A limb support device for supporting a limb of a patient, the limb including an upper limb above a joint and a lower limb below the joint, the device having an upper limb support for supporting the upper limb but not the lower limb, so that the lower limb can articulate about the joint when the upper limb is being supported by the upper limb support. A lower limb support is arranged for engaging the lower limb only, and for raising and lowering the lower limb by articulation about the joint, so that, while the upper limb is supported by the first part, the second part is moveable between a position where it is remote from the lower limb and a position in which it engages the lower limb.
