Foot & Ankle Tendon Repair: Indications and Procedures
Tendons are the cables of the foot and ankle — transmitting muscle force to bone to produce movement and stabilize joints. When tendons tear partially or completely, the mechanical system fails: the foot cannot push off effectively, cannot resist inversion forces, or loses arch support depending on which tendon is involved. Surgical repair restores the tendon’s continuity and function when conservative management cannot.
Achilles Tendon Repair
Complete Achilles tendon rupture — the sudden pop and inability to stand on tiptoe that typically occurs during explosive athletic activity — is one of podiatric surgery’s most significant procedures. The debate between operative and non-operative management has evolved: operative repair in active adults under 60 offers lower re-rupture rates (3–5% vs. 10–15% with functional bracing) and faster return to high-demand activity. Operative repair uses either open or minimally invasive techniques to reapproximate the torn tendon ends with high-strength sutures. Recovery involves progressive weight-bearing in a boot over 8 weeks, followed by physical therapy and gradual return to sport at 6–9 months.
Peroneal Tendon Repair and Reconstruction
The peroneal tendons (peroneus brevis and peroneus longus) run behind the lateral malleolus in a fibro-osseous groove, stabilizing the ankle against inversion. Peroneal tendon tears — longitudinal splits, most commonly in the peroneus brevis — are a frequently missed cause of chronic lateral ankle pain. MRI or high-resolution ultrasound confirms the tear pattern and guides surgical decision-making. Surgical options range from simple tenorrhaphy (suture repair of the split) to tenodesis to autograft reconstruction for massive tears. Superior peroneal retinaculum repair stabilizes subluxating tendons that snap over the fibula.
Posterior Tibial Tendon Reconstruction
In Stage II adult-acquired flatfoot (PTTD), the posterior tibial tendon has elongated and lost mechanical advantage. When orthotics and bracing fail to maintain arch position and function, surgical reconstruction — flexor digitorum longus tendon transfer to augment the failed posterior tibial tendon, combined with medializing calcaneal osteotomy to realign the heel and a spring ligament repair — restores arch function. This combined procedure is one of podiatric surgery’s most impactful interventions, preventing the progression to Stage III/IV flatfoot and arthrodesis.
Flexor Hallucis Longus (FHL) Tendon Pathology
The FHL tendon runs through a fibro-osseous tunnel behind the ankle (posterior ankle impingement area) and beneath the first metatarsal (sesamoid complex). FHL tenosynovitis in dancers (triggertoe) and FHL partial tears in athletes produce posterior or plantar first ray pain. Trigger hallux — triggering of the FHL through a stenotic tunnel — is managed by tendon sheath release. FHL tears are managed by repair or FHL-to-FDL tenodesis depending on tear location and extent.
Post-Surgical Rehabilitation
Tendon repair outcomes depend as much on rehabilitation as on surgical technique. Dr. Biernacki’s post-surgical protocols are evidence-based and individualized: early protected weight-bearing where tendon repair strength allows, progressive loading through physical therapy, and sport-specific functional testing before return to activity. Serial ultrasound evaluation monitors tendon healing and confirms structural integrity before loading parameters are advanced.

Dr. Tom Biernacki’s Recommendation
Tendon repair is technically demanding but also deeply satisfying. When a patient comes in unable to push off after an Achilles rupture, and 9 months later I watch them run a 5K — that’s what this work is about. The key is accurate diagnosis, the right procedure, and disciplined rehabilitation. All three have to go right.

Frequently Asked Questions
How long does foot tendon repair surgery take?
Foot and ankle tendon repair procedures vary in duration: isolated Achilles repair takes 45–90 minutes; peroneal tendon repair 60–90 minutes; PTT reconstruction with osteotomy 2–3 hours. All are outpatient procedures performed under regional anesthesia with mild sedation. Patients go home the same day.
Can a torn tendon heal without surgery?
Some partial tendon tears heal with conservative management — particularly peroneal tendon partial tears and Achilles tendon partial tears. Complete ruptures (Achilles) can be managed non-operatively with functional bracing but have higher re-rupture rates in active patients. The decision between operative and non-operative management depends on: degree of tear, patient activity level, age, and comorbidities.
What is the success rate of Achilles tendon surgery?
Achilles tendon repair surgery has excellent outcomes in appropriate candidates: 90–95% of patients return to pre-injury activity levels, with re-rupture rates of 3–5% — significantly lower than non-operative management in active individuals. Return to sport typically occurs at 6–9 months. Long-term tendon strength and function approach normal with appropriate rehabilitation.
