1. A joint distraction device, comprising:
a first member comprising an insertion end configured to be inserted between a first bone and a second bone of a joint, the insertion end comprising a cavity therein;
a hinge coupled to the first member;
a second member comprising a distal portion and a proximal portion, the second member coupled to the hinge at a position between the distal portion and the proximal portion, wherein the distal portion is configured to be received within the cavity of the insertion end and inserted between the first bone and the second bone when the insertion end is inserted therein;
a third member coupled to the hinge and manipulable to exert a force on the proximal portion of the second member that causes the distal portion to rotate about the hinge and away from the insertion end while the distal portion and the insertion end are inserted between the first bone and the second bone, thereby distracting the first bone from the second bone; and
a disposable force sensor pod configured to be removably coupled to at least one of the second member or the third member.
