Activity
help/performed
The widespread and standardized “Timed Up and Go Test” (TUG) [The patient’s independent activities were evaluated preoperatively and daily starting from the first to the fifth postoperative day. The recorded standard activities were divided into getting up, personal hygiene, dressing, sitting, walking and going to the toilet (not performed/performed with much help/performed with little help/performed without help). In addition, the passive range of motion (flexion/extension) was measured in degrees, the walking distance in meters and the floor count in absolute floors. All of these variables made it possible to evaluate detailed information of mobilization in the immediate postoperative course during the first postoperative week.
