The 3R62 Pheon polycentric prosthetic knee joint is especially well suited for prosthesis wearers with low mobility, since it provides the corresponding functionality for swing and stance phase control. At the same time, the 3R62 supports the therapy goal of restoring the ability to stand and moderate ability to walk indoors and outdoors. Thanks to the integrated optional lock, which can be activated or deactivated by the prothetist, the 3R62 Pheon provides targeted support for the post-amputation therapy process – from the initial standing and walking exercises with the interim prosthesis through to the definitive fitting.
