Midterm Outcomes After Labral Reconstruction in Revision Versus Primary Hip Arthroscopy: A Propensity-Matched Study

Area of Science:

• Orthopedic Surgery
• Hip Arthroscopy
• Labral Reconstruction

Background:

• Outcomes differ between primary and revision hip arthroscopy.
• Limited data exists comparing revision versus primary hip labral reconstruction, particularly for midterm results.

Purpose of the Study:

• To compare 5-year patient-reported outcomes (PROs) and survivorship between revision and primary hip labral reconstruction.
• To evaluate the efficacy of revision arthroscopic labral reconstruction.

Main Methods:

• Retrospective review of 72 patients (36 revision, 36 primary) undergoing hip labral reconstruction with minimum 5-year follow-up.
• PROs assessed using Nonarthritic Hip Score, International Hip Outcome Tool-12, and Hip Outcome Score-Sports Specific Subscale.
• Matched cohorts based on demographics, hip anatomy, and surgical factors; excluded patients with severe osteoarthritis or specific complications.

Main Results:

• Both primary and revision cohorts showed significant improvements in all PROs at 5-year follow-up (P < .01).
• Postoperative outcomes and achievement of clinically meaningful improvement thresholds were comparable between the two groups.
• The primary group had worse preoperative cartilage damage but higher baseline PROs.

Conclusions:

• Hip labral reconstruction provides durable, significant clinical improvements for both primary and revision cases over a minimum of 5 years.
• Midterm outcomes are comparable, supporting the use of revision labral reconstruction in appropriately selected patients.
• Revision hip arthroscopy demonstrates efficacy comparable to primary procedures.
