Task: Answer Verification
Input (English): Question: Does severe and morbid obesity ( BMI ≥ 35 kg/m ( 2 ) ) increase surgical time and length of hospital stay in total knee arthroplasty surgery?
Answer: Severely and morbidly obese (SMO) patients (BMI ≥ 35 kg/m(2)) undergoing TKA surgery do not require longer operative time or hospital stay than non-obese or obese Class I patients. The fact that surgical time was not significantly different could be due to greater specialisation in the treatment of these patients, which may favour a lower incidence of post-operative complications.
Output (English): no
