  Purpose

The purpose of the study is to compare the effects of per-operative local infiltration analgesia with ropivacaine 0,2 % (150 ML) versus placebo on acute postoperative pain intensity after total hip arthroplasty.

The hypothesis is that local infiltration analgesia reduces the acute postoperative pain intensity.

Primary Outcome Measures:
  • Postoperative pain scores on the Visual Analog Scale (during walking) [ Time Frame: up to 8 hours ]

Secondary Outcome Measures:
  • Additional analgetics measured as cumulated amount i mg [ Time Frame: up to 8 hours ]
  • Time spend in hospital measured as nights after surgery [ Time Frame: At discharge (mean 2-3 nights) ]
  • Number of Participants with Adverse Events as a Measure of Safety and Tolerability [ Time Frame: up to 8 hours ]
  • Postoperative pain scores on the Visual Analog Scale (at rest) [ Time Frame: up to 8 hour ]

Detailed Description:
In spite of being one of the last century's most successful surgical procedures in treatment of advanced osteoarthritis total hip arthroplasty is still associated with postoperative pain and delayed rehabilitation. We therefore decided to evaluate the effects of per-operative local infiltration analgesia with ropivacaine 0,2 % (150 ML) versus placebo on acute postoperative pain intensity in a well defined, multimodal, fast-track setup after hip arthroplasty. The technique is widely used as standard treatment in many European centers despite its limited evidence.
