The aim of this study is to investigate the effectiveness of combined adductor canal block (ACB) with interspace between popliteal artery and the knee capsule (IPACK) versus combined ACB with genicular nerve block (GNB) for providing analgesia in knee arthroplasty. The investigators hypothesize that the analgesic efficacy of ACB combined with GNB will be non-inferior to that of ACB combined with IPACK. Additionally, the investigators aim to assess whether the combination of ACB and GNB results in a significantly lower occurrence of sensory or motor block affecting the tibial and common peroneal nerves compared to ACB and IPACK
