A transfemoral rotator is provided. The transfemoral rotator includes an inner cylinder that nests within a cavity of a base shell. The inner cylinder includes a lower cylindrical hub configured to protrude through an opening in the base shell. A spring clip mechanism operated by a push button serves to lock and unlock the transfemoral rotator to permit for rotation of a lower limb prosthesis and allow for a wearer to sit cross-legged.
