A stabilizing assembly includes a fastener having an upper end and a lower end, a head at the upper end, and at least one anchoring element extending between the upper and lower ends. A radio resource allocation unit allocates, to the communication terminal, an uplink frequency band for use in transmission of the known signal from a plurality of unit frequency bands lined in a frequency direction. The positioning assembly can further include a light emitter mounting member configured to receive a light emitter, a channel configured to receive a depth selector slide, and a varus-valgus adjustment member configured to adjust a position of the positioning assembly relative to the femur to achieve a desired varus-valgus angle.
