Anesthesia for the patient undergoing total knee replacement: current status and future prospects

Area of Science:

• Orthopedic Surgery
• Anesthesiology
• Pain Management

Background:

• Total knee arthroplasty (TKA) is a common orthopedic procedure with evolving anesthesia and analgesia practices.
• Historically, general anesthesia dominated TKA, but regional techniques are gaining prominence.
• The shift reflects a growing understanding of improved patient outcomes associated with regional anesthesia.

Purpose of the Study:

• To review the evolving trends in anesthesia and analgesia for TKA.
• To highlight the benefits of regional anesthesia and multimodal analgesia.
• To discuss the development of clinical pathways for enhanced TKA recovery.

Main Methods:

• Literature review of studies on anesthesia and analgesia in TKA.
• Analysis of trends in anesthetic techniques and pain management strategies.
• Examination of the impact of clinical pathways on patient outcomes.

Main Results:

• Regional anesthesia is associated with decreased intraoperative blood loss, shorter hospital stays, and reduced mortality compared to general anesthesia.
• Multimodal analgesia, incorporating nerve blocks and periarticular injections, effectively manages pain while minimizing opioid use.
• Clinical pathways streamline TKA care, improving quality, reducing variation, and lowering costs.

Conclusions:

• Regional anesthesia and multimodal analgesia represent significant advancements in TKA perioperative care.
• Formalized clinical pathways are crucial for optimizing pain control and rehabilitation, leading to faster patient recovery.
• The future of TKA management involves integrated approaches to anesthesia, analgesia, and recovery protocols.
