The Cheetah Knee is a lightweight polycentric knee with 3-phase hydraulic swing control, specifically designed for rapid flexion and extension for running and sprinting. The polycentric design offers stability in stance, allowing for controlled deceleration enabling users to participate in a wide range of sport activities. Although not specifically designed for walking, Cheetah® Knee’s 4-bar geometry makes it possible to walk and easily transition from walking to jogging and/or running.Short knee center to top distance, useful for long transfemoral limbs or knee disarticulationSoft extension bumperMale pyramid distal connection for easy alignment

The Total Knee® 1900 is designed for single speed ambulators and accommodates everyday walking requirements. The swing phase is controlled and steady, while the extension promoter assists in limiting heel rise and moving the knee into a fully extended position.Low build heightPolycentric knee with geometric locking systemDesigned for single speed ambulatorsUnique swing phase control through use of friction within an elastic polymer mediumAdjustable stance flexionAdjustable extension promoter

The Total Knee® 2000 features improved shock absorption, increased comfort and a more natural gait. Mid-swing shortening offers increased toe clearance during swing to prevent hip-hiking and 3-phase hydraulic swing control accommodates changes in walking speed. The adjustable stance flexion feature mimics the knee flexion that occurs during early stance, reducing shock and stress on the residual limb.Low build heightDesigned for multi-speed ambulatorsPolycentric knee with geometric locking systemSwing control adjustments through 3-phase (3-valve) hydraulic systemAdjustable stance flexionAdjustable extension promoter

The Total Knee® 2100 is a polycentric knee with 3-phase hydraulic swing control designed to withstand the rigors of more active amputees. The Total Knee® 2100 offers increased stability, control, efficiency and durability.Low build heightPolycentric knee designed for multi-speed ambulation, high impact levels and heavier loadsGeometric locking systemAdjustable stance flexionAdjustable extension promoter
