What this trial studies

This observational study aims to compare the effectiveness of three different regional anesthesia techniques for pain management in patients undergoing total knee replacement surgery. Participants will receive selective spinal anesthesia followed by one of the three nerve blocks: Femoral Nerve Group+IPACK, Saphenous Nerve block+IPACK, or Subsartorial Block. The study will evaluate the pain control experienced by patients in the 24 hours post-surgery to determine if any technique provides superior analgesia. The research will involve monitoring patients and administering standard pain relief medications as needed.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old scheduled for elective total knee replacement surgery.

Not a fit: Patients under 18, those requiring general anesthesia, or individuals with certain medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management strategies for patients undergoing knee replacement surgery.

How similar studies have performed: Previous studies have shown varying success with different regional anesthesia techniques, but this specific comparison is novel.
