-education. Most patients achieve meaningful active dorsiflexion within 3-6 months, with continued improvement for 12-18 months. Long-term outcomes: elimination of foot drop AFO dependence in 70-80% of appropriately selected patients, significantly improved gait mechanics and fall risk reduction, and sustained function over the long term.

✅ Pros / Benefits
- Eliminates foot drop AFO dependence in 70-80% of appropriately selected patients
- Restores active dorsiflexion and dramatically improves gait mechanics and safety
- Simultaneous correction of equinus and cavovarus deformity in a single surgical episode
- Durable long-term results in properly selected patients with adequate muscle strength
❌ Cons / Risks
- Requires intensive physical therapy for transfer motor re-education — months of committed rehabilitation
- Patients with weak tibialis posterior (less than 4+/5) are not candidates — the transfer will be inadequate
- Transfer tension must be set precisely — overtightening produces equinus, undertightening produces inadequate lift
Dr. Tom Biernacki’s Recommendation
Tibialis posterior tendon transfer is one of the most rewarding procedures I perform — watching a patient who has been steppage-gait walking with an AFO for years achieve independent foot clearance is notable. The key is patient selection: the tibialis posterior must be strong enough to work as a transfer, the joints must be supple enough for the new motion to be useful, and the patient must be committed to the rehabilitation. When those conditions are met, the outcomes are outstanding.

Frequently Asked Questions
What is foot drop and how is it treated?
Foot drop is the inability to lift the forefoot during walking — caused by weakness or paralysis of the anterior tibialis and toe extensor muscles, most commonly from peroneal nerve injury, CMT disease, stroke, or lumbar disc herniation. Non-surgical treatment: ankle-foot orthosis (AFO) to hold the foot at 90 degrees during walking. Surgical treatment: tibialis posterior tendon transfer when conservative management fails or is inappropriate. TPTT converts the powerful plantar flexor muscle into an active dorsiflexor, potentially eliminating AFO dependence. Recovery of peroneal nerve function is observed for 12-18 months before surgical tendon transfer is performed for most causes.
How long does recovery from tibialis posterior tendon transfer take?
Recovery from TPTT follows this timeline: 0-6 weeks non-weight-bearing in a below-knee cast, 6-12 weeks progressive weight-bearing with physical therapy, 3-6 months active dorsiflexion development through transfer motor re-education, 6-12 months full functional improvement. Patients continue to improve for 12-18 months as the nervous system completes transfer motor learning. Return to work timing varies by occupation — sedentary work at 3-4 months, physical labor at 6-12 months.
Am I a candidate for tibialis posterior tendon transfer?
Candidates for TPTT must meet specific criteria: tibialis posterior muscle strength of 4+/5 or greater on manual muscle testing, supple (flexible) ankle and subtalar joints without fixed equinus or rigid deformity, foot drop from an appropriate cause (peroneal nerve palsy, CMT, etc.), and failure or unsuitability of conservative AFO management. Patients with inadequate muscle strength, rigid deformity requiring bony correction only, or upper motor neuron spasticity may require different approaches. Evaluation at Balance Foot & Ankle includes complete neuromuscular assessment to determine candidacy.
What is the difference between a tendon transfer and a tendon repair?
A tendon repair reconnects a torn tendon back to its original attachment point — restoring its original function. A tendon transfer harvests a functioning tendon from its original insertion and reattaches it to a new location, redirecting the muscle’s force to perform a different motion. Tibialis posterior tendon transfer takes a tendon that normally plantarflexes and inverts the foot and routes it to the dorsum where it instead dorsiflexes the foot. The muscle retains its contractile capacity but now produces the opposite motion — requiring intensive physical therapy for motor re-education.

When should I see a podiatrist?
If symptoms persist past 2 weeks, affect your normal activity, or are accompanied by red-flag symptoms (warmth, redness, swelling, inability to bear weight).
What does treatment cost?
Most diagnostic visits and conservative treatments are covered by Medicare and major insurers. Out-of-pocket costs vary by your specific plan.
How quickly can I get an appointment?
Most non-urgent cases see us within 5 business days. Urgent cases (sudden pain, possible fracture) typically same or next business day.
Foot pain typically responds best to early podiatrist evaluation, conservative treatments such as supportive footwear and targeted physical therapy, and—when needed—custom orthotics or in-office procedures. Most patients see meaningful improvement within 4-6 weeks of starting a structured treatment plan. Schedule an evaluation at our Howell or Bloomfield Hills office for a clinical assessment.
What is Foot pain?
Foot pain is a common foot/ankle condition that affects mobility and quality of life. Understanding the underlying cause is the first step in successful treatment. Our podiatrists at Balance Foot & Ankle perform a hands-on biomechanical exam, review your activity history, and use diagnostic imaging when appropriate to identify the root cause—not just treat the symptom. Many patients have been told to “rest and ice” without a deeper diagnostic workup; our approach is different.
Symptoms and warning signs
Common signs of foot pain include pain that worsens with activity, morning stiffness, swelling, tenderness when palpated, and difficulty bearing weight. If you experience sudden severe pain, inability to walk, visible deformity, numbness or color change, contact our office the same day or visit urgent care—these can signal a more serious injury such as a fracture, tendon rupture, or vascular compromise. Diabetics with any foot wound should seek same-day care.
Conservative treatment options
Most cases of foot pain respond to non-surgical care: structured rest, supportive footwear changes, custom orthotics, targeted stretching and strengthening protocols, anti-inflammatory medications when medically appropriate, and in-office procedures such as ultrasound-guided injections. We also offer advanced therapies including MLS laser therapy, EPAT/shockwave, regenerative injections, and image-guided procedures. Treatment is sequenced from least invasive to most invasive, and we explain the rationale at every step.
When is surgery considered?
Surgery is reserved for cases that fail 3-6 months of well-structured conservative care, when there is structural pathology (severe deformity, complete tear, advanced arthritis), or when imaging shows damage that will not heal without intervention. Our surgeons have performed 3,000+ foot and ankle procedures and prioritize minimally-invasive techniques whenever appropriate. We discuss recovery timelines, return-to-activity milestones, and realistic outcome expectations before any procedure is scheduled.
Recovery timeline and prevention
Recovery from foot pain varies based on severity and chosen treatment path. Conservative cases often improve within 4-8 weeks with consistent adherence to the protocol. Post-procedural recovery may range from a few days (in-office procedures) to several months (reconstructive surgery). Long-term prevention involves footwear assessment, activity modification, structured strengthening, and regular check-ins with your podiatrist if you have a history of recurrence. We provide written home-exercise plans and digital follow-up support.
