  "abstract": "Background and Aims Knee replacement (KR) surgery is associated with significant pain, with up to 60% of patients experiencing moderate to severe postoperative discomfort. Inadequate pain control may lead to chronic postsurgical pain (CPSP) in up to 44% of cases. Perioperative nerve blocks can improve acute pain and potentially reduce CPSP. This survey aimed to describe current UK practices in regional analgesia for KR.Methods An anonymous, self-administered online survey was distributed to anaesthetists involved in KR surgery across NHS hospitals in the UK.Results A total of 324 responses were received between 31st October 2023 and 28th November 2023 from 12 UK regions (92.6% from consultants). Nerve blocks were reported as ‘always’ used by 137 respondents (42.3%), ‘most of the time’ by 42 (13%), and ‘sometimes’ by 43 (13.3%). The adductor canal block was the most common (209 responses, 64.5%), followed by iPACK (43, 13.3%). Regarding local infiltration analgesia (LIA), 89.5% reported its use in over 75% of cases. Single-shot blocks were preferred over continuous infusions (73.8% vs. 0.6%). Barriers to nerve block use included the belief that LIA alone was sufficient (41%), time constraints (21.9%), and lack of skill (19.4%); 42.6% reported no deterrents.Abstract OP59 Figure 1Do you use any regional nerve Blockade technique (other than neuraxial blockade and infiltration of local anaesthetics done by surgeons) for knee replacement?Abstract OP59 Figure 2What is the regional analgesia technique that you use most often for knee replacement?Abstract OP59 Figure 3Which of these options best describes the mainstay of your postoperative pain management for knee replacement?Conclusions There is variability in regional analgesia practices for KR in the UK. The adductor canal block is most commonly used, and LIA is widely adopted. These findings may guide future research for the development of evidence-based guidelines on the use of regional analgesia in KR surgery.",
