Arthroscopic acetabuloplasty and labral refixation without labral detachment

Area of Science:

• Orthopedic Surgery
• Hip Arthroscopy
• Femoroacetabular Impingement

Background:

• Arthroscopic acetabuloplasty traditionally involved labral detachment for acetabular rim access and resection.
• Recent advancements allow acetabuloplasty and labral refixation without detachment if the chondrolabral junction is intact.

Purpose of the Study:

• To compare outcomes of arthroscopic acetabuloplasty with labral refixation without detachment versus with detachment.
• Evaluate patient-reported outcomes and revision rates at a minimum 2-year follow-up.

Main Methods:

• Prospective cohort study (Level of evidence, 3) comparing two groups undergoing hip arthroscopy.
• Study group: acetabuloplasty and refixation without labral detachment (intact chondrolabral junction).
• Control group: acetabuloplasty with labral detachment and refixation. Assessed using 4 PROs and VAS pain score.

Main Results:

• Both groups showed significant improvement in PRO scores and decrease in VAS pain postoperatively.
• No statistically significant difference in the change of PRO or VAS scores between groups.
• No significant difference in revision surgery rates between the study (7/group) and control (8/group) groups.

Conclusions:

• Arthroscopic acetabuloplasty and labral refixation without detachment yield similar patient outcomes to procedures with detachment.
• This technique is a viable and effective option for pincer and combined-type impingement when the chondrolabral junction remains intact.
