Walker Boots vs Plaster Casts: Cost-Effectiveness and Clinical Outcomes

For decades, plaster casts have been the default choice for immobilizing lower-limb injuries such as Achilles tendon ruptures and ankle fractures. However, growing clinical evidence suggests that functional walker boots offer a cost-effective alternative without compromising patient outcomes or safety.

So what does the latest research actually tell us? And how should this influence treatment decisions in modern orthopedic care?

Rethinking Immobilization: Why Cost-Effectiveness Matters

Healthcare systems are under increasing pressure to deliver high-quality outcomes while controlling costs. Immobilization strategies play a significant role in this equation, not just in terms of device cost, but also:

  • Time and resources required for application and removal
  • Follow-up appointments and unplanned hospital visits
  • Need for informal care and support
  • Speed of functional recovery and return to work

Multiple studies now indicate that walker boots consistently perform well across these areas, particularly when early weight-bearing protocols are used.

Achilles Tendon Rupture: Comparable Outcomes, Lower Overall Costs

One of the most robust datasets comes from the UKSTAR trial by Costa et al.1, a large multicenter randomized controlled study involving 527 patients across 39 NHS hospitals. The trial compared:

  • Traditional plaster casting (8 weeks, delayed weight bearing)
  • Functional walker boot (8 weeks, immediate weight bearing)

Key findings:

  • Total health and social care costs were slightly lower in the walker group (by approximately £103 per patient), although the difference was not statistically significant
  • No difference in functional outcome at 9 months, measured using the Achilles Tendon Total Rupture Score (ATRS)
  • No difference in re-rupture rates, confirming comparable safety profiles

In other words, functional bracing delivered equivalent clinical results at a lower or comparable cost, while enabling earlier mobilization.

Importantly, clinicians concluded that early weight-bearing in a walker boot can be considered a safe and cost-effective alternative to plaster casting.

Why Walker Boots May Support Better Recovery

The cost-utility advantage of walker boots is not purely financial, it is closely linked to how patients recover.

Evidence suggests improved functional recovery may be related to:

  • Greater comfort and convenience for patients2
  • Compatibility with early weight-bearing protocols1,3,4
  • Ability to remove the boot for controlled mobilization exercises1,5,6
  • Reduced reliance on informal carers7

These factors can translate into faster return to normal activity and work1,4,7, which has major societal and economic implications beyond direct healthcare costs.

Ankle Fractures: Strong Evidence Across Operative and Non-Operative Care

The evidence is equally compelling for ankle fractures. A UK multicenter randomized trial evaluated cast immobilization versus walker boots in 669 patients across 20 NHS trauma units.

Clinical outcomes:

  • No significant difference in functional outcomes at 4 months or 2 years8,9
  • Functional outcomes measured using the Olerud-Molander Ankle Score (OMAS) were equivalent8,9
  • Complication rates were similar between cast and walker groups8,9

Economic outcomes:

  • Cost-utility analysis showed that, from an NHS perspective, removable braces were cost-effective under commonly accepted willingness-to-pay thresholds10

The authors concluded that a removable walker boot is as effective and safe as a plaster cast, for both operative and non-operative ankle fracture management, and remains so in the long term.

Post-Operative Ankle Fractures: The Case for Early Weight Bearing

Recent studies have added another important dimension: timing of weight bearing.

Two major UK trials provide valuable insights:

1. Ankle Recovery Trial (ART)

  • Compared walker boots versus casts after ankle fracture surgery
  • Found the total treatment cost per patient was £676 lower in the walker group
  • Analysis included not only device cost, but also informal care and productivity losses

2. Weight-bearing in Ankle Fracture (WAX) Trial

  • Compared early vs delayed weight bearing post-operatively
  • Early weight bearing was associated with £722 lower mean societal costs, largely due to reduced work absence

Taken together, these findings suggest that early weight bearing in a walker boot may offer substantial cost savings compared to delayed weight bearing in a cast, without compromising safety or outcomes4,7.

What This Means for Clinical Practice

Across Achilles tendon rupture and ankle fracture management – both conservative and post-operative – the evidence consistently shows that walker boots:

  • Are at least as effective as plaster casts
  • Offer comparable safety profiles
  • Support earlier mobilization and weight bearing
  • Can deliver meaningful cost savings, especially when societal costs are considered

For clinicians and healthcare systems alike, this supports a shift toward functional immobilization strategies where clinically appropriate.

