Does warming up improve surgical outcome in total hip arthroplasty?

Abstract

Purpose: Warming up prior to surgery has been shown to enhance surgeons' performance during laparoscopic procedures. It is unknown whether or not warming up prior to total hip arthroplasty (THA) will have a similar effect on surgical outcome.

Methods: We retrospectively evaluated the effect of warming up on the intraoperative outcome of 82 patients who underwent a primary THA with identical implants. The patients were divided equally into two groups. Group 1 (first case of the day) served as "warm-up procedure," while Group 2 (second case of the day) was the "post-warm-up procedure."

Results: We found no statistically significant difference when we compared cup abduction and anteversion angles, femoral offset, postoperative LLD, stem alignment, hip center of rotation and femoral stem canal fill between the two groups (p > 0.05).

Conclusion: Warming up prior to performing surgery does not make a difference for primary THA when performed by an experienced surgeon. However, these results may not reflect its effect on procedures that require fine motor skills or done by an orthopedic trainee or less experienced surgeons.
