An orthopedic method and device for correcting instability of an injured hinge joint. The device includes fixed and rotating rigid members connected by a pair of elongated, generally cylindrical shafts. When the device is mounted in place, a single end-threaded pin disposed through the fixed rigid member defines an axis of rotation, allowing the rotating rigid member, which is connected to the rotating member, to go through a range of motion so that the respective joint is not restricted. This motion mimics that of a natural joint and is made possible because the single end-threaded pin is not fixed in place by any structure other than the center-of-rotation bone and the fixed rigid member in which it is a supportably nested. The invention can include an operational surgical method for using the device to correct instability in the injured hinge joint.
