Blatchford is pleased to announce our new K2 Hydraulic Ankle with integrated elevated vacuum.
The Avalon Range is designed specifically for the complex needs of all K2 limited community ambulators. Through a combination of award-winning hydraulic ankle technology and a unique optimised keel, Blatchford has created a family of products that work with the user to enhance confidence, independence and safety for all K2 amputees.

“I can go and do my voluntary work and I can give it my all.”
AvalonK2 is an ideal solution for all K2 users especially those who are at the lower levels of K2 spectrum. New AvalonK2VAC is aimed at K2 users with better balance, sufficient dexterity & cognitive function and who have a higher mobility level. It will be particularly suitable for those with the potential to improve their mobility and progress to K3 or a K3 amputee whose mobility has declined to a K2 level.

Hydraulic ankles help align the body interface with the ground interface, allowing for more natural movement and posture. By continuously adjusting to absorb energy, our hydraulic ankles allow for an efficient roll-over, remaining in a dorsiflexed position, increasing clearance to help reduce the risk of falls. This technology has been proven to provide a number of benefits to limited community ambulators optimising posture and comfort.
AvalonK2 offers a range of motion of 6˚ plantar and 6˚ dorsiflexion with a single hydraulic adjustment function. This range of motion improves ground clearance when walking but also increases stability when sitting down or standing up, a particular benefit for the low activity K2 users.
AvalonK2VAC offers a range of motion of 6˚ plantar and 3˚ dorsiflexion with independent hydraulic adjustment. This function allows the fine tuning of the hydraulics. The improved socket connection created by the elevated vacuum compensates for the slight reduction in motion range as the better connection improves ground clearance and reduces interface pressures, this combination delivers benefits for the higher K2 level user.
Limited community ambulators tend to walk more slowly, with a shorter step and stride length. Providing a foot keel that is designed to accommodate natural changes in gait can provide a smoother rollover for such users. The optimised keel shape of the Avalon range considers such requirements and encourages a consistent, stable, and comfortable rollover so the user can walk more easily and move around confidently.
AvalonK2VAC features integrated elevated vacuum, increasing stability and preserving skin health. The vacuum system creates a more secure socket connection resulting in minimized pistoning, improved symmetry of gait patterns and enhanced proprioception, all improving stability and confidence of the user.
To preserve skin health the elevated vacuum draws blood into the residual limb, providing better circulation. The elevated vacuum improves tissue oxygenation during walking and compared to other prosthetic suspension methods, decreases trans-epidermal water loss and attenuated reactive hyperaemia. A study carried out suggested that decreasing trans-epidermal water loss preserves the skin barrier function, which protects against ulcer formation.
The Silcare Breathe liner is highly recommended for use with AvalonK2VAC. Its unique design transmits moisture away from the skin to ensure a comfortable, cool and secure fit.
To take a more in-depth look into the Avalon range, discover our White Paper ‘A Study of AvalonK2’ where the biomechanics of the limited community ambulators gait are considered along with the latest clinical evidence for biomimetic hydraulic technology. Then uncover how the biomechanical performance of AvalonK2 can improve mobility and independence.
While prosthetic technology edges ever closer to restoring natural performance, there is also a more basic consideration – the residuum-socket interface. Even with the world’s most advanced prosthetic limb, if it is not comfortable to wear and walk with, amputees will not use it. Socket fit and comfort are inextricably linked to residual limb health, making this a critical element in achieving and maintaining a successful prosthetic prescription.
Over a decade after challenging conventional wisdom, new scientific evidence continues to be published on the medical advantages of hydraulic ankles. Discover our White Paper ‘A Study of Hydraulic Ankles’.
Blatchford Biomimetic Hydraulic Technology mimics the dynamic and adaptive qualities of muscle actuation to encourage more natural gait. Multiple independent scientific studies, comparing Blatchford hydraulic ankle-feet to non-hydraulic feet, have shown:
