Above Knee Prosthetics

Any volume changes will make the prosthesis more difficult to keep on your leg well. You do not have to worry about liners or socks which is a plus.

Gel suspension can be either with pin lock system or a lanyard system.  This system is more forgiving for volume changes in your leg. If you are a new amputee this may be a better option for the first socket. Then as your leg becomes more mature you c n consider the suction system.

Most feet nowadays are designed with some kind of energy return. The choice for the right foot and knee interface depends on your activity leve land how well you can manage goals of prosthetic use.
