Brief summary

In this prospective, assessor-blinded, single-surgeon clinical trial, the goal was to validate the efficacy of PAI in aACLR surgery with a reduced opioid dose, while achieving similar pain relief with few adverse events. 300 patients who had undergone aACLR were randomly allocated to receive either a PAI or nPAI group. The primary outcome parameters were visual analogue scale (VAS) scores and cumulative morphine dose, through time. Secondary outcome parameters included drug-related adverse events.

Interventions

COMBINATION_PRODUCTPeriarticular injection

A 50ml periarticular injection was introduced intraoperatively before the time of closing. The injection contained 150mg bupivacaine (3mg/mL), 60mg ketorolac(1.2mg/mL) and 1mg morphine. Before wound closure, periarticular cocktail was injected around the knee joint including the adductor canal from the hamstring harvest side in PAI group. All patients had oral paracetamol 500mg, 4 times/day and diclofenac 75mg, 1 times/day after surgery.
