The joint position in which articulating bones have their maximum area of contact with each other. It is in this position that joint stability is greatest. The close-packed position for the knee, wrist, and interphalangeal joints is at full extension, and for the ankle joint at full dorsiflexion. Any movement away from the close-packed position takes a joint into the loose-packed position in which the area of contact and joint stability is reduced.
