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.

What Is Ankle Fusion (Arthrodesis)?

Ankle fusion (tibiotalar arthrodesis) is a surgical procedure that eliminates the arthritic ankle joint by fusing the tibia (shinbone) to the talus (ankle bone) with screws, plates, or a nail. The cartilage surfaces are removed and the bones are held in rigid contact until they grow together as one—eliminating the painful joint motion that is the source of arthritic pain. The result is a stable, pain-free ankle that no longer moves, with the functional loss of that motion compensated over time by adjacent foot joints.

Ankle fusion is the most durable surgical option for end-stage ankle arthritis—with 85–95% good-to-excellent pain relief and lower long-term revision rates than total ankle replacement. It is the preferred surgical approach in younger, active, higher-demand patients; those with significant deformity or poor bone quality; and those with prior infection or failed ankle replacement. Unlike replacement, fusion eliminates ankle motion permanently—which requires careful consideration but does not prevent most activities of daily living or moderate recreational activity.

The Surgery

Ankle fusion is performed under general or spinal anesthesia. The most common approaches are the posterior approach (using a retrograde intramedullary nail inserted through the heel), the lateral approach (plates and screws applied through the outer ankle), and the arthroscopic approach (for less deformed joints, allowing smaller incisions and potentially faster recovery). The articular cartilage is removed from both the tibial plafond and the talar dome, and the surfaces are prepared to raw bone contact. Bone graft (autograft, allograft, or synthetic) may be added to improve fusion rates. Fixation is rigid to allow bone healing across the joint.

Recovery Timeline

Weeks 0–2: Elevation and Rest

The first two weeks are focused on wound healing and swelling control. The foot is elevated above heart level as much as possible—this is critical for minimizing swelling, which can cause wound healing problems and pain. A splint or non-weight-bearing cast is applied. Most patients use crutches, a knee scooter, or a wheelchair to stay completely non-weight-bearing. Pain is managed with prescription pain medication, transitioning to over-the-counter analgesics as healing progresses. Swelling, bruising, and some numbness around the incision are normal.

Weeks 2–6: Protected Healing

The splint is converted to a cast or rigid boot at the 2-week wound check. Non-weight-bearing continues through 6 weeks to allow early bone healing at the fusion site. Imaging (X-rays) at 6 weeks assesses early callus formation and hardware position. Keeping the leg elevated whenever sitting or lying down remains important throughout this phase for swelling management.

Weeks 6–12: Beginning to Walk

Progressive weight-bearing in a walking boot begins around 6–8 weeks when X-rays show adequate early fusion. Weight-bearing starts at 25% of body weight and increases over 4–6 weeks to full weight-bearing. Physical therapy begins during this phase—focused on gait training, strengthening the hip and knee muscles compensating for the fused ankle, and reducing swelling. The walking boot is typically worn until 10–12 weeks post-surgery.

Months 3–6: Transition to Normal Activity

Transition to regular footwear (with a rocker-sole shoe to support push-off mechanics) occurs around 10–12 weeks when fusion is confirmed on CT scan. Walking without assistive devices, driving, and sedentary work return at 3 months for most patients. Swelling continues improving over months 3–6. Lower-impact activities (cycling, swimming, light hiking on flat terrain) are progressively resumed. Return to manual labor or construction work typically occurs at 4–6 months.

Months 6–12: Full Recovery

Most patients reach maximum functional improvement by 12 months, though some continue improving through 18 months. The body adapts to the fused ankle by recruiting motion at the subtalar joint (below the talus), the midtarsal joints, and the forefoot—providing a surprisingly functional gait. Patients who undergo successful ankle fusion regularly report that they “forgot” the ankle was fused after full recovery, as the compensatory motion becomes natural. Shoe wear adapts to accommodative footwear with rocker-sole modifications.

Life After Ankle Fusion

Most patients with successful ankle fusion can walk unlimited distances, stand for extended periods, climb stairs normally, hike on flat-to-moderate terrain, swim, cycle, and participate in low-impact recreational sports. Activities involving jumping, running, or significant ankle dorsiflexion (such as deep squats) are more challenging. Long-term, the increased mechanical demand on the subtalar and midfoot joints from ankle fusion may accelerate arthritis in those joints—a phenomenon called adjacent joint arthritis that may require treatment decades later. The risk appears lower in patients fused in optimal alignment.

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.
