THR: Wound Closure

    - place leg on padded Mayo stand in 10 deg of abduction to relieve tension on leg;
    - deep soft tissue repair:
            - repair of posterior capsule and reattachment of the external rotators (which may help to decrease posterior dislocation);
            - there is some evidence to suggest that external rotator muscle repair is doomed to failure;

    - wheel vac:
            - inorder to address wound complications that may arise from aggressive CPM activity, consider an inexpensive vaccum suction device;
            - technique:
                - apply several layers of gauze over the incision;
                - apply a "jackson pratt" type drain over the gauze (multi holed tube is positioned over the gauze) with the non-fenestrated
                          portion of the tubing exiting outside the gauze;
                - "tegaderm" is applied over the gauze and the tubing;
                - hook the tubing upto the hospital suction at 125 mm HG;
    - superficial closure:

    - need to drain THR is controversial:
            - some surgeons place one drain deep to fascia, and if the patient is obese, then one drain superficial;
