Preoperative Physical Activity, Anesthesia, and Analgesia: Effects on Early Postoperative Walking After Total Hip Replacement

Abstract This study explored whether preoperative activity, anesthesia, or analgesia influence early postoperative walking after total hip replacement (THR). Data were collected as part of a randomized intervention study of standard or augmented postoperative activity and its influence on wound healing. More than half of all subjects did not exercise regularly. Subjects who performed strength activities preoperatively walked significantly greater distances. Anesthesia or analgesia did not affect walking distances. Upper arm strength is needed after THR because walking is dependent on the use of assistive devices. These results suggest: (1) preoperative exercise may promote recovery of mobility after THR, and (2) a need to evaluate preoperative exercise programs for effect on mobility and independence after THR.
