A combination crutch and knee walker device converts between a rolling knee walker configuration and a crutch configuration through a single folding or expanding articulation that requires no tools or skillset. The device includes a first support bar that forms the primary lever of support. A second support bar pivotally joins the first support bar at a hinged junction, generally three-quarters down from the top of the first support bar. The support bars fold and expand about the hinged junction to convert between crutch and knee walker. A panel hingedly joins at the hinged junction serving as a supportive platform for an upper body, such as the arm or the knee, depending on the crutch or knee walker configuration. Further, the mobility function, such as rolling rollers, will restrict or free rotation depending on the selected configuration of the device.
