Quick answer: Posterior Tibial Tendon Pain has multiple potential causes including mechanical, neurological, vascular, and inflammatory. The patterns we see most often are overuse, poorly-fitted shoes, and biomechanical imbalance. Red flags requiring urgent evaluation: warmth/redness (infection), inability to bear weight (fracture), and unilateral swelling without injury (DVT). Call (810) 206-1402.
The most important clinical decision with Posterior Tibial Tendon Pain isn’t which treatment to start with — it’s identifying the correct subtype. That changes everything. Call (810) 206-1402.

What Is the Posterior Tibial Tendon?
![Posterior Tibial Tendonitis Treatment [Fix Inside Of The Ankle Pain!] | Balance Foot Ankle](https://www.michiganfootdoctors.com/uploads/2021/04/posterior-tibial-tendonitis-treatment-fix-inside-of-the-ankle-pain-1.avif)
The posterior tibial tendon is the primary dynamic support of the medial longitudinal arch—the inner arch of the foot. It runs behind the medial malleolus (inner ankle bone) and attaches to multiple bones of the midfoot, where it acts to invert the foot, plantarflex the ankle, and lock the midfoot joints to allow a rigid push-off during walking. When this tendon degenerates, tears, or fails, the arch progressively collapses—a condition called posterior tibial tendon dysfunction (PTTD), the most common cause of adult-acquired flatfoot.
Pain along the posterior tibial tendon—running from behind the inner ankle to the bottom of the foot along the arch—is the hallmark symptom of PTTD in its early stages. This is a critical window: early-stage PTTD (Stage I, tendinitis without deformity) responds well to conservative treatment, while late-stage disease requires complex reconstruction. Recognizing and treating PTTD before significant arch collapse occurs is the most important principle in management.
Symptoms: What PTTD Feels Like
The classic presentation is a middle-aged to older adult—most commonly a woman—who notices pain and swelling along the inner ankle and arch that develops gradually over months. The pain is typically worse with activity (prolonged standing, walking, climbing stairs) and better with rest. As the disease progresses, patients notice that their arch seems to be flattening and that the affected foot points outward more than the other when walking. The single-heel-rise test—attempting to rise on tiptoe on the affected foot alone—becomes difficult or impossible as tendon function declines. In severe PTTD, patients develop progressive flatfoot deformity even after the acute tendon pain has resolved.
Diagnosis
Clinical examination is the primary diagnostic tool: tenderness directly along the posterior tibial tendon behind the medial malleolus and along its course to the navicular bone, weakness with resisted foot inversion, and inability to perform single-heel rise on the affected foot. Weight-bearing X-rays demonstrate arch collapse (decreased calcaneal pitch, talonavicular coverage angle) when deformity is present. MRI is the gold standard for characterizing tendon pathology—showing peritendinitis, tendinosis, partial tear, or complete rupture—and directly guides surgical planning.
Treatment
Stage I: Tendinitis Without Deformity
Early PTTD without arch collapse responds well to anti-inflammatory treatment (NSAIDs, ice) and immobilization in a CAM boot for 4–6 weeks to rest the tendon. A custom orthotic with aggressive medial arch support and heel valgus posting is then prescribed for long-term tendon support. Physical therapy for progressive posterior tibial tendon and calf strengthening is an essential component—eccentric strengthening exercises for the posterior tibial tendon are the most effective physical therapy intervention. Most Stage I PTTD patients improve substantially with conservative treatment.
Stage II: Flexible Flatfoot
When arch collapse has developed but remains flexible (correctable passively), conservative treatment with an Arizona brace (a custom ankle-foot orthosis providing rigid arch support) may stabilize the deformity. When conservative treatment fails, surgical reconstruction combines posterior tibial tendon debridement or FDL tendon transfer, medial calcaneal osteotomy (shifting the heel inward), and sometimes lateral column lengthening—reconstructing the arch anatomy.

Frequently Asked Questions
How do I know if my posterior tibial tendon is torn?
You cannot reliably determine tendon tear severity from symptoms alone—MRI is required for definitive characterization. Clinically, a complete posterior tibial tendon tear is suggested by: inability to perform a single-heel rise on the affected foot, progressive flatfoot deformity that has developed relatively quickly, and very significant tendon tenderness. Partial tears may present with tendinitis-like symptoms but more persistent disability than expected for simple inflammation. In clinical practice, the most important distinction is whether the deformity (if present) is flexible or rigid—which determines treatment options—rather than the exact degree of tendon tearing. MRI showing complete tendon rupture without viable tissue changes the surgical approach from tendon debridement/reinforcement to FDL tendon transfer reconstruction.
What exercises help posterior tibial tendon pain?
Physical therapy for PTTD focuses on posterior tibial tendon strengthening, calf flexibility, and arch support exercises. Key exercises: seated foot inversion against resistance (resistance band or towel around the ball of the foot, resisting inversion), single-leg heel raises (building to 25–30 reps, which is the functional strength target), eccentric heel drops on a step for Achilles/calf flexibility, and intrinsic foot strengthening (towel scrunches, marble pickups). These exercises must be performed consistently over months—occasional exercise provides minimal benefit for tendon rehabilitation. The exercises are most effective in Stage I PTTD before arch collapse—once significant flatfoot deformity is present, strengthening alone is insufficient and orthotic support or surgery is needed.
Can posterior tibial tendon dysfunction be reversed?
Stage I PTTD—tendinitis without deformity—can fully resolve with appropriate treatment, allowing return to normal function without long-term orthotic dependence in some patients. Stage II PTTD (flexible flatfoot) can be stabilized with orthotics to prevent further progression, but the existing arch collapse typically does not fully reverse. Surgical reconstruction can correct the flatfoot deformity in Stage II, restoring more normal alignment. Stage III (rigid flatfoot) cannot be corrected without fusion surgery. The window of opportunity for reversal or conservative control is early in the disease—this is why any progressive arch flattening or inner ankle pain in an adult should be evaluated promptly rather than watched indefinitely without assessment.

