Resolution of Hip Microinstability Caused by Everted Labrum Through a Targeted Intraarticular Anchor Repair...

Area of Science:

• Orthopedic Surgery
• Hip Arthroscopy
• Anatomic Variations

Background:

• Everted labrum is an anatomic variation linked to hip microinstability in patients with impingement-type pain.
• This condition occurs despite an otherwise intact labrum.

Purpose of the Study:

• To compare clinical outcomes of hip arthroscopy in patients with everted labrum-induced microinstability versus those with standard femoroacetabular impingement (FAI).

Main Methods:

• A cohort study (Level 3 evidence) compared 76 patients undergoing hip arthroscopy.
• Patients were divided into two groups: everted labrum (Group 1) and classic FAI with labral tears (Group 2).
• Data collected included Hip Outcome Score (HOS), Visual Analog Scale (VAS), and return to sports, with a minimum 24-month follow-up.

Main Results:

• Group 1 showed a higher prevalence of upsloping lateral acetabular rim (65% vs. 11%) and a significantly greater lateral center-edge angle (LCEA) (37.1° vs. 34.6°).
• No significant differences were observed in HOS or VAS scores between the groups at 6 and 12 months postoperatively.
• Postoperative return to sports outcomes were also comparable between the two groups.

Conclusions:

• Hip arthroscopy yields similar clinical and functional outcomes for everted labrum and FAI patients when treated with appropriate techniques.
• Effective management of the everted labrum, focusing on restoring the labral seal, is crucial for successful long-term surgical results.
• Recognition of this anatomic variant is essential for optimizing patient outcomes after hip surgery.
