Effect of Local Infiltration Anesthesia With Ropivacaine on Pain After Primary Total Hip Arthroplasty

Effect of Local Infiltration Anesthesia With Ropivacaine on Pain After Primary Total Hip Arthroplasty

Background: The Local infiltration analgesic (LIA) technique has been widely used to reduce opioid requirements and improve the patient's mobilization after total hip arthroplasty (THA). However, the evidence for LIA in THA remains to be clarified.

Purpose: To evaluate whether a single shot LIA in addition to a multimodal analgesic regimen reduces acute postoperative pain and opioid requirements after THA.

Inclusion Criteria:

• all patients receiving total hip arthroplasty in the study period

Exclusion Criteria:

• contraindications to receive spinal anesthetic, Dexamethasone or Acetaminophen.
• Patients who received general anaesthetic
• patients who will get a different operation than standard direct lateral surgery
• Patients with osteosynthesis to be removed in the same operation
