Overview

If the fitting was modified from a previous knee joint generation such as the 3B1-2, 3B1-3, 3B5-2, 3B5-3; 3C98-*, 3C88-* to a Genium X4 knee joint (3B5-4=P/3B5-4=ST) or a new Kenevo knee joint (3C60=5/3C60=ST-5) without fabricating a new socket, the changed position of the pyramid/threaded connector has to be taken into account since the pyramid/threaded connector is no longer angled (0°). Use intermediate adapters (e.g. 4R47=*, 4R48=*) to adjust the position if necessary.

The refit adapters help copy the alignment by equalizing the inclination/angle of the knee head when switching from a previous Kenevo model to the updated Kenevo (3C60=5/3C60=ST-5).

If the fitting was from a previous knee joint with an inclination of the knee head (i.e. 5° for 3C60=A*/3*/4*), without fabricating a new socket, the changed position of the pyramid/threaded connector has to be taken into account since the pyramid/threaded connector is no longer angled. Use intermediate adapters (e.g. 4R47=*, 4R48=*) to adjust the position if necessary. This adapter is corrosion resistant.

• 4R48=5.0 for sockets with 4-hole attachment at the distal end of the socket
• 4R47=5.0 for fittings with threaded top knees (ST)
