Editorial Commentary: Postoperative Pain Management After Anterior Cruciate Ligament Reconstruction Can Minimize Opioid Use and Allow Early Rehabilitation

Abstract

Effective analgesia is essential after anterior cruciate ligament (ACL) reconstruction to control pain while minimizing opioid consumption and allowing early rehabilitation. Orthopaedic surgeons write the third-largest number of opioid prescriptions, which are responsible for 1/10th of all opioid prescriptions, and one-third of patients with ACL injury use opioids preoperatively, a risk factor for postoperative abuse. Pain management after ACL reconstruction using variety of analgesic regimens including various permutations of nerve blocks, nerve block adjuncts, intra-articular injections, intravenous and oral medications, cryotherapy, compression stockings, and transcutaneous electrical nerve stimulation units, based on multidisciplinary collaboration between surgeons and anesthesiologists, can minimize opioid consumption. A recent meta-analysis shows that combined femoral–sciatic nerve block may be a top-ranked analgesic technique. Femoral and adductor canal nerve blocks are also effective alternatives and most common. Femoral and femoral sciatic nerve blocks may risk quadriceps strength deficits, whereas an advantage of adductor canal nerve is that the saphenous nerve is purely sensory. We recommend longer-acting nerve blockade (72 hours) using continuous anesthetic delivery via a pump/catheter with ropivacaine or the use of a slow-release preparation such as bupivacaine liposome injectable suspension.
