BACKGROUND: Often anterior cruciate ligament (ACL) reconstruction is performed as outpatient surgery. This requires a patient friendly postoperative pain management. Three common procedures were compared in this trial. METHODS: In a prospective, randomized study the effect of postoperative pain management using preoperative intraarticular anesthesia (0.1 mg Fentanyl + 8 ml Bupivacain 0.5%) was compared with postoperative intraarticular anesthesia (0.1 mg Fentanyl + 8 ml Bupivacain 0.5%) and the femoralis 3-in-1 nerve block (20 ml Prilocain 1% + 20 ml Bupivacain 0.5%) in 157 patients who underwentarthroscopic ACL-plasty. RESULTS: Preoperative intraarticular anesthesia and the femoralis 3-in-1 nerve block showed the same postoperative analgesia and satisfactory pain scores in most cases. Postoperative intraarticular anesthesia was less effective. CONCLUSION: Our data show that in anterior cruciate ligament reconstruction preoperative intraarticular analgesia withBupivacain/Fentanyl is satisfactory and equal to the femoralis 3-in-1 nerve block with Bupivacain.
