Local Infiltration Anesthesia in Total Hip Arthroplasty: A Randomized Controlled Trial

Area of Science:

• Orthopedic Surgery
• Pain Management
• Anesthesiology

Background:

• Total hip arthroplasty (THA) is a common procedure for osteoarthritis, but postoperative pain can impede recovery.
• Local infiltration analgesia (LIA) is explored to alleviate pain and enhance rehabilitation after THA.
• Evidence on LIA's effectiveness in THA is conflicting, necessitating further investigation.

Purpose of the Study:

• To evaluate the efficacy of local infiltration analgesia (LIA) in managing postoperative pain following total hip arthroplasty (THA).
• To assess the impact of LIA on key recovery metrics in THA patients.

Main Methods:

• A blinded randomized controlled trial involving 108 patients undergoing THA.
• Patients received either LIA or standard care (non-LIA) during surgery.
• Outcomes measured included pain scores, blood loss, hospital stay duration, functional recovery, and patient satisfaction.

Main Results:

• No significant differences were found between LIA and control groups in postoperative pain at 24 and 48 hours.
• Blood loss, length of hospital stay, and functional outcomes at 3 and 6 months showed no significant variations.
• Patient satisfaction and complication rates were similar across both groups.

Conclusions:

• Local infiltration analgesia (LIA) did not demonstrate significant benefits for pain management after primary total hip arthroplasty (THA).
• LIA did not improve hospital stay duration, blood loss, functional outcomes, or patient satisfaction in this THA cohort.
• The study suggests LIA may not be a beneficial adjunct for routine pain management in primary THA.
