Postoperative Pain Management in Total Knee Arthroplasty

Area of Science:

• Orthopedics
• Anesthesiology
• Pharmacology

Background:

• Total knee arthroplasty (TKA) is a common procedure for end-stage knee arthritis.
• Postoperative pain significantly impacts rehabilitation, patient satisfaction, and outcomes following TKA.
• Opioids are traditionally used but have significant adverse effects limiting their use.

Purpose of the Study:

• To review current postoperative pain management strategies for TKA.
• To evaluate the efficacy of multimodal analgesia in TKA patients.

Main Methods:

• Literature review of current postoperative pain management regimens for TKA.
• Analysis of multimodal analgesia components including preemptive analgesia, neuraxial anesthesia, peripheral nerve blockade, patient-controlled analgesia, local infiltration analgesia, and oral medications.

Main Results:

• Multimodal analgesia is identified as the optimal regimen for TKA perioperative pain management.
• This approach combines multiple medication types and delivery routes for superior pain relief.
• Multimodal analgesia improves clinical outcomes and patient satisfaction while reducing opioid consumption and adverse effects.

Conclusions:

• Multimodal analgesia is the gold standard for postoperative pain control after TKA.
• It effectively manages pain, enhances knee function recovery, and minimizes opioid-related complications.
• This comprehensive strategy leads to better overall patient outcomes and satisfaction.
