NCT05427019

Brief Summary

Continuous administration of local anesthetics to the distal adductor canal could spread into the popliteal fossa and contribute to analgesic effects on posterior knee pain. Periarticular local anesthetic infiltration is a component of multimodal joint pathways and the posterior knee capsule was among the tissues routinely infiltrated. It is expected that there will be overlapping effects of distal adductor canal block and periarticular injection. Therefore, we aim to compare the postoperative pain in the group that received only continuous distal adductor canal block and the group that received both continuous distal adductor canal block and periarticular injection. Sixty-six patients scheduled for total knee arthroplasty will be randomly divided into the two groups. In group 1, the adductor canal catheter is inserted 2cm above the adductor hiatus. In group 2, the adductor canal catheter is inserted where the nerve block performed in group 1 and periarticular injection are performed intraoperatively.

Outcome Measures

Primary Outcomes (1)

  • Numeric rating scale pain score

    Pain intensity at rest evaluated by an 11-point numeric rating scale (NRS: 0 = no pain, 10 = worst imaginable pain)

    postoperative 1 day morning (08:00-09:00 AM)

Secondary Outcomes (1)

  • Numeric rating scale pain score

    postoperative 6 hours, postoperative 1 day afternoon (4:00-5:00 PM), postoperative 2 day morning (08:00-09:00 AM)

Study Arms (2)

Distal adductor canal block

ACTIVE COMPARATOR

Participants receiving continuous distal adductor canal block

Procedure: Distal adductor canal block

Distal adductor canal block and Periarticular block

ACTIVE COMPARATOR

Participants receiving continuous distal adductor canal block and periarticular block

Procedure: Distal adductor canal block and Periarticular block

Interventions

All catheters were inserted under a full aseptic technique using a real-time ultrasound-guided in-plane approach by an experienced anesthesiologist. The adductor canal catheter is inserted 2cm above the adductor hiatus.

Distal adductor canal block

All catheters were inserted under a full aseptic technique using a real-time ultrasound-guided in-plane approach by an experienced anesthesiologist. The adductor canal catheter is inserted 2cm above the adductor hiatus.The periarticular injection solution contained 20mL of 7.5 mg/mL ropivacaine, 30mg of ketorolac, and 0.3mL of 1.0 mg/mL epinephrine. These agents were mixed with normal saline to a combined volume of 50mL. The surgeon injected this mixture into the tensor fascia lata, subcutaneous tissues, abductors, short external rotators muscles, and structures in the capsule.
