Devices that are implantable within a patient's body, and more specifically, to implantable joints (e.g. hip joint, knee joint, shoulder joint, etc.) having a heating system. For example, a device implantable within a patient's body may include a first member configured to be coupled to a first bone and a second member configured to be coupled to a second bone, the first and second members being operatively coupled to form a moveable joint. A heating system may be configured to controllably heat at least a portion of the at least one of the first and second members. The heating system may include a controller operable to cause a heating element to apply heat based on one or more external conditions (e.g. temperature, humidity, etc.).
