3R60 Knee

An Extreme Makeover

We've taken the excellent walking comfort and stability of the 3R60 and made them even better. The newest version of our 3R60 "EBS" knee has improved hydraulic features so that it 'keeps up' with your patient at almost any cadence, while maintaining the outstanding security created by its polycentric design.

The 3R60 is re-designed to fit heavier weight patients, up to 275 lbs (125 kg), all while losing 10% of its weight. Adjustable swing phase hydraulic and stance resistance round out the changes that will rank this knee as the most effective (and most popular) makeover on the market.

The Ergonomically Balanced Stride (EBS) feature offers more comfort and safety - especially on uneven terrain, inclines and declines - by acting as a shock absorber and flexing as much as 15 degrees during loading (Phase B). This improved EBS stance flexion feature - individually adjustable to the weight and activity of your patient (Fig. 5 below) - greatly improves knee stability and increases walking comfort while allowing for a more natural gait pattern.

With polycentric knee joints, the Instantaneous Center of Rotation (ICR), which helps to determine the stability and safety of the knee joint during stance phase, lies at the crossover point of the extrapolated lines that pass through the posterior and the anterior linkage axes (Fig. 1).

The ICR influences the stability and safety during the loading response phase. During this stage of stance phase, the proximal joint sections of the 3R60 move posteriorly around the lower axis (Fig. 2, A) which in turn shifts the ICR proximally and posteriorly (Fig. 2, B). When compared to other prosthetic knee joints at leading response, the stability of the 3R60 greatly increases with knee flexion.

The blue rubber bumper of the EBS unit is compressed as the pivoting rocker rotates upwards to create a damping effect, (Fig. 2, C) and the rocker can be used to check how much of the EBS function is being utilized by the amputee (Fig. 3). A hydraulic system within the EBS provides an extension dampening effect during late stance phase, for a more comfortable gait.

• New powerful and easy to adjust swing phase hydraulic (Fig. 4) with easy swing initiation and high swing extension damping to accommodate an even greater range of cadences.

• Polycentric design offers increased toe clearance during swing phase resulting in greater confidence in the prosthesis.

• 4 modular connector options to accommodate different amputation levels (Fig. 6).

• Larger flexion angle up to 175° (Fig. 7).

The 3R60 EBS Knee is recommend for use with the C-Walk (1C40), Axtion (1E56) (order with firm heel), Axtion DP (1E58) (order with firm heel), Dynamic Motion (1D35) and Cosmetic Cover 3S107.
