A prospective comparative study between the effect of adductor canal block and femoral nerve block on early pain management among post-operative unilateral total knee arthroplasty patients

Abstract

Analgesia after TKA can be achieved by integrated multimodal analgesic protocols using two or more analgesic modalities that work by different mechanisms that will optimize the analgesia and minimize the potential risks and side effects. The study was a prospective, randomized Trial. It was approved by the Ethics Committee. All the patients who were diagnosed clinically and radiologically as severe osteoarthritis of the knee planning for unilateral TKR were selected for the study. Written informed consent was obtained from all patients. When patients during the postoperative period were asked to perform the TUG and 10-min walk tests, all patients in the ACB group were able to perform it on POD1 and POD2, whereas in the FNB group, four patients were not able to complete the walk test (fall risk) on POD1 but all of the patients performed the test on POD2. Furthermore, patients in the ACB group performed both tests significantly faster than the FNB patients on POD1.
