epX #6331 Deluxe Hinged Knee Support with adjustable hinges. Two circular straps on the thigh and lower leg and two straps immediately above and below the patella, alternately wrapped in right and left direction, as well as lateral anatomically preshaped metal splints with hinged joints. For the protection of damaged ligaments, the range of movement during flexion and extension of the knee, which is guided by the lateral splints, can be limited as required by adjusting the hinges in 10=C2=B0 and 20=C2=B0 steps.= A ring-shaped insert is integrated into the patella area.
