You will be admitted to the hospital the morning of your surgery.  The surgery takes about 1-1/2 hours and the patient is hospitalized for 1-2 days.  Many patients are partially weight bearing prior to their discharge from the hospital.  The procedure involves restoring about 1/3 of the joint surface.  Due to the small amount of bone that is resected to implant the device, there is a maximum preservation of tissue, the ligaments are retained and the remaining knee compartments remain intact.
