Total Hip Arthroplasty Revision Surgery: Impact of Morbidity on Perioperative Outcomes

Pflüger, Michael J. et al.


Primary and revision total hip arthroplasty (THA) is increasingly performed in patients with high comorbidity burden. Its predominantly negative effects on outcomes are well understood in primary THA; however, the effects of morbidity on revision THA are unknown. Since revision procedures account for about 10% of the total surgical volume, we set out to investigate the effects of physical health status on perioperative outcomes in this setting.


We queried our prospectively collected institutional database for patients who underwent revision THA at our institution (Orthopedic University Hospital Friedrichsheim, Frankfurt) between 2007 and 2011. Patients were classified according to American Society of Anesthesiologists (ASA) category and number of comorbidities. Subsequently, their impact on perioperative parameters was analyzed.


Our database revealed 294 cases of revision THA during the study period. Patients preoperatively classified as ASA 3 and 4 showed significantly higher rates of intraoperative and postoperative complications, transfusions, prolonged intensive care unit (ICU) stay, and total length of stay (LOS) compared to patients classified as ASA 1 and 2. Similarly, patients with >3 comorbidities presented with significantly elevated postoperative complications, ICU stay, and LOS. Particularly, preoperative cardiac diseases were associated with increased blood loss, transfusions, duration of surgery, postoperative complications, ICU stay, LOS, and re-revisions.


Poor physical health condition is associated with negative perioperative outcomes in revision THA. Especially cardiac comorbidities are linked to unfavorable outcomes, which have important implications for assessment of perioperative risk.
