ABSTRACT
Objective To observe the analgesia efficacy of continuous fascia iliaca compartment block (FICB) and adductor canal block (ACB) on elderly patients undergoing total knee arthroplasty (TKA) with multimodal analgesia and their early rehabilitation. Methods Sixty TKA patients (26 female and 34 male, 60-75 years old) were randomly divided into two groups and received ultrasound-guided either continuous FICB (n=30) or continuous ACB (n=30) using 0.25% ropivacaine for controlled analgesia. All the patients had no previous experiences of knee surgery. Quality of analgesia was assessed by dynamic and static visual analogue scale (VAS) based on pain intensity. In addition, rehabilitation training compliance, range of motion (ROM) and knee function were assessed at different times after rehabilitation training. Results No significant differences were found in VAS scores during resting and passive functional exercise at 6, 12, 24, 48 h after TKA surgery (P>0.05); ACB group had significant differences in rehabilitation training compliance, knee ROM and HSS scores in comparison with FICB group (P<0.05). Conclusions Ultrasound-guided continuous ACB with multimodal analgesia could promote early rehabilitation after TKA．
