Proteor · Hydraulic and pneumatic knees · PR-027
The Proteor Hytrek is a single-axis prosthetic knee with hydraulic regulation of stance and swing and a hydraulic brake that works over a wide range. It is weather resistant and made from aluminium, stainless steel and titanium. The standard knee weighs 1,265 g and stands 232 mm tall. A KD variant with a threaded top weighs 1,285 g. Both flex to 120 degrees and carry 150 kg.
For active K3 and K4 users with a transfemoral amputation or knee disarticulation, including heavier users up to 150 kg who walk outdoors in changing weather. A prosthetist selects the standard or KD version and aligns it.
This kind of device is prescribed and fitted by a clinician. An enquiry starts that conversation. It is not a purchase.
