Highly flexible knee sleeve for vacuum socket prostheses Indications: Below-knee amputation Mobility classes 1, 2, 3, 4 Vacuum socket prostheses Properties: The prosthesis adheres to a large area of the residual limb thanks to the vacuum socket, i.e. the vacuum in the socket causes the prosthesis to stay on (e.g. due to the medi Liner PROTECT 3C Cushion + medi Genu knee sleeve and the medi Vacu air expulsion valve) Airtight joint with the prosthesis socket, thus securing the prosthesis Highly flexible thanks to the special medi round knit technology, thus providing extensive freedom of movement for prosthesis wearers
