Abstract
Purpose: To compare the changes in labral size after primary hip arthroscopy between patients requiring revision surgery and those did not.
Methods: Data collected between August 2016 and September 2021 were retrospectively reviewed. Patients diagnosed with femoroacetabular impingement syndrome and undergoing primary and revision hip arthroscopy at our institute were included in the revision group. Exclusion criteria were Tönnis grade >1, concomitant hip conditions, and incomplete magnetic resonance imaging (MRI) data. Patients who did not undergo revision surgery or conversion to total hip arthroplasty at minimum 2-year follow-up were matched in a 1:2 ratio and included in the control group. The labral size (width and height at 11:30, 1:30, and 3:00) on MRI (noncontrast, 3.0 T) before and after 12 months of primary surgery was compared.
Results: Twenty-one patients were included in the revision group, and 42 patients were matched in the control group. In the revision group, significant reduction in labral width and height at 11:30 and 1:30, and labral width at 3:00 was observed at 12 months after primary hip arthroscopy (all with P < .05), whereas the control group did not show significant difference of changes in labral size (all with P > .05). Smaller postoperative labral width at 1:30 and 3:00 was observed in the revision group compared with the control group (all with P < .05). The revision group presented with greater reduction of labral width at all 3 positions and labral height at 1:30 compared with the control group (all with P < .05).
Conclusions: Patients requiring revision surgery after primary hip arthroscopy for femoroacetabular impingement syndrome presented with smaller postoperative labral size (less than 1 mm difference) and greater reduction of labral size (at or less than 1mm difference) on MRI 12 months after primary surgery compared with those patients that did not require later revision surgery.
Level of evidence: Level III, retrospective case control.
期刊介绍：
Nowhere is minimally invasive surgery explained better than in Arthroscopy, the leading peer-reviewed journal in the field. Every issue enables you to put into perspective the usefulness of the various emerging arthroscopic techniques. The advantages and disadvantages of these methods -- along with their applications in various situations -- are discussed in relation to their efficiency, efficacy and cost benefit. As a special incentive, paid subscribers also receive access to the journal expanded website.
