The 3R38 Modular Single Axis Knee Joint and the 3R39 with Lock are to

lower limb (fig. 1).
The use of these components is limited to patients up to 145 cm (4'9")
tall with foot lengths up to 21 cm and weighing up to 45 kg (99 lbs).
The knee axis (4) is placed 8 mm posterior to the weight bearing line and
provides connection between the upper joint section (1) and the lower joint
section (2) in which the extension mechanism is accom modated.
The integrated lock mechanism secures the 3R39 Joint in extended posi-
tion. By means of the lock cord, coming out from the upper joint section,
the lock is released and flexion may take place.
