The All New CrossOver
Prosthetic Knee
Don't Let Life Define Your Limitations
Active lifestyles require prosthetics that can keep pace.
The Crossover™ Hybrid Knee is a monocentric (single axis) articulated Extensible knee that can be used for general ambulation or — with simple adjustments — transforms into a dynamic prosthetic that can used for high activity sports like downhill skiing and mountain biking.
Take A Walk On The Wild Side.
Walking knees are good for walking only and sport knees are not good for walking. That’s a big problem for the user with real life transitions from one activity to the next. Crossover™ bridges that gap, the world’s first hybrid knee that delivers high performance in all activities.
You will be amazed at what you can do with this knee! Crossover™ allows you to make adjustments on the spot with no tools. Shred the hill and then walk to the lodge!
ALL-WEATHER PROOF!
Dirt, Water, Snow, the Crossover will continue to perform regardless of what Mother Nature throws at it. You never have to worry about losing functionality from a dead battery or an overheated microprocessor.

Technological Innovation
The patented tendon system is the heart of the Crossover™ knee, offering a highly variable and infinitely tunable resistance and return mechanism. This relatively linear spring rate of tendons and X/CAM™ system delivers a smooth, even energy absorption and return. This patented tendon and X/CAM™ system is what makes it possible for the user to get extension/resistance moments that provide the needed assistance to enable exiting and absorbing the extreme flexion moments associated with sport activities
The Crossover™ knee utilizes a pneumatic/hydraulic shock. This shock uses a combination of air, oil and valving to control and change flexion and extension moments. Air pressure is user adjustable and the regulated air spring/air pressure determines how firm that spring is. The user controls enables regulation of flexion and extension rates. Similar in function to the S-N-S Mauch units this pneumatic/hydraulic shock provides the ability to manage average ambulation requirements, and when combined with the tendon, X/CAM™ and Cross- flex™ wedges, provides the additional dampening and rebound for high activity sports
Crossflex™ preflexion wedges are a mid-durometer foam wedge system that is user added to change the preflexion angle/position per sport activity. Different sports require different preflexion settings. Snowboarding for example may require 30° whereas mountain biking may do better at 10°. Crossflex™ wedges are designed to act like knee cartilage providing compression absorption reducing stress on prosthetic limb.
Crossflex™ wedges require no tools to add to the knee and are inserted at the knee axis. 20° | 30° and 40° angle/positions available.
VED bumpers come in 75° and 85° durometer ratings and can be interchanged to address knee performance during stance phase.
