In the context of medical recovery from injury and/or surgery to a lower extremity, a device may be used to provide elevation and support for a patient's foot, including ankle and heal, along with restraint against rotation of the lower leg of a patient. This can protect the knee from injury. The device may include a generally flat main body, two spaced-apart lateral ridges extending along or near lateral edges of the generally flat main body, and a medial depression between the lateral ridges that provides a support surface on which the ankle may be positioned.
