P204 - Tracing Outcomes and Survivorship Against Age and Gender Abstract in Hip Arthroscopy Surgery.
Abstract
Purpose
To compare patient-reported outcomes (PROs) of patients undergoing hip arthroscopy for FAI according to sex and age.
Methods and Materials
Prospectively collected data from February 2008 to September 2016 were retrospectively reviewed. Patients were included if they had a primary hip arthroscopy for FAI treatment and had minimum 2-year follow-up for the following PROs: modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score-Sports Specific Subscale (HOS-SSS), and Visual Analog Scale (VAS). Exclusion criteria were Tönnis grade > 1, LCEA ≤ 18°, previous ipsilateral hip surgery, and previous hip conditions.
Results
1,269 hip arthroscopies met the inclusion and exclusion criteria. Of these, 1,056 (83.2%) hips had minimum 2-year follow-up. 687 (65.1%) patients were females and 369 (34.9%) patients were males, with an average follow-up of 51.1±22.3 months. 674 patients were eligible for minimum 5-year follow-up, and 545 (80.9%) had follow-up at minimum 5-year. BMI and alpha angle were the only statistically significant differences between males and females. All groups, except for females and males ages >61 years, showed significant improvement in all PROs and VAS at minimum 2-year follow-up. This improvement was sustained at minimum 5-year follow-up. A comparison of age groups within the same sex demonstrated significant differences in PROs for females depending on age at latest follow-up. Females between 31-40 years old experienced significantly worse outcomes than females <21 years old. Likewise, females 41-50 years old also reported significantly worse outcomes than females <21 years old. Similarly, male patients <21 years old had significantly better outcomes than males ages 31-40, 41-50, 51-60, and >60 years old.
Conclusion
Although all patients had significant improvements in all PROs following hip arthroscopy, younger patients reported better postoperative PROs and lower rates of conversion to THA. Female patients reported similar levels of improvement in PROs compared to their male counterparts.
