Free Swinging KAFOs at Orthotics Plus
A Free Swinging KAFO is a type of Knee-Ankle-Foot Orthosis designed to provide stability to the knee in the medial-lateral (ML) plane—side-to-side stability— and against hyperextension without resistance during the swing or stance phases of gait.
Think of it as a very strong and supportive frame around your knee with a hinge; it allows free movement in one plane (front to back) while stabilising the knee in the side-to-side direction and against hyperextension. This type of KAFO is particularly suited for individuals who only require support to prevent the knee from hyperextending or moving side-to-side and those with lower limb weakness but good hip strength.
These helpful devices are available for prescription and fitting through Orthotics Plus.
Types of Free Swinging KAFO Available
- Posterior Offset- extra stability
- No posterior offset- less stable but smaller
- Extension dampener componentry- quieter
Who Would Benefit from a Free Swinging KAFO?
Patients who benefit from a Free Swinging KAFO often have neurological conditions such as polio or stroke, where the muscles controlling knee stability are compromised or injuries where integral structures are damaged.
Why?
Conditions can weaken the muscles and ligaments that stabilise the knee, leading to instability in the mediolateral (ML) plane. This instability can cause the knee to buckle inward or outward or hyperextend, increasing the risk of falls and damage to the knee structure. A free-swinging KAFO provides the needed support by limiting unwanted ML movement and hyperextension while allowing normal forward motion.
Free swinging KAFOs can also be used for those with weak knee extensors to allow them to lock the knee backwards for stability without causing damage over the longer term.
It may also be used in cases of severe ligament damage or post-surgical conditions that affect knee stability. While these KAFOs are not typically electronic, they provide crucial mechanical support for those who need it.
Construction and Mechanism
The construction of a Free Swinging KAFO is straightforward but effective.
The orthosis is comprised of metal bars and joints positioned on either side of the knee, extending down to the foot and up to the thigh. These metal bars are connected to the leg through plastic or carbon fibre shells, with straps to keep everything securely in place.
The joints are designed to facilitate movement in sagittal plane (front to back), preventing any unwanted side-to-side movement.
Manufacturers and Cost Considerations
Free Swinging KAFOs are all custom made by Orthotics Plus using high end medical componentry supplied by manufacturers such as Fior & Gentz, Ottobock, and Becker.
These devices are custom-fitted to the patient, with various options available depending on the required level of stability. Compared to stance control KAFOs, Free Swinging KAFOs are significantly lower cost.
However, the specific cost will depend on the components used and the complexity of the device. These costs are advised early in the process, so the client has choice and control.
Patient Considerations: Weight, Comfort, and Appearance
One of the main considerations with Free Swinging KAFOs is their weight.
These devices are generally heavier than standard knee braces due to the metal bars and joints required for structural support. However, advancements in materials, such as carbon fibre, have helped reduce the weight while maintaining strength.
Patients may also be concerned about the bulkiness and appearance of the device, but these factors are often outweighed by the benefits of increased stability and mobility.
We can arrange trial and demonstration devices in certain situations for those seeking reassurance.
Compatibility with other Mobility Aids
Most patients who use KAFOs use other mobility aids, such as walking sticks, crutches, or Nordic walking poles.
These aids may help compensate for any additional weight or balance issues associated with the KAFO.
Free Swinging KAFOs are also compatible for use without additional mobility aids, providing sufficient support for patients who can maintain balance and stability on their own.
Achieving optimal mobility with a KAFO can involve a multidisciplinary approach, where our Orthotists work with Occupational Therapists, and Physiotherapists to assess balance needs, prescribe the appropriate device(s), and develop strategies that enhance overall safety and function for the patient.
Customisation and Future Adjustments
Free Swinging KAFOs can be adjusted or modified as a patient’s condition changes.
Whether it’s updating the fit, replacing worn components, or upgrading to a more advanced model, regular check-ups with an orthotist are essential to ensure the device continues to meet the patient’s needs.
If a patient hasn’t seen their orthotist in over a year, it’s advisable to schedule a review to assess the condition and fit of their KAFO.
At Orthotics Plus we regularly take patients from old style designs to modern, lighter and stronger technology. We can however remake and copy older designs if the patient prefers this.
Creating Wonderful Outcomes
The success of a Free Swinging KAFO is measured by its ability to achieve the patient’s goals.
Whether it’s alleviating pain, or improving walking capacity, our orthotist will work closely with the patient to ensure the device meets their needs and enhances their quality of life.
The Orthotists at Orthotics Plus have our patient’s goals at the heart of our work.
