Purpose:

Evaluate whether intraoperative PRP injection improves outcomes after hip arthroscopy for labral tears compared to standard bupivacaine injection.

Methods:

Prospective study of 306 patients; outcomes measured pre-op, 3 months, and 2 years post-op via PRO scores and pain VAS.

Key Findings:

  • Both groups improved overall.
  • At 2 years, PRP group had slightly higher pain scores and lower modified Harris Hip Scores.
  • No difference in other PROs or revision/THA rates.

Conclusion:

Intraoperative PRP did not enhance clinical outcomes and may slightly worsen pain and function scores at 2 years.

What Does This Mean for Providers?

  • Routine use of intraoperative PRP during hip arthroscopy for labral tears is not supported by current evidence.
  • Consider cost-effectiveness and patient counseling before offering PRP injections.
  • Focus on established pain management techniques unless future data suggests otherwise.
