The primary purpose is to evaluate whether a combination of two specific nerve blocks administered by an anesthesiologist (Femoral Triangle Block + iPACK block) resulted in superior postoperative pain control compared to a hybrid combination of a nerve block and a local infiltration administered by the surgeon (FTB + Periarticular Infiltration \\[PAI\\]).\n\nThe hypothesis is that the FTB + iPACK combination is associated with a significant reduction in Numeric Rating Scale (NRS) pain scores with movement at 24 hours postoperatively. This is a retrospective, observational cohort study conducted at a single center, involving medical records of patients who underwent primary unilateral TKA. Data from patients who received either FTB + iPACK or FTB + PAI as part of their standard clinical care will be extracted and analyzed retrospectively.",[25,26],"Pain, Postoperative","Osteoarthritis, Knee \u002F Osteoarthritis, Hip",[28,29,30,31,32,33,34,35,36,37,38,39,40,41],"Total Knee Arthroplasty","TKA","Postoperative Pain","Pain Management","Analgesia","Nerve Block","Femoral Triangle Block","FTB","iPACK block","Local Infiltration Analgesia","Timed Up and Go Test","Straight Leg Raise","Periarticular Infiltration","Regional Anesthesia","NOT_YET_RECRUITING","2026-05-28",{"date":45,"type":46},"2026-06-01","ACTUAL",{"date":48,"type":21},"2026-05-01",{"date":50,"type":21},"2026-08-01",{"name":52,"class":53},"Turgutlu State Hospital","OTHER"]
