Perioperative pathway for patients between ERAS and traditional groups.

ERAS group	Traditional group
Preoperative interventions
Instruction and education  Egg white  Preoperative analgesia  Anxiety management  Clear oral liquids up to 2 h before surgery  Moxapride (5 mg) 3 h before surgery  No urinary catheter (unilateral UKA)	Instruction and education No egg white No preoperative analgesia No Anxiety management Oral liquids up to 6 h before surgery No prevention of postoperative nausea and vomiting Urinary catheter
Intraoperative interventions
Intraspinal anesthesia combined with femoral never block  Restricted infusion (<1500 mL)  Local injection of cocktail  Intra-articular perfusion of tranexamic acid (1 g)  Intravenous dexamethasone (10 mg)  No drainage tube  Controlled blood pressure  Warm saline rinses	Intraspinal anesthesia No restricted infusion Local injection of cocktail No intra-articular perfusion of tranexamic acid No application of dexamethasone Drainage tube (24–48 h) No controlled blood pressure Saline rinses
Postoperative interventions
Early initiation of oral intake  Intravenous tranexamic acid (1 g, 3 h/6 h/9 h)  Ice therapy  Multimodal analgesia  Intravenous dexamethasone (10 mg, 4 h/24 h)	No early initiation of oral intake No intravenous tranexamic acid No ice therapy No multimodal analgesia No intravenous dexamethasone

ERAS = enhanced recovery after surgery, UKA = unicompartmental knee arthroplasty.
