Best multimodal analgesic protocol for total knee arthroplasty

Area of Science:

• Orthopedic Surgery
• Anesthesiology
• Pain Management

Background:

• Total knee arthroplasty (TKA) is a common procedure aiming for pain-free functional restoration.
• Peripheral nerve blocks enhance TKA outcomes, improving ambulation and reducing hospital stays.
• The adductor canal block is increasingly favored over femoral nerve blocks due to safety concerns.

Purpose of the Study:

• To evaluate the efficacy of different peripheral nerve block techniques for pain management in TKA.
• To determine the optimal analgesic protocol for patients undergoing total knee arthroplasty.

Main Methods:

• Review of current literature on peripheral nerve blocks for TKA.
• Comparison of femoral nerve block and adductor canal block efficacy and safety.
• Analysis of multimodal pain management strategies including neuraxial anesthesia and continuous adductor canal block.

Main Results:

• Peripheral nerve blocks significantly reduce pain scores and improve early mobilization post-TKA.
• The adductor canal block presents a potentially safer alternative to femoral nerve blocks.
• A multimodal approach combining neuraxial anesthesia and continuous adductor canal block shows promise.

Conclusions:

• Intraoperative neuraxial anesthesia with a continuous adductor canal block and multimodal analgesia is recommended for TKA.
• This protocol aims to optimize pain control, functional recovery, and patient satisfaction after knee replacement.
• Adductor canal block offers a favorable risk-benefit profile for TKA pain management.
