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 optimized 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.

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 recognizing 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 128 years of innovation and expertise in lower limb prosthetic technology our award-winning prosthetic products are designed with the patient in mind.
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 optimizing posture and comfort.
An important design consideration of AvalonK2 was to enable the user to stand from a seated position in a safe and comfortable way. In addition to the keel and shape, the 6° of dorsiflexion allows the base of support to be moved closer to the body’s centre-of mass making it easier to sit-stand.
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 optimized keel shape of AvalonK2 considers such requirements and encourages a consistent, stable, and comfortable rollover so the user can walk more easily and move around confidently
To take a more in-depth look into AvalonK2, 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.