Conclusion: Walker Boots are Evidence-Based, Patient-Centered, Cost-Effective

Modern functional walkers allow clinicians to align clinical outcomes, patient experience, and economic efficiency. As the evidence base continues to grow, walker boots are increasingly positioned not as an alternative, but as a first-line option for many lower-limb injuries.

As always, individual patient factors and clinical judgement remain paramount, but the data clearly supports giving functional bracing serious consideration in contemporary orthopedic care.

The link between COVID-19 and heel pain

Since the COVID-19 pandemic began in 2020, the number of patients reporting heel pain has risen. The condition is now so common it has come to be known as “pandemic foot”. Is there really a link between COVID-19 and heel pain, and if so, what treatment options are available?

What is plantar fasciitis?

While “pandemic foot” might be a catchy name, the correct medical term is plantar heel pain, or plantar fasciitis. This condition presents as pain felt on the bottom of the foot around the heel and arch. It is an overuse condition often associated with runners, especially those over the age of 40.

Excessive pressure on the foot, along with a tight calf or Achilles tendon, can cause inflammation of the plantar fascia, the thick band of tissue on the bottom of the foot connecting the heel to the toes.

The pain is commonly felt during the first step, as well as during weight-bearing tasks, particularly after periods of rest.1 Patients often report the pain at its worst as they take their first steps of the day after getting out of bed. It typically decreases as the calf and Achilles tendon become looser during activity, only to return the following day after things have tightened up again during the night.

Does COVID-19 cause plantar fasciitis?

There is no current evidence to suggest there is a direct link between COVID-19 and heel pain. Instead, the rise in plantar fasciitis is more likely to be due to the changes in our daily lives the pandemic has brought about.

Gym attendances have declined since the beginning of the pandemic, with outdoor running and walking becoming more popular instead. More running and walking mean more stress on the plantar fascia, which, due to an increase in flexible working, can be exacerbated by more time spent walking around at home in bare feet, slippers, or flip-flops.

Without the additional support that a heeled shoe can provide, like those typically worn in office environments, the foot spends more time in a flat position, which, for extended periods, can put additional strain on the fascia. Add to this stiff muscles and tendons from running, and you have a recipe for plantar fasciitis. This is the indirect link between COVID-19 and heel pain.

How can heel pain be treated?

There are a number of conservative treatment options for plantar fasciitis. They range from relatively simple orthotics to more advanced rehabilitation devices.

Taping for heel pain

Physio tape (also known as kinesiology tape) like Chatt-Tape is elastic adhesive tape that can be applied to parts of the body to aid healing and recuperation of the soft tissue.2

Tape can be applied to the heel, ankle, and underside of the foot to release tension in the plantar fascia as well as stabilize it. A study by Tezel et al. (2020) showed that kinesiology tape provided pain relief and improved quality of life for patients with plantar fasciitis, as well as improved functionality.3

Chatt-Tape plantar fasciitis
Aircast AirHeel and Dorsal Night Splint

Bracing for heel pain

Plantar fasciitis can be relieved by wearing an orthotic during the night to help reduce the tightening of the calf muscles and Achilles tendon.4 One such device is Aircast’s Dorsal Night Splint; this product is worn while the patient sleeps, to maintain the position of the foot at 90°, thereby helping to stretch the calf and Achilles tendon.

Another type of foot orthosis for plantar fasciitis is a pneumatic ankle brace. Also from Aircast, the AirHeel is designed to treat plantar fasciitis, Achilles tendonitis, and heel pain. Using two interconnected aircells located under the foot arch and in the back of the heel, the brace applies pulsating compression with every step to help reduce swelling and discomfort and enhance circulation.

Kavros’s 2005 study showed that patients with higher plantar fasciitis pain experience faster relief with the Airheel than with a shoe insert.5

Shock wave therapy for heel pain

Shock wave therapy is an electronic modality that uses acoustic waves to stimulate the body on a cellular level for healing purposes. Generally divided into focused shock wave (F-SW) and radial pressure wave (RPW) therapy, shock wave therapy has been shown to be a clinically proven treatment option for plantar fasciitis, especially when treatments like taping have not been successful.1

In a 2022 study by Wheeler et al., RPW treatment provided significant improvement of pain and function in patients with chronic plantar fasciopathy.6

Intelect 2 RPW
LightForce laser therapy

High power laser therapy for heel pain

High power laser therapy, like that offered by LightForce, uses the energy of focused light to trigger the body’s natural healing processes, thereby speeding recovery.

Ordahan et al.’s 2018 study demonstrated that high power laser therapy provided improvement of pain and function in patients with plantar fasciitis.7

Combining laser therapy with shock wave therapy has shown to be even more effective.8
