Rhabdomyolysis in an obese patient after total knee arthroplasty

We report the case of a morbidly obese patient who developedrhabdomyolysis with acute renal failure, hepatic dysfunction,and an increase of cardiac troponin-1 after total knee arthroplasty.Postoperative rhabdomyolysis has a wide range of triggers anddifferential diagnoses that should be considered by the anaesthesiologistand surgeons. We would like to emphasize that morbidly obesepatients have an increased risk of developing postoperativerhabdomyolysis potentially leading to life-threatening disease.Intensified postoperative observation seem justified in thesepatients.
