Thanks to easy initiation of the swing phase, the 3R60 knee joint allows you to walk at various speeds – whether you are going for a hike or strolling through a market. You benefit from a larger ground clearance during swing-through of the joint, reducing your risk of stumbling. The special joint design also gives you more stability in the stance phase and prevents unwanted flexion of the joint. The 3R60 also makes it possible for you to walk down gentle slopes.
