After total knee prosthesis surgery, in the first postopertive days, serious pain complaints occur in the patients and this causes many problems, especially mobility limitation. For this reason, a strong analgesic is needed. As a part of multimodal analgesia after total knee surgery, nerve blocks are frequently preferred. While central nerve blocks are preferred in the forefront, peripheral nerve blocks are frequently preferred due to complications related to central nerve blocks. Femoral nerve block and adductor channel block are the preferred peripheral blocks for total knee prosthesis. Since early mobilization after total hip prosthesis is very important, it is aimed to provide sufficient analgesia by making less motor block. Previous studies have shown that adductor channel block provides similar analgesia with femoral nerve block. Early mobilization, early discharge and the impact on the risk of falls are not yet clear, although it is estimated to be in the positive direction. Again, previous studies have compared single doses and infusion doses but no repeated bolus doses. Repeated bolus doses have been shown to be more effective in studies in which adductor channel catheters have been introduced to date to compare infusion and recurrent bolus doses.
