Prospective Single-Blinded Randomized Controlled Trial Comparing Pericapsular Injection Versus Lumbar Plexus...

Area of Science:

• Orthopedic Surgery
• Anesthesiology
• Pain Management

Background:

• Hip arthroscopy is the standard treatment for femoroacetabular impingement.
• Effective postoperative pain management is crucial for patient comfort and safety after hip arthroscopy.

Purpose of the Study:

• To compare pericapsular injection with lumbar plexus blockade for postoperative pain control after hip arthroscopy.
• To evaluate the hypothesis that pericapsular injection provides equivalent pain relief with fewer adverse effects.

Main Methods:

• A single-blinded randomized controlled trial involving 64 patients undergoing hip arthroscopy.
• Patients were randomized to receive either a lumbar plexus blockade or a pericapsular injection.
• Pain scores, time to discharge, narcotic use, and adverse events were assessed.

Main Results:

• No statistically significant difference in postoperative pain scores between the two groups.
• A trend towards lower pain was observed in the pericapsular injection group.
• No significant differences in narcotic demand, time to discharge, or major adverse events were noted.

Conclusions:

• Pericapsular injection is a safe and effective alternative for postoperative analgesia after hip arthroscopy.
• It provides comparable pain relief to lumbar plexus blockade.
