Abstract

Purpose: The study aimed to evaluate efficacy of an intraoperative periarticular injection (PAI) in improving postoperative outcomes, including pain relief and reducing opioid consumption in patients undergoing arthroscopic anterior cruciate ligament reconstruction (aACLR) with hamstring tendon autograft.

Methods: This prospective, assessor-blinded, two-surgeon clinical trial was conducted from. March 20th , 2022 to June 20th, 2022. A total of 320 patients were initially. Included, and after screening and exclusions, 300 patients undergoing aACLR were randomized to receive either PAI or were assigned to the nPAI group. Inclusion criteria consisted of patients aged 18 years or older undergoing primary aACLR, with or without a concomitant meniscus procedure for knee instability, who agreed to participate and provided informed consent for randomization into the PAI or nPAI group. The minimum follow-up period was two weeks postoperatively. The primary outcome was decreased visual analogue scale (VAS scores) and cumulative Morphine Milligram Equivalents (MME). The secondary outcome parameters included decrease in narcotic-related adverse effects.

Results: 142 patients in the PAI group and 146 patients in the nPAI group were analyzed. In the PAI group, a lower VAS score at immediate postoperative period and postoperative 4-hour and 24-hour 24 was observed compared with the nPAI group. Proportions of patients achieving MCID were higher in the PAI group at all time points compared to nPAI. Cumulative morphine consumption was significantly reduced in the PAI group (p<0.001).

Conclusions: PAI during aACLR with hamstring autograft significantly improved pain scores and reduced opioid consumption compared to nPAI. While statistical differences were found, cohort-specific MCID analysis showed a clinically relevant benefit at 24 hours, with 54.2% of the PAI group achieving meaningful pain relief versus 23.3% in the nPAI group. These results suggest that PAI offers time-dependent, patient-specific benefits and supports its role in multimodal analgesia.

Level of evidence: Level II - Randomized controlled trials.

期刊介绍: Nowhere is minimally invasive surgery explained better than in Arthroscopy, the leading peer-reviewed journal in the field. Every issue enables you to put into perspective the usefulness of the various emerging arthroscopic techniques. The advantages and disadvantages of these methods -- along with their applications in various situations -- are discussed in relation to their efficiency, efficacy and cost benefit. As a special incentive, paid subscribers also receive access to the journal expanded website.