Frequently Asked Questions
When should I see a podiatrist?
See a podiatrist if: foot or ankle pain has lasted more than 2–4 weeks without improvement, you’re changing your gait to avoid pain, you have an open wound or sore that isn’t healing, you notice nail discoloration or thickening, you have diabetes and any foot concern, or pain is severe enough to wake you at night. Most foot conditions are easier and cheaper to treat early — what starts as a minor issue can become a surgical problem with months of delay.
What is the difference between a podiatrist and an orthopedic surgeon?
Podiatrists (DPM — Doctor of Podiatric Medicine) specialize exclusively in the foot, ankle, and lower leg. Orthopedic surgeons (MD/DO) have broader musculoskeletal training but variable foot/ankle subspecialization. For foot and ankle-specific problems, a podiatrist often has more focused training and experience. For injuries involving the leg above the ankle, complex pediatric cases, or multi-level reconstruction, orthopedic consultation may be appropriate. We frequently co-manage patients with orthopedic colleagues.
How do I know if my foot pain is serious?
Signs that warrant same-day or next-day evaluation: severe pain that appeared suddenly without clear cause, swelling, redness, and warmth that appeared suddenly (possible gout, infection, or Charcot fracture), an open wound that looks infected (redness spreading, pus, warmth), inability to bear weight, or any foot problem in a diabetic patient. Pain that’s been present for weeks and is stable is important but not an emergency — schedule within 1–2 weeks.
Can foot problems cause back and knee pain?
Yes — this is a kinetic chain effect. Abnormal foot mechanics (overpronation, supination, leg length discrepancy) cause compensatory changes in knee, hip, and lumbar alignment. Roughly 30% of patients presenting to our clinic with knee pain have a treatable foot-level biomechanical cause. Correcting foot mechanics with orthotics or appropriate footwear often provides significant knee and back relief. If you have chronic knee or back pain and haven’t had your foot mechanics evaluated, it’s worth a consult.
Are orthotics worth it?
For the right conditions, yes — custom orthotics are among the most cost-effective interventions in podiatry. They’re most effective for: plantar fasciitis, flat feet with secondary knee/back pain, leg length discrepancy, metatarsalgia, posterior tibial tendon dysfunction, and diabetic foot pressure management. Quality OTC orthotics ($35–60) resolve symptoms for 60% of patients with mild-to-moderate conditions. Custom orthotics are appropriate when OTC options have failed or when the biomechanical problem is complex. We cast custom orthotics in-office.
How do I choose the right running shoes?
Start with your foot type (flat, neutral, high arch) and running pattern (overpronator, neutral, supinator). Flat feet and overpronators do best in stability or motion-control shoes. Neutral feet do well in neutral-cushioned shoes. High arches need maximum cushioning with flexible soles. Always buy running shoes at the end of the day (foot swelling peaks then), get properly fitted by a specialist, and replace every 300–500 miles. If you’ve been injured repeatedly, a gait analysis can identify the mechanical flaw driving your injury pattern.
What is the difference between a sprain and a fracture?
A sprain is a ligament injury (the tissue connecting bones); a fracture is a break in the bone itself. Both can occur with the same trauma (ankle roll, fall). The old test — ‘if you can walk, it’s not broken’ — is wrong; many fractures are initially weight-bearable. Key differences: a fracture typically produces localized bone tenderness along the bone itself, while a sprain is tender over the ligament. X-ray is the standard to differentiate. High-grade sprains without proper treatment can be as disabling as fractures.
How do I prevent foot and ankle injuries?
The four most impactful prevention strategies: (1) Supportive, appropriately fitted footwear for your foot type and activity. (2) Gradual activity progression — the 10% rule (never increase weekly mileage or intensity by more than 10%). (3) Regular calf and ankle mobility work. (4) Strengthening the posterior tibial tendon, peroneals, and intrinsic foot muscles. Most overuse injuries are preventable; most acute injuries are not — but ankle sprain recurrence (60–70% without rehab) is prevented by balance and proprioception training.
