Background and Aims:

The aim of this study is to compare and determine which of the two methods, femoral nerve block or systemic analgesia, is the best considering postoperative analgesia as well as patient satisfaction following anterior cruciate ligament reconstruction (ACLR).


In this controlled, randomized, blinded clinical trial, 80 ASA 1 and 2 patients for ACLR were divided in two groups. Group 1 received preoperatively an ultrasound guided femoral nerve block and group 2 received ketoprofen 100 mg. two times 24 hours for postoperative analgesia. As a rescue analgesic we used Tramadol 100 mg. when the pain according to Numeric Rating Scale was 3 or more. The parameters we measured were pain during rest and during flexion, 6, 12 and 24 hours postoperatively, time of the first request of tramadol, the amount of Tramadol requested for the first 12 hours and the second 12h. (12-24h) postoperatively, side effects and satisfaction score.


There was a significant difference in both rest and movement pain scores in favor of femoral nerve block in all three measurement times. Also the significance was found in time of the first request of Tramadol and the amount for the first 12 hours in favor of  femoral nerve block. There was no difference in the amount of tramadol requested for the second 12 hours and no difference in side effects. Satisfaction score was significantly better in the femoral nerve block group.


Femoral nerve block gives better postoperative analgesia in the first 24 hours compared to systemic analgesia and more patient satisfaction.
