Optimal pain management after total knee arthroplasty (TKA) can expedite postoperative recovery, improve perioperative outcomes, and increase patient satisfaction. Periarticular injections (PAIs) have become increasingly used to improve pain management after TKA. Similar to peripheral nerve blocks, the use of intraoperative PAIs can lower pain scores and expedite discharge from the hospital. However, there is notable variability in the ingredients and administration techniques of PAIs. Currently, no standard of care exists for PAIs, especially in the setting of adjuvant peripheral nerve blocks. This study seeks to evaluate the ingredients, administration techniques, and outcomes of PAIs used during TKA.
全膝关节置换术后（TKA）的最佳疼痛管理可以加速术后恢复，改善围手术期结果，并提高患者满意度。关节周围注射（PAIs）已越来越多地用于改善 TKA 后的疼痛管理。与周围神经阻滞类似，术中 PAIs 的使用可以降低疼痛评分并加快出院速度。然而，PAIs 的成分和给药技术存在显著的可变性。目前，PAIs 没有标准的护理方法，特别是在辅助周围神经阻滞的情况下。本研究旨在评估 TKA 中使用的 PAIs 的成分、给药技术和结果。
