The evidence for hip arthroscopy: grading the current indications.

Area of Science:

• Orthopaedic surgery
• Evidence-based medicine

Background:

• Hip arthroscopy is increasingly utilized for various hip pathologies.
• The evidence base supporting its efficacy requires critical evaluation.

Purpose of the Study:

• To systematically analyze the Level of Evidence and Grade of Recommendation for hip arthroscopy across different indications.
• To assess the quality of evidence supporting current hip arthroscopy practices.

Main Methods:

• A systematic literature review of PubMed and Cochrane databases was conducted in June 2010.
• Studies on hip arthroscopy efficacy were reviewed, categorized by indication, and assigned a Grade of Recommendation.
• A novel subscale was used to further characterize poor-quality evidence.

Main Results:

• Fair evidence (Grade B) supports hip arthroscopy for femoroacetabular impingement.
• Poor-quality evidence (Grade C) exists for acetabular labral tears, extra-articular lesions, septic arthritis, and loose bodies.
• Conflicting, poor-quality evidence (Grade C(c)) was found for hip osteoarthritis.

Conclusions:

• Hip arthroscopy is well-supported for femoroacetabular impingement, but evidence for most other indications is currently inadequate (Grade C or I).
• Higher-quality studies (Level I and II) are necessary to substantiate the expanding use of hip arthroscopy.
• The findings highlight the need for rigorous research to guide clinical decision-making in hip arthroscopy.
