Lisfranc Injury Surgery: When & What to Expect

Lisfranc injuries span a spectrum from stable ligamentous sprains to severe fracture-dislocations of the tarsometatarsal joint complex. The critical decision point is instability — stable Lisfranc injuries can be treated non-operatively; unstable injuries require surgical fixation because even 2 mm of displacement left untreated leads to progressive midfoot arthritis and permanent functional loss.

Lisfranc Injury Classification and Treatment Decision

Type	Description	Stability Test	Treatment
Stable ligamentous sprain	Lisfranc ligament injury without diastasis; less than 2 mm gap on stress X-ray	Stress X-ray (abduction/pronation force): no gapping	Non-weight-bearing 6 weeks; progressive return 3-4 months
Purely ligamentous — unstable	Lisfranc ligament complete tear; 2+ mm diastasis on stress views	Stress X-ray: gapping at 1st-2nd intermetatarsal space	Surgery: ORIF vs primary arthrodesis (debate ongoing)
Fracture-dislocation (Quenu-Kuss homolateral)	All 5 rays displaced in same direction	Obvious on standard X-ray	Surgical ORIF or primary arthrodesis
Fracture-dislocation (divergent)	Medial and lateral rays displaced in opposite directions	Obvious on standard X-ray; high-energy mechanism	Urgent surgical fixation; evaluate vascular status
Partial (isolated)	One or two rays involved; partial dislocation	CT scan best for classification	Surgical if unstable; non-operative if stable

Surgical Options: ORIF vs Primary Arthrodesis

Factor	ORIF (Open Reduction Internal Fixation)	Primary Arthrodesis (Fusion)
Principle	Reduce and hold with screws/plates; hardware removed at 4-6 months	Fuse 1st-3rd TMT joints; permanent fixation
Best for	Fracture-dislocations; younger athletes; joint cartilage preserved	Purely ligamentous unstable injuries; older patients; higher arthritis risk
Return to sport	9-12 months for full return; hardware removal adds recovery step	12-18 months; no hardware removal needed
Late arthritis rate	25-50% develop TMT arthritis within 10 years	Eliminates arthritis at fused joints; adjacent joints remain
Evidence	Comparable outcomes in fracture-dislocation types	Superior outcomes for purely ligamentous injuries in multiple RCTs

Weight-bearing CT scan is the gold standard for Lisfranc injury classification and surgical planning — it reveals subtle diastasis and bony involvement invisible on standard X-rays. MRI identifies purely ligamentous injuries before stress X-rays become diagnostic. Any midfoot sprain that fails to improve in 2 weeks warrants advanced imaging to exclude occult Lisfranc injury.

At Balance Foot & Ankle in Howell and Bloomfield Township, we evaluate midfoot injuries with weight-bearing X-rays, stress views, and CT when Lisfranc injury is suspected. Call (810) 206-1402.

What Lisfranc Surgery Actually Involves

Lisfranc surgery realigns and stabilizes the tarsometatarsal joint complex so the arch can bear weight without collapsing. The two main operations are open reduction and internal fixation (ORIF) and primary arthrodesis (fusion). Both are typically performed under general anesthesia with a regional nerve block, take roughly 1–2 hours, and most patients go home the same day.

ORIF (open reduction and internal fixation)

Through one or two small incisions on the top of the foot, the surgeon restores each displaced joint to its exact anatomic position and holds it with screws, plates, or a combination. ORIF preserves the joints themselves, which is why it is favored for fracture-dislocations where the joint surfaces are repairable. Screws crossing the Lisfranc ligament are often removed at 4–6 months once the ligament has healed.

Primary arthrodesis (fusion)

Instead of repairing the unstable joints, the surgeon removes the damaged cartilage and fuses the involved tarsometatarsal joints in their corrected position. Multiple randomized trials show better outcomes with primary fusion for purely ligamentous injuries, because ligament-only repairs have high rates of late arthritis and hardware failure. Fusing the first through third tarsometatarsal joints sacrifices very little useful motion — these joints are naturally rigid.

Recovery Timeline After Lisfranc Surgery

• Weeks 0–2: splint, strict elevation, no weight on the foot. Sutures out around 2 weeks.
• Weeks 2–8: cast or boot, non-weight-bearing (typically 6–8 weeks total) with a knee scooter or crutches.
• Weeks 8–14: progressive weight-bearing in the boot over 4–6 weeks as X-rays confirm healing.
• Months 3–6: supportive shoes and physical therapy for strength and gait; possible hardware removal after ORIF.
• Months 9–12: return to running and sport for most ORIF patients; fusion patients may need 12–18 months for full activity.

The single biggest recovery variable is respecting the non-weight-bearing window. Bearing weight early — even once — can shift the fixation, and a midfoot that heals 2 mm out of position loses the arch mechanics the surgery was done to restore. Our full Lisfranc recovery guide covers each phase in detail.

Risks and Complications

• Post-traumatic arthritis — the most common late problem after ORIF (25–50% within 10 years); managed with orthotics, and with fusion if disabling. Fusion eliminates arthritis at the fused joints.
• Hardware irritation — screws and plates sit directly under thin skin on the top of the foot; removal is a minor secondary procedure.
• Nonunion — fused joints occasionally fail to knit, more often in smokers and patients with diabetes; revision fusion may be needed.
• Infection, nerve irritation, and blood clots — uncommon with outpatient foot surgery, but risk rises with smoking, uncontrolled blood sugar, and early weight-bearing.

Smoking cessation and tight glucose control before surgery measurably improve healing — we screen for both at the pre-operative visit.

How We Choose Between ORIF and Fusion

The decision comes down to injury pattern. Fracture-dislocations with repairable joint surfaces usually get ORIF, since outcomes are comparable and the joints are preserved. Purely ligamentous unstable injuries increasingly get primary fusion, supported by randomized trials showing fewer reoperations and better function. Stable injuries — under 2 mm of gapping on stress X-rays — do not need surgery at all; see our guide to treating a stable Lisfranc sprain without surgery.

Frequently Asked Questions

How long am I off my foot after Lisfranc surgery?

Plan on 6–8 weeks completely non-weight-bearing, then 4–6 weeks of protected walking in a boot. Most desk workers return to work within 2–3 weeks with the foot elevated; standing occupations take 3–4 months.

Do the screws have to come out?

After ORIF, screws that cross the Lisfranc ligament are commonly removed at 4–6 months. Fusion hardware stays in unless it irritates.

Can a Lisfranc injury heal without surgery?

Stable injuries — no displacement on weight-bearing and stress X-rays — heal reliably with 6 weeks of non-weight-bearing immobilization. Any instability is a surgical problem: the midfoot cannot hold its position under body weight once the ligament is incompetent.

What is the long-term outlook?

With anatomic reduction, most patients return to full activity, including sport. Outcomes track directly with how accurately the joints were realigned and how faithfully the recovery protocol was followed. Symptoms, diagnosis and every stage of recovery are covered in our Lisfranc injury recovery guide.
