  "abstract": "Background and Aims Total knee arthroplasty (TKA) is associated with significant postoperative pain. The aim of this study was to compare postoperative oral and parenteral analgesic therapy depending on the use of a single-shot femoral block at the end of surgery versus bolus administration of local anesthetic via a femoral catheter.Methods A retrospective observational study was conducted on 128 patients who underwent TKA in 2024. Based on power analysis, 64 patients were included per group. One group received a single 20 ml dose of 0.25% levobupivacaine at the end of surgery. The other had a femoral catheter placed and received the same initial dose, with the option of up to three additional boluses daily for 48 hours. Postoperative analgesics included parenteral ketoprofen, paracetamol, metamizole, oxycodone, and tramadol, as well as oral tramadol/paracetamol, short-acting morphine, and oxycodone/naloxone.Results Groups were comparable in terms of sex, age, ASA status, and anesthesia type. No significant differences were observed in the use of paracetamol, metamizole, oxycodone, and tramadol, as well as oral tramadol/paracetamol, short-acting morphine, and oxycodone/naloxone on postoperative days 0 and 1. However, ketoprofen use on day 1 was higher in the single-shot group (180 mg vs. 151 mg; p < 0.05). In the catheter group, 56.2% received at least one bolus on day 0 and 71.4% on day 1.Conclusions Overall postoperative analgesic use did not differ between groups, although the lower use of ketoprofen in the catheter group may reflect the additional local anesthetic option. However, the femoral catheter was not fully utilized as a method of pain control.",
