AvalonK2

Suitable for submersion (up to 1 metre)
Activity Level 2

AvalonK2 is a hydraulic ankle that has been designed specifically for the complex needs of limited community ambulators. Through a combination of award-winning hydraulic ankle technology and a unique optimised keel, Blatchford has created a prosthesis that works with the user to enhance confidence, independence and safety.

Enhancing walking confidence by hydraulically adjusting to inclines and self-aligning to secure the knee joint, AvalonK2 encourages good posture and joint position. This improves stability, helping to prevent falls and increases balanced limb loading to provide the best performance for limited community ambulators.

Key Features

  • Hydraulic ankle technology designed to replicate natural motion
  • Optimised keel shape enhances walking stability
  • Plantarflexion compliance when descending slopes
  • Increased range of motion to enable greater sit-stand transfer safety
  • Increased shock absorption, reduction in interface pressures
  • Remains dorsiflexed for increased toe clearance in swing phase
  • Waterproof
  • Sandal Toe Foot Shell

Foot Shell and Glide Sock included.

AvalonK2 Unique Design

The Avalon range enhances walking confidence by hydraulically adjusting to inclines and self-aligning to secure the knee joint, to encourage good posture and joint position. This improves stability, helping to prevent falls and increases balanced limb loading to provide the best performance for limited community ambulators.

The main driving force behind advancing lower limb prosthetic technology in the 21st century is biomimetic design; reproducing the biomechanical performance of natural limbs. Inherent in this is recognising that different demographics of the amputee population have different biomechanical requirements, and that the engineering principles behind different devices must accommodate for this.

With over 130 years of innovation and expertise in lower limb prosthetic technology our award-winning prosthetic products are designed with the patient in mind.

The Benefits of AvalonK2

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 Range of Motion

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.

AvalonK2 Purpose Designed Keel

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.

White Paper: A Study of Residual Limb Health

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.

Clinical Compendium

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:

  • Greater comfort, reduced socket pressures
  • Improved safety, reduced risk of trips and falls
  • Smoother, easier and more natural gait
  • More evenly balanced inter-limb loading
  • Greater satisfaction
