Introduction Peripheral nerve blocks are an efficient method of pain control after total knee arthroplasty (TKA), but there is no report their impact on chronic post-surgical (CPSP). Methods This prospective observational study aimed to assess adductor canal block (ACB) and IPACK (blocks vs. blocks) opioid consumption, postoperative score, 2 years TKA. Results 166 patients (82 84) were analyzed. Opioid consumption was less in the group with (9.74 ± 3.87 mg 30.63 11.52 mg) ( p < 0.001). CPSP present 20.24% without 6.1% = 0.011). Predictor variables included before surgery (cut-off 5.5), at rest 2.35), during active movement (cut-off: 2.5), 8 mg). Conclusion provide adequate analgesia, significantly decrease improve functional outcomes, reduce surgery.
