Anesthesia and analgesia for total knee arthroplasty

Area of Science:

• Anesthesiology
• Orthopedic Surgery
• Pain Management

Background:

• Rising global demand for total knee arthroplasty (TKA) necessitates optimized anesthetic and analgesic strategies.
• Existing literature presents conflicting evidence on the optimal anesthetic (general vs. neuraxial) and analgesic regimens for TKA.
• Post-TKA pain management remains a significant challenge, impacting patient recovery and satisfaction.

Purpose of the Study:

• To review and synthesize recent evidence on anesthetic and analgesic techniques for TKA.
• To evaluate the comparative benefits and risks of different anesthetic approaches for TKA.
• To identify effective and safe analgesic strategies for managing post-TKA pain.

Main Methods:

• Systematic evaluation of recent high-quality studies and meta-analyses concerning TKA anesthesia and analgesia.
• Inclusion of diverse research, including clinical trials and population-based studies.
• Focus on outcomes such as morbidity, pain control, and patient recovery.

Main Results:

• Clinical data suggests neuraxial anesthesia is associated with lower morbidity compared to general anesthesia for TKA.
• A multimodal, opioid-minimizing analgesic approach, incorporating peripheral nerve blocks or peri-articular injections, is strongly supported.
• Ultrasound-guided regional analgesia techniques demonstrate cost-effectiveness and clinical efficacy.
• The IPACK block shows promise for addressing posterior knee pain post-TKA.

Conclusions:

• Recent evidence supports the use of neuraxial anesthesia and regional analgesia techniques for TKA.
• Opioid-sparing multimodal analgesia, utilizing regional techniques, is recommended for effective post-TKA pain management.
• Tailoring care pathways to local practices is crucial for maximizing TKA success, with ongoing research needed for emerging techniques like liposomal bupivacaine.
