2.3. Outcome assessment
blood loss, SSI, cold injury, DVT
BLOOD LOSS, SURGICAL SITE INFECTION, PERIOPERATIVE COMPLICATION, INTRAOPERATIVE BLOOD LOSS, DVT
Intraoperative blood loss, postoperative drainage volume (PDV), VAS at rest and walking on postoperative day 1 (POD1), POD2, POD3, ROM (POD3, 7, discharge, postoperative month), circumference variation (POD3, 7), postoperative length of stay (p-LOS), function score (Hospital for Special Surgery [HSS], discharge) and drop of Hb on POD3 were recorded. Total number and dose of oxycodone, postoperative prothrombin, activated partial thromboplastin time, and perioperative complications (surgical site infection [SSI], DVT, cold injury) were also noted. The total blood loss (TBL) and hidden blood loss (HBL) were calculated by the methods of Nadler.
