P203 - Effectiveness of Femoroplasty, Labral Treatment, Iliopsoas Fractional Lengthening and Capsular Plication During Hip Arthroscopy
Abstract
Purpose
To determine if the combination of femoroplasty with labral treatment, iliopsoas fractional lengthening and capsular plication during hip arthroscopy (FLIP procedure) has favorable outcomes among young female patients.
Methods and Materials
Data between March 2009 and November 2014 were retrospectively reviewed. Female patients ages of 16 - 29 who had preoperatively reported outcome measures were included. Patients were excluded if they had a prior ipsilateral surgical condition, prior arthroscopy procedure or a preoperative Tönnis osteoarthritis grade greater than 1. Cases were matched on a 1:1 ratio by age, BMI, acetabular outerbridge classification and workers compensation status. Patients in the study group had a pre-operative lateral center edge angle (LCEA) between 18-29 degrees and underwent a FLIP procedure. Patients in the control group had pre-operative LCEA >30 degrees and had no FLIP procedure.
Results
Although there were significant differences LCEA between the FLIP group and the control group (p < 0.01), there were no significant differences in Tönnis angle between the groups. All 37 cases in each study group had significant improvement in modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score – Sports Specific Subscale (HOS-SSS), and visual analog scale (VAS), (all p<0.001) from baseline to two-year follow up. Between the two groups, there were no significant differences between preoperative scores and two-year follow up scores across all patient reported outcomes.
Conclusion
This study demonstrates that a cohort of young female patients with LCEA 18-29 degrees with the FLIP procedure when matched to LCEA > 30 with no FLIP procedure can have significant improvements from baseline to two-year follow up in PRO measures.
